Label the “contour interval” you used at the bottom of the map.

Isochore maps measure the thickness from a point on the upper surface straight down to the corresponding point on the lower surface. These can be used if copying a surface analysis from a drawing to another.
The vertices of the triangles are spot elevations that may have been measured in the field by leveling, or in a photogrammetrist's workshop with a … An isopach map is a contour map showing the thickness of a given "stratigraphic unit." From this model it will create a 2-dimensional map with the selected layers. An isopach map is essentially a contour map of the specified strata values.
Surface Analysis - Copy Analysis to Another Surface This can be used if the surfaces are in the same drawing. An isopach map is a map that shows the thickness of something. In this tutorial, you will find guidelines on how to draw maps that look natural, vivid, and visually appealing. In this case, the contour interval is 10 feet. Both types of maps show the thickness between two mapped surfaces, but differ in how the thickness is measured. Draw its map expression (hint: the 500 m contour on the lower fault would be the 600 m structure contour on the upper fault). Isopach map is a map used to delineate the variations in thickness within a layer, tubular unit or stratum. An isopach map is a contour map showing the thickness of a given "stratigraphic unit."
The map will be displayed in a RockPlot2D tab in the Options window. In this case, it is the thickness of a limestone formation. Strata Isopach Maps. Finish the map by drawing the 10-foot, and zero contour lines. You can adjust any of the options along the left and click the Process button to regenerate the isopach model and the map.! How to Draw a Map. Isopach and isochore describe a map showing the thickness of a unit in the subsurface.
Isopachs are referred to as the contour lines with equal thickness over a particular area.
The result is a triangulated irregular network (TIN).A TIN is a vector representation of a continuous surface that consists entirely of triangular facets. Drawing maps of imaginary places is wonderfully fun; doing this can inspire your imagination and is also an unexplored form of art. Have a good weekend! For each strata in the drillholes, this routine can generate isopach maps, or isolines of the strata thickness, bottom elevation, and attributes such as moisture, sulfur, and BTU. ... How to Draw a Contour Map.
