A compass traverse may be used to map a small area accurately or to conduct an open-ended traverse. A traverse is often used in mapping for resource inventories. A compass traverse is time-consuming, so it is a method used for making scale maps of relatively small areas.
It is a relatively simple step-by-step process to measure bearings and distances on the ground and then draw them to scale. This process therefore offers a hands-on way to clearly see and work with the basic elements of scale maps - the relationship between scale, distance and direction

Yes, he invented the Parabolic compass (a mathematical compass)!
The term "compass direction" means a direction shown by a magnetic compass, one whose needle will be drawn to a north-south alignment. When at a location and facing a certain direction, the "compass direction" is the one at the top (front) of the moving compass rose. If a location is in that direction, it is the indicated compass direction from the current point.On a map, the direction from one point to another is indicated by the up-down and left-right line between the points, and the compass directions are indicated by a compass rose on the map.

prismatic surveying and surveying compass.
The prismatic compass is a type of compass use for survering a land.

The disadvantages of using a compass for surveying is that readings are often inaccurate (accuracy dependent on size and graduations of compass, it is easily disturbed by effects of local magnetic attraction
A surveyor's compass, or a circumferentor is a device used in surveying to measure horizontal angles. It is used by directing the line of sight.
To conduct compass surveying, stand at a known point and sight the compass toward the new point whose direction you want to measure. Record the bearing shown on the compass. Repeat this process at multiple known points to triangulate the position of the new point. Calculate the coordinates of the new point based on the triangulated bearings and distances.
The local attraction are the error affecting device available at near by the compass while doing surveying. the local attraction is the effect of the magnetic materials on the compass and gets the incorrect bearing.
Drawing accurate circles and part circles in surveying, mathematics and geometry in schools and at work where planning is involved.

advantage it helps u know the direction of your measurement in relation to magnetic bearing disadvantage it is affected by the weather
The first proportional compasses were invented in the mid sixteenth century. Galileo invented a geometric and military compass in Padua in 1597. With his compass it was possible to make all sorts of arithmetical and geometrical calculations, from calculating interest to square and cube roots to drawing polygons and surveying.
