Description 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 . ELVIS allows the user to search available elevation data across Australia and download tiles containing either classified point clouds or Digital Terrain Models. As new data becomes available, they will also be uploaded and be made available for download via ELVIS. The layer contains attribute information including extent, grid spacing, year of acquisition, source, average point density, accuracy (horizontal and vertical), available projections, any licensing restrictions and availability on ELVIS.
