Lecture 10 - Interactive Maps, Collaborative Mapping, Open Data and Systems
• To take something to invest, need minimum viable product (MVP)
Maps of Antipodality
• Antipodes - points on opposite sides of earth
• E.g. nz and spain
• Easy to work out geographically
• Two locations of opposite sides of the world
Proprietary vs. Open Systems
• Historically, GIS has involved:
o Proprietary software: E.g. ArcGIS, Google maps
o Proprietary file formats: e.g. shapefiles, ERMapper
o Proprietary datasets: e.g. commercial aerial images, LIDAR data
o In-house development (e.g. councils) (overlay maps)
o Data release under copyright
• The move today is towards open networks
o Open source software: grassGIS, openlayers, geonode, D3 JS,
freemium
o Open geospatial consortium standards: KML, WMS, SLD
o Public domain sources: e.g. out of copyright, US government
o Crowd sourcing: e.g. Wikipedia, open street maps
o Data sharing: e.g. creative commons licence
Finding Open Datasets
• Worldwide
o GapMinder
▪ Datasets now working, or look up source organisation
▪ World Bank
▪ All US Government organisations: NASA, NOAA, CIA
• Creative Commons
o Wikipedia
