Tileset Builder

The Tileset Builder is a Fabric item that turns large geospatial files in your OneLake into fast, map-ready vector tilesets (PMTiles).

Large geometry datasets can be slow to draw directly. Building a tileset once lets Icon Map render millions of features smoothly at every zoom level.

What it takes and produces

• Input: a geospatial file from OneLake — .shp (Shapefile), .geojson, .geojsonl, or .gpkg (GeoPackage).
• Output: a PMTiles tileset plus a bounds dataset (Parquet) containing each feature's attributes and bounding box.

On demand or scheduled

You can run a build on demand, or put it on a schedule so the tileset is regenerated automatically as the source data changes. A run history lets you monitor builds, and the item integrates with Fabric's monitoring.

Using the result

Once built, add the tileset to a map as a Vector tiles layer, or publish it through your Organizational Catalog.

Next steps

• Imagery & tiles — add a vector-tile layer.
• Organizational Catalog — share the tileset as a catalog layer.
