the contour interval is the difference in elevation between contour lines that are next to each other
Contour interval
The definition of a contour interval is the difference in elevation between two consecutive lines.
latitude and longitude
Contour lines were first used in the Schiehallion Experiment. This was an experiment designed to find the mass of a mountain, and by calculation, the mass of the Earth!!Contour lines were invented by Charles Hutton, in 1774, as a method of determining (in that case) the volume of the mountain.They are now commonly shown on topographic maps as a method of indicating the shape of the land and the depths of lakes and the sea. The intervals vary according to the need of the map, but common 1:50 000 maps have then indicated every 20 m, with the 100m lines shown slightly bolder.
