MapProxy 1.7.0

An accelerating proxy for web map services

MapProxy is an open source proxy for geospatial data. It caches, accelerates and transforms data from existing map services and serves any desktop or web GIS client.

MapProxy is a tile cache, but also offers many new and innovative features like full support for WMS clients.

MapProxy is actively developed and supported by Omniscale, it is released under the Apache Software License 2.0, runs on Unix/Linux and Windows and is easy to install and to configure.

• on_error handling for tile sources. fallback to empty/transparent tiles when the source returns HTTP codes like 404 or 204

• add HTTP Cache-Control header to WMS-C responses

Improvements:

• WMS source requests and requests to cached tiles are now clipped to the extent. this should prevent projection errors when requesting large bbox (e.g. over 180/90 in EPSG:4326)

• improved lock timeouts in mapproxy-seed
