Interactive
statewide topographic map
The Department of Water Rights created a statewide interactive
topographic map index by "stitching together" 1:24,000-,
1:100,000-, and 1:250,000-scale digital topographic maps of
the entire state. This allows users to view all or parts of
many topographic maps at once. 1:24000-scale digital orthophotos
quadrangles are similarly stitched together, and can be merged
with the 1:24,000-scale topographic maps.
About Topographic Maps
A topographic map shows the 3-dimensional surface of the
earth on 2-dimensional paper using elevation-contour lines.
Contour lines join points of equal elevation above a specified
reference, such as sea level. Think of a contour line as an
imaginary line on the ground that takes any path necessary
to maintain constant elevation.
A topographic map gives direction, location coordinates,
scale, and description of features, such as roads, trails,
rails, canals, streams, towns, political and geographic boundaries.
Symbols on the map represent buildings, water tanks, mines,
picnic sites, and other small features not to scale.
People frequently use topographic maps when hiking. Builders
use topographic maps to figure out where to put buildings
and roads. There's a topographic map like this for every part
of the United States.
There are 3 basic map series designated by relative scale
and degrees or minutes of longitude/latitude:
