Expose `RasterTileExtractor::reproject_to_webmercator` to Godot #18

Open kb173 opened 4 years ago

kb173 commented 4 years ago

The RasterTileExtractor offers a function to reproject any raster data into webmercator and save it on the disk, but it is not yet exposed to Godot. Now that RasterTileExtractor::clip does no on-the-fly reprojection for performance reasons, it would make sense to have access to reproject_to_webmercator. Thus, it can be used for an on-demand preprocessing step to get everything into the same projection.

the target projection should be flexible as we currently plan to use MGI Austria Lambert, but this could change regarding available geodata, region, purpose

We should consider adding a general reproject functionality. However, it needs to be well documented that it is not suitable for real-time use, as reprojecting can take minutes or perhaps even hours!
