Grapevine 17

'...the process of reading the necessary spatial data into the [geographical information] system is often very time-consuming, and hence costly. In fact it's not uncommon for data capture to account for 70~80 per cent of the cost of a GIS project. The main reason for this, is that data capture is still largely a manual process, often using a digitiser to input data from paper maps.'
- Steve in 1997
