  • Points - Defines point features or area features represented by a point that are displayed in mapping processes by a symbol.

  • Multi-points that are two or more points that are treated as one feature are supported.

  • Line/Polylines - A chain consisting of a sequence of non-intersecting line segments. A vertex is a change in direction along the length of a line segment or at the end of the line string.

  • Multi-polylines are two or more polylines, not adjoining each other and treated as one feature. 

  • Polygons - A bounded continuous region consisting of an interior area.

  • Area-connected planar polygon with one external boundary are polygons that do not completely cover the interior area of the polygon. A void area within the polygon is not part of the same feature.

  •  Multi-polygons are two or more polygons, not adjoining each other and treated as one feature. Multi-polygons can consist of polygons and holey polygons together.

Table 1 - Feature geometry

  • All polygon boundaries must be closed.

  • Polygon features may contain an inner set of holes or voids that can be assigned to any feature class. For example, a Lake may have in the middle of it an area of dry land (terrestrial island).
