Do you have examples/numbers of this? GDAL uses PROJ for project/reproject, how can it be slower?
I’ve been in the GDAL and PROJ e-mail list for years and the amount of knowledge of the people working in those projects is immernse. The idea of abandoning them is something that does not make any sense to me. Specially GDAL. People really have an idea of the work put in reading the myriad of raster & vector formats that GDAL provides?
