Hello, I'm working with the UTM projection, I get a kml file from google Earth and I map the geographical coordinates to UTM prjection coordinates, and I think I might have got an accuracy lack,I have used this code according to Matlab mapping toolbox help :
zonaUTM='30S' utmstruct = defaultm('utm'); utmstruct.zone = zonaUTM; [ellipsoid,estr] = utmgeoid(zonaUTM); utmstruct.geoid = ellipsoid; utmstruct = defaultm(utmstruct);
But after, I have searched in google possible trouble with UTM, and I have found out this link:
<http://www.mathworks.com/support/solutions/en/data/1-5Q9JAC/index.html?product=MG&solution=1-5Q9JAC>
And now, I'm bewildered,due to the fact I don't know if I should change the geoid or not. Could anyone help me with?
Thanks,Javier
