Seeking software for 2D height plot

[JRM]

Hi,

I'm seeking an open-source software to plot profiles on a lidar cloud where the users can manually draw the profile's line and get a 2D height plot along the axis of this profile. The aim is to allow them to create their profile on their own for studies and publication purpose.

Free proprietary tools such as LP360 or FrugoViewer offer these feature but I would like to keep the toolchain free as in sa speech as much as possible. The web viewer potree has a measurement tool which has most of the wanted features but is unable to export the 2D plot, the user is taking a screenshot of the webpage, import the raster into his vector editor (Inkscape/Illustrator), scale it manually and redraw over everything.



Regards,
JRM

Sorry for the late reply.

CC can automatically extract contours from slices but it's limited to simple contours or profiles:

http://www.cloudcompare.org/doc/wiki/in ... t_Sections

Or you can also draw the contours yourself:
http://www.cloudcompare.org/doc/wiki/in ... e_polyline

And you can export the resulting polylines to DXF.

Hi daniel and thanks for your answer,

These tools are those that I'm using when I'm the one producing the profile :
- I select the wanted profi with the cross-section tools
- an approximated contour is generated and exported to shp/dxf and used in QGIS to create a svg file with a correct scale
- I render the front view to a file (due to #385) and scale it by measuring the embedded graphic scale

I can't tell my users to do the same with CC, the global shift panel would already be a stop sign. Potree was nearly perfect in this regard as the user had most of the parameters already figured out for him and just had to focus on the length and width of his profiles. After a few hours of search, it seems there is no open-source viewer for this task.
