Hi, I was working with gdal 2.1.0, I was trying to convert a geopackage raster to mbtiles, I used GDALCreateCopy to convert the dataset to mbtiles.
On http://www.gdal.org/frmt_mbtiles.html I saw an example to use gdal_translate and then to use gdaladdo to overviews Q1: I got only one level of zoom level in the mbtiles. Is there any creation option to say to generate mbtiles from a to b zooms ? or I have to do by build overviews ??? Q2: I tried to convert the Geopackage ERDC_Whitehorse_GeoPackage.gpkg size 111 MB in Web Mercator EPSG:3857 from the url http://www.geopackage.org/#sampledata (GeoPackage contains a raster tile pyramid that was created with free imagery obtained from Geomatics Yukon and covers an approximately 30 square-kilometer area centered on the City of Whitehorse. It uses the Web Mercator (EPSG:3857) coordinate reference system, 256x256 pixel tiles, contains zoom levels 11-18, and is 110.8MB in size) *The resulting mbtiles was to 621MB Is this due to default PNG zlevel settings or any thing can be done on this ?* Thanks Gane
