What is a cross-section view in geology?
What is a cross-section view in geology?
A geologic cross-section shows geologic features from the side view. They are similar to the topographic profiles that you have already created, but include additional information about the rocks present.
What are the 4 things that would be included in a geological cross-section map?
There are four things to include on every geological cross-section: a legend, the orientation of the line the cross-section represents on the map, a title, and a scale (e.g., Figure 8.11C).
How do you make a geological cross-section in ArcGIS?
Section 1. Getting started
- 1.1 Loading base maps into ArcGIS. Open ArcMap and create a new “mxd” file.
- 1.2 Downloading the ESRI Geologic Mapping Template.
- 1.3 Projecting the Geologic Mapping database.
- 1.4 Managing feature classes and topology in ArcCatalog.
- 1.5 Adding the Geologic Mapping database to ArcMap.
What scale is used on a cross-section?
It is typical to increase the vertical scale ratio by an order of magnitude compared to that of the horizontal scale. So if the horizontal scale is 1 inch equals 100 feet, a typical vertical scale for the geologic cross section would be 1 inch equals 10 feet.

How is geological mapping done?
Basic steps of geological mapping consist of observation and measurement in the field, taking samples, and analyzing samples in a laboratory. Geological mapping is a multidisciplinary method that combines petrology, structural geology, geomorphology, paleontology, stratigraphy, sedimentology, etc.
How do I create a transect in ArcMap?
In the Geoprocessing pane, search and open the Generate Transects Along Lines tool. Configure and run the Generate Transects Along Lines tool. In Input Features, specify the line feature as River_velocity. In Distance Between Transects, specify the distance between two transect lines as 200 Meters.
