ELVIS Digital Elevation Model Imagery Catalog

The Digital Elevation Model Imagery Catalog layer describes precision elevation datasets acquired from LiDAR and aerial / satellite sensors currently archived in the department. Precision elevation products are defined as Digital Terrain Models (or bare Earth Digital Elevation Models) captured from either LiDAR sources or photogrammetrically derived from aerial photography. LiDAR classified point clouds and derived Digital Terrain Models under a CC-BY license have been uploaded to the ELVIS Elevation and Depth Online Portal (https://elevation.fsdf.org.au/).

数字高程模型影像目录图层（Digital Elevation Model Imagery Catalog layer）描述了本部门当前存档的、由激光雷达（LiDAR）及航空/卫星传感器采集得到的高精度高程数据集。高精度高程产品被定义为数字地形模型（Digital Terrain Models，又称裸地数字高程模型），其既可通过激光雷达数据源获取，也可由航空摄影经摄影测量方法衍生得到。目前，采用知识共享署名（CC-BY）许可协议的激光雷达分类点云及其衍生数字地形模型，已上传至ELVIS高程与深度在线门户网站（https://elevation.fsdf.org.au/）。
