- Description
- Acquisition: Airborne LiDAR data was acquired from a fixed wing aircraft on the 7th of January 2017. Ground Support: Base station support was provided SmartNet Aus. Previosuly surveyed Reference Points acquired by AAM, plus previous LiDAR data allowed an assessment of the accuracy of the ALS data. Data Processing: Reduction of the LiDAR data proceeded without any problems, Laser strikes were classified into ground and non-ground points using a single algorithm across the project area. Manual checking and editing of the data classification further improved the quality of the terrain model. Further Processing: ArcGIS 9.2 Terrain Grids were derived using the Natural Neighbor interpolation. This method uses the closest triangles and applies weights to the proportionate areas from the grid cell centroid to interpolate the value. It uses known elevation data, it does not make any predictions regarding the surface and accurately depicts existing troughs and peaks in the data and supports irregular point spacing, which suits the nature LiDAR data. The contours supplied are designated ¿ENGINEERING CONTOURS¿ only. They are compiled from a rigorous triangulation of the supplied data. No cartographic licence has been applied. They are intended to provide a visual representation of the terrain data, and are not suitable to be used as a cartographic map.
