Describe the elements of map projection.

1. Reduced earth : The model of the earth is represented by the help of a reduced scale on a flat sheet of paper. On this model the network of graticule can be transferred.

2. Parallels of Latitude : These are the circles round the globe parallel to the equator and maintaining uniform distance from the poles. They are demarcated as 0° to 90° North and South.

3. Meridians of Longitude : Longitudes are also the elements of map projection. These are drawn north to south direction from one pole to the other and two opposite meridians make a complete circle i.e. circumference of the globe.

4. Global Property : These are :

(i) distance between any given points of a region;

(ii) shape of the region;

(iii) size or area of the region in accuracy;

(iv) direction of any one point of the region bearing to another point.
