Description: <DIV STYLE="text-align:Left;font-size:12pt"><DIV><P><SPAN>This dataset includes changes in land cover throughout Washington State, specifically areas of tree loss and development. Changes are represented as polygons and include qualitative descriptions and quantitative assessments of changes. Attributes provide details about causes of change (Change Agents), types of changes observed (e.g. canopy loss, impervious surface gain), area of change, and time period for when the change occurred. The change locations were identified from analyzing high resolution (1-meter) NAIP imagery, allowing changes as small as a single tree or new home to be identified. This dataset covers most of Western Washington and several counties in Eastern Washington. Coverage is split along county and/or WRIA boundaries and the time periods for change locations vary by county and/or WRIA. All areas in the dataset were assessed for changes between 2011 and 2017; additionally, some locations include changes as early as 2006 or as recent as 2019. Visit https://hrcd-wdfw.hub.arcgis.com/ or email HRCD@dfw.wa.gov for more information on how the data is created, accuracy information, tutorials, user guides, and current coverage information.This dataset is updated regularly (about twice a year) with more recent years of change, new counties / WRIAs, or both. This copy of the data was updated in December 2021. </SPAN></P></DIV></DIV>
