Introduction

Alerthub builds on ​SAMBRO and the Messaging module. One can configure the Alerthub to receive messages through CAP, RSS/Atom, Twitter, Facebook news feeds to, then, aggregate all those alerts for various information needs. It is intend to serve as a ​one-stop-shop for all your alerts. The alerts will be classified for the ease of filtering and drilling down into desired sets of spatial and temporal data. Moreover, the classification and other statistical analysis will provide insightful information for improved ​cross-agency situational-awareness.

Requirements

  1. Register an alert feed as CAP, RSS/Atom, and Twitter
  2. Stage them in a database and sanitize the data for processing
  3. Develop various views and APIs mainly for
    1. generating exports in CSV and JSON formats
    2. automation (e.g. extracting data for running the classifier)
  4. Implement standard EDEN reporting tool for generating cross-tabs and charts for SAMBRO Alerthub data.
