Thank you very much, I have put the files proj.db, proj.ini and proj.exe together with the dll proj_9_1.dll this solved the problem when I use gdal executables like gdalwarp.exe and also I have added OSRSetPROJSearchPaths(), when I use the gdal API, and it works correctly for me in all cases, so it seems that the path of the proj.db file in an environment variable was not enough.
Thank you very much and regards ________________________________ Elena Ruiz [https://www.aplitop.com/descargas/logo.png] Sofware Development & Technical Support Tel.: +34 952 43 97 71 er...@aplitop.com www.aplitop.com <http://www.aplitop.com/Product/es/6/5/tcptunnel> <http://www.aplitop.com/New/es/281/mdt-75-a-la-venta> De: Chris Smemoe <csme...@aquaveo.com> Enviado el: jueves, 30 de marzo de 2023 19:21 Para: Elena Ruiz <er...@aplitop.com>; gdal-dev@lists.osgeo.org Asunto: RE: [gdal-dev] Cannot find proj.db Elena, I have had this same problem. We have a few methods of setting the location of the proj.db file. When we call from C++ (or from python), there's a function called OSRSetPROJSearchPaths that's handy. If you're calling from a command line, you could try setting your environment variable just before calling your function (set "PROJ_LIB=c:\path\to\proj\"). I think there's also a command line option to set your PROJ_LIB. You could try adding "--config PROJ_LIB "c:\path\to\proj"" to your command line and see what that does. I haven't personally tried it. I haven't had to do these things as much with the python/conda distributions of the commandline programs for whatever reason.

Is there another way to set the PROJ_LIB path besides adding an environment variable? Is there any way to know where the PROJ_LIB is looking for my version of GDAL?
