The grid contains the outlines of photogrammetric image sections at the national level.
The grid was created by drawing kilometric grid lines that divide the national territory into square sections measuring 10 x 10 km. This division starts from coordinate 130000, increasing eastward, and coordinate 760000, decreasing southward.
The name of each section is determined by the first two digits of the stereographic projection coordinates of the top-left corner of the section.
