MGA Zone: MGA Zone 55
Device Name: Optech Orion and Optech Gemini
Pulse Rate Frequency: 100 kHz
Laser Returns: 1st, 2nd, 3rd and Last
Average Point Density (per Sq m): 3
Spatial Accuracy Horizontal: 0.80m
Spatial Accuracy Vertical: 0.30m
Classification Type: C3
Limitations of the Data: Accuracy specifications (95% CI) meet ICSM Guidelines for Digital Elevation Data

Digital Elevation Model (DEM):
The DEM is produced using TIN (Triangular Irregular Network) method of averaging ground heights to formulate a regular grid. This data set contains the ground surface model derived from the point cloud (Class 2 - Ground) and is not fully developed with regard to hydrological data.
