All the larger caves in north Wales have been surveyed. The most up-to-date versions have been carried out by North Wales Caving Club and should be available on request. These include..........

Basic cave
surveying (up to BRCA grade 3) is surprisingly easy and, to get started, all it requires is
an accurate (to within one degree or better) compass such as a Suunto, a measuring tape, notebook and pencil. A simple
clinometer is required when producing sections. Computers now take the hard
work out of plotting surveys and give a professional look to even the most
basic of surveys. Software such as Microsoft Publisher (used on this
website for several plans such as Afon Meirchion Cave) makes the end
result look professional and is easy to use, but there are many
others, although most are more difficult to get to grips with.
Other computer programmes produce digital
3D cave surveys. These do require the raw data to be input, which of
course, means that surveying still has to be done, but the finished
survey can usually be viewed from any angle or as a 'fly-by' movie.
For beginners, find a nearby cave perhaps one or two hundred metres long to practice on. There are many cave survey programmes available on-line, but p opular ones include.....

Paperless Cave Surveying
The most recent advance in cave surveying is of course, digital. A popular method uses one digital device to take measurements, and another that draws the survey. The two devices talk to each other via Bluetooth.

Laser Surveying
This is possibly the most detailed and visually pleasing representations of undergound environments.
