 ====== TerraAIDA Operators Documentation ======
+Operators reference version: 1.0.5
+InterIMAGE is a multi-platform framework, written in C++, currently with implementations for LINUX and Windows operational systems. Moreover, InterIMAGE provides support for the integration of image processing operators in the interpretation process and, as such operators are treated as external programs by its control mechanism, they can be coded in any computer language, and even in proprietary programs. The InterIMAGE framework offers, nonetheless, a repository of operators, called TerraAIDA ([[http://www.dpi.inpe.br/terraaida]]), assembled with software classes and functions supplied by the [[http://www.terralib.org/|TerraLib]] library.

+**Description**
+Allows to export the bottom-up hypothesis (including its attributes) to a shape file. This operator acts like the generic bottom-up operator, making a copy of every hypothesis to the shape file. No spatial conflict resolution is performed when there is no decision rule.
+**Type**

+**Applies to**
+Root (scene) and internal nodes.
+**Multi-Class support**
+No.

+Yes. You must create the same number of classes as the training file. The classes must have also the same name of the training file. One of the nodes must have this operator, and all others should have "No Operator" for Top-Down and Bottom-Up options, and must have the option "Multi-Class" selected as well.
