# Geometry Types

The following Geometry types can be specified in a feature or mapping request:

Name | Description |
---|---|

Point |
An (x,y,z) location. |

MultiPoint |
The collection of point geometries. |

Polygon |
A geometry consisting of exactly one exterior ring and zero or more interior rings. Each interior ring represents a hole completely inside the area defined by the exterior ring. Polygons with self-intersections or overlaps are not supported. |

MultiPolygon |
The collection of polygon geometries. |

Envelope |
An envelope is a rectangle defined using two points (i.e., lower-left and upper-right) whose sides are parallel to the coordinate system axes. An envelope can be used as the bounds for map rendering, or as a minimum bounding rectangle for enclosing a geometry. |

Ring |
A closed curve of line strings. |

LineString |
An ordered collection of points connected by straight lines. |

Curve |
An ordered connected sequence of line strings. |

MultiCurve |
An unordered collection of zero or more curves. |

LegacyText |
Text that is of MapInfo native table type. |
