crss

A table of commonly-used coordinate reference systems, their nicknames, and WKT2 (well-known text) strings

projection

coordinate

Implements species distribution modeling and ecological niche
modeling, including: bias correction, spatial cross-validation, model
evaluation, raster interpolation, biotic "velocity" (speed and
direction of movement of a "mass" represented by a raster), interpolating
across a time series of rasters, and use of spatially imprecise records.
The heart of the package is a set of "training" functions which
automatically optimize model complexity based number of available
occurrences. These algorithms include MaxEnt, MaxNet, boosted regression
trees/gradient boosting machines, generalized additive models,
generalized linear models, natural splines, and random forests. To enhance
interoperability with other modeling packages, no new classes are created.
The package works with 'PROJ6' geodetic objects and coordinate reference
systems.

crss function

An object of class <code>data.frame</code>. This is a table with "named" coordinate referenbce systems and their well-known-text (WKT2) representation. It can be used as-is, or with <code>getCRS</code> to quickly get a WKT for a particular CRS. The fields are as:<ul>
<li><code>long</code>: "Long" name of the CRS</li>
<li><code>short1</code> and <code>short2</code>: "Short" names of the CRS</li>
<li><code>region</code>: Region for which CRS is fit</li>
<li><code>projected</code>: Is the CRS projected or not?</li>
<li><code>projectionGeometry</code>: Type of projection (<code>NA</code>, 'cylindrical', 'conic', or 'planar')</li>
<li><code>datum</code>: Datum</li>
<li><code>type</code>: Either 'CRS' or 'data'. The former are proper CRSs, and the latter are those used by popular datasets.</li>
<li><code>wkt2</code>: WKT2 string.</li>
<li><code>notes</code>: Notes.</li>
</ul>
