The spatial functionality MongoDB provides
1) near
2) within
All of it is laid out on one page:
http://www.mongodb.org/display/DOCS/Geospatial+Indexing
First link on Google for “MongoDB spatial indexing”
Spatial is fun!

1) Put your coordinates into the document
{ loc : [ 50 , 30 ] } //SUGGESTED OPTION
{ loc : { x : 50 , y : 30 } }
{ loc : { foo : 50 , y : 30 } }
{ loc : { lon : 40.739037, lat: 73.992964 } }
2) Make a 2d index
db.places.ensureIndex( { loc : "2d" } )
How to make it work

11. 11
1. Demo MongoDB command line
2. Demo the expected result
3. Create an OpenShift application
4. Import the code from Github
• https://github.com/openshift-quickstart/spatial-ruby-openshift-quickstart
5. Demo the deployed application
Demo

12. 12
1. Spatial is easy and fun on MongoDB!
2. You can now build your own FourSquare
