The data contained in these files contain topographic data collected by the CHARTS system along the northern coast of Hawaii (Big Island), Kauai, Maui, Molokai, and Oahu in the state of Hawaii. The data were collected on the following dates:
Hawaii (Big Island): 20070123-20070210
Kauai: 20070112-20070210
Maui: 20070111-20070127
Molokai: 20070111-20070127
Oahu: 20070112-20070210
The data points representing bare earth have been classified as such using TerraScan with results provided in the classified las files. Classification value "1" means "Unclassified" and a value "2" means "Ground." The data were collected and processed in geographic coordinates and ellipsoid heights. The positions are relative to NAD83 HARN in decimal degrees of longitude and latitude. The heights were converted from ellipsoid to geoid (NAVD88) heights using the Geoid03 model with the results in meters. These heights were then adjusted to Mean Sea Level.
This data set is an LAZ (compressed LAS) format file containing LIDAR point cloud data.
