rcanvec (version 0.2.1)

Access and Plot CanVec and CanVec+ Data for Rapid Basemap Creation in Canada

Description

Provides an interface to the National Topographic System (NTS), which is the way in which a number of freely available Canadian datasets are organized. CanVec and CanVec+ datasets, which include all data used to create Canadian topographic maps, are two such datasets that are useful in creating vector-based maps for locations across Canada. This packages searches CanVec data by location, plots it using pretty defaults, and exports it to human- readable shapefiles for use in another GIS.
