Model 1: Build your own Model 2: Let the Government do it Model 3: Buy Commercially Model 4: Free Commercial ServicesModel 5: Open Crowd sourcing where:
- Creating geodata is no longer expensive!!
- Much more sustainable than other models
- Not only cheaper, scope for greater detail and more timely updates.

The presentation titled: Beyond good enough? Spatial Data Quality and OpenStreetMap data, makes comparisons between Open Street Map and two Ordnance Survey data products Meridian 2 and MasterMap. At the end of the presentation the question is posed: So should I use OSM (Open Street Map)? The answer given is that OSM is fit for many purposes, positional and attribute accuracy is satisfactory. Completeness in major urban areas is satisfactory – and where it is not it is easy to improve and complete the dataset. Slide 37 of the presentation details the price of the Ordnance Survey product and then considers why one would pay such a price for product when there are other viable alternatives.
