ACCURACY OF DIGITAL ELEVATION MODELS FOR THE MORPHOMETRIC ANALYSIS OF WATERSHEDS
Finally, the consistency of morphometric data can be improved by performing manual vectoriza ion of the drainage divide and watershed perimeter a ter automa ic vectoriza ion, thus increasing accuracy in rela ion to reality on the ground. Similarly, manual vectoriza ion of the main river improves the accuracy of the parameters related to this variable.
