![]() These tapes are ideal for taking offsets but they don’t always provide precise measurements. Metric woven metallic tapes are more durable than cloth or linen measuring tapes. The tape can then be rolled up using a hand crank that is fitted on the outside of the circular storage case of the measuring tape.Ĭloth tapes are light, portable, and flexible but they are not too durable since moisture can make the cloth strip shrink. The normal linen tape usually has a metal ring at the end that can be hooked around a spike so you can pull the tape out to measure a distance. ![]() Shorter tapes can be pocket-sized but longer ones tend to be much too big for your pocket. These tapes are usually sold in varying lengths of 10 to 150 meters that are coiled around a spindle in the center of the device. These long tape measurers are usually made with a strip of varnished linen that is about 12 to 16 millimeters wide. Here is a quick look at some of the most common measuring tape types that are useful to land surveyors. There are many different types of measuring tapes and devices available on the market and any surveyor will likely have quite a few different types and designs in their collection. Types of Measuring Tape Used for Surveying Synthetic tape measures are handy for surveying areas like railway lines or regions underneath electric fences where you can’t use a metal tape or where a laser measuring tape might not function properly. Invar tapes are often required for these types of measuring works. Trichometryh calculations can then be used to calculate the other two distances of the triangle. With this type of method, you only need to accurately measure out one distance and take the angle measurements at the corners. This type of surveying method involves measuring the angles formed when you are working with three control points. For these types of surfaces, it is best to use a steel rust-resistant tape that will offer accurate measurements without being affected by moisture. Take Measurements in Wet AreasĮlectronic or digital equipment can’t hold up when you take measurements of wet surfaces or in rainy weather. With offset measurements, you can locate an object that lies in the vicinity of the mainline. Take OffsetsĪn offset is a specific distance that is taken from either side of a chain line. A good old spring coil pocket measuring tape is ideal for making shorter measurements or for measuring construction accessories like poles. It isn’t very practical to set up our laser measuring device with its tripod and accessories if you are only measuring out short distances. ![]() ![]() Measuring wheels or a long measuring tape can be more helpful for these odd and textured surfaces. ![]() When you need to measure the distance of a contoured surface like a path over a sloppy hill, these tools usually fail since they only take the measurement in a straight line. Laser equipment is terrific for taking measurements of straight lines. In conditions where electronic devices like laser measuring tools won’t hold up, your standard rust-proof pocket tape measure or long tape measure will still hold firm. Modern tech equipment often fails you when you need to take accurate measurements in harsh climates, wet conditions, or mid-day. Take Accurate Measurements in Harsh Climates Here is a quick look at the times you will likely use this tool. Out of all these devices, the traditional measuring tape is likely one of the most frequently used items because it has so many uses. A land surveyor will likely have all sorts of measuring devices like rulers, chains, laser devices, and pocket tapes that can be used for taking large and small-scale measurements. There are quite a few different types of tools that can be used for measuring objects and distances. One of the most critical skills in surveying is the ability to take accurate measurements. ![]()
