How to view and save training sample AOIs from a previous IMAGINE Objective project.

by sbent on ‎01-05-2018 02:17 PM (712 Views)


After opening an existing feature extraction in IMAGINE Objective a user may have difficulty viewing the AOIs that were used to collect training samples. They may also want to save the training sample AOIs to a file separate from the feature project file.


To view a training sample AOI, the first thing to do is open the Training Sample Viewer.

IMAGINE Objective Workstation > View menu > Show Training Sample Viewer

Next, select the Training tab and click in a cell under the exclusive selection column (i.e., the ">" column directly on the right side of the Sample column) and it will display the selected training sample and the AOI in the Training Sample Viewer. 


To save a training sample AOI, use the steps outlined above to display the AOI in the Training Sample Viewer first, then click on the AOI to select it. Next, right-click in the Training Sample Viewer and choose Arrange Layers from the Training Sample View menu. In the Arrange Layers dialog you should be able to right-click on the AOI layer and choose Save Layer to save that AOI polygon to a .aoi file.
