T. Toutin, SPOT AND LANDSAT STEREO FUSION FOR DATA EXTRACTION OVER MOUNTAINOUS AREAS, Photogrammetric engineering and remote sensing, 64(2), 1998, pp. 109-113
In thematic and cartographic applications, planimetric features are ex
tracted from multi-sensor images such as SPOT and Landsat in order to
take advantage of their complimentarity features. When no precise elev
ation data are available to ortho-rectify these images, e.g., in mount
ainous areas, stereo digital photogrammetric workstations (stereo DPWS
) are now available for the interactive stereo fusion and plotting of
multi-sensor stereo pairs. This paper presents a method and the quanti
tative results on the extraction of planimetric and altimetric feature
s from a stereo pair generated with mixed sensor images (SPOT-P and La
ndsat TM) using the stereo DPWS, the DVP available at the Canada Centr
e for Remote Sensing. Results from this mixed sensor stereo pair, whic
h hits a base-to-height ratio of 0.49 and was taken over a mountainous
area of the Rocky Mountains (Canada), show a planimetric accuracy of
11 to 12 m for well identified cartographic features, and an altimetri
c accuracy of 37 m for the extracted elevation data.
