Changes in version 2.0

1. Points with no data were removed from the LooeKey_IntersectPoints SHP file using the "Select by Attribute" tool to select points from the attribute table where the RASTERVALU (multibeam) or the RASTERVA_1 (lidar) equaled -9999. Then the "Editor Toolbox" was used to delete a total of 2,548 points, creating the LooeKey_IntersectPoints_v2 SHP file.

2. The elevation and volume statistics were recalculated using the updated LooeKey_IntersectPoints_v2 SHP file, creating the LooeKey_Elevation_Statistics_v2.csv and LooeKey_Volume_Statistics_v2.csv.
