Special Topic on Contour Topographic Maps

A contour line is a closed curve connecting adjacent points with equal elevation on a map. Contour lines are divided into head curves, gauge curves, and intermediate curves. Contour lines measured and mapped based on basic contour distances starting from the elevation datum are also called basic contour lines. Starting from the elevation datum, every fourth first curve is a thickened contour line, also known as a thickened contour line. Contour lines measured and mapped according to one-half basic contour distance are also called half-distance contour lines. It does not need to be closed when expressed, but it should be expressed to the place where the basic contour intervals are small and the landform tilt is the same. Huajun Software Park provides you with contour topographic map topics for everyone to download. Different types and versions will definitely help everyone, so take a look.
