How to Convert KML to MBTiles: A Complete Guide
If you work with geospatial data, you’ve likely encountered KML (Keyhole Markup Language) – the standard format for Google Earth, and MBTiles – a highly efficient SQLite database format for serving vector or raster map tiles.
Converting a KML (vector points, lines, or polygons) into an MBTiles file is not a direct "file conversion" (like DOC to PDF). Instead, it is a two-step rendering process: convert kml to mbtiles
- Convert KML → GeoJSON (optional but recommended).
- Convert GeoJSON → MBTiles (raster tiles).
Below is the most reliable, open-source method using GDAL and tippecanoe (for vector MBTiles) or gdal2tiles (for raster MBTiles). How to Convert KML to MBTiles: A Complete
3. Vector tile generation (Mapbox vector tile spec)
tile_index = geojsonvt(geojson_data, max_zoom=14) Convert KML → GeoJSON (optional but recommended)
1. The "Infinite Tiling" Trap
Problem: You set Zoom 0 to Zoom 18. The math is exponential. A global map at zoom 18 requires over 68 billion tiles.
Fix: Calculate your area. For a city map, Zoom 14 (max) is fine. For a single building site, Zoom 20 is fine. Use the QGIS Zoom to Layer button to see your extent, then guess the max zoom.
Method 2: The Command Line Way (Mapbox Tippecanoe)
For developers and power users, Tippecanoe (created by Mapbox) is the industry standard for creating vector MBTiles. It is incredibly fast and handles massive datasets efficiently.
