Combine MBTiles of Mapbox Vector Tiles.
Mortar was designed to combine multiple MBTiles produced by TippeCanoe into a single MBTiles file.
2 use cases for combining MBTiles were considered:
- Source data split into arbitrary polygons, resulting in multiple tile sets that each have the same layer, and tiles on the edges of each set need to be merged.
- Multiple data sets covering the same area, resulting in multiple tile sets that have different layers, but cover the same area.
