• added Project button:

• G (Load MapSource® Data): When pressed, the user may choose one or more Garmin® MapSource® data export files (*.txt) to load into a new Table of point data (*.dbf; defaults to same name and location) in the Project, for use as an Event Theme in ArcView.  All saved data attributes are loaded into appropriate fields, and coordinate fields are further converted to ArcView-readable format.  Attributes allow selection of point sets associated with particular tracks or other GPS features gathered.  Functions available in the separate NVTools extension facilitate conversion of such point sets to lines or polygons.  Tested with Garmin® MapSource® versions 4.09 - 6.8.0 and eTrex® Legend v.3.50, and designed to detect and load previously undocumented data fields, so should work with most similar combinations.
