Select By Location Missing portions of lines

FlightDeck

Hey all,

I imported road centerlines from Open Street Maps and need to select the lines that that fall within a polygon. The issue I am seeing is that when I use "Within" it selects only the lines that fall completely within the polygon, thus missing a portion of other polylines that would also fall within. If I use the "Intersect" option it selects all of the polylines, but also includes the portion of the lines that fall outside of the polygon rather than terminating the selection at the polygon boundary. Is there something within the OSM Data that might cause this? Do I need to modify the data to allow the partial selection of a polyline?

The select by location tool will not split the lines for you, so if a line crosses out of the polygon with intersect, the entire line would be selected.  If you are only after the part that is completely within, you will need to split the lines at the polygon boundaries first, or, if you have advanced license, you could use the Intersect GP Tool.
