Salutations,
I'm having trouble getting the point cloud and geotiff file to layer. The steps I've taken are included below. After opening a MicroStation photogrammetry 3D seed file, I:
1) Set the Geographic Coordinate System to match the LiDAR data. 2) Download a National Agriculture Imagery Program (NAIP) map (http://datagateway.nrcs.usda.gov/GDGOrder.aspx)
3) Attach the NAIP map using Raster Manager.
4) Download LiDAR .laz files from William and Mary's Geospatial site (http://www.wm.edu/as/cga/VALIDAR/)
5) Merge and filter the laz tiles using LasZip.
6) Create a .pod file from the .las file using Bently Pointools V8i and attach it to Microstation using Point Clouds. The two pink boxes below illuminate what I end up with. The files do not overlap and the LiDAR data is much larger than the map. Please help.

Hi Dawn,
First the raster is currently not reprojected. Since its GCS is different the GCS of the model you should uncheck the Inherit GeoCS From Model column.
Also there is no GCS assigned to your POD file. According to http://gisfiles.wm.edu/files/lidar/ESLiDAR/metadata/ESVA_2010_LiDAR_Final_Report.pdfthe GCS of the point cloud data is HARN StatePlane Virginia South FIPS 4502, which seems to be equivalent to the GCS EPSG 102747 in MicroStation.
So you should try setting the GCS of your POD file to EPSG 102747.
Finally the point cloud data are in feet. I suspect that when you created the POD file you specify Meters as the Geometry Unit. If so, you should try recreating the POD file by specifying Feet instead.
Thanks,
Mathieu
