Topographic Cross Section

Geologic cross sections are constructed on the basis of the geology mapped at the surface combined with an understanding of rocks in terms of physical behavior and three dimensional structures.
Topographic cross section. A cross sectional map shows the cross section from the side. It can also represent the extension of the materials of the structures that have been eroded above the topographic surface. Altitudes along this line are turned into a cross section.
Maps and cross sections are fruit of the interpretation of the arrangement of the rocks using diverse types of data normally incomplete and with different degrees of uncertainty. This lesson will demonstrate how to do this by looking at a map of armadillo ridge. Cross sections are constructed using the contour lines on a topographic map.
Earth scientists regularly use topographic bathymetric and geologic maps. There are some great online resources for obtaining topographic maps. In introductory geoscience courses a profile is appropriate when you are asked to construct a cross section or profile.
Topographic maps reveal the shape of a landscape. Topographic profiles are used to understand what a topographic map is telling you in a specific area or you can think about it like it is giving you a side view of the landscape along a specific line on the map. In other words if you could slice through a portion of the earth pull away one half and look at it from the side the surface would be a topographic profile.
A section line is a straight line drawn on a topographic map. A continuation of the topic of drawing a cross section from a topographic profile this time we look how to factor in different layers of rock if they are present on a map. Creating a topographic profile cross section.
Making a cross section from a topographic is not too difficult and can come in handy for hiking driving biking walking and yes running. A topographic map can be used to create a cross section along any line drawn on the map. A topographic profile is a cross sectional view along a line drawn through a portion of a topographic map.
