Serverless Raster or Imagery Tile Serving using PMTiles
A few months ago, I created a video tutorial about how to serve raster or imagery tiles using Github using TMS/XYZ Tile Serving protocol. The tiles can be consumed by a web gis app either as a base map or operational layer. Although the workflow is proven to be working for general cases, the tiles displaying and loading speed are quite mediocre compared to API-based serving such as WMS, WMTS, or ArcGIS Services. Now, there is one protocol called PMTiles that can also provide similar functionality with additional features and better loading/displaying performance. PMTiles in many ways is similar to Mapbox MBTiles format (the tiles are packed into a single file), or ArcGIS's TPK Package. However, PMTiles can be served directly using a common HTTP query (not like MBtiles or TPK which must be deployed into API Services to be able to be consumed by a webgis client). So, if you want to use Github as your host, you won't find an uploading problem...
