Title: 2006 Federal Emergency Management Agency (FEMA) Lidar: Nueces County, Texas
Short Name: tx2006_nueces_m548_metadata
Status: Completed
Publication Date: 2006-12-21
Abstract:

Spectrum Mapping, LLC was tasked by MAPVI - URS Corporation, Albuquergue, to provide airborne Light Detection and Ranging (Lidar)

of approximately 620 square miles around Nueces County, Texas. MAPVI (Mapping Alliance Partnership VI for FEMA Region IV) is a

joint venture of URS Corporation, Greenhorne & O'Mara and Spectrum Mapping. Spectrum followed data collection and processing

procedures for Federal Emergency Management Agency (FEMA) Guidelines and Specifications Appendix A.

Data product deliverables included Lidar to support 2 foot contours. Spectrum's acquisition division collected the Lidar data

on June 19, 22-25, 27, 28 and July 16 and 17, 2006. The project was collected with a Rams ALS50 Lidar sensor, including an

inertial measurement unit (IMU) and a dual frequency Global Positioning System (GPS) receiver and antenna.

Upon receipt of this data, the NOAA Coastal Serices Center reclassified all non-ground data to a classification of 1 (Unclassified)

and all ground points to a classification of 2 (Ground).

Purpose:

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, and flood mitigation assessment.

Process Step 2

CC ID: 1138861
Description:

The NOAA Office for Coastal Management (OCM) received the files in las format. The files contained Lidar elevation and intensity

measurements. The data was in Texas State Plane coordinates - South (FIPS Zone 4205), NAD83 and NAVD88 Geoid 03 vertical datum

and US Survey Feet. OCM performed the following processing to the data to make it available within the Digital Coast:

1. The data were converted from Texas State Plane coordinates to geographic coordinates.

2. The data were converted from NAVD88 (orthometric) heights to GRS80 (ellipsoid) heights using Geoid 03.

3. The data were converted from US Survey feet to meters.

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

5. All non-ground data reclassified to a classification of 1 (Unclassified) and all ground points reclassified to a classification

of 2 (Ground).
