Wax Lake Delta, Louisiana, USA 2013

Airborne lidar data of Wax Lake Delta, Louisiana, USA, a delta prograding into Atchafalaya Bay, Gulf of Mexico. Rasters were produced from the 2013 Airborne lidar data wherein trees and vegetation were removed. The data were then rasterized and saved to geotiff using the software package CloudCompare. <br><br> Note: The point cloud data were not initially classified for vegetation removal. As such, the investigators removed vegetation to create the raster datasets. The removal process will not match the removal from the classification performed on the data later. The later classification is uploaded to OpenTopography. To get the same rasters as the ones available on OpenTopography, start with the complete unclassified point cloud and follow the methods described in the <a href="https://cloud.sdsc.edu/v1/AUTH_opentopography/www/metadata/WLD_2013_metadata.zip">full metadata</a> file.

美国路易斯安那州瓦克斯湖三角洲的机载激光雷达数据，该三角洲向墨西哥湾的阿查法拉亚湾推进。数据集源自2013年的机载激光雷达数据，其中已去除树木和植被。数据随后通过CloudCompare软件包进行栅格化处理，并以GeoTIFF格式保存。注：点云数据最初并未进行植被分类以进行去除。因此，研究者在创建栅格数据集时手动去除植被，此过程与后期对数据进行分类时采用的去除方式可能存在差异。后期分类数据已上传至OpenTopography。若要获取与OpenTopography上相同的栅格数据，需从完整的未分类点云数据开始，并遵循《<a href="https://cloud.sdsc.edu/v1/AUTH_opentopography/www/metadata/WLD_2013_metadata.zip">完整元数据</a>》文件中描述的方法进行。
