Overview

About

Functions to produce a fully fledged 'geo-spatial' object extent as a 'SpatialPolygonsDataFrame'. Also included are functions to generate polygons from raster data using 'quadmesh' techniques, a round number buffered extent, and general spatial-extent and 'raster-like' extent helpers missing from the originating packages. Some latitude-based tools for polar maps are included.

Changes in 0.7.1
  • Fixed tests.
  • Added sfc method, and now using crsmeta.
  • Ensure projargs is character, not logical.
