<DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN><SPAN>Landcover and active transportation amenities in eastern Pima County were extracted as polygons and classified via AI by Ecopia Tech Corp for Pima Association of Governments from PAG's November 2023 orthos at 15 cm resolution. The data covers a 1,400 square mile extent of urban Eastern Pima County, ie the greater Tucson metro area. Data was released in spring of 2025 after a QAQC process by subject matter experts in the region. Data includes 2D Vector wall-to-wall polygons representing land cover, 3D vector, and transportation-related linework. The data is intended for use to fill in data gaps in local infrastructure inventories and thereafter, a gap assessment in infrastructure. Geometries include but are not limited to vector data for sidewalks, bike lanes, medians, driveways, edge of pavements, building footprints, grass, pervious areas, parking lots, tree canopy, vegetation, through lanes, and turning lanes, along with width attributes. 3D data includes buildings, bridges, and trees. </SPAN></SPAN></P><P><SPAN>Attributes in the 3d bridge feature class:</SPAN></P><P><SPAN>(1) CateTitle: Category of the polygon. </SPAN></P><P><SPAN>(2) med_height: median height above global average orthometric height(datum: NAD83). Height value is expressed in feet. </SPAN></P><P><SPAN>(3) rel_height: median relative height above ground. Height value is expressed in feet. </SPAN></P><P><SPAN>(4) guess: 1 means no confidence; 0 means confidence.</SPAN></P><P><SPAN /></P></DIV></DIV></DIV> |
