Isopleth zones prepared on basis of grid-wise difference of each dataset’s mean elevation values from the corresponding values of the SoI 1:50,000 topographical map. Relatively lesser positive (T50A values are higher) or negative (T50A values are lower) difference ranges imply a higher match with the topographical map values. Difference with ASTER 30 m (a), difference with resampled ASTER 90 m (b), difference with CartoDEM 30 m (c), difference with resampled CartoDEM 90 m (d), difference with SRTM 90 m (e), difference with resampled 90 m DEM from 1:50,000 SoI toposheet (f), difference with 1:250,000 USAMS toposheet (g), difference with resampled 90 m DEM from 1:250,000 USAMS elevation zone maps (h)
