CRYSTAL WIND SOFTWARE
ORANGE - CONVERT LATITUDE/LONGITUDE TO NORTH/EAST
------------------------------------------------------------------
ORANGE contains the following files:
ORANGE.DOC - The file you are currently reading.
ORANGE.EXE - Coordinate Conversion Program
------------------------------------------------------------------
Crystal Wind recently released a series of files (NAVAID, NAVAIR, NAVILS)
to the FSFORUM; Lib 6, which contained numerous locations around the U.S.
and Canada. The north/east coordinates for these locations were developed
using the "Orange" formula to convert from latitude/longitude.
This program is a quick and dirty translator using the Orange formulation.
It asks for the latitude/longitude coordinates and responds with the FS4
north/east equivalants. This program is not a replacement for the PathStar
calculator as described in NAVILS. It is strictly a stop gap until we can
get PathStar ready.
The latitude/longitude numbers can be entered as either HH:MM.mm or
HH:MM:SS.ss. The only thing that you have to watch for is that each part
of the entry (HH, MM, SS) MUST be two characters in length with the
exception of longitude hours which must be three characters. For example,
longitude 88:1:22 must be entered as 088:01:22. The following is from a
screen dump while processing:
ENTER LATITUDE
29:39.53
ENTER LONGITUDE
098:25.87
CONVERTED NORTH = 12081.8520
CONVERTED EAST = 12603.4091
CONVERTED CANT = 05.99-
ENTER LATITUDE
29:39:31.8
ENTER LONGITUDE
98:25:52.2
CONVERTED NORTH = 12081.8520
CONVERTED EAST = 12603.4091
CONVERTED CANT = 05.99-
ENTER LATITUDE
QUIT
C:\FS4\SEE>
Note that the first longitude was preceded by a zero while the second was
preceded by a space. Either way works fine. Also note that the first
example was made in fractional minutes while the second was fractional
seconds. As both sets of latitude/longitude are equivalent, the resulting
north/east coordinates were identical. The cant information is correct
outside of FS4's "populated areas".
If you feel that any of these offerings are worth while, leave us a note
at 70334,740. We are trying to gauge interest in this stuff and future
development will probably be in direct proportion to the interest shown.
