Comparisons Line Mapping – Orthophoto Mapping
Cost considerations 2006:
- German Labour and Eqipment Overhead Costs in black
- Chinese Labour Costs (and no Equipment Overhead Costsin China, as the HW/SW is donated to the enterprises bythe government) in red(this is why Indian costs are higher than the Chinese)
Compiled by Gottfried Konecny, University of Hannover, Germany
Orthophoto Mapping versus Line Mapping - Costs
1. Aerial Photography:constant fee of $5000 in season
$3000 out of season10$ per image (in China: 4 bis 30$ per image 1:12 000 to 1:5000)
2. Scanning of aerial photos15$ per image
(in China: 2 bis 4 $ per imageo (BW to color)
3. Aerial Triangulation
25$ per image (in China: 8 $ per image)
57
Photogrammetric Costs (cont‘d)
4. Digital Elevation Model via Image Correlation
120$ per image (in China 10 $ per image)
5. Digital Orthophoto Production
30$ per image (in China 3 $ per image)
6. Matching and Mosaicking of Orthophotos20$ per image (in China 2 $ per image)
7. Vectorization in 2 or 3Drural area at 10hrs. (8 hrs) per imageurban area at 100hrs. (16 hrs) per image(40$ per hr. in Germany, (15$) 25$ per hr. in China or India)
