The topographic layer contains contour intervals at five feet or less for the entire database. Additionally, selected spot elevations are stored as points. Topographic data is compiled directly from the aerial photography and is stored in a layer which contains both arc and point attributes.The Topography Layer has no related data files. All attributes are stored directly in the Arc Attribute Table (AAT) and the Point Attribute Table (PAT). The layer name is TPGMN and TPGMN.AAT and TPGMN.PAT are the Arc Attribute Table and the Point Attribute Table, respectively. |
