Getech UKCS Multi-Satellite Gravity Data

<span><p align='JUSTIFY'>Getech’s Multi-Satellite Gravity data was purchased with publication rights by the NSTA as part of the Data Purchase tender process (TRN097012017) that was carried out during Q1 2017. The Getech Multi-Satellite data provides a high resolution, consistent gravity dataset for the whole of the offshore UKCS area. The data is being published in the interest of making additional sources of data openly available for use by the wider industry and academic communities in support of ongoing and future exploration activity.</p> <p align='JUSTIFY'></p> <p align='JUSTIFY'>The outputs as published here include a technical summary of the Multi-Sat data and description of the data products (PDF format), all of the grids provided to the NSTA in PDF, ASCII, ESRI and GEOSOFT formats and an ArcGIS project containing all of the data provided. NSTA web feature services (WFSs) have been included in the map document in this delivery. They replace the use of a shapefile or feature class to represent block, licence and quadrant data. By using a WFS, the data is automatically updated when it becomes available via the NSTA.</p> <p align='JUSTIFY'>All releases included in the Data Purchase tender process that have been made openly available are summarised in a mapping application available from the NSTA website. The application includes an area of interest outline for each of the products and an overview of which wellbores have been included in the products.</p></span>本数据集为Getech公司的多卫星重力数据（Multi-Satellite Gravity Data），由NSTA于2017年第一季度开展的TRN097012017号数据采购招标流程中购得，并附带合法发布权限。该套Getech多卫星重力数据可为整个英国大陆架（United Kingdom Continental Shelf, UKCS）近海海域提供一套高分辨率、一致性优异的重力数据集。本次公开发布该数据，旨在为广大工业界与学术共同体开放额外的数据来源，以支撑当前及未来的油气勘探活动。 本次发布的成果包含多卫星重力数据的技术摘要与数据产品说明文档（PDF格式）、以PDF、ASCII、ESRI及GEOSOFT格式交付给NSTA的全部网格数据，以及包含所有交付数据的ArcGIS项目文件。本次交付的地图文档中已集成NSTA网络要素服务（Web Feature Services, WFSs），其替代了原本用于表示区块、许可证及象限数据的shapefile与feature class。通过调用WFS，数据可在NSTA更新数据源后自动同步更新。 所有在数据采购招标流程中公开发布的成果，均可通过NSTA官网的制图应用查阅汇总信息。该应用提供了各数据产品的感兴趣区域轮廓，以及各产品所包含的井筒概况。
