The value displayed in the RELATIONSHIP_TYPE field indicates the best available information about how a relationship was created:

 Type Description 1 RELATION DETERMINED VIA GEOCODING If two features both have addresses, Precisely parses and standardizes these addresses and uses geocoding technology to assign a PreciselyID (PBKEY). When two PreciselyIDs match, a relationship can be created. 2 RELATION DETERMINED VIA MULTI-TIERED SPATIAL ANALYSIS If two features are in spatial proximity to one another, they can be compared to one another using multiple techniques such as distance, enclosure, shape, etc. This value will be set if a relationship was made using one or more of these techniques. 4 SPATIAL RELATIONSHIP – PRIMARY KEY ENTIRELY WITHIN SECONDARY KEY This technique is used when the secondary key is represented by a geometric shape with an area. If the primary key, regardless of whether it is a point, line or polygon, is fully contained within the secondary key’s geometry then this value is set. 8 SPATIAL RELATIONSHIP – PRIMARY KEY PARTIALLY WITHIN SECONDARY KEY Like value 4, this technique is used when the secondary key is represented by a geometric shape with an area. In this situation the amount of overlap of the two features is compared. If it is determined that the overlap meets Precisely’s rules for meeting or exceeding minimal overlap then this value is set. Note that it is valid for both this and the 4 value to be set. Also note that this value is not used when the primary key is a point feature as it will overlap entirely or not. 16 RESERVED FOR FUTURE USE 32 RELATIONSHIP DETERMINED VIA GEOCODING GENEALOGY In some cases, addresses can be unique but still reference the same location or proximity. When multiple addresses are related in this way, this value is set. 64 SPATIAL RELATIONSHIP – SECONDARY KEY ENTIRELY WITHIN PRIMARY KEY If the object referenced by the primary key is represented by a geometry shape with area, this value is set if the secondary key is completely contained by the primary key. 128 RELATIONSHIP BASED ON MUTUTAL ATTRIBUTE DEPENDENCIES Relationship created on the basis of two like attributes in separate foundational products (for example, linkage of parcels to property attribute points via the PLINKID field)
