It was a very great deal of work gathering all this data and crunching it down into usable form. I hope you appreciate it. :-) The files are comma-delimited ASCII, in the following sequence:

1) Item Name
2) Item Type
3) USGS Chart Title
4) Item Altitude in Feet
5) Item County
6) Item State
7) Item Latitude
8) Item Longitude

Effort has been applied to provide Latitude and Longitude data to the fifth decimal place. South Latitude is negative, North Latitude is positive; West Longitude is negative, East Longitude is positive.

Note that before this data may be loaded into The NMEA Sage Waypoint Plotter ActiveX Control, the superfluious data must be removed.
