RoadmapImprovement by other GeoNode developers:

● 2.5+ GeoNode API improvements

● 2.5+ Support for additional web map engines (QGIS Server,

MapServer, Mapnik)

Roadmap: from WorldMap to GeoNodeSome 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

Roadmap: from WorldMap to GeoNodeSome 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

GeoNode Stack● Python, Django

● GeoServer

● PostgreSQL/PostGIS

● Pycsw or GeoNetwork

● GeoExplorer or MapLoom

● Optional: GeoGig, Solr or Elastic Search

All open source!

GeoNode Stack: DjangoDjango 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.

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

GeoNode Stack: PostgreSQL/PostGISPostGIS 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';

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

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

GeoNode Stack: MapLoom (optional)● Can be used in place of GeoExplorer

● Based on OpenLayers 3, Angular and Bootstrap

● Enables GeoGig integration for feature versioning

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)

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

GeoNode Stack: underlying libraries● GDAL

● OGR

● GEOS

● PROJ.4

● GeoTools

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
