The data acquisition occurred in 7 missions between March 31 and April 5, 2007 in Kent and New Castle Counties, Delaware.
The data have been classified and were flown to derive bare earth contours at 2 feet. Multiple returns were recorded for each laser
pulse along with an intensity value for each return. The points have a 1.4 m ground spacing (1.0 m ground spacing within the Wilmington
Urban Area).

This data set is an LAZ (compressed LAS) format file containing LIDAR point cloud data.
This LIDAR operation was designed to provide a high density set of masspoints within the defined areas. The data sets are
suitable for the development of contours for use in hydraulic/hydrologic model development, and for assessing environmental impacts.
Typical uses for the data set include: FEMA Flood Plain Map Modernization, DFIRM map updates, watersheds and other hydro studies per
FEMA specifications, county mapping projects which include several uses, in addition to flood mitigation assessment, mapping projects
that include accuracy verification, reporting and metadata.
We request that you credit the Sanborn Mapping Company when you use these data in a report, publication, or presentation.

Data Collection:
Using a Leica Systems ALS50 Light Detection and Ranging (LiDAR) system, flight lines of standard density ground spacing of 1.4 meter and
1.0 meter (within the Wilmington Urban Area) data were collected over areas in Kent County, DE (approximately 800 square miles) and New
Castle County, DE. Multiple returns were recorded for each laser pulse along with an intensity value for each return.
The data acquisition occurred in 7 missions between March 31, 2007 and April 5, 2007. During the LIDAR campaign, the Sanborn field crew
conducted a GPS field survey to establish final coordinates of the ground base stations for final processing of the base-remote
GPS solutions.

Airborne GPS Processing:
Airborne GPS data were differentially processed and integrated with the post processed IMU data to derive a smoothed best estimate
of trajectory (SBET). The SBET was used to reduce the LiDAR slant range measurements to a raw reflective surface for each flight line.
The overlap between flight lines was removed to provide a homogeneous coverage, and the coverage was classified to extract a bare
earth digital elevation model (DEM).
Airborne GPS is differentially processed using the GrafNAV V7.50 software by Waypoint Consulting of Calgary, Alberta, Canada.
The PDOP and distance separation are as follows:
IMU data is processed using the PosPac V4.2 software by Applanix Corporation of Richmond Hill, Ontario, Canada.
The reflective surface is derived using the ALS Post Processor software by Leica Geosystems GIS & Mapping Division of Atlanta, Georgia.
The classification and quality control (QC) of LiDAR data is carried out using TerraScan software by Terrasolid Limited of Helsinki, Finland.
2007-01-01T00:00:00
IMU data Processing:
IMU data provides information concerning roll, pitch and yaw of collection platform during collection event. IMU information allows
the pulse vector to be properly placed in 3D space allowing the distance from the aircraft reference point to be properly positioned
on the elevation model surface. IMU data is processed using the PosPac V4.2 software by Applanix Corporation of Richmond Hill, Ontario,
Canada.

Output LAS Files
The product output of LiDAR data is carried out using TerraScan software by Terrasolid Limited of Helsinki, Finland. LAS Binary and
ArcGIS shapefiles were created. The shapefiles represented the bare earth product. All data were tiles to be consistent with the
statewide orthoimagery tile layout. Two sets of data were provided -- one in ft (vertical) and the other in meters (vertical).
Both had meters horizontal units.
2008-01-01T00:00:00
The NOAA Office for Coastal Management (OCM) received files in LAS format. The files contained LiDAR intensity
and elevation measurements. OCM 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.

The vertical values in this data set have been converted to reference North American Vertical Datum of 1988 (NAVD88) (GEOID18) meters, using the GEOID18 grids provided by the National Geodetic Survey.
Any datum and projection transformations were then done with the Office for Coastal Management 'datum_shift' program. Compression to an LAZ file was done with the LAStools 'laszip' program and can be unzipped with the same free program (laszip.org)
