BD Topo project

BD Topo project for creation of a topographic data base on the territory of France was the main production project of Racurs in 2005.

Main technical characteristics:

 Input images scale: 1:25000

 Camera: F=153.972 mm

 Scanning resolution: 28 mkm

 Code table including 133 codes

 Required accuracy: 1 m (for 3D vectorization)

Racurs has processed LOT 1 and LOT 2. Twenty five blocks with the total area ~ 25000 km2 (or ~ 4.5% of the France’s territory)

Alltogether over 40 operators were trained and engaged in the project.

Specific features of the 3D vectorization:

 High accuracy requirements

 Necessity to work in 1:3, 1:4 zoom levels

 Interpretation complexity: many codes; lack of field survey; specific requirements for topology, etc.

 Time frames

 Strict requirements and formalism in quality control

 Continuous work with raster map.
