FAQ/ LP Data Visualization¶
Can I display point clouds of LP data (laser profiler, lidar data) on a map?
response¶
You can view it. Here is an example of what you might see:
The supported format is CSV format.
It also supports CSV formats, *_grd.txt format and *_org.txt format (Manual for Preparing Digital Elevation Model (DEM) by Aerial Laser Survey (draft) (revised in April 18), p. 40).

Here are the steps on how to import it.
From the left pane of the screen, click the Objects tab.
Right-click LP Data in the Objects pane and choose Open LP Data File.
Select the files you want to target. This example shows how to open a CSV file (*_grd.txt format).
The Import LP Data dialog box appears. Set the coordinate system and the fields to be captured.
Here, 19 coordinate systems (Japan plane rectangular coordinate system) and 9 world geodetic systems were selected as coordinate systems.
I also specified field 4 (column 4 in the CSV file) as the elevation.
Press the "Import" button.
LP data was displayed on the map screen.
