CHAPTER 3 MAPPING THE COURSE The design of an archery course is a complex task requiring the consideration of many factors.The most important of these is safety.Particularly for courses restricted in terms of space,great care must be exercised to ensure that sufficient room exists for arrow flight around each target lane.Since most courses are in terrain which does not allow viewing from a single point,often with wandering trails, the ability to see the course layout at a glance is a valuable resource. Few people can visualize such a complex system in their mind,so being able to map the course with some degree of accuracy becomes necessary. COMPASS SURVEY Compass Survey. An archery course may be mapped with a compass using simple procedures.The care with which this Is done and the degree of accuracy used in taking measurements of direction and distance will determine the accuracy of the map. Rough compass bearings and paced distances will result in a coarse map sufficient for range briefings.Carefully plotted bearings and distances measured with a steel tape or rangefinder can produce an accurate map.This can help a designer by identifying possible safety problem areas. The Process. Any survey is based on the general principle that an unknown point can be identified by its distance and direction from a known point. Professional surveyors employ high-tech equipment and complex procedures to establish locations and areas to a high degree of accuracy.The requirements to map an archery course are less stringent. In general,to map a course we will conduct a simple survey of the course features(the trail,shooting stations,targets,etc.).A running sequence of distances and compass bearings between points on the course will give enough information to prepare a basic map. GETTING READY Equipment to Survey. The equipment you will need to conduct a compass survey Is very basic.You will need; • A compass,preferably one with the smallest bearing divisions you can find. If the bearing ring is marked every 10 degrees,you can estimate to the nearest two or five degrees for greater accuracy. • A means of measuring distance.You can pace the distances if you are consistent and know how many paces you take to 100 yards.A steel tape or a rangefinder would be better and more accurate. • Penal and paper. Equipment to Produce the Map. Once you have conducted the survey,you will need certain items for the actual production of the map.These are; • Graph paper, large sheets are better, I would recommend 1/4 inch squares. • A good protractor. A sharp pencil. THE SURVEY Starting Data. Before we begin,we should decide on certain methods for note-taking.This
