What is the Nova Scotia Topographic Database (NSTDB)?
The NSTDB is the base map foundation for the Province. It is comprised of the Resource Series / 1:10,000 scale (contains all topographic features incl. contours and DEMs, features are generalized or symbolized to be represented at this scale (i.e. small building are shown as symbols, roads are single line features), complete digital mapping coverage for the province is available; and, Large Scale Series / 1:5000, 1:2000, and 1:1000 (contains mapping coverage for cities, towns, and areas of special interest – corridor mapping for proposed Highways (DOT), airports). More detailed data is collected and less features are generalized or symbolized.(i.e. building footprints are plotted to scale, both sides of the road shoulder are portrayed, fences and individual trees are shown). • Where does the NSTDB data come from? Most topographic data is collected from aerial photography and more and more data is being collected from source providers. The Resource 1:10 000 mapping is sourced from 1:40
