This document provides an introduction and demo of GeoNode, an open source platform that allows users to easily share geospatial data and create web maps. The summary highlights that GeoNode was initially developed by the World Bank and Open Plans in 2010 and is now used by various organizations for mapping and sharing geospatial data. It also provides an overview of GeoNode's architecture, which uses Python, Django, GeoServer, PostgreSQL/PostGIS and other open source tools to enable features like map creation, data editing and metadata management.

Improvement by other GeoNode developers:
● 2.5+ GeoNode API improvements
● 2.5+ Support for additional web map engines (QGIS Server,
MapServer, Mapnik)

23. Roadmap: from WorldMap to GeoNode
Some features will be ported from WorldMap GeoNode to
mainstream GeoNode (version 2.5):
● 2.5 Classify by attribute styler
● 2.5 Map Notes
● 2.5 Map snapshots/revisions
● 2.5 Create layer capability
● 2.5 Gazetteer from layers

24. Roadmap: from WorldMap to GeoNode
Some features will be ported from WorldMap GeoNode to mainstream
GeoNode:
● Datatables (table joins, lat/lon csv file upload)
● 2.5+ Map service registry to support search and discovery across
distributed GeoNode systems and across any system which contains OGC
or Esri services (HHypermap)
● 2.5+ Feature Search
● 2.5+ a big data, real time geo visualization system

25. GeoNode Stack
● Python, Django
● GeoServer
● PostgreSQL/PostGIS
● Pycsw or GeoNetwork
● GeoExplorer or MapLoom
● Optional: GeoGig, Solr or Elastic Search
All open source!

26. GeoNode Stack: Django
Django is a high-level Python Web framework that encourages rapid development and
clean, pragmatic design. Built by experienced developers, it takes care of much of the
hassle of Web development, so you can focus on writing your app without needing to
reinvent the wheel. It’s free and open source.

27. GeoNode Stack: GeoServer
● An open source web mapping engine
● Implements a number of OGC standards
○ WMS
○ WFS/WFS-T
○ WCS
○ WMTS (with GeoWebCache)
○ WPS
● Exposes a REST API

28. GeoNode Stack: PostgreSQL/PostGIS
PostGIS is a spatial database extender for
PostgreSQL object-relational database
SELECT city.name
FROM city, country
WHERE ST_Contains(city.geom, country.
geom)
AND country.name = 'United States';

29. GeoNode Stack: pycsw
● A metadata publishing and discovery engine written in
Python
● OGC CSW reference implementation
● It is possible to use GeoNetwork as an alternative

30. GeoNode Stack: GeoExplorer
● It is the default mapping client in GeoNode
● Based on ExtJS, GeoExt and OpenLayers 2
● It enables feature such as data editing, style editor, map query, map print

31. GeoNode Stack: MapLoom (optional)
● Can be used in place of GeoExplorer
● Based on OpenLayers 3, Angular and Bootstrap
● Enables GeoGig integration for feature versioning

32. GeoNode Stack: GeoGig (optional)
● Tracks change to data
● History of features
● Revert a feature to its old version
● Integrated in GeoNode with the MapLoom client
● Already used in many GeoNode instance created for natural
disasters (ex response to Typhoon Yolanda in Philippines)

33. GeoNode Stack: Search Engine (optional)
● It is possible to improve the search features of GeoNode with
a dedicated search engine
● Two alternatives, both based on Lucene
○ Apache Solr (used in WorldMap)
○ Elasticsearch

34. GeoNode Stack: underlying libraries
● GDAL
● OGR
● GEOS
● PROJ.4
● GeoTools

35. Demo
● Create a new layer from a shapefile
● Create a map adding the layer and some remote datasets
● Style the layer using GeoExplorer
● Edit the layer with GeoExplorer and WFS-T
● Define permissions on the layer
● Update metadata
● Load a layer in desktop GIS
