Introduction to Paperless Surveying (3 day course, split over 3 months)

March 24th - May 19th 2018

How Stean Gorge, Nidderdale

Cost: Free (£10 refundable deposit required)

Spaces: 10

This three day BCRA Cave Surveying Group course (spread across three months) will teach complete beginners about paperless surveying up to a standard where they can produce a straightforward paperless survey and be able to output a pdf map of a cave along with survex files and files to view using Google Earth.

After completing the full course, participants could expect to have enough knowledge and skills to be able to attend one of the more advanced courses planned by the Cave Surveying Group.

This course will involve training on using equipment underground in a nearby cave, but will be predominantly classroom based.
