UIS Mapping Grades

For the last decades, a grading system originally installed by the British Cave Research Association (BCRA) helped to assess the precision of cave maps and related data. Although the BCRA grades were spread
over the globe and often used internationally, they were never officially recognized by the International Union of Speleology (UIS). The fact that BCRA revised the grades several times, but that these upgrades
did not necessarily make it to the international users, did not help to avoid confusion. Therefore, several national federations such as the Australian Speleological Federation (ASF) made up their own grading
system, largely based on the BCRA input, but with notable changes. In order to clarify the situation, the UISIC’s working group «Survey and mapping» reviewed the present grading systems in order to get an
official UIS grading system under way. The paper presents these UIS mapping grades. At the 15th International Congress of Speleology in Kerrville (USA), the working group discussed the BCRA and ASF mapping grades, their use, limitations, and possible upgrades for international use within the UIS. The vast majority of the people present agreed that the use of a grading system in speleological mapping was needed in order to inform the map user of the expected accuracy of the map. After a lively discussion, it was seen that the current ASF standards quite closely match the expectations of the group and that they could be upgraded for UIS use. The following tables present the grades, the accuracy of details, additional information, and an explanation which helps to understand the meaning of the tables. The present version was voted by the UIS national delegates in summer 2010 and is therefore officially in use now. The present note uses some brand names for easier understanding of the type of device. In no means,
this is meant to be a support for these devices; it merely uses that name to describe the functioning principle.Technical Note.
