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… (Show more)

Hi there, I work with building foortprint and ground contour shp files in Projected Coordinate system WGS_1984_World_Mercator. I also brought a las file of the area but that one is available in the Coordinate system GDA_1994_MGA_Zone_55. Inside the ArcGIS environment, the building polylines, the terrain contours and the las data seem to overlay… (Show more)

Click to view contentI 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… (Show more)

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… (Show more)

What is the difference between LAS ESRI and LAS USGS formats? I see both types available for a number of Wisconsin county LiDAR data sets.

Hi, I need to create scene with 1000+ Las. I would like to replicate my single small LAS (30MB) in 1000+ different position. Is there a tool or steps that I can follow to achieve this goal? Thanks

We are going to get a test iPad with the new Lidar in it.  My fear is that it is apple only format and I will not be able to get a las file or similar out of it.  I cannot seem to find any info on this.   Anyone know anything?   Thanks

Hi All,    I downloaded Lidar data from NOAA and am looking to use it to assess possible trout spawning areas in the Lower Saluda River in South Carolina. The data I downloaded is in TIFF format. What are some possible workflows that I could execute to assess the data to find spawning habitat in the river? I know how to perform trained… (Show more)

Click to view contentI've colorized a LAS dataset with NAIP imagery for my county but some tiles have picked up 0,0,0 RGB information at the imagery's border and this causes black points to appear in the point cloud alongside the colored points. I've tried adding a clip constraint (hard and soft) but nothing happens; the LAS dataset still draws points outside the clip… (Show more)
