This data folder holds various file formats that can be read and served by SpatialServer. The formats include:

• .PBF .mbtiles files (Mapnik Vector Tile)
• .PNG .mbtiles files (PNG caches exported from TileMill for example)
• .SHP files (ESRI Shapefile Format)
• In-Memory Shapefiles - ESRI Shapefiles that you want to be loaded into memory (as opposed to reading the shapefile on every tile request)
• Rasters - GeoTIFF files may be placed in the rasters folder in order to be served. (This is not really functional yet)
