Spatial Detection - When an unprocessed record with no related entities is opened, the system will automatically search for other records within a short distance. If records are found, we will try to determine if there is a common Case related to other records at this location and suggest to the data manager that this new record might be an update to an existing case.

Yes, that sounds exactly what they would need.

task 1 - new button for spatial search on the record view
task 2 - spatial duplicate check on create new entity dialog
task 3 - Query Entity Observations (same as record query basically)

Task 1 - Added a new spatial entity query that searches for entities based on either a user specified point location or all the locations in an open record. Note that this only searches the entity spatial attributes (it does not search for records associated with entities).

Image not found...

Task 2 - we will not implement this for now - we will review this request after getting feedback from the users.

Task 3 - a new query type that searches entities based on records, record attributes. and record observations. The results displayed are a table that lists all the entities and their attributes that match the filter

Implemented New Entity Query Type that queries records or observations for entities

Where is the new Query for task 3? I can't see it in A.16 but maybe it isn't on the main profiles menu with the other 2 query types?

I think I forgot to put it in the menu - I always access it from the query view. In the toolbar at the top there are three buttons (one for each query type).

I added to the main menu.

all working as expected now in a.17
