Wait, you're thinking: Who are you and what's the point?

We are Paul and Joe. And we want to expand your toolkit.

Last time we talked about OS GIS: we were new - it was generic.

We'll focus on Open Source GIS on Windows.

Windows, because: 84%.

Let's get it started! Quantum GIS

Methods: OSGeo4W or Standalone

QGIS Workshop CGA Harvard University.

QGIS

plugins

FWTools
command line toolkit
very powerful

Reproject data & change format:
ogr2ogr -f "KML" -t_srs EPSG:4326 output.kml input.shp

Info about a Shapefile:
ogrinfo -al input.shp

GeoTiff from georeferenced Tiff:
geotifcp -e abc.tfw abc.tif geo_abc.tif

This code will export all your postgis tables into a folder called mydatadump in Shapefile format.
ogr2ogr -f "ESRI Shapefile" mydatadump PG:"host=myhost user=myloginname dbname=mydbname password=mypassword"

Install PostgreSQL + PostGIS (through StackBuilder) to get right into it.

One Stop Shop: OpenGeo Workshop + installer. For great introduction, easy setup.

Use case3: .csv -> TileMill

What about Google Maps API?
