| Summary: | In this paper, we analysed and compared the
digital elevation model (DEM) based on high resolution
QuickBird and Pleiades satellite stereo images. 3D maps were
generated for objects like trees near poles of power transmission
lines using satellite stereo images. This study was very
challenging due to weather condition, hilly and non-uniform
terrain at Kota kina balu in East Malaysia. First we require the
geometric accuracy of these two sensors for 3D mapping of the
area of interest. Also we require accurate Digital elevation model
for better height calculation of vegetation/trees near power poles.
For these purposes, we evaluated the accuracy of DEM using
high resolution satellite stereo imagery. The comparison was
made based on RPC coefficients and ground control point’s
measurement (GCP). Results shown that the Pleiades satellite
sensor is feasible for generating the elevation model for small
area. This shows that Pleiades sensor can be used for monitoring
the vegetation near poles of high transmission power lines based
on the satellite stereo images. |
