luftj / slippy-tif

a simple webserver for viewing geotiffs and serving them as XYZ tiles

slippy-tif

Simple slippy tiles web viewer for raster geodata files.

Installation

Requires

• python3 (tested with 3.9)
• flask
• GDAL
• GDAL python bindings

Usage

put vector maps (currently only geojson) into static/vector_maps/

add paths to georeferenced raster data to config.json

run $ python processing.py to convert raster data to tiles

run web server with $ python api.py (test server only)

for a production server see e.g. here.

dev

To do

• better way to get gdal path
• handle feature types for vector maps
• different styles for vector maps
• config.py automatically reload on change
• read layer extent from files
• inherit layer/group templates to simplify mapview template
• process tiles beginning from low zoom level -> does this even work? base tiles vs overview tiles
• process tiles continuously in the background
• dockerfile

Notes

• tiling the empty space of VRTs takes a lot of time -> processing them separately is faster for sparse data
