Map based index (GeoIndex) UTM (Universal Transverse Mercator) series 1:250000 Geological Maps

This layer of the Map based index (GeoIndex) shows the location of available UTM (Universal Transverse Mercator) series 1:250000 geological maps. These maps display Bedrock, Quaternary (Superficial deposits) geology of the offshore areas and Seabed Sediments of the UK landmass and offshore regions. The different versions are normally published as separate maps for land areas, but these may be combined on a single map for offshore areas. Maps are normally available in flat and folded format. The UTM Series (Universal Transverse Mercator projection) maps cover an area of 1deg. latitude by 2deg. longitude.本基于地图的索引（GeoIndex）图层展示了可用的通用横轴墨卡托（Universal Transverse Mercator，简称UTM）系列1:250000比例尺地质图的分布点位。此类地图涵盖近海海域的基岩、第四系（松散堆积物）地质情况，以及英国本土及近海区域的海底沉积物分布。不同版本通常针对陆地区域以单幅独立地图形式发布，而针对近海区域的版本可整合为单幅地图。地图通常提供平装与折叠两种版式。该UTM系列地图的覆盖范围为纬度1度、经度2度的矩形区域。
