Using Terrascan, is it possible to run a macro to class flightline overlap points accurately. After a macro has already been run on the lidar data to create the ground class and has been manually edited into ground, unclassed, as well as high and low points. Without needing to manually edit the ground class again. This is my first project on the processing end of lidar (macros/terrascan) and forgot to run a macro for overlap prior to running the groundclass macro. I also do have a trajectory file for the data set.

Hi, I need help to analyze some data. I have a shapefile with several attributes that correspond to polygons. Some of these polygons do not overlap, but others overlap. The polygons have several overlapping case, for example: - A polygon can exactly overlap other, or more than one. - But it may happen that one polygon is overlapped by other polygon in a location and is overlapped by three polygons in another location and in other location it is not overlap by any polygon. So what I want to do is an analysis of overlapping polygons, resulting an image where no overlapping polygons appear green, the polygon that has more than one overlay appear with different kinds of red. And, the polygon having different amounts of overlap would have different shades of red and green (in places where it had not overlap). This has to be possible to do but I 'm having some difficulty. Can anyone help me on this problem? I have done several searches but I did not find the solution. Thanks for your help .

Dear All, Does anyone know how to clean/delete automatically polygons which has overlap each other? I did using topology to fix it, but need a long time to fix it one by one (overlapped polygons raise to 5000 polygons). Please show me the fast solutions. Thanks a lot. Best, Anggoro Sudibyo
