Many people have expressed interest in information on the
location of Debian developers.
We therefore decided to add, as part of the developer database
a field where developers can specify their world coordinates.
The map below was generated from an anonymized
list of developer coordinates
using the program
If you are a developer and would like to add your coordinates
to your database entry, log in to the
Debian Developers' Database
and modify your entry. If you don't know the coordinates of your
hometown, You should be able to find it from one of the following
The format for coordinates is one of the following:
- Decimal Degrees
- The format is +-DDD.DDDDDDDDDDDDDDD. This is the
format programs like xearth use and the format that
many positioning web sites use. However typically
the precision is limited to 4 or 5 decimals.
- Degrees Minutes (DGM)
- The format is +-DDDMM.MMMMMMMMMMMMM. It is not an
arithmetic type, but a packed representation of two
separate units, degrees and minutes. This output is
common from some types of hand held GPS units and
from NMEA format GPS messages.
- Degrees Minutes Seconds (DGMS)
- The format is +-DDDMMSS.SSSSSSSSSSS. Like DGM, it
is not an arithmetic type but a packed representation
of three separate units: degrees, minutes and
seconds. This output is typically derived from web
sites that give 3 values for each position. For
instance 34:50:12.24523 North might be the position
given, in DGMS it would be +0345012.24523.
For Latitude + is North, for Longitude + is East. It is
important to specify enough leading zeros to dis-ambiguate
the format that is being used if your position is less
than 2 degrees from a zero point.
