Useful Information for Third-Party Data Integration.

PCRAFI - Pacific Risk Information System is an open service built on open source software. We encourage you to build new applications using the components and resources it provides. This page is a starting point for advanced users and developers interesting in taking full advantage of the system. It also includes links to the project's OGC-complaint web services so anyone can build and customize their own datasets.

Software Componenets

All the code that runs Pacific Risk Information System is open source. The code is available at http://github.com/sopac/pacgeo/.

The system is built using several open source projects, each with its own community. If you are interested in contributing new features to the GeoNode, we encourage you to do so by contributing to one of the projects on which it is built:

  • GeoExt - The JavaScript toolkit for rich web mapping applications
  • GeoServer - Standards based server for geospatial information
  • GeoWebCache - Cache engine for WMS Tiles
  • OpenLayers - Pure JavaScript library powering the maps of GeoExt
  • pycsw - CSW metadata catalogue server

What are OGC Services?

The data in this application is served using open standards endorsed by the Open Geospatial Consortium; in particular, WMS (Web Map Service) is used for accessing maps, WFS (Web Feature Service) is used for accessing vector data, and WCS (Web Coverage Service) is used for accessing raster data. WMC (Web Map Context Documents) is used for sharing maps. You can use these services in your own applications using libraries such as OpenLayers, GeoTools, and OGR (all of which are open-source software and available at zero cost).

What is GeoWebCache?

GeoWebCache provides mapping tiles that are compatible with a number of mapping engines, including Google Maps, Bing Maps and OpenLayers. All the data hosted by GeoNode is also available through GeoWebCache. GeoWebCache improves on WMS by caching data and providing more responsive maps.
