and UTM Format,

-This package contains:

UTM_UTIL - This simple program will ask you the UTM Easting and Northing, (You will have to type them) and it will show on the screen the converted WGS84 Coordinates.
konv_vec_utm2gpsu - This will convert DXF files to GPS utiliy, see the next section for details
konv_vec_utm2gtm - It's the same as the above but the target format is GPS Track Maker Text File, see the next section for details

Both GPSU and GTM Files are openable by DG-Terrain Viewer, see http://www.geocities.com/drgportugal/dgtv

/***********************************************************
	CONVERTING DXF FILES TO GPS
***********************************************************

Both the konv_vec_utm programs where specialy made to be used with the Portuguese Vectorial Map on AutoCad format (DWG) available at download section the Portuguese Army Institute of Geography website (www.igeoe.com)
It is not granted with any other file.

Here is how to use it:
1st - Go to the IGEOE website and download the "500mdwg.dwg" file from the download section
2nd - Open it with Autocad
3rd - Select all the lines you want to convert.
4th - Go to the File Menu and click Export
5th - Select the DXF R12 format
6th - Click on the OPTIONS button and turn on the "Select Objects" CheckBox
7th - Back to the export dialog type the name of the file and complete the export.
8th - Close Autocad

9th - If you want to convert the information to GPS Utility Format, run konv_vec_utm2gpsu.exe, or if you want to convert the information to GPS Track Maker Text File run run konv_vec_utm2gpsu.exe
10th - It will open a mini-explorer dialog to select the input file, choose the file you created on the 7th step.
11th - Type the name of the target file, them you'll see lots of coordinates passing by and then It's done!

If you use DG Terrain Viewer click on the DRC Button to load the terrain Mesh (most likely to be PORTUGAL.DRC) then Click the GPSu or the GTM Text Button to open the file you created on step 11th.
If you use GPS Utility, Open the file as you usually do
If you use GPS TrackMaker Open the file, but don't forget to choose GTM Text File on the mini-browser dialog.

ATTENTION: This program comes with no guarantee of precision, use it on your own risk, althought it was intensively tested the author will not be responsable for any trouble that this program can cause directly or indirectly.
- anyway, the few tests made revealled that the precision of the conversions where almost the time less then 10 meters.
