Collect and deliver high-density elevation point data derived from multiple-return light detection and ranging (LiDAR) measurements for use in supporting topographic analysis, including applications such as flood plain mapping. The data will be delivered as LiDAR Bare Earth within the areas designated in areas of Madison and Eastern Yazoo Counties to aid in visual interpretation of Flood Basin elevations and for addition to the MDEM elevation dataset. All data will comply with mapping guidelines and specifications as stated in the FEMA Procedure Memorandum No.61.Atlantic Group will provide LiDAR products to support MDEQ in supporting solutions for a variety of purposes including updating DFIRM maps, hydrologic modeling, transportation routing, floodplain mapping and assessment of natural hazards. Furthermore, the data sets can be utilized by the general public including engineers, surveyors, appraisers and others interested parties to evaluate transportation and land use planning.

Horizontal accuracy is computed using the formula RMSE (z) x 1.7308: 1-inch = 100 feet equivalent (Accuracy = 2.2 feet or 0.67 meters) as defined by the “ASPRS Guidelines: Accuracy Reporting for topographic Data.” This guideline implements the National Standard for Spatial Data Accuracy (NSSDA) for testing of topographic data.

Fundamental Vertical Accuracy (FVA) testing will be assessed by using checkpoints in open terrain. FVA is calculated at the 95% confidence level using RMSEz x 1.9600. Utilizing an Optech 3100 multi-return system, Light Detection and Ranging (LiDAR) data will be collected to support the generation of a high-resolution point-cloud. The system consists of geodetic GPS positioning (AGPS), orientation derived from high-end inertial sensors (IMU), and a high-accuracy laser. The sensor is attached to the aircraft’s underside and emits rapid pulses of light that are used to determine distances between the plane and terrain below. LIDAR data will be processed to yield a ground surface (Bare Earth). LAS formatted data will be delivered to MDEQ/Geology classified as bare earth as well as above ground points.
