Hey! I'm Greg Ahlswede, an American orienteering living in Spain. I live with Manuel Jurado. He's been showing me how to use Kartapullautin. Really great stuff. Thank you!

I've been trying to create maps in my home state of Pennsylvania so the clubs there have maps to train on. However, the program doesn't generate a map with the data provided by Pennsylvania. It always runs out of memory even if it is a very small file (<8kb). Manuel isn't sure what the problem is either.

I could send a few screenshots I took of the errors that occur during map generation if that would provide a clearer explanation. Or if you could look at the data I'm working with I would be very grateful.

Maybe your data is in feet or surveyfeet and not in meters. It should be meters. Check that first, and convert it to meters, command example here:

I think I have experimented with Pennsylvania data some time ago, but I can't remember was there any issues, like having to re-classify the data or something.

But you can drop me a link to one of the tiles you are working with and I'll try to take a look.

Alright. I tried changing it from survey feet to meters in las2las, but I think I only managed to change it in the header. At any rate, I'm thoroughly confused.

If you could take a look at the data and point me in the right direction I'd appreciate it.

This is the data that I tried to change to meters.

This data from another area of PA that I classified, but never attempted changing from survey feet to meters.

Thanks man!

I gave it the cedarcreek's command, and processed it with pullautin in 1x1 km tiles (tiles made with lastile). The other file could not be processed, x y coordinates are zeroed.

Whew, finally figured it out. Had to convert it to sp 83 and meters. Let's see if I can map some cool areas. Thanks!
