We are in continuous progress to inprove our software and extend our service to all customers.
There are several sites in the internet where you can get information and help about our products.
Sometime it may happen that the software does not do what you want or expect.
Follow this steps if you run into a problem with processing lidar data:
- Check your (raw) data. Use lasvalidate to see if your input data is valid.
If your input data is not valid it is no big surprise that the result is not as expected.
- Check your program version.
Do you use the lastest version? If not, do so.
Do you use the latest version and you think this problem is new in this version: Try an older version!
It is may useful to run different versions in different directories.
See the changelog for the latest version number. Use “LAScopy -h” to see your version number.
Run all tools with the -v (verbose) option to see, if hey may generate a warning already.
- Define your problem.
Extract it. Keep it as small and simple as possible. Break it down.
Doing this the problem is may solved allready 😉
- See if others had this problem.
Use the search function with different keywords about your problem.
It is most likely that someone else had the same problem before.
- If you get this far and did not found a solution it is may worth to post your problem to the LAStools user group.
Again: Concentrate on the problem. Again: Break it down.
Supply some simple sample data so everyone can reproduce your problem.
List exactly the commands you did run.
What did they output?
What did you expect they do output?
Report the environment and version number you use.
This is an example of a good question.
