A topographic map, or toposheet, depicts a three-dimensional terrain area in two dimensions. Since topographic maps display the landscape's horizontal and vertical location, they set themselves apart from other types of maps. It uses a combination of colour, symbols, labels, contour lines, and other graphical elements for visual representation. Topographic maps show the shapes, locations, and various anthropogenic and natural elements. Survey of India has devised a map numbering system to make it easier to identify a specific area map.
Scale-based classification of toposheets:
Large-scale Map: With a scale of 1 in 1000 or less
Medium-scale Map: These maps have a scale from 1 in 1000 to 1 in 10,000
Small-scale Map: Maps with a size of 1 in 10,000 or more.
Here’s a step-wise instructional guide on downloading toposheets from the Survey of India website.

Ellipse is a fundamental component of a conic section and shares many characteristics with a circle. An ellipse is oval in shape as opposed to a circle. An ellipse is a shape with an eccentricity less than one that symbolises a group of points whose distances from its two foci are added up to a fixed value. Everyday examples of the ellipse include the shape of an egg as well as the race track in a sports field.
