National Map Overview Keith Grochow, NICTA(Initiative of Commonwealth Department of Communications, NICTA and Geoscience Australia)
The Problem Main DriverThe Australian government must make data open by default. Current StateMost gov’t entities (~all) have very little experience in how to do this in a usable, reliable way.Larger organizations (Fed/State) usually have an existing content management system.Smaller ones have nothing or, if a motivated soul exists, they have an open source solution like GeoServer.The viewing solutions are limited (2D) or expensive (GE). Goal They are searching for cheaper solutions that are compelling, flexible, open, and leverable across various gov’t environments. 2
The National Map Project Initiative of Department of Communications to:Provide easy access to authoritative and other spatial data to government, business and publicFacilitate the opening of data by federal, state and local government bodiesProvide an open framework of geospatial data services that supports commercial and community innovation 3 More users using data services More data services available
Map browser code and data mgmt Govt open data directory Vision: An open national map 4 W eb browser … Value-add commercial and community services (analytics, visualisations , mashups ) Map imagery Tile map server Elevation data Terrain server C/wealth govt agency authoritative data services Internet Tablet Other data and services Data.gov.au ABS data GA data BoM data … State govt authoritative data services W A data QLD data State data …
System design goals: open national map Open data Direct service from open data repositories (like data.gov.au and similar state ones)Easy access to actual data sets from NM UI (not just visualisation)Open protocols and data formatsSupports OGC protocols (WMS, WFS), GeoJSON, KML, CSV, etc All data services can be accessed outside National Map as well as inside it Open sourceOpen source front-end; back-end data services can use open source Vendor neutral at back end (government agency ) ESRI’s ArcGIS, Google Maps Engine, open source software ( eg Geoserver)Vendor neutral at front end (browser) Work with any modern browser (Chrome, Firefox, IE9 and later, iPads, etc) Direct access from data custodian Live data service direct from government agency (or delegate) Authoritative data services Eg Administrative boundaries, place names Multi -jurisdiction Commonwealth, states, local government Multi-custodian Data from many different agencies - GA, ABS, BoM, ATO, Dept of Comms, state agenciesPlatform for commercial, community and agency innovationInterfaces to support value-add services (eg analytics, visualisation, sharing, printing)5
