Answer» Sketch, blueprint and map are sequential forms of development and use of maps. Following is their description – Sketch – Sketches are made to depict various special places. They are not drawn on a scale and they do not convey the correct proportion among different pictures, directions and distances. They are used to depict some place in the form of a raw sketch. Blueprint – Blueprint is used to depict a small region. So, a sketch of a small region drawn with a large scale is known as blueprint. It has limited utility. For example – a blueprint of a school building which shows all the classrooms along with their length and breadth. Map – It is used to represent larger regions. Maps have a fixed scale. It is used to depict the distance, location, direction and distribution of a particular place in correct way. |
