Challenges moving to Open Source
• Effective methods of displaying data
• Inaccurate data on open source maps
• Cached tiles show outdated data
• Open source bugs + support

ArcGIS Online: Comprehensive feature list. Jack of all trades, master of none. Confusing pricing. Card carrying ESRI users will love it. CartoDB: A GIS programmers wet dream. The power of PostGIS and Mapnik but none of the setup headache, all wrapped in attractive packaging. GISCloud: Online alternative to traditional client/server GIS setup. Many features but hampered by a frustrating user interface. GeoCommons: The place to share your data and use the data of others. No coding required. Slick UI, great visualisation tools. MangoMap: The quickest way for GIS users to publish web maps. No coding required. Lots of map features, slick UI that’s geared towards simplicity. MapBox: Making maps sexy again. Programmer focused. Great for maps that need to fit a brand and be able to scale for high traffic.
