Hey guys, I am producing a number of elevation grids from NTS contour data for = some maps I am working on - things are working allright with one little = exception: My grids are very "sharp" that is to say that the grid jump = in value only very close to the contour line .... I am using the = following settings: Triangulation (with smoothing) Not saving my .tri file Max Triangle Length - MI will only let me enter very small values (less = than 1)!!! Wieght factor - I have varied this between 2 and 99 with no apparant = change - is this because of my Max Triangle Length?? Exponent - Again, I have varied this with no apparant change Now, when I analyse my grid with the histogram I only get values that = are equal to the values of my contours (100, 120, 140, ect.) - It's like = the grid is not interpreting points between the contours. I understand = the trangulation forces the grid to be true to all point values, but = should it not interpolate values between the contours?? I hope that this makes sense .... Any suggestions?? Thanks a whole big bunch!!
