I developed an open and free Geo API for Portugal and now I'd like to provide altitude without the need of external APIs, that is, using the GeoTIFF file provided by the government agency. I developed this API solely in Node.JS
Anyone with experience with GDAL lib for node can tell me how to get elevation from a GeoTIFF file? I have been checking other answers here with Python or Java but the methods/function names seem quite different.
