Kantey & Templer Consulting Engineers has made extensive use of AllyCAD to complete the capture of the road centrelines for the entire Greater Johannesburg area. In an area of some 1200 sq km, extending from Diepsloot in the north, Orange Farm in the south and in the west from Protea Glen to Herriotdale in the east, K&T; used digital aerial photography as a spatial backdrop to draw lines and to capture information. In total, some 9000 km of road centrelines and GIS attribute data were captured. This project is still ongoing in that unpaved roads in newly established townships are being captured to complete the entire road network. The capture of all roadside stormwater network data is now being added to the centreline data.

Project Director for K&T, Barry Alport, says: "Using AllyCAD we were able to index and view a mosaic of 12 GB of digital images quickly and easily with software and hardware at a fraction of the cost compared to competitive software products."

Clients for this project are the four local Johannesburg Metropolitan Councils, viz Northern, Southern, Eastern and Western, as well as the Johannesburg Roads and Stormwater Agency.
