In paleolimbot/rcanvec: Access and Plot CanVec and CanVec+ Data for Rapid Basemap Creation in Canada

Description

Generate NTS strings from NTS references or other arguments to generate such a list from nts() based on arguments provided.

Usage

ntsstring(ntsid = NULL, lat = NULL, lon = NULL, bbox = NULL,
  atscale = nts.SCALE50K)

Arguments

ntsid	An arbitrary number of NTS references in the form c("021", "H", "01") or list(c("021", "H", "01"), c("021", "A", "16")) to be converted
lat	A vector of latitude values
lon	A vector of longitude values
bbox	A bounding box in the form returned by sp::bbox()
atscale	An integer value describing scale, either 1 (250k) or 2 (50k)

Value

a character vector of NTS reference strings in the form "021H01".

Examples

ntsstring(c("021", "H", "01"))

library(prettymapr)
ntsstring(bbox=makebbox(45.125, -64.25, 44.875, -64.75))
