location on the map new Report this article as Inappropriate to us !!!Login to Reply

Can anyone tell me how I can figure out where this country is located, if all I know is following information. I understand the country is located in UTM zone 36N, but where can I see the easting?

The Y origin -9998100 makes me think it's Antarctica.

Indeed, these coordinates are of the Antartic, but the zone 36N corresponds to the African countries of Sudan and Uganda.

I found also some additional data here:

Extent in the item's coordinate reference
Bounding rectangle
West longitude 222513.600000
East longitude 223413.600000
North latitude 1468525.800000
South latitude 1467925.800000

Am I right to think it is Egypt? 
When I take the East longitude from here, and it has to be located in UTM zone 36N..

If anyone could explain to me how to deteremine this location, I would be deeply grateful.

What software do you have? 


Quick and dirty approach:  Recall that the metric system was designed to be 10M meters from the North Pole to the Equator through Paris.  10M/90 degrees = 111111 m/deg. 


1468225 (middle of your box) / 111111 = 13.21 N.  This puts it in Sudan.


But UTM has some distortion. 


UTM equations for a spherical earth are fairly straightforward.  For an ellipsoid they're a little hairy.


Arc/Info gives 30.4453 E, 13.1967 N for a spherical earth; 30.4479 E, 13.2692 N for an ellipsoid.

Thank you very much for your answer!


I have ArcCatalog/ArcInfo as well. I have no idea though, where I can see that it gives 30.4453 E, 13.1967 N for a spherical earth and 30.4479 E, 13.2692 N for an ellipsoid.


I have never had anything to do with GIS before, so it is like a mystery to me..

If you have command line Arc/Info, use this projection file (call it file.pro):



  • INPUT

  • PROJECTION UTM

  • UNITS METERS

  • ZONE 36

  • SPHEROID SPHERE

  • PARAMETERS

  • OUTPUT

  • PROJECTION GEOGRAPHIC

  • UNITS DD

  • SPHEROID SPHERE

  • PARAMETERS

  • END


Then do:  PROJECT FILE pts.in pts.out file.pro or PROJECT COVER ptsin ptsout file.pro


If you have ArcMap, then use the "Project" tool (in "Data Management/Projections and Transformations/Feature") followed by the "AddXY coordinates" (in "Data Management/Features") tool.
