When stored in geodatabase format, these four feature classes are organized in a feature dataset named TOWNSSURVEY, which includes the TOWNSSURVEY_Topology rules have been created to enforce spatial relationships among the POLY, ARC and PT layers. TOWNSSURVEY_PT - Points representing survey points.TOWNSSURVEY_ARC - Lines representing municipal boundaries and coastline.TOWNSSURVEY_POLYM - Multi-part polygons representing inland and offshore areas, with one feature for each of the state's 351 municipalities.TOWNSSURVEY_POLY - Polygons representing inland and offshore areas.This layer comprises four separate feature classes:
