Hi Hans, here are the desired information.
As city we received altogether 200,000,000 points from a Laserscanning flight. With the help of the "DuplicateRemover" I could already filter the double values and have now 140,000,000!!! points. For a comprehensive analysis that is still too much and I want to analyse the neighbouring points to find Points with the same height Z. For Example: P1 P2 P3 P4 P0 P5 P6 P7 P8 If point P3 has the same height (z) and/or definable altitude deviation of point P0 so I want to remove point P3. I have this situation e.g. on flat roofs. This point to point analyses already used in remote sensing. Thanks for your assistance Regards Sven P.S. We use FME2006GB Build 2651. --- In [email protected], Hans van der Maarel <[EMAIL PROTECTED]> wrote: > > geoinformatik.user wrote: > > > I have a text file (2000000 lines) with the following contents: > > > > x y z > > 4418000.000 5655055.680 216.850 > > 4428001.000 5655055.680 216.820 > > 4428003.000 5655055.680 216.830 > > 4428000.000 5655056.680 216.590 > > 4438002.000 5655056.680 216.830 > > 4433003.000 5655056.680 216.830 > > 4428000.000 5655058.680 218.590 > > 4438001.000 5655058.680 216.510 > > 4433003.000 5655058.680 214,830 > > > > Now I want to find neighbouring points with the same height (z) > > and/or points with a definable deviation of the height (z) and > > generalize this. > > > > Can you recommend a Transformer? > > A NeighbourhoodAggregator will probabely do the trick, but it depends a > bit on what you want to do.
