I live in Botswana. How can I convert the coordinates they gave me on a lease? I think it is very old system they use. Google Maps do not accept the coordinates. and ?earthplane? web age is only for USA.

On the lease is:

A=Y59665 X2493871
B=Y59460 X2493980
C=Y59701 X2494360
D=Y59819 X2494297

How do I convert the X & Y to degrees, minutes and seconds?

I have been searching in every Google site for a converter for these types of coordinates.

  • Sorry my caps lock was on from searching the X and Y coordinates... I am so confused by this things

    If you want someone to read your question (and answer it), then yes you should edit the question. If folks have a choice between reading an all-caps post and moving on to a new question, it's not going to be a close call.

    You have two different accounts, which makes it difficult to edit your own post. Please follow these instructions to correct this. The folks from whom you have leased are far more likely to be able to tell you the coordinate system they used than we are.

Correct CRS for these coordinates is EPSG:22287 (Cape / Lo27). Conversion from projected coordinates to EPSG:4326 (WGS 84) can be done at epsg.io: https://epsg.io/transform#s_srs=22287&t_srs=4326&x=58958.4440060&y=2491707.7922860

When converting, you have to swap X and Y. For example, for first coordinate A=Y59665 X2493871, when converting, it should be:

X = 59665
Y = 2493871

and converted coordinates are:

lon = 26°25'35.696" (26.4265822°)
lat = -22°31'28.591" (-22.5246087°)

How I found the correct CRS was by luck. Shortly ago I was helping somebody finding the right CRS in South Africa (Land Surveyor Coordinates). Since Botswana lies above SA and coordinates seemed similar, I searched at epsg.io first for Lo29, then Lo28 and finally Lo27, which was the right one. Pure (informed) quessing.

  • You are correct yes it is about 120km from Motshegaletau. I founded it online, the coordinates. I know that district uses -22° and just put that in front of the Y coordinates and the X they just left out the . after 24. The owners was given this lands and do not know where the land are. Some cannot read and write.

Botswana's grid coordinates is divided into bands of 2° and given as Lo21, Lo23 up to Lo27. Therefore to convert your coordinates the band that they belong to should be known.
