I am trying to reproject LAS datasets derived from Pix4D photogrammetry output of a UAV flight that were created with the WGS_1984_UTM_Zone_17N / VCS:WGS_1984 (Z unit is meters above ellipsoid) spatial reference so that it can align with other third-party LAS dataset (traditional lidar; not photogrammetry) in the NAD_1983_StatePlane_Pennsylvania_South_FIPS_3702_Feet / VCS:NAVD88_height_ (Z unit is Ft_US) spatial reference. The Extract LAS (3D Analyst)—ArcGIS Pro | Documentation, it explains that the LAS data can be reprojected using the Output Coordinate System environment and it is claimed: 'If the spatial reference contains a vertical coordinate system, the LAS files can also be reprojected to another height reference system if the vertical datum transformation grids are installed and a transformation is available from the source reference and the target coordinate system.' I have the Coordinate System for ArcGIS grids installed and the appropriate transformation is set in the Map/Scene Properties and everything is projected on-the-fly brilliantly in the map and scenes when viewed. The highlighted transformation below is what is selected in the Map/Scene Properties > Transformation for the above coordinate systems.  However, I cannot set the Geographic Transformation environment setting to match the above compound transformation, so I left it blank hoping the software would choose the appropriate XY and Z transformations. However, the Geographic Transformations (Environment setting)—ArcGIS Pro | Documentation says that 'compound transformations' are not valid in the environment setting (which makes me think that this particular transformation is not possible in this tool). So, when I run the Extract LAS tool, the vertical location of the points are not transformed/reprojected (while the horizontally they are), and instead appear to be located in the original Z coordinate system, which in this case is below the expected vertical location. So is the claim that the Z coordinate system for LAS data can be reprojected false? Am I missing something? Any guidance would be appreciated. This will likely be mission critical for me. Thanks. ...

I am working with downloaded USGS/VGIN LIDAR which I can convert to LAS and build a LAS dataset from; however, I can not convert to Raster. All other processes are working (I can create a scene, add contour, identify outliers, etc...) but LAS dataset to Raster gives me this error: Any ideas why this is not working?  ... View more

Hello All,     I am trying to develop a map that has accurate line of sight calculations for a point to point system.   Trees are my main issue.  I have been looking for accurate lidar data and I am striking out so far.   It am trying to avoid breaking the piggy bank and shelling out the $$$ for a drone with a lidar camera.   Does anyone know where I can get (free or paid) current (<2 years old)accurate lidar data?  I need it for the  Eastern Kansas Region (Lawrence-Leavenworth) and Western Missouri (Oak Grove-Odessa) specifically.  Or does anyone have any experience/ideas/resources they could point me to.  Thanks in advance. ...

Hi, I'm working with information taken by a UAV system, I have obtained high density point cloud, around 75 million points. I'm analizing all my data in ArcGIS Pro but I'm having problems:  - Sometimes the point cloud data loads and it doesn't show in the screen. - In other time I load the data and the software suddenly closes. Maybe, it is a limit amount of the data that we can work in ArcGIS Pro or there is another way to do that? ... View more
