7-Years of Puget Sound Change Detection and the upcoming Geospatial Land Activities Dataservice
Presentation Abstract
The WA Dept. of Fish and Wildlife has been mapping land cover change under the High Resolution Change Detection (HRCD) banner throughout Puget Sound since 2006. We are currently completing the third time period making change data available for 2006-2009, 2009-2011 and 2011-2013. The latest imagery acquisition in 2015 is currently being preprocessed for analysis. Mapped change is predominately urbanization and forestry activities, with no mapped instances of restoration or newly created habitat. As such change detection has a dark side, lacking the ability to evaluate the habitat balance sheet of losses to gains. Change detection also only maps land cover as initial land-cover on identified change locations. In this presentation I will talk about the third round of change data and show preliminary work on mapping land cover using high resolution data for the majority of the non-federal lands in Puget Sound. In addition, we are attempting to bolster the light side by creating the GLAD data service to spatially map restoration sites and other habitat improvement work. While several restoration data stores exist on the web, none have comprehensive spatial data for assessing areas of impact. The GLAD project will be revisiting recent existing restoration projects to acquire spatial data and streamlining an input system to capture spatial data going forward. The combination of change, land cover and restoration data should help provide a more balanced picture of progress towards the terrestrial portion of Puget Sound recovery.
