toolbar brings up popup menu with:
- UTM/Lat long (below)
- Specialized options. There is a bug
which affects most of these, which will present an error message. You
can click through with no ill effects. If the presence of the bug
offends you, just don't use it. It offends me as well, but I have been
unable to track it down, and life is just too short to obsess over
everything. The alternative at this point is to just remove the
options, but I think having the capability, even with the slightly annoying
bug, is the better option.
- Lat/long from PLSS
If you want to do batch coordinate transformations from Lat/long in WGS84,
you can create a database and use the options on the Edit
menu of the database
table form to convert to UTM, MGRS, or Mercator x/y.
This window allows coordinate conversion. It will convert between
any two datum in the list in DMA TR 8350.2.
Input data goes on the left side of the window, and the
converted data on the right. The memo box at the bottom of the
window contains the results of your conversions, which you can
save to a file or print.
Enter coordinates in three ways by clicking on the small
globe. The coordinates will
be converted for the local datum in the input box.
- Lat/long . Enter
degrees, degrees and minutes, or degrees, minutes, and
- UTM by entering the x (northing), y (false easting),
hemisphere, and UTM zone.
The output to the right will display in all three formats.
The display in the box at the bottom will put the input
coordinates in the same format you entered them. You can select
one or more output methods (lat/long, UTM, or MGRS). The buttons
above this box control the display:
- Convert performs the current conversion and prints
the results to the display box.
- Overlap computes the coordinates in the adjacent 6
degree UTM zone, provided that the location is within 40 km
of the zone boundary.
- Clear zeros the display box.
- Save lets you save the conversions to a text file.
- Print sends the conversions to the printer.
The check boxes on the right control how the output will be
displayed in the display box at the bottom. You can select as
many as you want of the output methods, including Lat/Long, UTM,
or MGRS. You can also automatically display overlapping
coordinates if the selected location is within 40 km of a 6
degree zone boundary, and have the lat/long in all three formats..
The buttons on the bottom of the form :
- allow you to exit the window (OK or Cancel),
- display the help
You can set the input and output datums as identical if you
only want to display equivalent MGRS, UTM, or lat/long
- Will not convert with the UPS grid in the polar regions.
- Will not handle the special cases of the UTM/MGRS grid in
Norway and Svalbard.
- If converting between WGS84, and NAD27 or any of the
datums that use the Bessel ellipsoid in Europe, you must
be aware that the 100,000 m grid square designators
change by 10 characters in the y direction (e.g. WA
becomes WL in the West Point vicinity). As with all MGRS
coordinates, the letters I and O are not used to avoid
confusion with the numbers 0 and 1, and X ,Y, and Z are
