IS-GEO Boulder 2019


IS-GEO Workshop 2019

IS-GEO aims to achieve the following goals:

  1. Foster and grow a community across Intelligent Systems (IS) and GEO
  2. Identify barriers to research and establish mechanisms to overcome them
  3. Establish and enhance communication channels between GEO and IS researchers
  4. Identify grand challenges for an IS-GEO research vision
  5. Encourage robust, long-term collaborations between GEO and IS researchers
This is the agenda for the 2019 IS-GEO workshop.

Cloud-Hosted Realtime
Data Services
for the Geosciences

CHORDS is supported by the National Science Foundation EarthCube initiative, which is a community-led cyberinfrastructure initiative for the geosciences.

You are looking at a CHORDS Portal. This is a web service that allows scientists to easily provide Internet access to real-time streaming data. Typically these data are measurements made by diverse instruments, which are deployed in support of a particular research effort.

Each research team can operate their own portal, which is created simply by running a copy of the CHORDS appliance on Amazon cloud services. This provides a web server and database. CHORDS can both ingest and deliver data via simple http: requests, just like any web browser. Configuration and management of your private CHORDS server is also done through a web interface. Any user on the Internet can attach to the data streams using tools of their choice, such as Matlab, Excel, Python, web browsers; i.e. anything that is able to issue an http: request.

CHORDS portals can also forward real-time data streams to higher level CHORDS services, which might provide functions such as OGC compliant formatting, mapping services, federation, and just about anything else you can think of.

The goals of CHORDS are:
