#Neon Geo Temporal Dashboard The Neon Geo Temporal Dashboard (neon-gtd) is a sample analysis dashboard built upon the Neon Framework. It includes a number of geo-spatial and temporal data visualizations built as AngularJS directives that use the Neon framework to query and filter data served by MongoDB, Elasticsearch 1.7 or an Apache Spark server.

Neon is a software platform designed to help developers integrate disparate visualization widgets with your data stores. It includes a Data Access API that makes it easy to query an underlying database directly from JavaScript or RESTful endpoints. Additionally, the Neon Interaction API provides capabilities for inter-widget communication and shared data filters, allowing multiple visualizations to interact without being explicityly aware of one another.

Build and run the example

Building the neon-gtd application requires npm, grunt, and bower. Running the application requires a functioning Neon deployment. Links to the Neon deployment instructions and the command line instructions to build neon-gtd follow:

  1. Build and Deploy a Neon server or simply drop the latest neon.war in a web application container such as Tomcat.

  2. Clone the neon-gtd repo

     git clone
     cd neon-gtd/
  3. Copy the sample NEON-GTD configuration file to the app config folder or supply your own. The configuration file specifies the default datasets and visualizations to display. It is described in detail here. The sample configuration file is setup for the sample earthquake data referenced in step 1.

     # Copy either the YAML or JSON config file.  If Neon-GTD cannot find one, 
     # it will look for the other.  
     cp app/config/sample.config.yaml app/config/config.yaml
     cp app/config/sample.config.json app/config/config.json
  4. Use npm and grunt to download dependencies and build the application. This will create a neon-gtd war file in the neon-gtd/target directory.

     npm install
  5. Deploy the neon-gtd-<version>.war file to your container from step 1. Note: On Tomcat, this may be as simple as copying the file to your /webapps folder. Optionally, you may want to rename the war file to be simply neon-gtd.war.

  6. If running against a stock, localhost Tomcat instance, browse to the http://localhost:8080/neon-gtd/app/ to verify its installation. The Users Guide describes its basic use.
