I have a shapefile with a .prj file I've never seen before. In fact, it seems that GDAL doesn't even know what it is (see below).
Therefore, when I read it into R with
raster::shapefile() the CRS isn't set. When I set it to the closest thing I can find (ESRI:54030, or ESRI:53030), the projection is still off (even when I modify the Central Meridian with "+lon_0=11" in the proj4string).
Here's the WKT:
(base) Richs-MacBook-Pro:whymapdata_world richpauloo$ gdalsrsinfo wrb11hyg_7d84d.prj ERROR 6: No translation for Robinson_ARC_INFO to PROJ.4 format is known. PROJ.4 : OGC WKT : PROJCS["WGS_1984_Robinson_ARC_INFO", GEOGCS["GCS_WGS_1984", DATUM["WGS_1984", SPHEROID["WGS_84",6378137.0,298.257223563]], PRIMEM["Greenwich",0.0], UNIT["Degree",0.0174532925199433]], PROJECTION["Robinson_ARC_INFO"], PARAMETER["False_Easting",0.0], PARAMETER["False_Northing",0.0], PARAMETER["Central_Meridian",11.0], UNIT["Meter",1.0]]
If I compare this to the WTK for ESRI:54030 and ESRI:53030 they're clearly not the same.
What projection do I have? How can I set the projection for this object in R for either an sp or sf object? Do I need to write a custom proj4 string from this WKT?
