Presentation at Lokku/Nestoria about HTML5 mapping techniques and CartoDB

1. CARTODB
AND
HTML5 MAPPING
MAPPING EVOLUTION

2. Caveats!
There are no funny pictures for ‘caveat’ on the web

3. @tokumin

7. CITIZEN SCIENCE

9. MAPS
http://rlat.kew.org/

12. Same old OSS things
Server config
Geospatial Database (backups, optimal config)
Import/export
Admin UI and config
Tiler + interactivity API
Data API
Caching
Authentication
infrastructure

13. IT SHOULDN’T BE
THIS HARD

14. Lots of services,
limited OSS
Fusion Tables
GeoIQ
GISCloud etc...
Mapbox/Tilemill?
OpenGeo Suite?
GeoDjango?
limitations

18. DEMO

19. REMOVING
BOILERPLATE
CREATES A
PLATFORM FOR
INNOVATION
Unexpected Consequences

20. Better Maps

31. Raster as canvas data source
http://localhost/ - sorry!

32. People start making libs!

33. Challenges
HTML5 acceptance
Rendering engines
Rendering Contexts
Antialiasing (CRC in alpha)
Data payloads (MapGL)
Data transfer (SPDY)
Disk IO
WebGL
Data Sources (OSM)
CartoDB
