Hi

I'm fairly new to eCognition but wondering if you can help.

I'm classifying a Sentinel 2 image and trying to add a rule of 'distance to class', assuming that it would measure the nearest point of an object to the border of a class. In this case I was trying to classify 'shoreline' by being no more than 2 pixels from a classification 'water'. However the distances don't make sense unless it's measuring to a class centroid or something. Objects that share a border with water are shown as a distance over 80m or 8 pixels but further objects are sometimes less.

There are no layers with different projections in the project.

Can anyone help me?

Thanks, Steve
