What is the latitudinal and longitudinal extension of a million sheet topographical map is?
Answers
Indian Topographic Maps
Topographic maps provides the graphical portrayal of objects present on the surface of the earth. These maps provide the preliminary information about a terrain and thus very useful for engineering works. For most part of India, topographic maps are available which are prepared by the Survey of India. To identify a map of a particular area, a map numbering system has been adopted by Survey of India. The system of identification is as follows:
An International Series (within 4° N to 40° N Latitude and 44° E to 124° E Longitude) at the scale of 1: 1,000,000 is being considered as base map. The base map is divided into sections of 4° latitude x 4° longitude and designated from 1 (at the extreme north-west) to 136, covering only land areas and leaving any 4° square if it falls completely in the sea (Figure 3.8).
Answer:
4° latitude and 4° longitude
Explanation:
Topographic maps gives the graphical depiction of items present on the outside of the earth.These maps give the primer data about a territory and in this way extremely valuable for designing works. For most piece of India, topographic maps are accessible which are set up by the Survey of India. To recognize a guide of a specific region, a guide numbering framework has been received by Survey of India. The arrangement of ID is as per the following: An International Series (inside 4° N to 40° N Latitude and 44° E to 124° E Longitude) at the size of 1: 1,000,000 is being considered as base guide. The base guide is isolated into segments of 4° scope x 4° longitude and assigned from 1 (at the extraordinary north-west) to 136, covering possibly land zones and leaving any 4° square on the off chance that it falls totally in the ocean.
