Cave surveying is usually carried out with tape, compass and clinometer. This equipment is simple, portable and can be used in difficult situations that would prohibit the use of more accurate instruments e.g. theodolite and EDM based equipment. Sometimes cave surveyors make use of handheld laser distance measuring devices and targets for improved accuracy. Handheld GPS receivers are used to fix entrance locations so surface measurements are seldom taken.
The final output is a large scale plan and elevation showing symbols and notation for various types of formation, sediment, slopes, pitches, climbs, streamways etc. 3D cave-viewing software is available for enhanced visualisation. Measurements taken provide an essential record for future exploration and are of sufficient accuracy to predict connections with other caves and surface features.
We will be taking video, open shutter with bulbs, flash, slide and digital photography. The cave images we capture, will be enhanced by shots of the beautiful rural landscape, flora, fauna and people. These are essential for supporting publications, articles and seminars that follow up the trip and generate interest in the world of caving.
Many caves are known about and have been explored by the local population
for hundreds of years. It is sometimes surprising just how far locals
have ventured into cave systems with limited lighting, or have managed
to descend cliff-faced surface depressions. Despite this, it is still
possible to find untouched passages even in well trodden caves.
