Topographic maps use contour lines to show the elevation of an area. These lines have rules: they cannot cross, and they form circles around hills or depressions. Explore topographic and geologic maps, and learn how to read their contour lines, geologic markings, and colors. ...

Is there any way to hatch only between two specific lines in a contour plot and not all of it? For example, a contour plot has a lines with values starting from 10 to 100 and I want to hatch between line 20 and 50. thanks.
isobars or lithic counts, and model the potential change between any two points. For example, the user has point data on a map representing the lithic (rock) material found at each survey point. Contour lines can be created by attributing each point to the lithic...
Knowing how to read a topographic map is the foundation of any backcountry adventure. Through the use of contour lines, topo maps bring a 3-dimensional element to a 2-dimensional paper map. Topo maps allow you to visualize the rise and fall of the land and “see” the depths of canyons...
Lidar (light detection and ranging) is an optical remote-sensing technique that uses laser light to sample the earth’s surface and produce highly accurate x,y,z measurements. Contour lines can be crea
Video: How to Read a Topo Map How Contour Lines Describe Terrain Simple trail maps are useful for trip planning but NOT for navigation in the field. Topographic maps go further, giving you the power to visualize three-dimensional terrain from a flat piece of paper. The feature that makes th...
I'm relatively new to Illustrator and I have a question regarding multiple contour lines for a path. I converted a text into a path and want to create multiple outlines You can see a quick sketch of my idea below. The space between the lines should be the same ...
If, for example, the general terrain is quite elevated, the map might run at 80- to even 100-foot (24- to 30-meter) intervals. This makes it easier to read the map — too many contour lines would be difficult to work with. Look in the margin of your map to find out its contour...
Today we’re going to discuss how to read terrain off of a map. Reading terrain is more about artistic visualization than it is science. There are three major factors that aid in the visualization of terrain from a 2d map: Contour Lines ...
