As of this posting, 9 people have posted location tags, of which 6 are correct. Here are the 'rules' for how the tag must be expressed:
The first 3 digit group are the degrees. Valid values for this are -179 to 179. The second 2 digits are the minutes, and have valid values of 00 to 59. The third 2 digits are the seconds, and have valid values from 00 to 59. Do not use decimal expressed lat/longs! The parsing code checks for legal values, and will toss out any location tags that are invalid.
The format MUST be [sign]DDD.MM.SS, where DDD=degrees (000-179), MM=minutes (00-59, SS=seconds (00-59).
If you have used the decimal format, or have values that don't conform, please update your homenode. Use MapBlast
to find yourself. It will display the lat/long the map is centered on. Click the lat/long display in the upper right hand corner so it is displayed as Degrees/Minutes/Seconds (denoted by the first number having a degree symbol to the right of it). This is the number you want to use on your tag.
Remember that North values are positive, South values are negative for latitude, East values are positive, and West values are negative (everyone in the U.S.) for longitude.
