Spatial extent

1 Definition

The zone or region of space described by a geographic identifier in the form of a label or code, or by a bounding box. It consists in the maximum extent (the spatial boundary or limits) within which the user is requesting data.

The attribute represents the maximum spatial extent of the AOI, and in case the AOI is made of many discontinuous zones then it represents the maximum extent of the union of all the zones.

Notes

  • WIGOS metadata standard defines it as the typical spatial georeferenced volume covered by the observations

Examples

  • if a user is requesting information about degradation of African protected sites, then the AOIs are the protected sites, and the spatial extent is the African continent.
