22 Roadmap 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 Make sure to follow the talk about WorldMap by Ben Lewis from CGA later today!

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
