1. THE FUTURE OF GEOSPATIAL DATA FORMATS AT CARTODB @ANDREWXHILL
2. Life has been good with map tiles
6. At the end of the day, they are all still just <img>
7. They’ve lulled us into a world of just a few projections
8. = They don’t scale much past 1
9. A funny concept for zoom
10. http://bit.ly/10d3AF1
11. /api/v2/sql?format=JSON /api/v2/sql?format=GeoJSON /api/v2/sql?format=TopoJSON /api/v2/sql?format=bin
13. Raw GeoJSON: 9.1 MB ESRI Shapefile: 3.5 MB Raw TopoJSON: 1.7MB
14. https://github.com/Vizzuality/vecnik Use the browser to do the rendering
16. Torque 0.1
17. Torque 1.0 3000x speedup Even more efficient transfer format More efficient DOM management
18. Torque x.x
19. Flexible formats that fit the task Built for the modern web Built for dynamic and non-static data
20. SVG PNG Tiles JSON GeoJSON TopoJSON Torque KML BIN
