Client : A 260 sq mile county in California.

Input : Raw aerial images, camera report, ground control points & flight data.

Deliverable : Detailed Topographical Map.

A full topographical map was created with 5 foot Contour Intervals (CI) for the urban area and 10 foot Contour Intervals (CI) for the rural area. Using the softcopy photogrammetry stereo plotters, DEM points were captured at regular intervals of 50' (5' CI) and 100' (10' CI) with adequate breaklines wherever necessary capturing all the planemetric features like roads, utilities, parking lots, water bodies, buildings etc. Approximately there were 210 stereo models covering an area of around 260 sq miles.
