What is Prismatic Compass Survey?

This compass was invented in 1814; this compass consists of a small circular box of about 100m. This prismatic compass can either be used as a hand instrument or mounted on a tripod; and is very useful in a situation where rough surveys are needed, i.e., where the accuracy of the survey is not the main consideration but the speed.

What is Surveyor Compass?

Surveyor Compass is used for determining the horizontal direction of a line with reference to the direction of a magnetic needle, and it is considered as an accurate instrument for surveying.

History of Surveyor Compass?

A surveyor’s compass was originally a colonial instrument designed for use in places such as Ireland and America, where land was plentiful.rnThe first reference to an instrument of this sort appeared in William Folkingham, Art of Surveying (London, 1610).rnThe earliest extant example was made in Dublin in 1667 and is now in the Museum of the History of Science, Oxford.
