Quality assessment digital elevation models
نویسنده
چکیده
A number of published stereo matching algorithms have been implemented and tested on SPOT images of areas for which we have gridded digital elevation models (DEMs) available with spacings of 80m or less as well as ground control checkpoints. Results will be presented for a comparison of stereo matched output with the DEMs and an analysis of the errors arising and their causes. Results will be discussed for planimetrically geocoded and epipolar resampled data .. An error budget describing effects due to orientation, feature localisation and matching will be discussed and conclusions drawn for future work in this area.

متن کاملHIGH RESOLUTION DEMs AND ORTHO-IMAGE BASEMAPS FOR LOCAL GOVERNMENT APPLICATIONS
STATEMENT OF PROBLEM Digital Elevation Models (DEMs) are the digital representation of topographic and/or manmade features located on the surface of the earth. DEMs are widely used for hydrologic analyses, resource management, transportation planning, earth sciences, and environmental assessment. Increased use of DEMs in these wide-ranging applications has led to greater need for higher resolut...
