Hello the experts
I searched the whole forum to see if anyone uses GDAL libraries... but couldn't find anyone. I got good help to use one of the programmes from the library to extract values for specific coordinates from a geotiff or other GIS format "images" through a console pipe to execute
gdallocationinfo -valonly -wgs84 weatherrasterfile 127.23 39.42
This works, but is terribly slow. When doing this operation inside a GIS (I use QGIS), it is lighting fast...
The GDAL website has a lot of downloadable stuff for Debian and Ubuntu (I use Mint)
https://packages.debian.org/cgi-bin/sea ... elease=all
and QGIS has installed a number of "gdal libraries" that come by the names gdal-bin, libgdal1, libgdal20. I assume it should be possible to use those rather than downloading other ones.
Questions... if someone knows or has some time
(1) how can one know what's "inside" a library
(2) how do I tell my FB programme?
(3) how do I call the functions inside the library
Many thanks if someone can help...

You have to translate the C-API headers *.h to FreeBASIC include files *.bi
