Until version 1.3.1-Barbarian, when an ontology was created and the user wanted to use Geospatial Information, it was possible to define a field type as geometry, being able to store in this field the longitude and latitude of a point, following the GeoJSON standard.
However, if the user wanted to introduce another type of geometry, such as lineStrings or Polygons, he/she had to manually modify the Ontology Scheme and adapt the geometry schema from Point type to LineString or Polygon type, with the annoyance that this is supposed to the user.
Therefore, from 1.3.1-Barbarian-RC2 the range of possibilities is extended when selecting the type of geometry to be used, being able to choose between the following:
- Points
- MultiPoints
- LineStrings
- MultiLineStrings
- Polygons
- MultiPolygons
Types of vectorial geometries
Would you like to know more about each type of geometry? Take a look at the GeoJSON Draft Appendix, where examples are shown for each type of geometry.
Thanks to this improvement, it's possible to define in a fast and efficient way the needed Geometry Scheme for each case. For example, in the case of a Polygon Geometry, when making the CRUD of the Ontology it's possible to set the multiple coordinates quickly and easily.
When the user wants to generate a Layer from the Ontology in My GIS Layers, choosing the geometry field will directly recognize the geometry defined for the property.
Finally, when the layer is represented in a map through My GIS Viewers, the polygon is perfectly represented from the coordinates provided.
