Table of songbird boundaries

You may view and manipulate the boundary table by choosing "Table" from the "Project" Menu or from the pop-up menu from the project window Boundary tab.

The local warbler boundaries table lists the x and y coordinates of the candidate Boundary Element points (cBEs), the Boundary Membership Value for each cBE, the Boundary Likelihood Value (BLV) for each cBE, and the BLV (gradient magnitude) and gradient angle for the local warbler boundaries.

The BMV indicates whether the cBE is in the boundary (BMV = 1) or not (BMV = 0). You set the criteria for boundary membership in the wombling dialog by setting the threshold to the top 17% of BLVs.

In cases such as this one, where multiple variables were used to define the boundary, gradient magnitudes and angles are listed for each variable in the table.
