This subdirectory contains survex data files for the connected components of the Lancaster Hole / Easegill / Pippikin Pot system.
These have been modified from the originals in the Cave Registry Data
Archive so that the individual caves now break at the cave
descriptions in the new edition of Northern Caves, and duplicate /
splay legs have been identified and flagged. This means that cave
lengths can be computed automatically. A complete list of these
changes (which affect the claimed length of the system) is given in
duplicates.dat.
For convenience the cave statistics generated by running the
Makefile in unixtools against this data set have been
imported into the spreadsheet Easegill-Pippikin_statistics.ods.
The dataset is georeferenced at the top level in
Easegill-Pippikin.svx to the OSGB 1936 British National Grid, with
EPSG code 7405. An associated GeoPackage Easegill-Pippikin.gpkg (generated by
running Easegill-Pippikin.3d file through the QGIS3 .3d import filter)
is also provided for convenience.
