Hello,

I'm experiencing some issues with the geoshape fields in my Survey123.

I'm using these field in a related table (repeat) to measure different areas.

When using this basemap (which is in New Zealand Transverse Mercator 2000 (2193) ) the area size (measurement) is not correct. However, when using ESRIs Imagery instead, the measurement seems to be correct.

The spatial reference of the survey is 4326.

Is there any workaround available?

Cheers,
Marco

Hi @MarcoPoetsch  The Survey123 app only supports WGS 1984 Web Mercator (Auxiliary Sphere) .
