-Load global mapper project, drag a box around bottom left user created feature grid vertice.
+**2021-10-05 Global mapper Latitude/Longitude config tutorial for ArmA 3 real world data terrains.**
-RMB -> vertex editing -> set position of selected vertices.
+Load global mapper project, select user created feature grid.
+RMB -> crop combine/split/split functions -> subdivide quadliteral area. Use grid number of rows and columns: 2, click OK. On modify feature info dialog click OK.
+Drag a box around the new vertice in center of your user created feature grid, then RMB -> vertex editing -> set position of selected vertices.
 Tick geographic coordinates (latitude/longitude).
-Copy paste latitude and goto [[http://www.latlong.net/degrees-minutes-seconds-to-decimal-degrees|latlong.net]] website, paste values to latitude box. Repeat this for longitude.
+Copy latitude to clipboard and go to [[https://latlongdata.com/lat-long-converter/|Lat Long Data]] website, paste values to "DMS (Degrees, Minutes, Seconds)" latitude box. Repeat this for longitude.
-Note that this websites longitude seconds input box only accepts integers (full numbers, no XX.XXXXX).
+Click green convert button and now you have two values, "DD (Decimal Degrees)" latitude and longitude.
 For some reason arma3 **latitude is with NEGATIVE number if its north of equator**.
-Click convert to decimal degrees button and now you have two values. Copy paste lat to mapArea[] first line, shown below
+Now just copy-paste the calculated values to your config and don't forget the north of equator negative value.
-<code cpp>
-mapArea[] =
-{
-	-14.60974078, 42.84222222, // latitude here
-	,  // longitude here
-};
-</code>
-Back in global mapper drag a box around top right user created feature grid vertice, get the coordinates same as latitude.
+config.cpp
-Paste them to mapArea[] second line, shown below
-<code cpp>
-mapArea[] =
-{
-	-14.60974078, 42.84222222, // latitude here
-	-15.35597344, 43.59888889 // longitude here
-};
-</code>
-Next we get the center latitude longitude coordinate for the terrain, go back to global mapper, select the whole user created feature grid, RMB -> crop combine/split/split functions -> subdivide quadliteral area. Use grid number of rows and columns: 2, click OK. On modify feature info dialog click OK.
-Drag a box around the vertice in center of your user created feature grid, get its coordinates same way we did above.
-Paste values
 <code cpp>
 latitude = -14.98310431;

-Finally grab the mapZone value from global mapper status bar (bottom) where it says like UTM 38N.
-<code cpp>
-mapZone = 38;
