Geospatial Query at Google App Engine Datastore
I read the following post Querying Geopt with Objectify This is exactly what I need for my application. At the end of the post I read that the Geospatial Search is in alpha stadium but the post is already one year old. I cannot find any information about the status of Geospatial Queries at Google App Engine. Is it still in Alpha stadium or can I use in production?
so for everyone who is interested in: today 27. Jan 2017 Geospatial Queries are still in Alpha stadium. You need to create a search index of mode geospatial for your Geo Point Property and this is not allowed
I think what you are looking for is the Search API which has (limited) support for querying geopoints e.g. "distance(survey_marker, geopoint(35.2, 40.5)) < 100"
