You Could Do This with Your Eyes Closed (… and You Should)
Dana Tomlin
University of Pennsylvania

Having managed to avoid real work for several decades now in favor of a hobby that’s been sustained by lots of students in lots of disciplines with lots of enthusiasm for geospatial thinking, I’m convinced that this enthusiasm has less to do with the particular nature of those disciplines than the general nature of that thinking. There’s just something about the right-hand side of the brain that can make its use as addictive as it is productive. By recognizing and responding to this in both the development and the application of our ever-evolving toys … I mean tools, those tools really can feel a bit more like toys and our work a bit more like a hobby. Let me give you some examples.

Bryson Koziell
CDM Smith

In March of 2016, Pennichuck was engaged by the New Hampshire Department of Environmental Services to assess options to extend its public water to 376 homes with wells contaminated with perfluorooctanoic (PFOA) in the town of Litchfield, NH. Pennichuck was engaged and the responsible party to prepare bid-ready plans and specifications in 13 weeks for over 10 miles of water main and 400 customer services. Pennichuck leveraged information using GIS, GPS, mobile technologies, and other company resources developed through asset management to complete the work on time and under budget.

Do More with Less: Getting to Know Data Interoperability Extension for ArcGIS and FME Desktop
Alexander Stepanov
Niels la Cour
University of Massachusetts Amherst

ESRI ArcGIS is a powerful geospatial platform that includes desktop, server, Web, and Cloud components. In general, operations with data within the platform are straight forward due to common data formats and standards. In many cases, however, users need to bring in data from external sources/organizations and multiple formats such as CAD, BIM, Excel, social networks, and XML into the ArcGIS environment. ArcGIS has a Data Interoperability extension that allows users to build powerful Extract-Transform-Load (ETL) and automation workflows. This software is also available as a stand-alone FME Desktop version. In this hands-on workshop, we will show practical examples of bringing data from/to CAD (utilities, architectural drawings), harvesting and processing CAD attributes, and creating complex PDF reports and data maintenance automation workflows (bulk attribute renaming, remapping data schema, QAQC, merging multiple data sources, etc.). The workshop targets users with some ArcGIS Desktop experience. Some experience with Model Builder is useful. No programming experience is required.

Vermont Afterschool works to expand, strengthen, and improve access to out-of-school time programming for children and youth in the state. To help fulfill our mission, we maintain a database of all afterschool and summer learning programs. Using the mapping capabilities available with Tableau Public, we were able to create an interactive Web map to display all such programs in the state. This talk will cover our process of using Tableau in conjunction with Mapbox geocoding services to create and maintain the map. Check out the map here.

Statewide Parcel Data in Vermont: It’s Finally Happening!
Leslie Pelch
Vermont Center for Geographic Information

Members of the Vermont GIS community have been actively talking about a coordinated, statewide, parcel data development project for almost four years. With direction and funding from the Agency of Transportation (and the Federal Highway Administration) and additional support from most state agencies and departments, the project is truly underway in 2017! Join us to learn a little more about the history and future of parcel mapping in the Green Mountain State.

The Meaning of Meandering
Dana Tomlin
University of Pennsylvania

Consider the path that you’ve followed over the past week or so: the path from one spot to another in a given room, from one room to another in a given building, from one building to another in a given neighborhood, and so on. You get the idea. Now suppose that this path were to be recorded as a series of digital waypoints. The result would be a set of tracking data not unlike that which might be associated with the motion of an animal, a vehicle, a weather event, a crime spree, or even a wandering eye. So how might inferences be drawn from such patterns of movement over space and time? While ArcGIS can certainly be used to animate tracks, could it also be instructed to “see what you see” when you watch those animations? Could it distinguish meaningful places, for example, from transitions among those places? If so, then perhaps each place could be characterized in terms of things like duration and revisitation. But how can that be done when these places are inherently imprecise and emergent, coming into focus themselves only as a result of things like duration and revisitation? This presentation offers a straightforward description of recent efforts to address such questions with a newly developed ArcToolbox tool for spatiotemporal analysis.

GoTime Mobile Application Development: A Solution for Accessible Real Time Travel Information
Mark Haberle
VHB

MassDOT’s Real-Time Traffic Management (RTTM) system consists of over 700 miles of statewide highway and more than 137 signs displaying travel times to over 300 destinations. Close to 2.2 million motorists view the signs daily. MassDOT engaged VHB to design, develop, and deploy the GoTime mobile application to complement the ongoing rollout of the RTTM system.

The GoTime mobile application enhances the RTTM’s information dissemination objectives by providing a modern, publicly accessible, mobile component to the RTTM system. By giving drivers a tool with which to make informed travel decisions, the GoTime mobile application supports MassDOT’s objective to create a cleaner, more efficient, and sustainable transportation system.

The project objective, as set forth by MassDOT, was to rapidly develop and deploy a visually appealing and easy-to-use mobile application (for both iOS and Android) showing the same real-time travel information displayed on the RTTM signs. GoTime provides a simple map-based interface that allows users to view the currently posted travel-time information for routes displayed on selected RTTM signs. Users can define, identify, and store favorite routes for rapid access prior to their travel.

The application uses static route data (link geometry) and dynamic travel-time data, both provided via the freely available MassDOT RTTM application programming interface (API). Building against the API allowed the developers to create a solution that seamlessly integrates the state’s ongoing rollout of additional RTTM devices and related travel time data as it becomes available.

This presentation will overview the challenges and innovations behind this successful deployment.

Beyond Town and Gown: Undergraduate Geographic Research to Support City-College Partnerships
Chris Brehme
Chris Cusack
Keene State College
Will Schoefmann
City of Keene

Through a senior capstone course, Keene State College Geography Department faculty and students annually partner with City of Keene staff on planning, conservation, and recreation projects. More than 10 projects over 10 years have provided GIS and research skills for undergraduates, and valuable information for City initiatives. Armed with a toolbox of skills in GIS, statistics, data collection, and analysis, students have monitored and mapped City recreational resources, housing, and zoning issues, as well as critical conservation areas. Results are presented to the public via community forums and made available as in-depth illustrated reports on College and City websites. Professionals and residents throughout the community reference these resources for ongoing decision-making and planning processes. Future efforts will be made to formalize the partnership, standardize methods, and develop multi-year projects that geography students can regularly update and monitor. Web mapping and cloud-based data storage will be fundamental to maintaining this collaboration. ArcGIS Online applications will provide real-time outreach to the public, while giving students access to a broader range of relevant GIS skills.

Using Time Series of Remotely Sensed Imagery to Model Land Cover Change in South America
Caroline Curtis
Valerie J. Pasquarella
Bethany A. Bradley
University of Massachusetts Amherst

In the southern hemisphere, non-native pines are established in plantations and have escaped and spread into the surrounding ecosystem, altering the ecosystem and threatening native species. Despite the potential risk from invasive populations, little is known about the current or historical extent of non-native pine or the land cover lost from conversion. The large spatial extent and high detectability of non-native pines provides a unique opportunity to apply remotely sensed data to quantify current land cover and model land cover change through time. I downloaded all high quality Landsat images for eight scenes in Chile. For each image, I created reference data based on historical aerial photos from Google Earth. I used time series models to quantify when land cover changes occurred and the Random Forest algorithm to classify images and create land cover maps. By modeling the time series of images, I am able to map the current and historical location of pines and identify the spatiotemporal patterns of pine dispersal and land cover change.

Analysis with ArcGIS Online

Using Smart Phone Photos and Cloud Storage for Rapid Data Collection and Further Integration with ArcGIS Online
Alexander Stepanov
Niels la Cour
University of Massachusetts Amherst

In this presentation we will discuss an approach to conduct a rapid data inventory using photos taken by smart phones, cloud storage (BOX) as a collaborative means to manage attribute information, and ArcGIS Online to integrate collected data. Key features of this approach are that it’s scalable horizontally (easy to expand data collector teams) and that BOX plays the role of image management system. Finally, BOX API and ArcGIS Online API are used via FME technology to integrate data. We also will discuss the use of 360° images for data collection. We will use the case of campus signage inventory to demo this approach.

Challenges in Structuring the GIS Curriculum
Forrest Bowlick
University of Massachusetts Amherst

Degrees in Geographic Information Science are more common, and more diverse in structure, than ever. With the wide range of applications of GIS, and the variant methods and approaches in teaching GIS, challenges emerge in defining adequate structures for the curriculum that balance the systems, science, and tool-based applications of GIS. This talk will outline these challenges and present questions to consider in curriculum construction and review.

But how do you ensure that your applications offer the best experience and are easily adopted? In this session, we’ll discuss some best practices to consider when building and deploying Web applications for your organization. We will talk about User Experience, User Interfaces, and some common pitfalls, and demonstrate some high-quality examples.

Blended Learning for GIS Instruction in a Liberal Arts Context
Scott Gilman
Jon Caris
Smith College

The Smith College Spatial Analysis Lab (SAL) faces a challenging situation teaching GIS at a liberal arts college with no Geography department and only one dedicated GIS class. The SAL supports faculty from dozens of departments to integrate GIS into their classes. Students in these classes have a wide range of GIS experience and different levels of digital literacy. Furthermore, faculty have limited class time for GIS instruction, and often prefer to spend time discussing how spatial analysis contributes to their discipline. Thus, opportunities for students to acquire technical skills needed to effectively use the software are quite limited.

To improve learning outcomes in this model, the SAL is developing a series of blended learning modules that will help students from all disciplines to learn GIS outside of class. In addition to video tutorials, Smith’s modules include interactive applets that demonstrate spatial analysis tools in a limited interface before introducing students to a more robust application, such as ArcGIS. The modules also include immediate assessment of concepts and tools. In this talk, we present the first blended learning module on introductory cartographic design, and feedback from testing it in classes and workshops from the past academic year.

DDACTS: A Data Driven Approaches to Crime and Traffic Safety in York, Maine
Brett Horr, GISP
Town of York

The Town of York, Maine has employed the DDACTS law enforcement operational model to encourage the creation of hot spots mapping specific crime and traffic crash data to determine the most effective methods for deploying law enforcement and other resources. Drawing on the deterrent value of highly visible traffic enforcement and the knowledge that crime often involves motor vehicles, the goal of DDACTS is to reduce crime, crashes, and traffic violations. This presentation will introduce how and why the York Police Department has employed the DDACTS model, what the data revealed after it was mapped, how GIS and Automatic Vehicle Location (AVL) services and the ArcGIS Collector App have changed how the York Police Department operates.

GIS Helps to Define Possible Stormwater Detention Sites in the Pocantico Watershed
Peggy Minnis
Pace University

Flooding along the Pocantico River, a small tributary of the Hudson River, has resulted in closed main roadways, property damage, and other negative flood effects. The watershed committee wondered if Pace’s GIS class could help define where stormwater could be detained. The class developed maps to suggest where detention sites might work, using lidar from Westchester County, parcel data, and site visits.

Geospatial Development in Government Human and Social Service Programs
Sam Wear
Westchester County GIS

While recognizing the many geospatial technologies advancements made over the past thirty years, one area of local government that continues to see limited deployment of GIS applications are the human and social services. The reasons for the slow uptake are many, some of which are obvious and justifiable, but evolving opportunities for broadening GIS development in government social services programs are promising based on advancements in Web mapping, vehicle and mobile technologies, increased data availability, and a growing understanding among administrators on the value of geospatial technologies.

With appropriations that often dwarf other local government department operating budgets, human and social services include broad program areas such as, but not limited to, the following: public assistance, welfare, special needs, disability programs, housing and homeless services, child protection services, and, just as important, the many contracted services governments use to assist in administering programs.

This presentation will provide an overview of ongoing discussions and work with Westchester County GIS towards building GIS/geospatial in human and social services program areas. While government human and social service programs may be phenomenally different in structure and administration across New England, many of the issues and potential GIS/geospatial solutions are conceptually similar.

Trustees of Reservations

Facing increasingly daunting projections for the potential impacts of climate change, coastal managers are seeking tools to help them prioritize investments in resiliency and develop strategic management plans. The Trustees of Reservations (TOR), which holds over 8,000 acres of publicly, historically, and ecologically important properties along the Massachusetts coast, partnered with Woods Hole Group to conduct a Coastal Vulnerability Assessment (CVA). As a part of the CVA process, ArcGIS was used in the development of a Coastal Vulnerability Index (CVI) for each of the coastal TOR properties in Massachusetts. The CVI combines the probability of inundation (from a highly-resolved hydrodynamic model) with consequence of inundation scores (developed in collaboration with TOR managers) for all TOR assets (infrastructure, historical, and ecological). The CVI facilitates ranking of the most susceptible assets on each property and across all properties, and provides a basis for TOR to prioritize resiliency and adaptation projects that ensure TOR’s ability to carry out its mission and use resources most efficiently. This presentation details the application of an ArcGIS workflow not only as a tool to assess and visualize vulnerability data, but also as a management framework to plan and prioritize coastal adaptation projects.

Exploring Spatial Patterns and Relationships in GIS Datasets for Vision Zero Boston
Youshe Li
Department of Innovation and Technology, City of Boston

Spatial statistical methods have been used to explore the question of what data should dictate the engineering focus of the Boston Transportation Department and to understand how well 311 Engineering Requests align with other data such as Traffic Crashes, Safety Concerns, and Waze Traffic Jams. Statistically, there are clusters on the maps for 311 Engineering Requests, Traffic Crashes, and Safety Concerns at a 95% confidence level, and the clusters for 311 Engineering Requests are spatially correlated / aligned with those for Traffic Crashes and Safety Concerns also at a 95% confidence level. The Kernel Density Estimator and Ripley’s K Function together indicate we would (very likely) continue to have more Traffic Crashes, more 311 Engineering Requests, and more Safety Concerns in these clustered areas in the future. Visit the City of Boston Web site for more details.

Change Detection in Coastal Geomorphology Using Lidar Data
Patrick Cunningham
Blue Marble Geographics

Technology improvements over recent years have seen the cost of 3D point-cloud data acquisition decrease and consequently the coverage and availability expand dramatically. Hardware miniaturization has given rise to on-demand data collection with unmanned aerial vehicles (UAVs) taking the place of manned fixed-wing or rotary aircraft in the collection process. As a consequence, point cloud data is increasingly used as the raw material for precise measurement and visualization of change over time. Nowhere is this process more evident than in coastal areas where shifting patterns of erosion and deposition can have devastating effects on shoreline communities. In this presentation, we will examine an area on the coast of the state of Maine that has been subject to significant beach erosion. Using point cloud data collected over a five-year time period, we will explore the procedure whereby the raw data can be processed to create precise bare-earth models and how the difference between these surfaces can be calculated and visually represented to show areas of significant erosion or deposition.

Child maltreatment is one of the most challenging public health issues facing families in Massachusetts, which has one of the highest child maltreatment rates nationally. As the Commonwealth’s leading family support organization, the Children’s Trust of Massachusetts (CT) works on preventing child abuse by supporting parents and strengthening families. CT is currently developing an expansion of their existing Family Centers, which are place-based, family-centered, multi-generational service hubs that provide universal access to families with young children, in the form of play groups, parenting education, care coordination, and support groups.

The ambitious maltreatment prevention initiative would operate in 10-15 sites across the state, with the Family Centers serving as the focal points. Prior to any expansion, it is useful to document the geospatial distribution of child maltreatment risk across Massachusetts, and whether existing locations of Family Centers are effectively placed to maximize access to services among target populations that are most in need. Our study aimed to: 1) Identify the geospatial clusters of child maltreatment counts and rates at the zip code level for the entire state by conducting a five-step hotspot analysis approach in a Geographic Information System (GIS); and 2) identify areas with a high child maltreatment risk but low access to existing Family Centers by measuring travel time through network analysis in GIS.

Our findings will allow policymakers and the CT to better understand the landscape of child maltreatment risks in Massachusetts, and provide recommendations on the geographic and strategic placement of future Family Centers in Massachusetts to ensure prevention programs are best targeted to under-served areas with a high risk of child maltreatment.

Ash Trees Illustrated at SUNY Potsdam to Prepare for the Emerald Ash Borer
Matthew King
Isaac Auslander
Cayden Snow
SUNY Potsdam

The Emerald Ash Borer (EAB) has continued to pose a significant risk as an invasive species to any ash tree population it meets. With the city of Syracuse, N.Y. experiencing the devastation associated with this invasive species, the EAB is now close enough to St. Lawrence County, N.Y. and poses a risk to the resident ash species. The goal of our research project was to identify ash trees that would pose a threat to the campus community if they became infected and fell on the campus of SUNY Potsdam, N.Y.

Using Collector for ArcMap, we collected ash tree locations on foot and saved them to a map created on ArcGIS Online to georeference ash trees to paths and roadways around campus. Categorizing the trees into three categories by visible damage, we could mark the trees with the highest risk to an EAB infestation.

Having tree data from 2005 showing 1052 total trees on campus, we compared the ash trees in our recent data collection to show the percentage of ash population. We found 110 ash trees present, which represents 10.46% of the tree population. Of the 110 ash trees annotated, we found 17 of them to be within proximity of pedestrian walkways or campus roads. These 17 trees will need increased supervision and possibly removal soon, in order to reduce the risk to the student population. Continually updating the tree database on campus will allow for more accurate data analysis needed for proper identification of at risk areas.

Watershed Impact Assessment of Proposed Dairy Farm Expansion
Alyssa Bueno
Skidmore College

The October 2016 proposal to expand Cranberry Creek Dairy’s Concentrated Animal Feeding Operation (CAFO) was met with a six-month moratorium to allow for public input and environmental assessments. Cranberry Creek Dairy is located in Dunn County, Wisconsin - an area surrounded by state public lands and waterways. The expansion would mean increasing the current operation from 1720 to 7150 dairy cows.

The purpose of this study is to use GIS applications to model nitrogen and phosphorus (P) transport within a watershed from non-point source pollution. Modeling nutrient loading is important toward understanding algal blooms in relation to the practice of manure spreading in CAFOs. Manured fields are found to contain several times more P than non-manured fields. The methods for this analysis are broken down into two main groups: 1) ArcMap work in isolating the spreading lands and 2) OpenNspect analysis. All of the data acquisition and manipulation for this project has been completed. For a more complete analysis, I am currently working with software developer Dave Eslinger from the National Oceanic and Atmospheric Administration to work out some OpenNspect kinks. The expected results will include accumulated runoff (L), accumulated nitrogen (kg), nitrogen concentration (mg/L), and accumulated sediment (kg).

This project will have a larger implication on CAFOs throughout the state of Wisconsin to improve the Department of Natural Resources’ Nutrient Management Plan and increase regulations on wastewater outputs.

International Aid Projects Visualization and Analysis with Customized Thiessen Polygons
Yujie Wang
Clark University

This GIS project used a more complex algorithm of Thiessen polygons to analyze and visualize the complicated relationship between funding from various donor countries and spatial locations in any specific country using open data on international aid projects from AidData. Even though Thiessen polygons or Voronoi Polygons have been widely used for decades, there is not a tool solution in any publicly available GIS software to generate Thiessen polygons that are constrained by irregular boundaries. Using this customized algorithm of Thiessen polygons, this project took Timor-Leste, a country in South Asia, as an example to analyze and visualize funding distribution of various donors in this country. In addition, this project was purely developed with open source packages. Therefore, this presentation not only shows this sophisticated Voronoi approach considering geospatial boundaries, but also demonstrates the capability of open-source GIS to solve complicated problems. Besides introducing GIS contents, this presentation will also introduce three modes of visualizing funding distribution of international aid in order to remind attendants that the designs of GIS applications need to consider different assumptions on data.

 
UAV Imagery Processing Effects on NDVI Values at Different Spatial Resolutions

Bridgewater State University

Orthophotos created from UAV images collected during the 2016 growing season in southeastern Nebraska were developed using Esri’s Drone2Map software using GSD values of 7, 14, 21, and 28 cm. The objectives of the study are to 1) test whether modifying GSD during orthophoto construction has a varying effect on band statistics according to imagery date (crop greenness) or 2) landscape position. A third objective 3) is to determine if nearest-neighbor resampling of digital numbers (to 7, 14, 21 and 28 cm) using an input orthophoto constructed using base imagery GSD resolution of 7 cm differed from orthophotos originally constructed at corresponding GSD resolutions.

Satellite-derived Areal Metrics and Improved Mapping of Coastal Wetlands
Adam Laybourn
Stephanie Weber
Battelle

Traditionally, the mapping of wetlands around the Great Lakes has been labor intensive, entailing in-field observations and sampling. Remotely sensed imagery can expedite efforts to identify and map vegetation types associated with Great Lakes coastal wetlands. This is greatly needed to inform current federal and state efforts to affect specific areas of coastal wetlands. The US Environmental Protection Agency’s Great Lakes Restoration Initiative (GLRI) has a Five Year Action Plan published in September 2014 that includes, as a measure of progress, the “number of acres of Great Lakes coastal wetlands, protected, restored, and enhanced by GLRI-funded projects.” This project’s goal was to develop a semi-automated approach to use the most up-to-date satellite data in conjunction with other supporting information to analyze the areal extent of Great Lakes coastal wetlands.

A Retrospective Analysis of the Effect of Proximity to Major Roadways on Lung Function Post-Lung Transplant
Jennifer Gaudreau
Krystal Pollitt
University of Massachusetts Amherst

Traffic-related air pollution (TRAP) has contributed to increased rates of morbidity and mortality in a number of populations. Many studies have reported an association between TRAP and a variety of illnesses including chronic lung allograph dysfunction (CLAD), bronchitis obliterans syndrome (BOS), respiratory diseases, and cancer. Lung transplant recipients are a vulnerable population with increased risk of developing CLAD or BOS post-transplant. Forced expiratory volume in one second (FEV1) is a proxy for lung function. The objective of this study is to evaluate the association between proximity to major roadways from place of residence and the outcome of FEV1. 825 lung transplant patients were obtained from Toronto General Hospital between 2002 and 2012. Geographical coding was performed for 517 patients who lived in South Ontario Canada using ArcGIS 10.2. Excluding ex vivo perfusion and unilateral transplant recipients, 364 bilateral lung transplant patients were followed one year post-transplant. Cox proportional hazards models were used to evaluate the association between total major road length and FEV1 outcomes with SAS 9.4 statistical software. Covariates included diagnosis disease, acute rejection within 6 months, azithromycin use, cytomegalovirus mismatch status and predicted lung capacity. Proximity to major roads was evaluated continuously and categorically with use of buffer sizes surrounding patient residence. Patients were categorized and 73, 91, 88, and 57 patients had maximum total major road length density (TMRLD) within buffers of 100m, 100-300m, 300-700m, and 700-1000m respectively. The adjusted HR for percent predicted maximum FEV1 for patients with maximum TMRLD of 100m was 1.457 (p-value 0.045).

   
Geospatial Analyses of Agricultural Runoff and Water Resources in New York State

Water quality in New York State is dependent upon many factors, including pesticide and fertilizer use in agricultural areas. This agricultural pollution is often difficult to source, but can have far-reaching consequences, as the runoff from these agricultural establishments is washed into waterbodies. This project uses GIS methodology to determine the most likely flow pathways for such pollution, and combines known pollution hotspots in New York with rainfall data to create likely runoff models. This project will increase our understanding of the way in which agricultural pollution is disseminated into the environment.
