Raw LIDAR Elevation Data, NE quadrant of Steep Gully quadrangle, Louisiana, UTM 15 NAD83, Louisiana Federal Emergency Management Agency (FEMA) Project - Phase 2 of Louisiana LIDAR Data Development: Rapides Parish, Louisiana under the Watershed Concepts contract number EMT-2002-CO-0048, Task Order 013. [raw_3009202ne.csv]

Description:

Abstract:

This is a point dataset of elevations over the NE quadrant of the Steep Gully quadrangle, Louisiana. The data were derived from LIDAR measurements performed in 2002. The data are 'raw' to the extent that they have not been reduced to a 'bare ground' representation; above ground-level features and objects such as buildings and trees are still present in these data.

These data were produced for the Louisiana Federal Emergency Management Agency (FEMA) Project - Phase 2 of Louisisana LIDAR Data Development: Rapides Parish, Louisiana under the Watershed Concepts contract number EMT-2002-CO-0048, Task Order 013.

The data are provided as a comma delimited xyz file (raw_3009202ne.csv) in ASCII format.

Purpose:

These data are the starting point for the production of 'bare-ground' digital elevation models.

Supplemental_Information:

The metadata for these data are encapsulated into several documents. The metadata are not complete if you did not receive the following files along with the data set:

raw_3009202ne.mtd - this metadata in mp (metadata parser) compatible ASCII text form
raw_3009202ne.html - this metadata in HTML form
raw_3009202ne_faq.html - this metadata presented as Questions and Answers
raw_3009202ne.sgml - this metadata in SGML form
raw_3009202ne.xml - this metadata in XML form

The information depicted on this map represents the results of the survey on the dates indicated and can only be considered as indicating the general conditions existing at the time.

Data_Quality_Information:

Logical_Consistency_Report:

These data have been checked and adjusted against ground control elevation points.

Completeness_Report:

The data set includes all the LIDAR data obtained over the 3.75 minute cell area except in those areas where multiple flight lines had overlap. In these areas, only the data from the flight yielding data closest to nadir were retained for this data set.

Lineage:

Process_Step:

Process_Description:

Raw LIDAR data from flights covering the area were seamed to remove overlap areas, corrected to local ground control, and calculated to NAVD88 elevations using Corpscon.
