Contour lines show the shape and spacing of the land, which lets you determine elevation, relief, and slope. Index contours are labeled contour lines that make elevations easier to read, and the contour interval tells you the elevation change between adjacent lines. “Topographic interval” and “index topography” are not standard map features for showing these details.
