Watershed Concepts 2003 This is a point dataset of elevations over the SW quadrant of the Lake Charles Southeast 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: Calcasieu Parish, Louisiana under the Watershed Concepts contract number EMT-2002-CO-0048, Task Order 012. The data are provided as a comma delimited xyz file (scp_3009364sw.csv) in ASCII format. 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. 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: >scp_3009364sw.mtd - this metadata in mp (metadata parser) compatible ASCII text form >scp_3009364sw.html - this metadata in HTML form >scp_3009364sw_faq.html - this metadata presented as Questions and Answers >scp_3009364sw.sgml - this metadata in SGML form >scp_3009364sw.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. 200202 Approximate date of LIDAR survey used to build the source data for this data set complete none planned -90.5625 -90.5000 +30.9375 +30.8750 none framework LIDAR elevation None Louisiana Calcasieu Parish none These unaltered data may not be redistributed without all of the elements of the metadata listed in the Supplemental_Information section of this metadata document.

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_3009364sw.
