Hello,
I am trying to take USGS LiDAR data (.LAZ format), process it in ReCap to create a point cloud (.RCP format), bring that point cloud into Civil3D 26, and create a TIN surface.
The .LAZ file can be found in the following Dropbox link:
My problem is that when I bring the .RCP into Civil3D, it places the cloud way out in space, away from where it should be. I've tried setting my 'INSUNITS' to 2, 6, and 21, and changing my Civil3D coordinate system to match the .LAZ file's coord. system to no avail. I found another thread from 2022 about this issue, but could not get it resolved following those steps. Any guidance would be much appreciated.
My process is as follows:
- Import .LAZ file into ReCap {Downloaded from here: https://www.sciencebase.gov/catalog/item/64c9edc9d34e70357a34dfa9}
- (Image 1) Set the current coord. system to NSRS11.CA-IVF (EPSG 6422) {Found via WESM.csv downloaded here: https://rockyweb.usgs.gov/outgoing/TNM_Help/Documents/EPSG_Code_and_Projection.pdf}
- (Image 1) Set the target coord. system to CA83-IVF (EPSG 2228)
- Index the scan and launch project.
- Remove all point classifications except for ground points
- Export as .RCP
- (Image 2) Insert the .RCP via the "Attach Point Cloud" command under the "Insert Tab" in Civil3D {blue circle is about where it should go}
- (Image 3) Select "Use geographic location" under the prompt window.
- (Image 4) Then it drops the point cloud way out in space.
