Tapes are essential in surveying for accurate, durable, and short-distance measurements. Made from lightweight, nylon-coated steel, they offer flexibility and strength for rugged outdoor use. The nylon coating protects against rust and wear, extending the tape's life. Standard lengths, around 30 meters, are marked in meters and millimeters for precision.
Surveyors select tapes based on site conditions and accuracy needs. Lightweight, nylon-coated tapes are commonly used for ease of handling and durability. For high-precision measurements, heavier steel tapes, coiled into loops or on reels, are preferred for their stability in critical measurements where slight errors could impact data accuracy. Fiberglass tapes, made from glass fibers coated in polyvinyl chloride, provide a durable alternative. Though slightly less precise, they resist temperature changes and stretching, making them ideal for varied climates.
Range poles help surveyors align and mark points, keeping measurements straight over large areas. Taping pins mark tape ends with visible colors like red and white and may have cloth strips for better visibility. Hand levels keep tapes horizontal on uneven terrain, while spring balances add consistent tension to reduce sagging. Clamping handles hold tapes securely without damage, which is especially useful for partial lengths. Together, these tools ensure reliable, accurate distance measurement in surveying.
