Description: <DIV STYLE="text-align:Left;"><P><SPAN>Represents geographic extent of all route patterns. Coincident with HERE basemap.</SPAN></P><P><SPAN>Fields Footprint_FT and Footprint_MI represent length of each route network calculated by buffering the geographic extent of the route.</SPAN></P><P><SPAN>Note, this is a different methodology than the length in Route_Length. Route_Length is based on a single-line representation of the HERE network where split roadways are represented (so does not refelect the actual roads traversed in such cases) and should be used for length-based analytical calculations.</SPAN></P></DIV>
