Converting from UTM 37N WGS84 to ADINDAN ?

Hi All,

I would need to convert some well locations from reference datum WGS84 to ADINDAN using the Arctool box.

I have three options given:

Adindan_To_WGS_1984_1

Adindan_To_WGS_1984_4

Adindan_To_WGS_1984_7

I understand from precedent discussion that for wells located in Lac Tana Ethiopie area I should be using the option Adindan_To_WGS_1984_4.

However when I apply this method it doesnot result well as my points initially in WGS84 remain inchanged.

Would you know whether I should first edit the method of transformation and what should be changed ?

Where to find the correct parameters (see attachements for the actual I have) to edit and update Adindan_To_WGS_1984_4 ?

Thank you for guiding me on this.

Best regards,

Loïc, France.

They are probably changed, you just don't see it.

Open a brand new ArcMap session, add your Adindan based output. Add the original. When the warning comes up about different datums, just click Ok, ie ignore it.

You should have 2 sets of points, displaced by approx. 280m.
