Crushed Rock Inter-Regional Flows

Derived from data collated from the 2005 Aggregate Minerals Survey, carried out by BGS for the Department for Communities and Local Government (CLG) which provide an in-depth and up-to-date understanding of regional and national sales, inter-regional flows, transportation, consumption and permitted reserves of primary aggregates for England and Wales. The information is used to monitor and develop policies for the supply of aggregates. This data set depicts the flow of crushed rock aggregate between the regions of England and Wales. The data originator also has similar data for sand and gravel and also the same data derived from the 1997 and 2001 Aggregate Minerals Surveys.

本数据集源自英国地质调查局（British Geological Survey, BGS）受英国社区与地方政府部（Department for Communities and Local Government, CLG）委托开展的2005年矿产骨料调查（Aggregate Minerals Survey）所整编的数据。该调查可为英格兰与威尔士地区原生骨料的区域及全国销量、区域间流动、运输、消费与许可储备量提供深入且最新的认知。相关信息可用于监测并制定骨料供应相关政策。本数据集刻画了英格兰与威尔士各区域间碎石骨料的流动情况。数据提供方还拥有针对砂石的同类数据集，以及源自1997年与2001年矿产骨料调查的同系列调研数据。
