vertical (plane) views, terrain depiction elements

- contour lines = isohypses: imaginary lines connecting points of equal elevation, show geomorphological forms

- isobath = depth contours: show seafloor relief/ terrain as contour lines

- hachure: short lines of varying width drawn in direction of steepest gradient, steepness through darkness usually combined with lighting effect

- psysiographic: sketching landforms, plan/oblique view often combined with relief shading

- shaded relief: casting light across terrain produces lighted and shadowed parts, produces a plastic 3D effect, terrain better perceived
