LIDAR QA/QC Reports Are Available
Each LIDAR panel belongs to one of fifty-five task areas that cover the land areas of the state of Louisiana. Each task area has a review file and an appendix file which should be used as a reference for any Quality Assurance/Quality Control (QA/QC) questions regarding the LIDAR data. These files are now available for downloading through the LIDAR downloader. For each individual LIDAR tile, the downloader will display a link for downloading the corresponding task area's QA/QC reports along with the links for downloading the contours, breaklines, DEM, and points for that tile. To go to the LIDAR Downloader, click here.

LIDAR Coverage is Complete
The remaining outstanding LIDAR panels have now been added to Atlas!

LIDAR Panels Quartered Yet Again
Deliveries of the LIDAR data to Atlas have traditionally been in quarter quadrangle (3.75-minutes latitude by 3.75-minutes longitude) format. A number of the panels in this last delivery were further subdivided into quarter-quarter quadrangles (1.875-minutes latitude by 1.875-minutes longitude) due to increased point density. In order to continue to use the same name and index as the previous LIDAR panels, all four quarters of this latest subdivision are grouped together into one Winzip archive. In other words, there are now four files that cover the normal 3.75-minute quarter quadrangle, and all four files are packaged together into the same Winzip file.

  Newest LIDAR has Breakline and 3d Contours
The latest LIDAR data also has breakline data in shapefile format. The LIDAR downloader will allow the downloading of breaklines in addition to the contours, DEMs, raw points, and edited points. The contour data, while caring an attribute with the elevation in feet in the shapefile, has been processed so that the z coordinates of the contour lines reflect the elevation in meters. Only the latest panels have the breakline and 3d contours data. The previously available panels will be reprocessed to include breakline data and contours with true z coordinates.

LIDAR Point Data Available for Downloading
LIDAR evelation data can come in different forms. Two forms, Digital Elevation Models (DEM) and contours, have been available on Atlas. These two forms were generated from elevation samples represented as point data (X, Y, and Z). This point data is known as edited or veg-off point data because it is a set of points that represent the elevations of the bare earth, ie, without vegetation, man-made structures, etc. The edited point data was itself generated from another set of points called raw or unmodified or veg-on point data. The raw points represent elevation sampling as recorded by the LIDAR device. Obstructions such as tree canopy and road overpasses will be included in this point data. Atlas now has both the raw and edited point data sets for downloading in addition to the DEM and contour forms of this data. Use the Atlas LIDAR downloader to download the point data in the same way as with the contours and DEM data.

DRG Access Resumes/Trimmed 7.5' Quads Online
During the time when the 7.5' DRGs (scanned topographic maps) were not available, the trimmed versions of the DRGs were readied for downloading. These files are now accessible via the 1:24,000 Scanned Topographic Maps. These files have the margins with the marginalia trimmed away. There is only a small amount of "white space" on the edges of the maps. This space is necessary as the quads are stored in files with a raster format with is basically a matrix. Each row of the matrix must have the same number of columns whether or not there is data for these columns. However, the quads are not perfect rectangles due to the curvature of the earth. Therefore, there is a small amount of space on the edges of maps; this space is used to "square off" the map so that it fits within the matrix of the file.

The files are geotiff files. The ASCII world file (.tfw) has not been omitted since current versions of most GIS do not require it. If you need the world files for correct placement of the DRG on the earth's surface, please contact the webmaster.
