What reading level is A Little book On Map Projection book?
To quickly assess the difficulty of the text, read a short excerpt:
An elastic string when stretched tries to make itself as short as it can. We have seen that on a plane it will make a straight line. On a sphere it lies on a great circle. We therefore infer that — The great circle is the shortest line that can he drawn on the surface of a sphere hetween any two points.
This is why sailors like to sail on the great circle between two ocean ports. Generally the compass course has to be continually changed in order to keep on the great circle, but the saving of t...ime and, in the case of steamships, the saving of fuel compensates for the additional trouble.
With a little care great circles can be drawn with con- siderable accuracy by bending a card so as to touch the sphere all along one of its edges and moving the card so that the edge passes through the two points through which the great circle is to be drawn.
How TO Draw Meridians and Parallels on a Ball On the rim of the cup which fits the ball mark two points exactly opposite to one another. This is not so easy as it MERIDIANS AND PARALLELS 27 appears when there is nothing to mark the centre of the cup.
