    Gravity data measures small changes in gravity due to changes in the density of rocks beneath the Earth's surface. The data collected are processed via standard methods to ensure the response recorded is that due only to the rocks in the ground. The results produce datasets that can be interpreted to reveal the geological structure of the sub-surface. The processed data is checked for quality by GA geophysicists to ensure that the final data released by GA are fit-for-purpose. This Great Lake Region Gravity (P196250) contains a total of 223 point data values acquired at a spacing of 1250 metres. The data is located in TAS and were acquired in 1962, under project No. 196250 for University of Tasmania.

  • This document details the methods and results of the project Adelaide LiDAR Classification and Derived Products¿ performed by RPS for Geoscience Australia in 2013. Lineage and Accuracy Statements for ANZLIC metadata documents for each of the project deliverables are included. Airborne LiDAR data was acquired over Adelaide in September 2008 and North Adelaide in September 2011. Differences in the level of classification reduced the ability to integrate the data into an accurate, seamless and consistent coastal DEM suitable for detailed modelling the potential impacts of coastal inundation or riverine flooding. The objective of this project was to reclassify both the 2008 and 2011 point clouds to ICSM Level 3 and derive hydro flattened 1m bare earth DEMs and; 0.25m cartographic contours, all inline with the ICSM LiDAR Acquisition Specifications. Figure 1. Adelaide LiDAR Reclassification 2012 overview map The LiDAR The LiDAR was provided as tiled LAS files. RPS did not apply any vertical or horizontal adjustments to the LiDAR and is unable to comment on the spatial accuracy of the point cloud. The deliverables were: Classified ICSM Level 2 and Level 3 point clouds in LAS format 1 metre DEMs in ESRI Binary grid format 0.25 metre contours in ESRI Shape format Break lines in ESRI Shape format. This report All files were named according to the ICSM file naming specifications.
