Topographical Maps Section 2.4. Topographical Maps Topographic maps - show the surface features of an area - view the land from above (looking down) -

Topography is the shape of land and includes area’s elevation, relief, and landforms. Elevation is the height above sea level of a point on Earth’s.

Presentation transcript:

Structure Contour Maps Show contours connecting points of equal elevation on a geologic surface… Fault Contact Bed Etc. Show elevation of the top of some geologic feature.

Structure Contour Maps Drawn with a specific contour interval Trend of structure at any point is parallel to the contour at that point Strike is tangent to contour Dip is perpendicular to contour Rules of thumb for spacing of contours is same as for topography. Cross sections drawn using structure contours show shape and depth (elevation) of layer
