GSNSW Exploration NSW Area D Surat Basin uranium grid geodetic

This GSNSW Exploration NSW Area D Surat Basin uranium grid geodetic is an airborne-derived radiometric uranium window countrate grid for the NSW DMR, Discovery 2000,1994-95, Area D, Surat Basin 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 D Surat Basin uranium grid geodetic has a cell size of 0.00072 degrees (approximately 75m). 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 117000 line-kilometres of data at 400m line spacing and 80m terrain clearance.本数据集为GSNSW勘探项目新南威尔士州D区块苏拉特盆地铀测地网格，是针对新南威尔士州矿产资源部（NSW DMR）1994-1995年苏拉特盆地D区块"Discovery 2000"勘探测量生成的机载辐射测量铀窗口计数率网格。 辐射测量（或称伽马能谱）法通过探测地表附近的伽马射线自然变化，来反映钾（K）、铀（U）和钍（Th）的自然放射性衰变特征。采集所得数据经标准流程处理，确保记录的响应仅源于地下岩石。经处理的数据集可用于解译地下地质构造。GA的地球物理学家会对经处理的数据开展质量核查，以确保GA发布的最终数据符合使用要求。 本铀测地网格的像元尺寸为0.00072度（约75米），数据单位为每秒计数（cps）。本数据集所用数据由新南威尔士州政府于1995年采集，包含117000测线公里的实测数据，测线间距为400米，飞行离地高度为80米。
