   where:

   LONGITUDE The real number describing the longitude encoded as a
             printable string. The precision is limited by 256 charcters
             within the range -90..90 degrees. Positive numbers
             indicate locations north of the equator.

   LATITUDE The real number describing the latitude encoded as a
            printable string. The precision is limited by 256 charcters
            within the range -180..180 degrees. Positive numbers
            indicate locations east of the prime meridian.

   ALTITUDE The real number describing the altitude (in meters) from
            mean sea-level encoded as a printable string. The precision
            is limited by 256 charcters. Positive numbers indicate
            locations above mean sea-level.

   Latitude/Longitude/Altitude values are encoded as strings as to avoid
   the precision limitations imposed by encoding as unsigned integers.
   Although this might not be considered optimal, it allows for a very
   high degree of precision with an acceptable average encoded record
   length.

I'm Alphons van der Heijden, living in Lelystad, Netherlands, Europa, Earth. And currently I'm retiring from hard working ( ;- ), owning my own company. Because I'm full of energy, and a little to young to relax ...., I don't sit down, but create and recreate software solutions, that I like. Reinventing the wheel is my second nature. My interest is in the area of Internet technologies, .NET etc. I was there in 1992 when Mosaic came out, and from that point, my life changed dramatically, and so did the world, in fact. (Y)
