GIS in Action 2019 has ended
Welcome to the 27th annual GIS in Action Conference!

GIS technology and professionals are at work around the clock to support our basic needs and our livelihoods. From directing emergency responders to the scene of an accident, to synchronizing trading on Wall Street, to building 5G networks that support self-driving cars, geospatial data and technology helps us understand our environment and improves the quality of our lives.

Whether you are a LiDAR analyst working on risk mitigation, a wildlife biologist conducting habitat assessment, or an economic policy advisor modeling for financial stability, the geospatial approach provides a lens to illuminate and advance our diverse interests and goals.

We are excited to have you join us at this year’s GIS In Action conference. For our keynote, Sisinnio Concas, Ph.D., Program Director for the Center for Urban Transportation Research, will share his insights into autonomous and connected vehicles and how new data sources are critical to developing smarter cars and smarter roads. Through the conference’s diverse sessions, workshops, and socials, you will have opportunities to learn and share with your colleagues and make new professional connections.

GIS in Action is a collaborative effort between the Oregon and Southwest Washington chapter of URISA and the Columbia River Region chapter of the American Society for Photogrammetry and Remote Sensing (ASPRS). The value of the geospatial industry grows greater every year, and every year GIS In Action brings together talented, creative people to share what they’re working on. Let’s share our collective IQ, learn from one another, and build a stronger, more vibrant community. We look forward to meeting you!

Camille Westlake, President, ASPRS Columbia River Region
Molly Vogt, President, Oregon & SW Washington URISA

The conference takes place Monday, April 22nd and Tuesday, April 23rd in the 3rd floor ballroom at Smith Memorial Student Union on the Portland State University campus (1825 SW Broadway, Portland, OR 97201 ).

Identifying Impervious Surfaces within Open Spaces in the "100-year Flood Plains" in Oregon State
Jonathan Tissandier and Will Nolan, University of Washington
This project identifies impervious surfaces in the "100-year flood plains" in Oregon State using a process developed by the National Oceanic and Atmospheric Administration (NOAA) in Esri's ArcGIS Pro. NOAA's Office of Coastal Management (OCM) has developed a GIS workflow to facilitate Open Space Preservation (OSP) credit calculations. Under the Federal Emergency Management Agency (FEMA) Community Rating System (CRS) Activity 420, communities are given credit for activities that reduce development in flood plains, potentially lowering rates for National Flood Insurance Program (NFIP) policy holders in that community. Activity 420 OSP is one of the most credit rich CRS activities. This workflow consists of subtracting impervious surface areas from potential open space areas. In the past, National, satellite-derived impervious surface data were coarse. Our team will now derive more accurate areas from newly acquired one-foot imagery for Oregon using image processing within ArcGIS Pro. The image processing involves extracting color bands to distinguish features, segmenting the imagery and classifying by broad land-use types, and reclassification into either pervious or impervious surfaces. Not only do these methods contribute to specific flood-risk management activities such as the CRS, but they also serve as a foundation for other flood-risk identification and mitigation projects in other critical areas in Oregon state.
