Greetings GDAL Community, I've been working with GDAL lately, and I have a question for more experienced GDAL users or developers. GDAL has a dependency on PROJ. I know some GDAL functions, for example, will respond with an error message if the proj.db cannot be found, and there is a dependency on PROJ during the GDAL build. PROJ has a rather large collection of data packaged separately from the PROJ source code (described in PROJ-data readme as containing shift grids for horizontal and vertical coordinate transformations.). You can build both PROJ and GDAL without PROJ data, and the GDAL functions I've used (albeit I've only used a few) seem unaffected by not having PROJ data. Can any of you provide any insights into what the implications are of having PROJ data installed vs. not installed?
Thank you, Scott Arnold
