n a union analysis, all input feature classes and feature layers must have polygon geometry.Group of answer choicesTrueFalse

In a union analysis, the requirement that all input feature classes and feature layers must have polygon geometry is True. Union analysis is a geospatial operation used in Geographic Information Systems (GIS) to combine multiple polygon layers into a single output polygon layer. This operation maintains the geometric and attribute information from all the input layers. If any of the input layers were not polygons (for instance, if they were point or line geometries), the union operation would not be valid, as it is specifically designed to work with polygonal data. Thus, ensuring that all features have polygon geometry is essential for the successful execution of a union analysis in GIS.
