Crime demos is collection of apps that demonstrate some of the things you can do with the open crime data we publish in a world-readable Cloudant database. There's also a documented public API for accessing the data programmatically.
Crime Browser: A simple point data browsing app that uses an adjustable circle as a "window" on crime data
Crime Visualization: A more complex app that queries crimes based on a polygon you draw, providing summary statistics for those crimes selected by the polygon. It also allows a user to adjust the query's time of day.
The applications use this Bluemix service:
- a Node.js runtime
The fastest way to deploy this application to Bluemix is to click the Deploy to Bluemix button below.
Don't have a Bluemix account? If you haven't already, you'll be prompted to sign up for a Bluemix account when you click the button. Sign up, verify your email address, then return here and click the the Deploy to Bluemix button again. Your new credentials let you deploy to the platform and also to code online with Bluemix and Git. If you have questions about working in Bluemix, find answers in the Bluemix Docs.
Clone this repository then run npm install to add the Node.js libraries required to run the app.
Then run: $ node app.js
The Crime demos web application includes code to track deployments to Bluemix and other Cloud Foundry platforms. The following information is sent to a Deployment Tracker service on each deployment:
- Application Name (
application_name) - Space ID (
space_id) - Application Version (
application_version) - Application URIs (
application_uris)
This data is collected from the VCAP_APPLICATION environment variable in IBM Bluemix and other Cloud Foundry platforms. This data is used by IBM to track metrics around deployments of sample applications to IBM Bluemix. Only deployments of sample applications that include code to ping the Deployment Tracker service will be tracked.
For manual deploys, deployment tracking can be disabled by removing require("cf-deployment-tracker-client").track(); from the end of the app.js main server file.
