Canada VMap1

VMap1 is a vector digital topographic reference product developed by Natural Resources Canada (NRCan) and the Department of National Defence (DND), complying with international military specifications for vector map, level 1. There are 24 VMap1 libraries covering the Canadian territory. The National Topographic Data Base (NTDB) at a scale of 1:250,000 is the main source used to populate the Canadian VMap1 libraries. Administrative boundaries from Statistics Canada are used to add international borders, provincial limits, and Indian reserve limits. NRCan paper maps at 1:250,000 scale and the Canadian Geographical Names Data Base (CGNDB) were used to capture names. JOG (Joint Operations Graphic) paper maps were used by DND for the production of libraries 37, 38, and 66. This collection comprises 1,258 Shapefile layers spanning VMap1 libraries covering the Canadian territory, representing thematic layers across landforms, hydrography, transportation, vegetation, boundaries, populated places, and infrastructure. Feature types include point, line, and polygon geometries. VMap1 is published once and no product revision is planned. The data reflects information compiled primarily from the NTDB with source dates ranging from 1945 to 1996. The format for data included with this record is predominantly point data, but also consists of polygon and line data as well.
