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.

Changes
1.5.0 2012-12-05
Features:
read remove_before/refresh_before timestamp from file
add –concurrency option to mapproxy-utils export
Fixes:
fixed where option for coverages (renamed from ogr_where)
only write seed progess with –continue or –progress-file option
Other:
add EPSG:3857 to WMS default SRSs and remove UTM/GK
remove import error warning for shapely
create metadata table in MBTiles caches
1.5.0rc1 2012-11-19
Features:
clipping of tile request to polygon geometries in security API
WMTS support in security API
mixed_image mode that automatically chooses between PNG/JPEG
use caches as source for other caches
mapproxy-util grids tool to analyze grid configurations
mapproxy-util wms-capabilities tool
mapproxy-util export tool
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
Improvements:
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
Fixes:
fixed reloading of multiapps in threaded servers
fixed BBOX check for single tile requests
fixed TMS for caches with watermarks
fixed limited_to clipping for single layer requests with service-wide clipping geometries
fixed WMTS RESTful template
Other:
deprecated origin option for tile sources was removed
empty tiles are now returned as PNG even if requested as .jpeg
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
