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.

  3. Serving the U.S. Geological Survey’s geochronological data - Leah Morgan and Amy Gilmer, USGS
    1. Project goal is to bring together and serve USGS geochronological data
    2. National Geochronological Database (NGDB) was last updated in the 90's. There is currently no central, integrated source for this data and new data.
    3. To serve this data, project team is:
      1. Working with collaborators to build a database in a Post-Gres SQL structure
      2. Populating the database with useful data
      3. 3 parallel approaches:
        1. Migrate data from old NGDB database
        2. NAGT USGS intern will manually input data from published literature, first with scientists nearing retirement
        3. Work with University of Kansas and to build APIs to automatically populate data (new data releases as posted to SB)
    4. Database schema model built by Andy Park at Eastern Energy Resources Science Center (see slide)
    5. Schema captures info about each sample (material type, location information, temporal information, etc.)
    6. Schema also captures info about analysis/techniques
    7. Application
      1. Integrating data with the National Cooperative Geologic Mapping Programs Intermountain West Geologic Framework project
      2. Having geochronological data is essential to making comprehensive compilation work
      3. Integration of geochronology with geologic mapping
      4. Geochronological data with critical mineral studies (how it formed, looking for additional resources)
  4. Rocky Mountain Region Science Exchange - Alicia Torregrosa, USGS
    1. Objectives for the Rocky Mountain Science Exchange are exchange of knowledge, cross-center collaboration. 2020 goals were focused on drought, EarthMap and the creation of this new culture, and creating an online presence. 
    2. RMR Science Exchange 
      1. Held entirely on Teams 
      2. 216 attendees and 37 science talks 
      3. SharePoint site has all recordings 
      4. ArcGIS online spatial catalog linked by StoryMap to participant entries 
      5. Internal access only 
    3. Content 
      1. EarthMap set the stage 
        1. Provided background information 
        2. Included Office of Science Quality and Integrity initiatives 
        3. Lightning talks and panel discussions focused on themes of EarthMap and drivers of landscape change 
      2. Colorado River Basin use case presentations (EarthMap pilot project) 
        1. These types of use cases are being solicited by EarthMap - submit if you have a use case. 
        2. This pilot evaluates and predicts impacts of severe drought on earth system components. 
      3. One objective was to gauge knowledge of EarthMap - participants in the workshop had a stronger understanding after workshop ended. 
  5. CDI Pop-up Lab
    1. Using Git - an interview - Richie Erickson, USGS
      1. (see slide for full details) 
      2. Git helps with version control (what got changed, when, and by who) 
      3. Allows code to be put in the cloud 
      4. Git is an open source tool that is free; there are also commercial vendors like GitLab 
      5. Git project homepage has several nice video tutorials. Software carpentry also has nice tutorials. 
      6. Richie has also gathered tutorials as a part of a CDI project. Come to the December CDI monthly meeting to learn more. 
      7. CDI calls are a great spot to see what others are using. 
    2. Remote Sensing Forest Classification for Timber Appraisal - Joe Adams, USGS
      1. (see slide for full details) 
      2. Pain point: appraising land that has timber on it. 
      3. FRASS (forest resource analysis system software)  
      4. PoTree Viewer: 
      5. Trimble presentation tomorrow

Questions & Answers

  1. Does the interaction with the National Geologic Map Database allow the Geolex data (geologic fm names) to join the geochron data?
    1. No, we have not integrated.
  2. Was there anything that was new or difficult ot fit into the schema based on newer ScienceBase Data releaseas?
    1. Flexible approach - schema will need to add info later
    2. Varying levels of info in new data vs old data
    3. Several levels of geochronological data; age for one sample or one formation (parent child relationships can incorporate all these data)
  3. Will guidance be released?
    1. Working with geochronologists who are actively collecting data - schema reflects data release structure. Will provide documentation to capture that information
  4. Do you have a tentative timeline for rolling out a publicly-accessible version?
    1. No timeline as of now.
  5. Are you keeping a link to the ScienceBase item in your database so if someone wants to get back to the original data they will be able to do so?
    1. Yes. Also keeping links for older publications that have been incorporated but do not have a ScienceBase data release
  6. Who can I contact at KSU (?) about the SB harvesting scripts?
    1. Working with Noah McClean in the geology department and Jason Ash
  7. Updates on the geochronological database effort?
    1. Contact Leah Morgan or Amy Gilmer
    2. Within next year, hope to have an interface begun through the National Geologic Mapping Database project
  8. Do we have access to the EarthMap SharePoint site and the primer video? If so, can we share the link in this chat or are the slides available some place?
    1. Yes.
    2. RMR SharePoint:
  9. Do you have any tips for holding a large virtual meeting?
    1. Much more work than you think. Did not bring on IT support soon enough. Made heavy use of OneNote. ArcGIS Online and the Power Flow in O365 were useful. Did lots of dry runs to get everything working correctly. Challenge with overloaded Microsoft servers, so were encouraged to record the presentations with another program like Camtasia. The screen capture did not always work.
  10. Can you quickly cover using Git vs Jupyter? Pros/cons?
    1. Two different things. Git keeps track of code, can use with any plain text code. Jupyter is an interactive way to work with code. Jupyter = Microsoft Word; Git = SharePoint. Jupyter is part of the conda project, and they have their own way of sharing things.
  11. Is there a write-up anywhere of this RFP / need?ere a write-up anywhere of this RFP / need?
