Reading binary Lidar file
Aug 11th, 2009, 7:53am
 
Good morning everyone,

I like to visualize some lidar data using processing. The input file would be a binary file with the LAS standard format.
I was wondering how I can could read such file using processing ?
Thanks in advance.

Best Regards.
Shadowing

i did some googling using 'lidar las file format'...

this is a link to the pdf of the  file format specification:
http://www.asprs.org/society/committees/standards/lidar_exchange_format.html

you will need to create your own LAS file reader by parsing the bytes of the file, and translating it into the info you need,  as per the spec.

here is some java software possibilities, after googling 'java lidar las library':

http://www.freegis.org/database/?cat=72

liblas is the c++ implementation. it might be helpful to d/l the source and read how it reads the file bytes for your own java implementation...
