An agreement has been established between Communications Canada and Natural Resources Canada, in collaboration with the Association of Canadian Map Libraries and Archives, to provide national digital topographic data at no cost through the Depository Services Program. The National Topographic Database (NTDB) includes over 10,000 files covering all of Canada, featuring scales of 1:50,000 and 1:250,000. Acadia University participates in partnerships with DMTI Spatial Inc. and Statistics Canada’s Data Liberation Initiative, granting affordable access to GIS data, software, and valuable resources for research and teaching.

  1. GIS Data @ Acadia

  2. Products • National Topographic Database (NTDB) • DMTI Spatial Inc. • Statistics Canada (Geography Division) • Nova Scotia Topographic Database (NSTB)?

  3. National Topographic Database (NTDB) The Deal: An agreement has been reached between; Communications Canada AND Natural Resources Canada In collaboration with; The Association of Canadian Map Libraries and Archives, and Canadian Association of Research Libraries,  to make national digital topographic data developed by Geomatics Canada available through the Depository Services Program at NO COST

  4. National Topographic Database (NTDB) Value Approx. 10,000 files All of Canada (7209 files) at 1:50,000 scale = $1 275 533.95. All of Canada (1169 files) at 1:250,000 scale = $232 845.28.

  5. National Topographic Database (NTDB) Coverage: National Currency: Quarterly, semi-annual, or annual maintenance available Scale: 1:50 000 and 1:250 000 Datum (Projection): UTM or NAD83 Formats: ESRI Shapefile, ESRI ArcInfo, DXF, MID/MIF, GIF, CCOGIF

  6. National Topographic Database (NTDB) • Themes • Covers the entire Canadian landmass and includes natural and artificial features, such as: • Hydrography • Vegetation • Roads • Infrastructures • Administrative boundaries • Landforms • Relief • Hypsography(contours)

  7. Canadian Digital Elevation Data (CDED) • Ground elevations at regularly spaced intervals • Points and Vertices are according to UTM and NAD83 projection • Scale = 1:250,000

  8. CDED and National Topographic Database (NTDB) Available under license to faculty, students and staff for research or teaching purposes only.

  9. DMTI Spatial Inc. • Acadia’s recent participation in the academic DMTI Spatial Consortium, provides DMTI spatial files and software to Data Liberation Initiative (DLI) participants. • This academic partnership between DMTI Spatial Inc. and a large consortium of university libraries has provided Acadia access to Geocoding software and valuable GIS data, including detailed street network files for small Canadian geographic areas.

  10. Statistics Canada’s Data Liberation Initiative • Acadia’s participation in the Statistics Canada Data Liberation • Initiative (DLI) provides Acadia affordable access to Statistics Canada data files and databases, including GIS data and software. • GIS data includes boundary files and street networks, health • regions. • Most numeric data, e.g. the Census, health indicators, includes • a geographical component which makes it possible to visualize • this data using a GIS.
