#TO: QGIS
Postgres/PostGIS instanceiShareGISMap-Modeller
# Saving around £15k in Yr one

# Scalability
# Cost savings
# Technology
# I wanted GIS on every desktop!

Desktop GIS!
QGIS: CAN
# Edit shp, PostGIS # Query features # Print map# View WMS etc# Open shp, tab, kml etc# Smaller hardware footprint# Can be virtualised
No license costs associated with scaling up!
