MapProxy¶

Proxy WMS & tile services¶

MapProxy speeds up mapping applications by pre-rendering and integrating maps from multiple sources and storing in a local cache. Layers can be made transparent, projections can be changed, multiple map layers can be transformed into one, watermarks can be added, and more…

MapProxy is flexible and scales from simple to complex use-cases: from a single tile cache for an OpenLayers web client to a central SDI node that combines, unifies and accelerates dozens of distributed WMS services.

MapProxy is used for the German broadband atlas to deliver maps for thousands of users and the German Federal Agency for Cartography an Geodesy uses MapProxy to aggregate WMS services from all 16 states on the fly.

Core Features¶

Input sources:

WMS 1.0.0–1.3.0 (MapServer, GeoServer, etc.)
TMS, WMTS (TileCache, GeoWebcache, etc.)
Mapserver and Mapnik (directly, without WMS)
any TileCache, Google Maps or Bing compatible source

Services:

WMS (1.0.0-1.3.0)
TMS
WMTS
KML SuperOverlays

Tile cache:

stores identical images just once (e.g. ocean tiles)
stores tiles in filesystem, MBTile files or CouchDB
add watermark to tiles

Source options:

limit sources to geometries (from Shapefile for example)
add transparency to opaque layers
merge multiple sources
reproject to other SRS

WMS Features:

build layer trees from different sources
create GetMap responses from cache with support for free-zooming and any projection (for any Desktop GIS)
accelerates existing WMS 10 to 100 times
respond to GetLegendGraphic requests
cascade GetFeatureInfo requests with optional XSL transformations
on-the-fly reprojection
convert WMS versions and image formats
