Hello Adriaan,

I believe you mean the extent of a frames from a time series data set … it should be the same as for a map and you can use the scene-related features “Map size X” and “Map size Y” to compute extent information (i.e. area). If not, please le me know what kind of frame do you mean.

Cheers,
Christian

Hi Christain, no I mean the frame in the GUI. So the area that is visible to the user at any given zoom level. My understanding is that Map size Y provides the extent of the entire scene and not only the area that is visible.

Wonderful, I thought it was about something completely different. 😊

You are right, the visible extend of a View in eCognition is not available as a (scene) feature. You can just visually check the View coordinates in the lower left part of the eCognition GUI (using the mouse cursor):

I would say, this is a feature request.

Hi Christian, yes this feature would be very useful. The use case is that I am working on DSM to DTM conversion (DSM is from photogrammetry, not LiDAR) and want to zoom to a certain area, manually reclassify surface objects (e.g. buildings) that were incorrectly classified as ground, then I want to set up a region that is the size of the area that I am looking at and run a range of processing-intensive processes (e.g. segmentation and layer arithmetics that removes the surface objects) within that region only. Then I want to inspect the result and only when I am happy save the result to the scene. That way I do not have to run the processing-intensive rules for the intire scene every time I want to interactively visualize the impact of reclassifying my objects. Unless there is a other/better way of doing this?

Hi Adriaan - I have added to our feature request list! We should get to it in the next release phase.

All the best, Keith

Thanks for sharing the valuable information. All the best
