The State of Open Source GIS in 2011

art wins

ds.io/t5NSNa
MapBox

ds.io/sD30aw
Stamen

Mapnik wins
MapBox, Stamen, Vizzuality, MapQuest

ESRI is irrelevant

data is still awful

OSM is the one true street map

ds.io/uvLdbp But using it is a headache

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

Dear academics:

More laptops Less posterboard
