Currently I am working with two data set ASTER and SRTM. I want to check their accuracy with reference to toposheet.
How would I do that in ArcGIS Desktop 10.4?
I want to check accuracy in terms of area and length of my study area.

i am yet to figure out how to compare these two data-set. I want to check weather there is any substantial difference in the derived DEM of the two satellite imagery which I am using – Subham Shree Feb 17 '17 at 7:49

1What format is your topo data? Raster topo map, topographic vectors (contours, spot elevations, survey controls etc)? – user2856 Feb 17 '17 at 8:20

It is in contour format. – Subham Shree Feb 17 '17 at 14:40

Digitize manually the polygons on the raster data which you want to compare and do the comparison.
