I'm running a fresh R installation with RStudio. Installed packages are:
library(randomForest) library(randomForestExplainer) library(raster) library(rgdal) library(sf)
When I try loading any raster with South America Albers Equal Area Conic projection (ESPG: 102033) I receive the following warning:
Warning message: In showSRID(uprojargs, format = "PROJ", multiline = "NO", prefer_proj = prefer_proj) : Discarded datum Unknown based on Australian Natl & S. Amer. 1969 ellipsoid in Proj4 definition
Keeping the projection is important to me, cause I need to be able to collect point samples from that raster and I need to make sure the points and rasters are projected in the same coordinate system. Albers seems to be the most accurate for my study area.
I have packages updated to the last version availble @ cran and I cannot seem to find a solution for this.
Projection details are (quoting QGIS 3.4.4 defs):
Extent: Extent not known Proj4: +proj=aea +lat_1=-5 +lat_2=-42 +lat_0=-32 +lon_0=-60 +x_0=0 +y_0=0 +ellps=aust_SA +units=m +no_defs
I need a way to import rasters with albers projections without having them discarded.
