GSWA Pingaring uranium grid geodetic

This GSWA Pingaring uranium grid geodetic is an airborne-derived radiometric uranium window countrate grid for the Pingaring, WA,1993 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 GSWA Pingaring uranium grid geodetic has a cell size of 0.00083 degrees (approximately 85m). The data are in units of counts per second (or cps). The data used to produce this grid was acquired in 1993 by the WA Government, and consisted of 7622 line-kilometres of data at 400m line spacing and 60m terrain clearance.

本GSWA（Geological Survey of Western Australia，西澳大利亚地质调查局）平加林铀大地测量格网数据集，是基于1993年西澳平加林地区航空测量获取的放射性铀能窗计数率格网数据构建而成。放射性测量，亦称伽马射线能谱测量方法，可探测地球表面附近的伽马射线自然变化，该变化源于钾（K）、铀（U）与钍（Th）的自然放射性衰变。所采集的数据将通过标准流程进行处理，以确保记录的响应仅源于地下岩石的放射性信号。经处理后得到的数据集可通过解译揭示地下地质构造。处理后的数据将由GA地球物理学家开展质量核查，以确保GA发布的最终数据符合使用需求。本GSWA平加林铀大地测量格网的格网单元尺寸为0.00083度（约85米）。该数据的单位为每秒计数（counts per second，简称cps）。用于生成该格网的数据由西澳大利亚州政府于1993年采集，数据覆盖7622线公里，测线间距为400米，飞行离地高度为60米。
