[OSGeo Africa] Identify coordinate system

[Basson, FC]

Hi Zoltan

This page provides a nice list of possibilities: https://epsg.io/?q=Qatar%20kind%3APROJCRS
Click on the “Get position on a map” link for each projection to compare.
It seems like it must be EPSG 27039 or EPSG 32639.

Regards
FC Basson

Subject: [OSGeo Africa] Identify coordinate system

Hi Listers,
I've been asked o help a school-going daughter of a friend of mine in Doha (yes, this is "AfricaList" :-/  )
She has been given a shapefile without a projection file. The area is Al Wakrah, just South of Doha airport.

The numeric values of the geometry coords are around 560000, 2782000 - the second value looked like a distance from the Equator, so I tried UTM 39N
The scaling seems wrong, and it does not align with the coastline (QND95) shapefile I have.
(I also tried EPSG:27039)


As you can see, projection-sleuthing is not one of my strengths.
Can anyone point me in a direction to try and solve this?

Thanks in advance.

Kind regards,
Zoltan
