Django WMS Browser Context: In the interest of improving compatibility with existing infrastructure, GeoNode should allow "adding" or "subscribing" to a 3rd-party WMS service and providing a browser-accessible and human-readable presentation of the layers presented. As a first step toward that goal, is to create a standalone app/service to translate WMS Capabilities to HTML. Details: Configuration: An administrator should need only to provide the URL to a WMS service or Capabilities document and allow the rest to be inferred from data available via OGC web services. Presentation: * The index page for the site will be a listing of all known layers, with appropriate navigation aids. * Clicking on a layer link from the index page brings up a 'detail' page for the layer, presenting the layer's title and other metadata, as well as an interactive ('slippy') map to allow browsing through the contents of each layer. * For non-raster layers, users should also be able to explore the attribute data associated with the geometries in a table. * Each layer should include instructions (code templates etc.) for integrating the layer into other services such as OpenLayers maps. Prerequisites: * GeoDjango http://code.djangoproject.com/wiki/GeoDjango * Spatial Database (tested with PostgreSQL + PostGIS, assumed, but not tested, to work with MySQL and Oracle Spatial) * OWSLib http://trac.gispython.org/lab/wiki/OwsLib (using forked version wiht improvements here https://github.com/ortelius/OWSLib) * BeautifulSoup http://www.crummy.com/software/BeautifulSoup/ * olwidget http://github.com/yourcelf/olwidget General TODO: (in Priority Order) Implement Basic Doctests Tests for Model Functions Implement Unit Tests for Model Functions -WmsEndpoint.parse_save_wms_url WmsEndpoint.parse_save_output_formats WmsEndpoint.parse_save_capabilities WmsEndpoint.parse_save_wms_layers WmsLayer.generate_preview_image WmsLayer.parse_save_styles WmsLayer.generate_preview_image WmsLayer.retrieve_layer_attributes WmsLayer.valid_latlon_bbox WmsLayer.parse_save_layer_attribution WmsLayer.parse_save_style -Implement index view in wmsb.views -Implement index template -List all exiting layers -> Link to WmsLayer info view -Navigation/Paging Form to add new endpoint/server (single form field for url) -Implement Endpoint/Server listing view in wmsb.views -Implement Endpont/Server listing template -List of all exisitng Endpoint/Servers -> Link to WmsEndpoint info view -Navigation/Paging Form to add new endpoint/server (single form field for url) -Implement WmsEndpoint info/detail view in wmsb.views -List all layers for Endpoint/Server OL Map with footprints for each layer? -Implement WmsLayer info/detail view in wmsb.views -Implement WmsLayer template List all layer metadata -List Layer Attributes (if available) in table. -OL Map with WMS Layer Code Templaes for embedding OpenLayers Google Maps Google Earth/KML?
