New MapProxy 1.6.0 release

September 05, 2013 at 11:00 AM

We are pleased to announce the release of MapProxy 1.6.0. It contains a lot of major and minor improvements.

The latest release is available at: http://pypi.python.org/pypi/MapProxy

To upgrade within you virtualenv:

$ pip install --upgrade --no-deps MapProxy

Updated documentation is available at: http://mapproxy.org/docs/1.6.0/

New features

Some noteworthy improvements since 1.5.0 are:

New decorate image API

There is a new API to decorate or manipulate the images returned by MapProxy. It allows you to apply image filters or to add watermarks. The API is similar to the security API.

See: http://mapproxy.org/docs/1.6.0/decorate_img.html

New SQLite and Riak cache backends

There are two new cache backends. Riak is a distributed key-value store that can be used to create high-available caches. The new SQLite cache is similar to MBTiles, but it adds timestamps for proper tile expiration and it uses one database file for each level. This makes it easy to remove complete levels without needing to VACUUM the database.

See: http://mapproxy.org/docs/1.6.0/caches.html

Improved image processing

MapProxy now supports Pillow the successor of PIL. Pillow contains improvements in PNG encoding performance and support for alpha image composition, which improves overlays of multiple transparent layers.

Usability improvements

There are multiple smaller changes that improve the overall usability of MapProxy. The deployment documentation was updated and mapproxy-util create -t base-config now creates a minimal MapProxy configuration and a full configuration with nearly all available options. Most configuration erros should now give a friendly error message instead of a stack trace.

Other fixes and changes

There are many more change, improvements and changes. For a complete list of see: http://github.com/mapproxy/mapproxy/blob/1.6.0/CHANGES.txt


3rd anniversary of MapProxy

March 22, 2013 at 11:00 AM

Today we are celebrating the third anniversary of MapProxy.

MapProxy cake

MapProxy grew from a simple tile server with WMS support to a powerful and flexible proxy for maps. Features like the security API, the ability to reproject tiles, support for coverages from Shapefiles or PostGIS and the various tools are just a few things that we couldn't have imagined to have in MapProxy when we were thinking about the future of MapProxy three years ago.

You will get an impression of the development by comparing the configuration options from the first open source release to the latest version.

With open source it is hard to tell how many users MapProxy gained in this time, but we do know that it is now used in countless projects – by federal or state agencies and institutions, by universities, students and hobbyists, by small, national and international companies – all around the world. We also know that there are 200 subscribers on the mailing list and that we get hundreds of downloads each month.

While most of the development, support and release management was made by Omniscale, all this would not have been possible without the support from various companies and institutions who funded large parts of the development of MapProxy.

We would like to thank:

  • Blackbridge Geomatics, Canada
  • Cadastral Agency of the Hanseatic City of Rostock, Germany
  • Camptocamp SA, Switzerland
  • Dienstleistungszentren Ländlicher Raum, Rhineland-Palatinate, Germany
  • Federal Agency for Cartography and Geodesy, Germany
  • GeoInformation Bremen, State Office, Germany
  • Norwegian Meteorological Institute
  • swisstopo, Federal Office of Topography, Switzerland
  • Tike, Information Centre of the Ministry of Agriculture and Forestry, Finland
  • ...

And of course, we also like to thank all contributers of MapProxy and all users that gave us valuable feedback on the mailing list, on IRC or during hands-on workshops.

The next release is coming and the list of ideas for 2.0 is growing.

On to the next three years!


New MapProxy 1.5.0 release

December 05, 2012 at 11:00 AM

We are pleased to announce the release of MapProxy 1.5.0. It contains a lot of major and minor improvements.

The latest release is available at: http://pypi.python.org/pypi/MapProxy

To upgrade within you virtualenv:

$ pip install --upgrade --no-deps MapProxy

Updated documentation is available at: http://mapproxy.org/docs/1.5.0/

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.

See: http://mapproxy.org/docs/1.5.0/auth.html#limited-to

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.

See: http://mapproxy.org/docs/1.5.0/configuration.html#format

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.

See: http://mapproxy.org/docs/1.5.0/configuration_examples.html#using-existing-caches and http://mapproxy.org/docs/1.5.0/configuration_examples.html#reprojecting-tiles

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

See: http://mapproxy.org/docs/1.5.0/mapproxy_util.html

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

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

We are pleased to announce the release of MapProxy 1.4.0. It contains major and minor improvements.

The latest release is available at: http://pypi.python.org/pypi/MapProxy

To upgrade within you virtualenv:

$ pip install --upgrade --no-deps MapProxy

Updated documentation is available at: http://mapproxy.org/docs/1.4.0/

New features

Some noteworthy improvements since 1.3.0 are:

Clipping requests to polygons

Demo service

The demo service now allows you to query WMS layers in all supported SRS. It now also supports WMTS if you have enabled this service.

Other improvements

  • WMS 1.3.0 now supports extended layer capabilities for metadata etc.
  • You can configure fallbacks for errors in tile sources. MapProxy can create an empty tile if the tile source returns a 404 not found for a tile, for example.

Note: There was a bug in the configuration loader that permitted to have an error in the layers configuration. Please make sure your configuration is valid after upgrading.
