spex-package: spex

In mdsumner/spex: Spatial Extent Tools

Description

Tools for spatial extents that are agnostic regarding format (i.e. sp, sf, or raster). These functions fill some of the gaps within and between these packages for dealing with object extents in flexible ways. Generally, spex considers extents of raster cells, and extents of objects as first-class objects (with projection metadata). and provides helpers for latitudinal boundaries within projected data.

Spatial Extent

buffer_extent	Buffer an extent to a given whole number.
latitudecircle	Create a latitude circle in a chosen projection.
latmask	Mask a raster based on a minimum (or maximum) latitude.
polygonize	Convert raster cells to polygons.
qm_rasterToPolygons	The sf version of polygonize.
qm_rasterToPolygons_sp	The sp version of polygonize.
spex	A function to produce a fully fledged Spatial object extent.
xlim, ylim	Helper functions for extents.
