Title: NSTDB_10000_P
Abstract: The Nova Scotia Topographic Database (NSTDB) consists of the following data: topographic, contours, and a Digital Elevation Model (DEM). Topographic information is commonly referred to as the map base; this is a 3D dataset, which includes the following nine standard feature code groupings: buildings, designated areas, delimiters, roads & railroads, land cover, hypsography, structures, utilities, and hydrography. Contours display the characteristics of the terrain relief. The contour interval varies depending on the mapping scale. For example, 1:2,000 scale mapping has a contour interval of 2 metres and 1:10,000 mapping has a contour interval of 5 metres. The DEM is an ASCII point file which contains x, y, and z coordinate data. Each window contains data collected every 2mm at the aerial photography scale. This results in 20 metre or 36 metre spacing for 1:2,000 mapping, 36 metre spacing for 1:5000 mapping, and 80 metre spacing for 1:10,000 mapping. For terrain modelling applications, the DEM file should be used along with the corresponding 3D topographic breakline features in the topographic file.
