What I am trying to do, broadly, is delete geopoint A from a DB collection of geopoints if the app user is at geopoint A.

My approach:
Use geolocation service to store user's lat and lng in local storage
Use lat and lng from local storage to feed a query of the DB and return the _id of the geopoint they are at (if it matches one in the DB)
Use the _id to delete the geopoint via a delete service.

My problem is with the DB query service. I can query the DB for strings, but I don't know how to query using geopoint data.

Anyone have any pointers please?
Thanks

Hi thanks but I think those are too advanced - I just want to know if it's possible to query a DB, searching for gepoint data and returning corresponding data.

I know how to search for a string and return other data, but using the same approach doesn't seem to work for gepoints?

Hi Ben,

You can search for geopoint with query service parameter same as other.
Your problem based on passing value to compare and search.
Sometimes geoservice can send value like 42.23314133333 , where the last four '3' are not used in the targeting, but this number can be different to 42.223141 , so try to use at least sphere with value 1 or other small value to recognize your user's position.
