<div id="ygrps-yiv-246471820">The contour interval varies because the maps on Topo! are actual high <br/>
resolution scans of the paper topo maps.  In most locations the <br/>
contour interval is 10 feet.  However, mountainous frequently use a <br/>
20 foot contour interval.  Some topographically challenged areas <br/>
(like Florida) sometimes use a 5 foot contour interval.<br/>
