At first glance, the request to "convert KML to MBTiles" seems like a cartographic paradox. KML (Keyhole Markup Language) is an XML-based format for describing vector features—points, lines, polygons, and 3D models. MBTiles, on the other hand, is a SQLite database containing millions of pre-rendered raster image tiles (or, in modern extensions, vector tiles).
You cannot simply change a file extension from .kml to .mbtiles. Instead, the conversion is a process: you are taking the geographic data contained in a KML file and rasterizing it into a zoomable tile pyramid.
Why would you want to do this?
In this article, we will explore every method to achieve this conversion, from GUI tools to command-line scripts, and discuss the crucial difference between raster and vector MBTiles. convert kml to mbtiles
Best when you want vector tiles (small, scale-independent, client-styled).
Prerequisites:
Steps:
(Optional) Simplify/clean or split large files into tilesets per feature type.
Generate MBTiles with tippecanoe:
tippecanoe -o output.mbtiles -Z 0 -z 14 --drop-densest-as-needed --extend-zooms-if-still-dropping input.geojson
Recommended flags:
Validate:
Notes:
ogr2ogr -f GeoJSON data.geojson input.kml
tippecanoe -o output.mbtiles -Z0 -z14 --drop-densest-as-needed data.geojson
