TiSrv is a tile server that try to implement OGC API – Tiles, currently only vector tile is supported.
The following OGC API – Tiles comformance classes are implemented: Core, TileSet, TileSets List, Geo Data Resource Tilesets.
TiSrv is built on top of these software: FastAPI, morecantile, asyncpg. And special thanks to pg_tileserv for its excellent SQL template.
Unix like environment:
git clone https://github.com/kikitte/tisrv.git tisrv
# change working directory
cd tisrv
# preparing virtual env
python -m venv venv
source venv/bin/activate
# install dependencies
pip install -r requirements.txt
# start server, Note: before you starting the server, the configuration file may be edited.
uvicorn tisrv.main:appThe configuration file is tisrv.conf, and it should be placed in the root of working directory. Please check tisrv.conf for more detail about configuration.
Clients that flows the OGC API – Tiles should play well with this service, for example tileset endpoint can be used by openlayers, see OpenLayers - OGC Vector Tiles.
Vector Tile:
- A geospatial data resource represents a spatial table in database.
- A dataset represents a scheme in database.
