Process Steps

Process Step 1

CC ID: 1132794
Description:

NGS processed in field.

NOAA Cessna Citation

Acquired in April 2004

Optech ALTM 2050 system

4,000 ft AGL

~1-2 m post spacing

Nav data was from an Applanix POS processed with the POSPAC software

Laser data processed with Optech's REALM software.

LAS files generated with LAStools

Process Date/Time: 2004-04-01 00:00:00

Process Step 2

CC ID: 1132795
Description:

The NOAA Office for Coastal Management (OCM) received the files in LAS format. The data were in UTM zone 10.

OCM performed the following processing to the data to make it available within Digital Coast:

1. The data were classified using LASEdit

2. The data were converted from UTM coordinates to geographic coordinates.

3. The LAS data were sorted by latitude and the headers were updated.

4. The data were filtered to remove outliers.
