Geomorphology map measuring and reading scale and in-situ map scale combination

Abstract

The invention provides a geomorphology map measuring and reading scale and in-situ map scale combination which is composed of a map measuring scale and an in-situ map scale. The geomorphology map measuring scale is manufactured on round transparent organic glass being 22 centimeters in diameter and 0.35 centimeter in thickness, and the main scale body of the in-situ map scale is manufactured on rectangular transparent organic glass being 28 centimeters in length, 10 centimeters in width, and 0.8 centimeter in thickness. The map measuring scale integrates the functions of a coordinate azimuth angle scale, a magnetic azimuth angle scale, a circumferential angle scale, a slope scale, a tic-tac-toe grid coordinate scale, a calibration coordinate parallel line auxiliary scale, a 1:25000 or 1:50000 or 1:100000 precise coordinate measuring scale, a nylon line scale and the like, so that requirements for measuring and reading various kinds of data on a map and quickly calibrating coordinate north can be met through one tool. The in-situ map scale integrates the functions of a compass scale for calibrating the magnetic north on a map, a parallel line scale, a direction line calibrating rod of a ground object target, a centimeter scale and the like, and therefore the requirements for quickly and accurately mapping a target direction line through the map and the like are met.

Description

technical field [0001] The invention relates to a measuring ruler on a topographical map and a measuring ruler on the spot, which are two multifunctional tools for reading on a map and using a map on the spot in topography, especially when using a map in the field. The applied map reading and on-site map tools are characterized by multiple functions, fast speed, and high accuracy. You can use a map reading ruler to quickly read the coordinate azimuth, magnetic azimuth, and circumference angle on the map. , slope angle, grid coordinates, precise coordinates, etc.; a local ruler can be used to quickly calibrate the magnetic north direction of the map, quickly and accurately aim at the obvious objects on the spot on the map, and quickly draw direction lines, etc. . The reading ruler on the map and the on-site map ruler are simple and practical, and they are the best combined tools for completing various operations on the map.
