Answer 2

Answer:

Maps which represent a symbolic or conventional picture of the physical and cultural landscape of small area on very large scale are known as Topographical maps or topo sheets. The scale of the maps is large enough to show the physical and cultural features in detail.

Measuring topography can refer to mathematical assessments of elevation and streamflow, or it can mean defining various geologic and geographic variables to describe a region. Measure the heights and depths of the terrain. A topographic map's contour lines derive from regularly measured or extrapolated elevations.
