The Split_IsHole column is generated under which condition in the Poly-Split tool?

The Split_IsHole column is generated when splitting into detailed regions, which indicates that the polygon being split has a hole. When using the Poly-Split tool, if a polygon contains a hole, this column helps to identify whether the resulting split areas include that hole. In geographical information systems and spatial data processing, holes refer to areas that are completely enclosed by the outer boundary (the main region), and acknowledging their existence is crucial for accurate data representation.

This column provides valuable information to understand the topology of the split regions. For instance, if you have a polygon that represents a lake with a hole representing a small island, the generation of the Split_IsHole column allows users to differentiate between the exterior boundary and interior features, ensuring that analyses like area calculations or map rendering are done correctly.

The other conditions mentioned, such as splitting into points or lines, do not inherently involve the concept of holes in the same way that splitting detailed regions does. Consequently, they do not necessitate the creation of a Split_IsHole column, as the nature and characteristics of the output do not involve enclosing regions.
