Minnerva provided MORI with a map-based data entry system used to help process survey data collected from drivers of foreign commercial vehicles in a commission undertaken for the UK Department for Transport.

The Data Entry system allowed the user to trace routes with the GIS using maps laid over survey sheets (the offset in the picture above highlights the two sets of maps that would normally be more coincident). Because many routes were similar, the system, written mainly in Map Basic, allowed the user to copy part or all of routes that had already been traced.

The tracing was controlled from a customised menu provided in MapInfo. This allowed information relating to a tracing to be acquired from the map, specifically the distance travelled along different types of routes. This information was accumulated in an MS Access database that was subject to separate analysis. Controls allowed the precision of the process to be matched with concerns of accuracy and speed.
