Individual tree location /stem detection using lastools

[spete...@gmail.com]

Hello,

I am working with 4-8 ppm2 airborne lidar data of even-aged single species pine tree forests in South Australia. 

My goal is to detect individual trees (and tree crowns). Based on literature, there are different solutions depending on the type of forest and lidar point density. 

If I am not mistaken, lastools doesn't have a solution for tree identification (?). In this forum potential solutions were mentioned - producing isolines etc.

I was wondering if someone has had a similar task or solution using lastools and or other software?

Best greetings

Stefan

Hi Stefan,

We are still using canopy maxima from FUSION, waiting for Martin to implement it in LAStools 😊

Cheers

Susana

Hi Stefan,

 

Considering LasTools hasn’t have a tree detection algorithm, you can always consider R (CRAN):

Hi Stefan,

we developed some tools for treetops extraction in the JGrassTools library (http://moovida.github.io/jgrasstools/), which can be used now as a plugin for gvSIG (https://blog.gvsig.org/2017/03/02/on-the-road-to-gvsig-2-4-jgrasstools-and-geopaparazzi-plugins-for-gvsig-desktop/).

Here you can find the basic tools.

Do you also have field data for verifying the results?

Best regards

Silvia

Hi Stefan,

I have recently used Forest Tools package in R for individual tree detection.
