1. Map Tool: This geographic coordinate scale is designed for accurate distance measurement on 1:50,000 scale maps, with clear markings and beveled edges that make reading coordinates effortless. The latitude and length ruler provides precise measurements for navigation planning, topography analysis, and map distance calculations. Whether you're plotting coordinates for fieldwork, hiking routes, or educational purposes, this transparent measuring tool delivers consistent accuracy. 2. Professional Material: Made of clarity plastic, this topography measuring tool maintains exceptional transparency, allowing you to clearly see map details during readings. The geographic coordinate ruler features scales specially calibrated for 1:50,000 maps, with permanent markings that will not fade with regular use. The edges are carefully crafted to provide smooth, straight lines when drawing routes or measuring distances between points on your topographic maps. 3. TWO SIZE OPTIONS: Available in 14.5' and 18.5' lengths. This width and length ruler gives you flexibility based on your mapping needs. The longer option of 47 cm is for working with larger maps or measuring extended distances, while the 37 cm version offers greater portability for field use. Both sizes feature the same precise 1:50,000 scale markings. 4. MULTIPURPOSE FUNCTIONALITY: This topography ruler features numerous applications—from academic geography projects and land surveying to coordinate plotting and outdoor adventure planning. The width and length ruler helps translate map distances into real measurements, allowing hikers, sailors, and explorers to calculate precise travel routes and coordinates. The transparent design lets you see the underlying map features while plotting routes or measuring distances between points of interest.
