The State of Open Source GIS in 2011
art wins
Mapnik wins
MapBox, Stamen, Vizzuality, MapQuest
ESRI is irrelevant
data is still awful
OSM is the one true street map
Slippy Maps!
JS wins
everything else in browsers loses
Modest Maps, Polymaps, d3, Leaflet
or OpenLayers
"Vectors in Browser"
nope*
*in the real world
(not until WebGL adoption)
(and an open-source binary GeoJSON successor)
until then: Leaflet & Modest Maps
Data!
PostGIS: complex, fast, big (OSM-scale!)
SQLite: simple, big, local
CartoDB: simple, remote
most people still use shapefiles
The Future of Open Source GIS
no more projections
unless you want to care
Speed
fast data × fast rendering = iteration
fast data × fast rendering = abstraction
Consensus
lat/lon, tiling standards, data, clients, licenses
