Confluence Retirement

In an effort to consolidate USGS hosted Wikis, myUSGS’ Confluence service is scheduled for retirement on January 27th, 2023. The official USGS Wiki and collaboration space is now SharePoint. Please migrate existing spaces and content to the SharePoint platform and remove it from Confluence at your earliest convenience. If you need any additional information or have any concerns about this change, please contact Thank you for your prompt attention to this matter.

  1. Kevin Gallagher
    1. The CDI is more important than ever in maintaining connection and communication.
    2. Virtual collaboration
      1. Do you have a "virtual water cooler"? Microsoft Teams and the CDI wiki are possible places for these kinds of conversations.
      2. Share notes and highlights after virtual meetings so others can benefit from your activity. CDI collaboration areas are great for these kinds of notes.
      3. Share your tips, tricks and ideas for working virtually with the CDI.
  2. Tim Quinn
    1. CDI is "collaboration on a massive scale", and very important in this time.
    2. EarthMAP
      1. Feedback from CDI has been passed onto the EarthMAP team and allowed the team to identify what aspects of EarthMAP are most exciting and most confusing.

  5. Open-source and open-workflow Climate Scenarios Toolbox for adaptation planning: Aparna Bamzai-Dodson
    1. Link to website:
    2. Scenario planning - a way to consider the range of possible outcomes; 3-5 plausible divergent scenarios. Managers and scientists can use this information for adaptation strategies.
    3. The Climate Scenarios Toolbox is attempting to take the pain out of working with climate data
    4. The Toolbox is open and usable, allowing other users to contribute open code. The Toolbox hopes to do the following:
      1. lower the barrier to entry
      2. automate common tasks
      3. reduce the potential for errors
      4. empower a larger user community
    5. The link above includes a getting started guide for the Toolbox.
      1. There is extra support for the National Park Service, as NPS was a partner for this project.
    6. Engaging CDI
      1. Install and use the Toolbox
      2. Provide feedback on issues/features
      3. Contribute to the package
  6. Develop Cloud Computing Capability at Streamgages using Amazon Web Services GreenGrass IoT Framework for Camera Image Velocity Gaging: Frank Engel
    1. Gaging (measuring water quanitity)
      1. Sometimes we can't measure
        1. flashy regimes
        2. unsafe/unreachable
        3. indirect (post flood) methods aren't cheap
    2. How do we get past these issues?
      1. non-contact methods
        1. imagery combined with software - gets complicated; requires training; and some subjectivity is involved
        2. want to automate this process and take some of the pain out of it
    3. CHS/AWS IoT Cloud Processing Goal
      1. First required building a cloud infrastructure
      2. Successes
        1. Auto-provisioning to the cloud
        2. MQTT Schema (in progress)
        3. Generating global actions (see something, do something)
        4. Initial time-lapse video Lambdas (for SSTL)
      3. Lessons learned
        1. Cloud computing knowledge takes a lot of work to acquire
        2. A lot of hands in the cookie jar
          1. In the short term, it can be difficult to sort through the differing needs of stakeholders
        3. Time!


  1. Based on recent USGS guidance, will this call be moved off of Zoom to Teams?
    1. Leslie: We are testing external participation now and will keep the CDI informed of tech choice. Anyone interested in testing or discussing further, get in touch with me!
  2. Would you be able to see if you have any "surprising" new users as a result of the tool, or do you have ideas of how to learn if you do?
    1. The package is not officially released on GitHub but we are working on it, and there will be a publication in Journal of Open Source Software. Hope we see people fork code, can incorporate user modifications back into the main branch. Hoping the user community picks this up and makes it into a bigger and better toolbox.
  3. What was your process for identifying your main users and their needs?
    1. Our center is part of a USGS network meant to work with natural resource management partners to help understand climate adaptation science. Work quite extensively with Fish and Wildlife Service and National Park Service over 7 years on supporting their science needs. Saw inefficiencies in the workflow. Commonalities in data requested, but starting from the ground up whenever having to provide it. Anyone doing research across continental US can use it, so hoping to expand past initial stakeholders
  4. Is the climate reanalysis data included so that historical climate (and weather) can be downloaded too?
    1. Yes, it can do historical and future comparisons.
  5. Could you say more about the Journal of Open Source Software?
    1. Open review process; way to release new tools that are allowing people access to new data. Write-ups for publication are pretty short; description of the package/software, what problem it solves, and how you are contributing (not doing something that is already done). Goes through peer review process and is released as a publication. Nice way to get the tool out to a broader community.
  6. Is it possible to include a vignette that uses the software in a JOSS publication?
    1. Will find that out and get back to you.
  7. Is "edge computing" the same as "data proximate analysis"? Can you explain it a bit more?
    1. No (don't know what data proximate analysis is). Edge computing is putting some sort of internet-connected device (like RaspberryPIs) at the edge, in the environment its meant to be in. Camera on the bank of a river. Phone in your pocket, etc.
  8. Can a user trigger the camera remotely? Or, based on water surface elevation?
    1. Yes. You can trigger the RaspberryPI to record video based on an external trigger. If it's an internet-connected PI, you can query another streamgage or other sensor and trigger that way. In the process of testing some other methods.
  9. How do you handle security with IoT? Are these RaspberryPIs protected since they have AWS credentials to upload the data? Is there a DMZ for video uploads?
    1. We are developing a stig for RaspberryPIs. Enforce how people set up modems in the field so its unreachable from the outside world.
  10. Are you using raspberri Pi camera?
    1. Yes. We use many different cameras. Rely on security web cameras that are NDAA compliant cameras.
  11. Can you elaborate a bit on Infrastructure as Code practices you're using for this IoT project? You mentioned that you had to create infrastructure first
    1. Foundry is the infrastructure. Code is Python-based.
  12. How many IoT RPis cameras are there. Do they provide constant video feed?
    1. Two cameras enabled IoT. 20-40 connected cameras not on IoT.
  13. Is that RPi stig available anywhere?
