Edited 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.

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 'edited' to the extent that they have been largely reduced to a 'bare ground' representation; most above ground level features and objects such as buildings and trees have been removed from 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 (scp_3009202ne.csv) in ASCII format.

Purpose:
These data are used for the production of Triangulated Irregular Network (TIN) digital elevation models or whenever a direct representation of the bare-earth LIDAR point data is needed.
Supplemental_Information:
The metadata for this image are encapsulated into several documents. The metadata are not complete if you did not receive the following files along with the data set:

Data_Quality_Information:
Logical_Consistency_Report:
Inspection of these data reveals that some residual points from trees (especially on slopes) are present in the data.
Completeness_Report:
The data set includes only those data remaining for a 'bare earth' representation and that have not been otherwise eliminated as part of edit processing. These data consist of approximately 70% of the data originally present in the raw data set, raw_3009202ne.
