Simplify the reading of “flat” contour maps and understand the relation of contour lines to relief with this useful, introductory book. The book features 10 typical landforms-hills and valleys, glaciation, canyons, volcanoes and lava flow, anticlines and synclines, and even Moon craters. First study the two-dimensional contour topographical maps, where surface features are identified with letters. Then locate the same landforms on the adjacent stereo contour maps for comparison and view the elevations in 3-D. Stereoscope glasses (listed separately as AP5264) are needed to view the images in three dimensions. Glossary; 1995, 32 pages, 8 1/2" x 11", spiral-bound.
