उत्तर

Marginal Information: It includes the topographical sheet number, its location, grid references, its extent in degrees and minutes, scale, the districts covered, etc. In other words, it provides information related to what exactly a topographical sheet is showing. Without this marginal information, it is not possible to derive any meaning from a topographical sheet.
