The Interface Design Challenge of Neighborhood Crime Mapping -City of Tigard, Oregon

Web-based crime mapping and reporting applications present a number of the persistent design challenges that confront GIS practitioners charged with providing the public with access to meaningful geospatial information. While reported crime data is typically available in an evolved structure of classifications, categories, and definitions, many organizations continue to struggle to expose it through sufficiently coherent and simple graphical user interfaces. To deliver an effective crime mapping application, a development team must:
· Distill and aggregate domain specific spatial data into a presentation format that can be quickly and easily understood by a lay audience;
· Provide straightforward and highly intuitive means for users to search, filter, visualize, and review this data;
· Find ways to integrate the element of time, allowing users to view both data trending and conditions at particular moments;
· Avoid oversimplifying information or presenting information in a manner that may be misleading or easily misinterpreted.
In an attempt to tackle some of these challenges -in particular aggregation of crime data and display of multiple types of crimes- the City of Tigard has employed some of the latest dynamic web mapping tools and GIS technologies (ESRI’s ArcGIS Server, and the associated Flex API), to create a highly focused and easy to use crime visualization tool for its emerging Neighborhood Networks program. This presentation will discuss the objectives, design, development, and challenges of developing public-facing GIS applications with a focus on the City of Tigard’s experience with this dynamic web-based neighborhood crime application.

Migrating Your Existing Parcel Data into ESRI’s Cadastral Fabric

Like many other county and state governments, the Blaine County GIS department worked to develop a GIS shapefile consisting of all the parcels in the county. This project was started with a Local Government Startup Grant that included the program AV Parcel. Through this process, which included hiring contractors, turn over and an eventual AV Parcel blow up, the resulting shapefile was complete but had a great number of gaps and overlaps in the polygons. The Blaine County GIS department was presented with a new editor/feature within the Survey Analyst Extension called Cadastral Fabric Editor.

The Blaine County GIS department purchased the survey analyst extension in the hopes of importing its existing parcel shapefile and completing a positional accuracy review of its data utilizing the features of the Cadastral Fabric. The result would be a seamless parcel layer that also contained accurate positions. After many trials and tribulations of importing the existing parcel shapefile into the cadastral fabric, a method was devised and successfully implemented. Within six weeks Blaine County GIS went from working in a shapefile to working in the fabric to fix all the gaps, overlaps and position accuracy. This presentation will discuss the method used to complete this transition. The discussion will include the challenges of the importing process, of working in the fabric and ways to overcome them

Chris Corwin

Chris Corwin is the newest addition to the Blaine County GIS department. His main duties as a GIS specialist is to update and maintain the land records, road files and address points for the Emergency Communications Department for the E911 CAD system. Chris came to Blaine County after earning a GIA certification from Boise State University and working as a GIS analyst intern for the Rocky Mountain Research Station and completing GIS work for the Health Science Department at BSU. Chris was tapped for learning the Cadastral Fabric Editor and using it to update Blaine County’s parcel data. After some training and a good deal of thrashing through the fabric environment, Chris has become the main editor of the parcel data in the fabric and responsible for completing the positional accuracy review for the county.

How Hard Can this Be?; The trials and tribulations of setting up and executing a project to track long haul trucks using GPS

Since 2004, the Lane Regional Air Protection Agency (LRAPA) in Springfield, Oregon has been working with the U.S. EPA on a project designed to reduce diesel emissions from heavy-duty trucks that idle in our communities. The project helps fund the addition of auxiliary power units (APUs) on trucks in order to provide a source of power for driver comfort systems while allowing the main engine to be turned off instead of idling. These APUs save 90% of the fuel that idling consumes and produce significantly less emissions than the main engine would.

In 2005 LRAPA partnered with LCOG’s Geographic Information Systems (GIS) group to provide analysis of how, when, and where these APUs were being used. Our goal on the project was to collect and analyze data to determine how many hours the APUs were in use, where these units were turned on, and calculate fuel and emissions reductions arising from the use of APUs. To accomplish this we employed a custom GPS tracking device linked to the APUs installed on a subset of trucks in the study to track the time and place that the APUs were in use. The tracking device included cellular phone based data uploading capability which allowed us to view the tracked trucks’ status in real time and download data for analysis remotely. Initially, this seemed to us a straight-forward GPS tracking and GIS analysis project. We soon learned that it would be anything but easy. This presentation tells a tale of perseverance and, eventually, a successful outcome to a difficult and unpredictable project.

Generating Shade Credits: Using GIS to Support Cost-Effective Water Quality Management

Clean Water Services in Washington County Oregon was issued a watershed–based National Pollutant Discharge Elimination System permit by the Department of Environmental Quality. This permit allows a watershed wide approach to managing water quality in the Tualatin River watershed. GIS is being used to link watershed-scale planning, permitting, project implementation and evaluation, and adaptive management through monitoring. Using GIS techniques scientist and managers are able to efficiently establish and prioritize water quality projects. High quality GIS data can be applied to multiple water quality management projects therefore reducing data collection and processing cost.

Adam Fleenor

I am currently a Water Resource GIS Specialist for Clean Water Services in Washington County Oregon. I have a BS in geography and environmental studies from the University of Oregon. I sit on the Tualatin River Watershed Council and its Restoration Committee.
Previously, I have worked for the Oregon Department of Forestry and Lane County Public Works.
