An accelerating proxy for web map services
Project description
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.

The documentation is available at: http://mapproxy.org/docs/latest/
Changes
1.4.0 2012-05-15
Fixes:
fix TypeError exception when auth callback returns {authorized:’full’}
use MAPPROXY_LIB_PATH on platforms other that win32 and darwin
raise config error for mapnik sources when mapnik could not be imported
1.4.0rc1 2012-05-02
Features:
support clipping of requests to polygon geometries in security API
support for WMS 1.3.0 extended layer capabilities
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
the debug source does not overwrite the layer extent anymore. makes it more usable in demo/wms clients
support for multiple files and recursion in base option
mapproxy-seed ETA output is now more responsive to changes in seed speed
improved demo service - choose different SRS for WMS layers - support for WMTS
Fixes:
support loading of WKT polygon files with UTF8 encoding and BOM header
upgraded dictspec module with fix for some nested configuration specs. a bug prevented checking of the layers configuration
Other:
the documentation now contains a tutorial
old layer configuration syntax is now deprecated
EPSG:4326/900913/3857 are now always initialized with the +over proj4 option to prevent distortions at the dateline see: http://fwarmerdam.blogspot.de/2010/02/world-mapping.html
1.3.0 2012-01-13
No changes since 1.3.0b1
1.3.0b1 2012-01-03
Features:
support for RESTful WMTS requests with custom URL templates
support for CouchDB as tile backend
support for Mapnik 2 sources
limit maximum WMS response size with max_output_pixels
new color option for watermarks
new mapproxy-util serve-multiapp-develop command
new wms.bbox_srs option for bounding boxes in multiple SRS in WMS capabilities
Improvements:
log exceptions when returning internal errors (500)
Fixes:
fix BBOX in WMS-C capabilities
prevent exception for WMS requests with unsupported image formats with mime-type options (like ‘image/png; mode=24bit’)
fixed blank image results for servers that call .close() on the response (like gunicorn)
Other:
origin option for tile sources is deprecated. use a custom grid with the appropriate origin.
1.2.1 2011-09-01
Fixes:
fixed configuration of watermarks
support for unicode title in old-style layer configuration
1.2.0 2011-08-31
Fixes:
fixed links in demo service when running as MultiMapProxy
1.2.0b1 2011-08-17
Features:
support for MBTiles cache
support for (tagged-) layers for Mapnik sources
configurable cache layout (tilecache/TMS)
new mapproxy-util scales tool
use MultiMapProxy with server scripts (mapproxy.multiapp.make_wsgi_app)
Fixes:
prevent black borders for some custom grid configurations
all fixes from 1.1.x
