I have a few rasters (CRS 32632) and a shapefile with the coordinates of points that I need to study (CRS 2154). I need to crop my rasters with the shape to only keep the area where my points are, but therefore I need to reproject the shapefile in CRS 32632.
Here's my code
data <- st_read("inventory.shp")
st_transform (data, 32632)
This gives me the following error :
Warning message:
In showSRID(uprojargs, format = "PROJ", multiline = "NO") :
Discarded datum Unknown based on GRS80 ellipsoid in CRS definition,
but +towgs84= values preserved
Does anyone have a clue about how I could settle this?
