Hello
I want to implement a vector mbtile viewer and am considering using gdal to extract the data. I am wondering if gdal public API allows to : - Retrieve metadata such as : o the min and max zoom levels for each layer o the min and max tile indexes for each layer and zoom level - Extract efficiently all the features of a given tile (with specific x/y indexes) at a given zoom level I am currently reading the MBTILES implementation source code (mbtilesdataset.cpp) and there seems to be quite a lot of tricks internally (for instance with SetSpatialFilter) Would somebody have an example using gdal to extract efficiently a tile for a given layer, given tile index and given zoom ? Regards Christophe
