Generate Points for Waterbodies in LP360

Introduction In many cases there are not many LIDAR returns from the surface of waterbodies, and sometimes none at all. In some situations, it is useful to have points that can represent the surface of these waterbodies. LP360 can be used to generate points for these areas and mark them as synthetic points. Methodology Generate…

LP360 in the Classroom: Pennsylvania State University

A Letter from Jolynn Schmidt My final project for my LIDAR class was to extract building heights using LIDAR collected after Superstorm Sandy for the City of Newark.  Using LP360, I created a Point Cloud Task workflow to classify points within a set of building footprints. My final product included a DEM of the ground…

Photoscan – Editing Orthomosaics

Photoscan has a function to assign only user selected images for a specific area. This is useful for cleaning up areas of the ortho that have: blurriness, moving vehicles, bad image stitching, etc. 1. To begin, make sure that you have selected to view the orthomosaic, draw a polygon around the area in the orthomosaic…

PhotoScan Processing with Duplicate Photo Names.

When importing adjusted photo heights into PhotoScan, the photo name is used to attach the adjusted image height to the photo in the PhotoScan project. The photo numbering system used by DJI aircraft starts at DJI_ 0001 and goes up to DJI_0999.   When the number of photos exceeds DJI_0999, the photo count starts back over…

ASPSuite – Adjust Heights Workflow

To process images in PhotoScan using control points, it is important for the image heights to be relative to the same vertical datum as the control points. Some drone models cannot determine their height relative to a vertical datum but can accurately determine their height above the takeoff location. If the takeoff elevation is known,…
