Aggregation The spatial object being reported is the result of the spatial aggregation of two or more existing spatial objects, and replaces the previously reported objects (i.e. the objects being aggregated). Change The spatial object identifier has not changed since the object was last reported. Minor changes to the geometry are reported (e.g. minor adjustments to the delineation or locations, improved geometry resulting from a new spatial data source, etc.), or updates to other attributes. Change due to both aggregation and splitting The spatial object being reported is the result of the combined spatial aggregation and splitting of two or more existing spatial objects, and replaces the previously existing objects (i.e. the objects being aggregated and/or split). Change in the identifier The spatial object being reported replaces a previously reported object, simply due to a change in the identifier. Minor changes to the geometry can be reported (e.g. minor adjustments to the delineation or locations, improved geometry resulting from a new spatial data source, etc.). Updates to other attributes can also be reported. Note that the previously reported object will be flagged for 'deletion' and is replaced by the newly report object. Change due to extended area The spatial object identifier has changed since the object was last reported. Relevant changes to the geometry are being be reported, which result in an increase of the area of the object. Updates to other attributes can also be reported. Change due to extended area and depth The spatial object identifier has changed since the object was last reported. Relevant changes to the geometry are being be reported, which result in an increase of the area and depth of the object. Updates to other attributes can also be reported. This option can only be applied to groundwater bodies. Change due to extended depth The spatial object identifier has changed since the object was last reported. Relevant changes to the geometry are being be reported, which result in an increase of the depth of the object. Updates to other attributes can also be reported. This option can only be applied to groundwater bodies. Change due to reduced area The spatial object identifier has changed since the object was last reported. Relevant changes to the geometry are being be reported, which result in a decrease of the area of the object. Updates to other attributes can also be reported. Change due to reduced area and depth The spatial object identifier has changed since the object was last reported. Relevant changes to the geometry are being be reported, which result in a decrease of the area and depth of the object. Updates to other attributes can also be reported. Change due to reduced depth The spatial object identifier has changed since the object was last reported. Relevant changes to the geometry are being be reported, which result in a decrease of the depth of the object. Updates to other attributes can also be reported. Creation The spatial object being reported is new and does not replace any previously reported objects. Deletion The spatial object being reported is no longer in use. Depending of the specific case, the object may be replaced by other objects (e.g. if it was split), or it may simply be retired (in which case it it will have no successors). No change The spatial object identifier and geometry have not changed since the object was last reported. Updates to other attributes can be reported. Splitting The spatial object being reported is the result of the spatial splitting of one existing spatial object, and replaces the previously reported object (i.e. the object being split).
