How to interpolate and keep Z information (elevation)?

[danilo.avancini]

Hello everyone,

I have a .las file with nothing but the highest returns, and now I want to interpolate those points into a 0.5m grid to finally have my CHM. Using las2dem from LAStools the generated file sort of classifies the points into 3 groups and gives all of them the same Z value (height) (you can see this at the attached picture). The problem here is that I need the interpolated raster to display every Z information, from each point representing a pixel of my 0.5m grid, how can I get that?? Hope I've made myself clear.

Thank you in advance.

Hello Danilo,

unfortunately I have no clue what you are doing and what the problem is from the way you describe it. Could you

* send a lasinfo report for the input LAS / LAZ file (text, no screen shot)

* detail the exact las2dem command line you are using  (text, no screen shot)

* run las2dem with the '-v' option for more verbose console output

* copy and paste the entire console output (text, no screen shot)

* and ideally ... include a Web-link to the LAZ file that gives you trouble

Regards,

Martin @rapidlasso
