GSNSW Exploration NSW Area A4 Koonenberry uranium grid geodetic

This GSNSW Exploration NSW Area A4 Koonenberry uranium grid geodetic is an airborne-derived radiometric uranium window countrate grid for the NSW DMR, Discovery 2000, 1994-95, AREA A4, Koonenberry survey. The radiometric, or gamma-ray spectrometric method, measures the natural variations in the gamma-rays detected near the Earth's surface as the result of the natural radioactive decay of uranium (K), uranium (U) and uranium (Th). 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 GSNSW Exploration NSW Area A4 Koonenberry uranium grid geodetic has a cell size of 0.00063 degrees (approximately 65m). The data are in units of counts per second (or cps). The data used to produce this grid was acquired in 1995 by the NSW Government, and consisted of 67000 line-kilometres of data at 250m line spacing and 60m terrain clearance.

本数据集为GSNSW（新南威尔士州地质调查局）勘探项目新南威尔士州A4区库嫩伯里铀大地格网，是为新南威尔士州矿产资源部（NSW DMR）“Discovery 2000”项目（1994-1995年）的库嫩伯里测量任务制作的航空衍生放射性铀窗口计数率网格。放射性测量（或称伽马射线能谱测量）方法可检测地表附近因钾（K）、铀（U）与钍（Th）自然放射性衰变产生的伽马射线自然变化。采集的数据将通过标准流程进行处理，确保记录的响应仅源于地下岩石。处理后生成的数据集可用于解译以揭示地下地质构造。经处理的数据会由GA（澳大利亚地质调查局）的地球物理学家开展质量核查，确保GA发布的最终数据符合使用需求。
本数据集的格网单元尺寸为0.00063度（约65米），数据单位为每秒计数（cps）。本数据集所用的原始数据由新南威尔士州政府于1995年采集，涵盖67000线公里的测线数据，测线间距为250米，飞行离地高度为60米。
