通过对学术文献和英国地质勘探局测绘的回顾，制作了与上一次(德文西亚)不列颠冰盖有关的冰川地图和伴随的地理信息系统(GIS)数据库。地图(1：625000)包含在文件夹中，地理信息系统数据可通过Web下载(http:www.shef.ac.ukgeographystaffclark_chrisbritice.html).免费获取重点放在限制最后一次冰盖的信息上。包括：冰川、冰川、冰层、融水渠道、隧道峡谷、剪切线、关键冰川沉积的界限、冰湖沉积、冰堰湖、不稳定的扩散模式、陆架边缘扇和主冰帽的洛蒙德湖再推进界限。该地理信息系统包含20,000多个分为专题层的要素(如上所述)。对各个功能进行属性，以便可以追溯到其已发布的来源。鉴于支撑这项工作的已公布信息来源是经过150年的零碎努力得出的，因此我们的主要警告是数据的一致性和可靠性。希望这一汇编将促进对已公布数据的更严格审查，有助于古冰川重建，并促进在数值冰盖模拟中使用现场证据。它还可能有助于指导现场工作人员未来的调查。
A review of the academic literature and British Geological Survey mapping is employed to produce a ‘Glacial Map’, and accompanying geographic information system (GIS) database, of features related to the last (Devensian) British Ice Sheet. The map (1:625000) is included in a folder and GIS data are freely available by web download (http:www.shef.ac.ukgeographystaffclark_chrisbritice.html). Emphasis is on information that constrains the last ice sheet. The following are included: moraines, eskers, drumlins, meltwater channels, tunnel valleys, trimlines, limit of key glacigenic deposits, glaciolacustrine deposits, ice‐dammed lakes, erratic dispersal patterns, shelf‐edge fans and the Loch Lomond Readvance limit of the main ice cap. The GIS contains over 20 000 features split into thematic layers (as above). Individual features are attributed such that they can be traced back to their published sources. Given that the published sources of information that underpin this work were derived by piecemeal effort over 150 years, then our main caveat is of data consistency and reliability. It is hoped that this compilation will stimulate greater scrutiny of published data, assist in palaeoglaciological reconstructions and facilitate use of field evidence in numerical ice‐sheet modelling. It may also help direct field workers in their future investigations.
