This is a blog that I created to illustrate maps that interest me. Through GIS-3015 I have learned many map types and those are illustrated in this blog.
http://asterweb.jpl.nasa.gov/gdem.aspA DEM Map refers to a Digital Elevation Map which is a map that uses remote sensing technology to depict the elevation of a certain geographic area. The DEM Map above was provided by NASA and shows the elevation of the entire globe. From this map you can tell that the blue areas are of low elevation such as Florida and green and yellow areas represent higher elevations.
