oce map projections available in PROJ6
Jan 16, 2020 oce · map · R
This blog posting tests whether the projections used in a previous posting about oce will work with the `sf` scheme.

Introduction

The goal is to test the existing oce projections, and also the new proj projections. The latter are recovered by typing the following in a unix console.

1

proj -l       # list names of all projections

but note that a handfull are actually transformations, not projections, and they are not tested here.

It is possible to get more information on any given projection with e.g.

1

proj -l=ccon  # list info on ccon

Overlap

These functions are in oce, but not in proj: longlat, latlong.

These functions are in proj, but not in oce: affine, airy, alsk, apian, august, bacon, bertin, boggs, calcofi, cart, ccon, chamb, comill, denoy, eqearth, eqdc, geoc, geogoffset, gins, gs, gs, hammer, helmert, imw_p, isea, krovak, labrd, lagrng, larr, lask, lonlat, latlon, lcca, lee_os, lsat, misrsom, nicol, nzmg, noop, ortel, patterson, pop, push, rpoly, somerc, gstmerc, tcc, times, tobmerc, webmerc.
