Top 10 World Map ProjectionsMercator.
This projection was developed by Gerardus Mercator back in 1569 for navigational purposes.
This map is known as a ‘compromise’, it shows neither the shape or land mass of countries correct.
What is UTM zone of India?
For India, the UTM zones vary from 42 to 47 starting from the state of Gujarat on the extreme left to Arunachal Pradesh on the extreme right.
What are 4 types of map projections?
Types of Map ProjectionsGnomonic projection. The Gnomonic projection has its origin of light at the center of the globe. Less than half of the sphere can be projected onto a finite map. … Stereographic projection. The Stereographic projection has its origin of light on the globe surface opposite to the tangent point. … Orthographic projection.
What are the 3 main map projections?
Three of these common types of map projections are cylindrical, conic, and azimuthal.
Which projection is most widely used?
Cylindrical ProjectionCylindrical Projection – Mercator One of the most famous map projections is the Mercator, created by a Flemish cartographer and geographer, Geradus Mercator in 1569. It became the standard map projection for nautical purposes because of its ability to represent lines of constant true direction.
How do I choose a projection?
When you choose a projection, the first thing to consider is the purpose of your map. For general reference and atlas maps, you usually want to balance shape and area distortion. If your map has a specific purpose, you may need to preserve a certain spatial property—most commonly shape or area—to achieve that purpose.
Which of the following system is mostly used in India for projection?
polyconic projectionIn India, the polyconic projection is commonly used by Survey of India (SOI). All SOI toposheets are in the polyconic projection. Map Scale is the ratio of distances on map to distances to on the surface of the earth.
Where is 1st angle projection used?
First angle projection is widely used throughout all parts of Europe and often called European projection. Third angle is the system used in North America and alternatively described as American projection.
What is the 1st angle projection?
First-angle projection: In this type of projection, the object is imagined to be in the first quadrant. Because the observer normally looks from the right side of the quadrant to obtain the front view, the objects will come in between the observer and the plane of projection.
How many grid zones are in India?
5 regional gridsIndividual State grids were interconnected to form 5 regional grids covering mainland India. The grids were the Northern, Eastern, Western, North Eastern and Southern Grids. These regional links were established to enable transmission of surplus electricity between States in each region.
Which coordinate system is used in India?
General. The Indian Grid reference system is a system of geographic grid references different from the Geodetic Coordinate System (Longitude/Latitude). This system is used specifically by Survey of India Maps and consequently by a large number of Indian Government organisations.
Which projection is used in India?
angle projectionFirst angle projection is widely used in India and European countries. The object is placed between the observer and projection planes. The plane of projection is taken solid in 1st angle projection. 2.
