The Classified LAS file
• CZMIL (Full waveform vs. discreet returns)– Up to 31 returns per each of the 9 channels.
• Changed return number of any return past second and before the second to last return to 3rd return. A 9 return file would have return numbers 1,2,3,3,3,3,3,4,5
BUILDING STRONG®
The Classified LAS file
• Use of scalable tile schemes such as the MGRS/USNG• Set projections via batch using Vdatum • Classes are 1,2, and 29
– Changed to be able to be read in most programs– More changes in the future with the rollout of LAS 1.4.

The Classified LAS file
• Speed of processing– Limit I/O– Batch scripts

Digital Terrain Models and Digital Elevation Models
Challenges• Exact cell size and location
from survey year to survey year
• Quick creation of tiffs with the correct projection defined
• Quick creation of metadata files in more than one format
Solutions• Create TIN’s in QT modeler
then covert to ESRI based .asc.
• Created a phython script to use the ASCIItoRaster tool and other processes.
• Created a phython script to batch create the metadata based off of a template and shapefile.
