The proxy=FALSE is needed otherwise when converting with as(.,'Raster') the output reverts back to the 20166662x23418224 dimension of the full global level 17 zoom raster. Options=c('USE_BOUNDS=NO','ZOOM_LEVEL=17'), proxy=FALSE) Use the stars package which does allow you to pass GDAL options: s = stars::read_stars('04010588800801.mbtiles', As you go out you lose detail, and below level 13 you just get the overview maps.Ī slightly more direct way to read from the. The other zoom levels might be useful to you so convert them using the gdal_translate procedure above.

If this is what you want then I strongly suggest you try and get vector data from the supplier and not have to do all this! Remember this is only raster image data so if you want the coordinates of those points you'll have to create a new layer in QGIS and manually create a point data set over the imagery. Here's an extreme zoom into level 17 in QGIS showing the limits of the resolution: Note this is quite a high resolution image so you can't read the labels, but if you zoom in (or load into QGIS and interact there) you can read the labels. Reading and then plotting this level 17 RGB image can then be done: > z17 = raster::stack('z17.tiff') This I can do with gdal_translate on the command line or via the gdalUtils package to create a GeoTIFF for a given zoom level, using USE_BOUNDS=NO to constrain the output to only where tiles exist:Ĭommand line: gdal_translate -oo ZOOM_LEVEL=17 -oo USE_BOUNDS=NO 04010588800801.mbtiles zoom17.tiff We could load this into R, but that size is enormous and I can't find a way to select a given zoom level and a given range based on the valid tiles. Gdalinfo shows a few things about the mbtiles file: $ gdalinfo 04010588800801.mbtiles First convert the tpk file to mbtiles using the tpk conversion utilityįrom tpk export mbtiles 04010588800801.tpk 04010588800801.mbtiles
