Find matching values and then paste a value

Hello

I have 2 seperate datasets. The first one contains X coordinate, Y coordinate and elevation. The second one has X coordinate, y coordinate and 0 if a glacier is not present, 1 when present. What I want to do is paste the colom with 0 and 1 together with the first dataset if the coordinates match.

So for example:

A  B  C   ;D  E  F
12 15 3156;18 12 0 
13 14 1354;12 15 1
18 25 1456;13 14 1
14 16 1462;14 15 0
18 12 3153;15 18 0

Coordinates match in the first, second and last row (first colom): 12 15, 13 14 and 18 12, so there a 0/1 should be copied and pasted behind it.

I don't know how this can be done?

Thanks in advance!
