papyrus_ogcserver

papyrus_ogcserver provides an easy and convenient method for embeding a Mapnik OGCServer into Pyramid applications.

papyrus_ogcserver is based on papyrus_tilecache by Éric Lemoine https://github.com/elemoine/papyrus_tilecache

Install

Installing Papyrus in an isolated virtualenv is recommended

papyrus_ogcserver is installed using the applications setup.py

$ python papyrus_ogcserver/setup.py install

Often you'll want to make papyrus_ogcserver a dependency of your Pyramid application, which is done by adding papyrus_ogcserver to the install_requires list defined in the Pyramid application's setup.py file.

Embed Mapnik OGCServer

Embeding a Mapnik OGCServer in a Pyramid application is easy.

Edit the application's development.ini file and, in the main section ([app:]), set ogcserver_config to the location of the OGCServer config file. Example:

[app:MyApp]
use = egg:MyApp
...
ogcserver_config = %(here)s/ogcserver.conf

In this example the OGCServer config file is located at the same location as the development.ini file.

An example ogcserver.conf is included and additional information is available at the mapnik ogcserver repository https://github.com/mapnik/OGCServer regarding the ogcserver configuration file.

The map itself is constructed in one of two ways: using either a mapnik xml file or using pure python through a WMSFactory.

1.) To use an xml defined map edit the application's development.ini

file and in the main section ([app:]), set mapfile to the location of the mapnik xml file.

2.) To use a python WMSFactory edit the application's development.ini

file and in the main section ([app:]), set server_module to the name of the module containing the MapFactory class (without extension .py)

Now, edit the application's main file, __init__.py, and register papyrus_ogcserver using the Configurator.include method:

def main(global_config, **settings):

    config = Configurator(settings=settings)

    import papyrus_ogcserver
    config.include(papyrus_ogcserver)

That's it! The Pyramid application now exposes a Mapnik OGCServer service at /ogcserver.
