Environmental Data Environmental data refer to regulated environmental features. The database includes two natural features, elevation and hydrography. Elevation - elevation matrix, or a regularly spaced grid of locations with elevation values, will comprise the database. Hydrography will be subdivided into two layers, stream, and shore. Linear surface water features comprise the streams coverage.
Shores are polygonal features for any body of standing water, such as lakes or ponds.
Any standing body of water that is connected to a linear feature will be represented in the streams coverage as a line. Utility Data - Data layers include water lines, sewer lines, storm water drainage system, and gas pipelines. Provides the proper number and pattern of control points for each stereo model in order to orient the stereo model to the ground for accurate digital photgrammetric compilation. Cadastre This is a physical cadastre based upon parcel boundary data provided by Consortium members, and not a legal cadastre. Cadastral Data show the location of all recorded boundaries and ownership.
