    What have you tried, what happened when you did, and what do you want should happen? Could you elaborate on your question to include all relevant info? – Martin Apr 4 '14 at 14:48
  • we considered Xpos and Ypos as Latitude and Longtitude and tried plotting in map. For an e.g. Lat Lon 34 degrees (1.0926) minutes, 52 degrees (7.9615) minutes The above is plotting somewhere in Iran, expectation is all the above points should draw a polygon and plot in somewhere in India(Southern Region). – user65140 Apr 5 '14 at 9:37

    Can you add where on the Earth your data should be? – AndreJ Apr 5 '14 at 14:12
  • It should be ploted in India andhrapradesh – user28882 Apr 13 '14 at 5:50
  • Data is collected in Zone IIIA – user28882 Apr 20 '14 at 9:30

I think the data is rather in meters in a projected local CRS.

It might be necessary to add a high number constant to get the full coordinates needed for reprojection to WGS84.

For India, a set of local coordinate systems has been established, see https://deeppradhan.heliohost.org/gis/indian-grid

enter image description here

You have to know in which zone your data is collected.

It might as well be that a UTM coordinate system is used, with the first columns of both coordinates been stripped off.


EDIT

If you have no access to the full coordinates, sample lat/lon coordinates of some of your points grabbed from Google Satellite images or a handheld GPS unit might help also.

  • This may be a good answer, but, should you be providing it before the question is cleaned up? Just wondering... – Martin F Apr 20 '14 at 17:43
  • I wanted to push the question in a better direction than degree-minute-second-guessing. But it seems to be a bit difficult... – AndreJ Apr 20 '14 at 18:24
  • Great term: "degree-minute-second-guessing"! – Martin F Apr 20 '14 at 19:58
