Trapezoidal Split Features and Advantages and Disadvantages

1. Features: trapezoidal divisions use the latitude and longitude lines as the benchmark, dividing the map into trapezoidal shaped panels, each with a clear geographic scope, suitable for topographic maps of various countries and small-scale maps, and able to cover a large range of geographic areas.

2. Disadvantages: the outline of the trapezoidal division of the map has no clear geographic coordinates, the entire mapping area can only be projected once, which will lead to a certain degree of deformation, with the rise in latitude, the same latitude and longitude difference limited by the map area is constantly shrinking, is not conducive to the effective use of paper and printing press layout.
