Hello there,

is it possible to transform coordinates from Gau??-Krueger-4 in WGS1984 with the iOS SDK?
I am looking for something like this: How to create a predefined geotransformation
but for iOS.

Greetings
Philipp

Yes, it is possible to transform coordinates from Gauss-Kruger zone 4 (EPSG:3334) to WGS1984 (EPSG:4326). You should use projectGeometry method of AGSGeometryEngine to do so.

However, you cannot create your own geotransformation.

Hi Nimesh,

I am in Canada. We want to convert coordinates from NAD27 to/from NAD83 system. To do so, we need NTV2 file. I am wondering how we can apply this file in iOS world?

Thanks,

Zhiling
