MONGODB SPATIAL



SPATIAL NOTESMongoDB currently supports the following types of

spatial queries1 Near2 Containment

MongoDB GIS summaryhttpwwwmongodborgdisplayDOCSGeospatial+Indexing



MONGODBASSUMPTIONS

Assumes coords are between -180 and 180Can handle any 2D coordinatesHas methods to handle curvature of the earth(spherical)



MAKING IT WORK1 Put your data in an array

2 Add a 2d index to your collection

loc [ 50 30 ] SUGGESTED OPTION loc x 50 y 30 loc foo 50 y 30 loc lon 40739037 lat 73992964

dbplacesensureIndex( loc 2d )



GEARING UP A NEW APP ON OPENSHIFTor

rhc app create APP_NAME APP_CARTRIDGE

RESULTApplication parks was created



Adding mongodb-22 to application parks Success

mongodb-22 (MongoDB NoSQL Database 22)---------------------------------------- Connection URL mongodb127610212927017 Database Name parks Password T5xJwCiDZYGn Username admin

RESULTAdded mongodb-22 to application parks



SUCCESSYou now have a basic nodejs app up an running on

OpenShift

Your gear is now configured with

its own git repoits own web serverMongoDBssh accessloggingpublicly accessible DNS



BUILDING YOUR APP cd parks



SETTING UP MONGODB ON OPENSHIFTrhc cartridge add mongodb-22



INSTALLING DEPENDENCIESUsing Nodes

Include the -S flag in order to save this dependency toyour applications packagejson file

npm package managernpm install mongojs -S

httpnpmjsorgpackagemongojs



COMMITTING YOUR CHANGESCommit your changes locally

git add packagejson serverjs

git commit -m adding mongojs npm dependency initializing mongojs library adding a basic API



DEPLOYMENTDoneYour spatial app should now be live IN THE CLOUD

git push



ROCKMONGO ON OPENSHIFT(optional)

rhc cartridge add rockmongo-11



CONNECTING TO MONGODBvar mongojs = require(mongojs)var connection_string = bot_nameif(processenvOPENSHIFT_MONGODB_DB_PASSWORD) connection_string = processenvOPENSHIFT_MONGODB_DB_USERNAME + + processenvOPENSHIFT_MONGODB_DB_PASSWORD + + processenvOPENSHIFT_MONGODB_DB_HOST + + processenvOPENSHIFT_APP_NAMEvar db = mongojs(connection_string [scoreboard])



SSH TO THE CLOUDFIND YOUR APPS SSH ADDRESS

SSH IN TO YOUR OPENSHIFT GEARrhc app show parks

rhc ssh -a APP_NAME



IMPORTING YOUR DATAmongoimport -d parks -c parkpoints --type json --file $OPENSHIFT_REPO_DIRparkcoordjson -h $OPENSHIFT_MONGODB_DB_HOST -u admin -p $OPENSHIFT_MONGODB_DB_PASSWORD



ADDING A 2D INDEXCONNECT TO MONGODB CLI

SELECT YOUR COLLECTION

ADD THE 2D INDEX

mongo

use parks

dbparkpointsensureIndex(pos2d)



SPATIAL QUERIESFINDING POINTS NEAR hellip

FIND BY NAME (REGEX)

GEONEAR

dbparkpointsfind(pos $near [-37 41])

dbparkpointsfind( Name lincolni pos $near [-3741] )

dbrunCommand( geoNear parkpoints near [-3741] num 10 )



ADDING CHECK-INSCREATE A NEW COLLECTION FROM SCRATCH

INSERT A NEW RECORD

QUICK QUERY TO MAKE SURE IT WORKED

dbcreateCollection(checkin)dbcheckinensureIndex( pos 2d )

dbcheckininsert( created new Date() Notes just landed pos [-767302 255332 ] )

dbcheckinfind( pos $near [-3741] )



ADD A SECOND DOCUMENT CLOSER TO QUERY POINTTHIS IS AN UPSERT - SINCE WE DONT PASS IN THE _ID IT CREATES A NEW RECORD

ONE WAY TO UPDATE ORIGINAL DOCUMENT

dbcheckinsave( created new Date() Notes that was a big step pos [-377302 405332 ])

myDoc = dbcheckinfindOne(_id ObjectId(50130d8ea8f6532e83026bc1))myDocNotes = really the landingdbcheckinsave(myDoc)



CONCLUSIONS1 Spatial on MongoDB is easy and fun2 You can now build your own FourSquare or other

checkin application3 You can also build your own field data entry system4 You can build and deploy your application quickly

without having to think about infrastructure
