One of <code>nts.SCALESERIES</code>, <code>nts.SCALE250K</code>, or <code>nts.SCALE50K</code>

atscale


Retreive a list of NTS references at a given scale by bounding box.
Bounding box is in the form returned by <code>sp::bbox()</code>. NTS References
all have a valid series component (e.g. "021"), but map area (e.g. "H")
and map sheet (e.g. "01") are not checked to make sure they exist.


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.
