This data represents structure footprints in Skamania County, Washington. It's purpose is for general mapping of manmade structures. Features were manually digitized using many years of available orthophoto imagery, and Lidar. While the dataset name indicates that features are 'footprints', it should be noted that buildings digitized on aerial photos are usually visible roof area, rather than a foundation 'footprint'. The dataset was originally developed in approximately 2017. Updates using newer aerial photos may occur as time allows, but the dataset is not necessarily 'current'.
