What is the pole?
The Range field, which can also be called lining pole, is painted with alternating stripes of different colors in consistent widths used often to measure space. This tool can be common for inspectors where stripe colors are usually red, white or red and yellow. Colors are selected on the basis of their visibility. One end of the pole will usually have either a pointed tip or a shoe to help stand on the edge. Poles of longer range can be equipped with a tripod or stand. Surveyor then observes the pole through the reconnaissance tool. The most common reasons why the range is used is to calculate unknown angles, heights and distances by means of other equipment. Surveyor notes that the point in the distance falls among the permanently spaced stripes at the pole and by entering this information and the known distance to the pole to the formula can calculate unknown measurements.
Some modern poles of the range can be equipped with hardware of global positioning (GPS). In this case the pole actsAs an antenna for a GPS unit, with a receiver at the top. These poles of GPS antennas allow more accuracy in the survey. Some versions of the modern poles of the series are also telescopic.
The pole range can be made of wood, metal, glass fibers or any composite, but the solid material that can withstand bending is ideal. However, non -conductive security materials may be preferred in some applications. Strong materials that can be easily produced as tubes are suitable for telescopic poles. Although the pole itself is made of another material, the common choice for a pointed tip is metal, because it can be easier to stick to the ground and is unlikely to wear other materials.
regular range Poles are normally 8 feet (approximately 2.4 meters) long and 0.5 to 1 inches (about 1.25 to 2.5 cm) in diameter. Foldable poles of the range differ in length, but may extend around 20 secondsTop (approximately 6 meters), while the longest poles designed for use with GPS units. Increased length allows antenna poles to expand the GPS unit from potential obstacles such as trees. Common width for stripes is 1 foot (about 30.5 cm).
