Geometries
There are three types of geometry within 1Validate: points, lines and areas.
Each can be defined in terms of its dimensions, and if it has an interior, exterior and boundary.
| Geometry | Dimensions | Interior | Exterior | Boundary | Description |
|---|---|---|---|---|---|
| Point | 0 |
|
|
|
A point is a 0-dimensional geometry that has an interior and an exterior, but no boundary. |
| Line | 1 |
|
|
|
A line is a 1-dimensional geometry that has an interior, an exterior, and a boundary. |
|
|
If the line is a closed ring, there is no boundary (as the boundary is at the end points of a line). |

| Area | 2 |
|
|
|
An area is a 2-dimensional geometry that has an interior, an exterior, and a boundary. |
Note: For multi-part geometries, the interior or boundary is the union of the interiors or boundaries of all parts.
