MongoSF - Spatial MongoDB in OpenShift - script file
0 likes371 views
This document provides instructions for adding spatial data to MongoDB. It details how to import a JSON file containing coordinate data into a MongoDB database hosted on OpenShift, build a 2D index on the coordinate field, perform spatial queries to find documents near a given location, insert new documents with location data to new and existing collections, and update the notes field of an existing document.
