New features

Some noteworthy improvements since 1.4.0 are:

Clipping WMTS/TMS/KML requests to polygons

The security API now also supports limiting requests to polygon geometries for all tile services.


Mixed image mode

The mixed image mode automatically chooses between PNG and JPEG format depending if the image has transparency or not. This is a great feature for aerial images with transparency at the image boundaries. Thanks to Thomas Bonfort for the idea.


Caches as source for other caches

You can now use a cache as a source for another cache. You can use this to directly reproject tiles or to make changes to your grid configuration without losing your existing cache.

Changed default SRS in WMS

The WMS now supports EPSG:3857, the official EPSG code of the Webmercator projection (EPSG:900913). UTM 32/33N and Gauß-Krüger zones 3-5 were removed from the default list, since they are only usable in parts of Europe. Make sure you've configured all SRS you are using in the service configuration.

New tools

There are three new tools:

  • mapproxy-util grids: debug and analyze grid configuration
  • mapproxy-util wms-capabilities: get bbox and min/max_scales of existing WMS
  • mapproxy-util export: export (parts) of your cache to MBTiles or a TMS directory


Other features

  • use_grid_names option to access Tiles/TMS/KML layers by grid name instead of EPSGXXXX
  • origin option for TMS to change default origin of the /tiles service
  • continue stopped/interrupted seed processes
  • support min_res/max_res for tile sources


  • do not show layers with incompatible grids in WMTS/TMS demo
  • make 0/0/0.kml optional for the initial KML file
  • use BBOX of coverage for capabilities in seed_only layers
  • ignore debug layer when loading tile layers
  • simplified coverage configuration
  • add reloader option to make_wsgi_app()
  • add MetadataURL to WMS 1.1.1 capabilities
  • improved WMTS services with custom grids (origin)
  • use in_image exceptions in WMS demo client
  • larger map in demo client
  • always request with transparent=true in WMS demo client
  • use in_image exceptions in WMS demo client
