| * » Abstract |
The data were acquired in March 2005 using the NASA Experimental Advanced Airborne Research Lidar (EAARL) platform in Sussex County, Delaware. Once acquired, the data were processed by USGS personnel into both 2-foot contours and digital elevation models. Multiple returns were recorded for each laser pulse. This is a bare earth data set. The points have approximately a 3 m ground spacing. Water points remain in the bare earth data set, they have not been classified as water.

| * Purpose |
The Sussex County dataset was created to provide elevation based data to use for modeling and mapping. |

| Data Set Credit | The Sussex County dataset was created in a joint effort between the Delaware Geological Survey and the U.S. Geological Survey. While there are no constraints on the use of this data, the DGS and USGS would appreciate mention as the originators if others use these data.

| » Description |
Data were collected by NASA EAARL (Experimental Advanced Airborne Lidar) during March of 2005. Flying was done out of Salisbury, Maryland. Nominal post spacing was approximately 3 meters, with data denser in areas of flight line overlap. A GPS base station was established and operated for 1 hour prior to, during, and for at least 30 minutes after completion of data collection flights (take off to touch down). The GPS collected data at 1 Hz intervals. GPS data were used for aircraft location correction. Lidar data collected for cross tracks were flown during each data collection flight. Preliminary fundamental vertical accuracy testing was performed against data collected by NRCS surveyors. Three landuse classes were tested woods, roads, and farm lanes with the aggregate average RMSe being 0.102m and the greatest RMSe observed was 0.148m. Processing was done in Airborne Lidar Processing Software (ALPS) by USGS personnel in Reston VA. Final bare-earth point data inspection and clean up was manually performed by USGS personnel in Dover Delaware and Baltimore, MD using ArcMap. |

The NOAA Office for Coastal Management (OCM) received the data in shapefile format with x, y, and z. The x, y, and z values were extracted from the shapefiles and converted to ASCII formatted text using a processing loop in arc/info. The ASCII files were then converted to LAS format using an internal processing script. OCM then performed the following processing on the data to make it available within the Digital Coast: 1. The data were converted from State Plane coordinates to geographic coordinates. 2. The data were converted from orthometric to ellipsoid heights using Geoid03. 3. The LAS header fields were sorted by latitude and updated. 4. The data were filtered to eliminate outliers. |
