5.6 Ground Sample Distance: The distance between 4
concrete slabs painted using lime powder was measured in
DGPS mode. Distance measured by Theodolite is expected to
have an accuracy of 10 cms. The difference in computed
distances, using SSP mode coordinates, varies from —3.3 m to
*4.5 m. The difference in computed distances, using DGPS
mode coordinates, is within 0.9 m. Distance computed in TES
Geo-Reference product matches in across track direction within
0.8 m but in along track direction the deviation is of the order
