High Resolution Change Detection (HRCD) data shows changes in land cover over time – specifically new development and/or tree loss in an area.  We use high resolution imagery (1-meter) from the U.S. Department of Agriculture to extract information about changes in land cover for areas across Washington. This includes polygons which show the locations of change and attribute tables with details about causes (Change Agents) and types of changes observed (e.g. canopy loss, impervious surface gain).
