A number of the r.surf.* modules want the input data to be in raster form already, so we rasterize the contour lines, using the level column for the height values. Also some of the older r.surf.* modules only like to work on integers, so to preserve sub-meter fidelity we do a little trick where we multiply by a large number, do the process, then divide by that number again (to avoid terracing

Use the elevation marked on index lines to calculate the elevation of interval lines. For example, an index line marked "6500" means everything along that line is 6,500 feet above sea level. On a map with a 40-foot contour interval, the interval line to the inside of the index line …

The new shoreline of the island is a contour line because all of the points along this line have the same elevation, but the elevation of this contour line is 10 ft above the elevation of the original shoreline. We repeat this processes in the two diagrams below. By raising water levels to 20 ft and 30 ft above the original see level we can find the location of the 20ft and 30 ft contour lines

Contour interval: The change in elevation from one contour line to the next is always the same within the same map. Many maps have either a 40- or 80-foot contour interval: An 80-foot interval simply means that each contour line is 80 vertical feet away from the next closest line. You find the contour interval for your map in its legend.
