Dear Sir,
Greetings to all,
I would like to know the what is the best accuracy of DEM, with respect to
point interpolation in Ilwis. we collecte spot height data from 1:50,000
toposheets and interpolated (moving average),we got RMS error around 1.34
meters for the points 2000, and sample points 100. If anyone sugest, what
is the method to improve quality of DEM and is that error is normal or
not? If anyone have some supported papers or article regarding accuracy
analysis and standards in Ilwis, please send it to me either in hard or
soft. I am very much grateful to you..
Yours sincerely
G.prasad Babu

Love suffers long and is kind; love does not envy; love does not parade
itself, is not puffed up;
does not behave rudely, does not seek its own, is not provoked, thinks no
evil;
does not rejoice in iniquity, but rejoice in the truth;
bears all things, believes all things, hopes all things, endures all
things.
Love never fails. But whether there are prophecies, they will fail;
whether there are tongues, they will cease; whether there is knowledge, it
will vanish away.
I Corinthians 13:4-8
