Hello FME-Community,
I am working with FME desktop 2017 and LiDAR point clouds. I have selected a certain number of LiDAR points that intersect with a polygon (shape). All these points belong to class 5 (tall vegetation), but I would like to reclassify them as class 6 (buildings).
I have not been able to find any tool that makes this reclassification. Could you help me or give me an idea?Thank you very much.
Hello @cesar_vicente, how are you?
Did you watch this Webinar ? How to get the most out of lidar data
I believe there are interesting Workspaces and slides about the Lidar.
Thanks,
Danilo
Hi @cesar_vicente, have a look at the PointCloudExpressionEvaluator.
Hello @takashi. PointCloudExpressionEvaluator performs the reclassification of LiDAR points just as I want. Perfect
However, now I have another difficulty. I have already reclassified the class 5 points in class 6. These points I have obtained from trimming the point cloud with a polygon (with clipper transformer). Now I want to collect the reclassified points with the original point cloud. I tried with PointCloudMerger transformer, but I can not join the points and get the same number of points as the initial point cloud.
Is it possible that there is another tool to do this process? Or maybe there is a tool that allows you to make a selection of points (class 5) from a polygon and without the need to make a clip? If my explanation is not correct, I can explain again.
Thank you very much for your help and your time.
