12/19/17, USGS GIS Community

The USGS GIS Community had a discussion on 12/19/17 about how GIS users and enthusiasts at USGS can share information and tools as a community. The importance of the topic was illustrated by the fact that the call was so well attended that we ran out of phone lines (sorry about that - recording linked below.) Shane Wright and Roland Viger led the discussion, including the current state of USGS Enterprise GIS Help. CDI helped to facilitate the call.

Participants answered polls about what open source GIS tools they use, what technical support mechanisms seemed most promising, and what are the most important needs of the GIS community over the next 5 years. This was the start of a community of practice that will help to communicate and advance GIS capabilities at the USGS. To get involved in the conversation, contact Shane (wright@usgs.gov) or Roland (rviger@usgs.gov).

More CDI Blog posts

This post rounds out the 2017 CDI Collaboration Area Activity. It's been such a full year, I'm looking forward to more great topics in 2018!

Some of these topics do not really lend themselves to images, but we must have an image. So here is last month's ball of CDI Collaboration Area words:


11/30 Software Development Cluster - future topics

The group discussed goals to help guide how this group could collaborate and benefit from each other (in order of priority and likelihood):

  • Share awareness of what is going on (software efforts, tool exploration, best practices, metadata standards)

  • Share lessons learned

  • Share configurations (software, tools, architectures, ...)

  • Share data, services, and/or maybe even code

Let the group leads, Michelle Guy (mguy) and Blake Draper (bdraper), know if you have specific topics or goals you’d like to see addressed. Software Development Cluster Page

12/4 Metadata Reviewers - data quality information

The group talked about a specific field in the USGS data release metadata: That pesky data quality information. The Data Quality field is challenging because many metadata creators and reviewers are not sure what to put there, many times there is no useful content in that field. Madison Langseth brought up a current effort to compile Data Quality Documentation Examples. See the rest of the discussion at the Metadata Reviewers page.

12/5 DevOps - streaming data, agile contracts, Cloudfront

DevOps had three presentations, two in Project Management and two in SysAd and Developer.

  • SCAPE (Secure Cloud Analytic Processing Environment): A Framework for adaptable and secure analysis of streaming data. (Ginny Cevasco - Booz Allen Hamilton)

  • GHSC (Geologic Hazards Science Center) experience with an Agile Contract (Lynda Lastowka, USGS). Shared link on agile contracts in government.

  • CHS (Cloud Hosting Solutions) Cloudfront/WAF service (Jonathan Russo - CHS)

DevOps wiki page.

12/11 Data Management Working Group - the business of science

The focus was the Data Management Theme: Acquire. Brian Reece spoke on the topic "Data integration, fiscal accountability, and the 'business of science.'" He presented an evolving suite of web services and procedures that improve the availability to access and integrate data from Bureau systems such as BASIS+ (used to track projects and financial info), FBMS (tracks agreements and sales), and IPDS (used to track publications). Data Management WG page

12/14 Semantic Web Working Group - integrated modeling

The group discussed plans for possible future work on an integrated modeling project and a data dictionary database, as well as content for a future CDI Monthly Meeting. Semantic Web WG page.

12/14 Tech Stack Working Group - more Jupyter widgets

"Mini-Hack-Session: Developing and extending Jupyter Widgets": Jason Grout, Bloomberg. Jason walked through the thought and technical processes involved with developing new widget capability. See the recording. Tech Stack WG page.

12/27 Open Source Coffee Talks - code inventories and metadata

The December Open Source topic was code inventories and metadata. Eric Martinez has been working on leverage open APIs to aggregate code.json files from individual USGS projects into a software inventory compatible with code.gov. Eric was unavailable at this months call. Alternatively, Cian Dawson volunteered to talk about the Water Mission Area activities and the Software IM. The Software IM is currently under heavy revision by the Fundamental Science Practices Advisory Committee and any feedback is welcome. (See details at the first comment on this page.)

Here's another installment of all the topics being explored in the CDI Collaboration Areas. I'll get up to date yet!

11/2/17 Software Development Cluster - How do we use version control?

The Software Development group discussed how people use github or other version control, for example, regarding release schedules and when in the dev cycle do releases begin? Eric Martinez led this conversation with a presentation on how the GHSC (Geologic Hazards Science Center) is using gitlab. Slides available to Dept. of Interior users.

Examples of using GitLab

11/6/17 Metadata Reviewers - learning about different type of specialized metadata - the Biological Data Profile

The Metadata Reviewers group had earlier decided to learn together about different types of specialized metadata. Pai and Erika shared examples of using the Biological Data Profile for data from Sea Otter Surveys. (See Western Ecological Research Center Approved Data Releases) Read more.

Where to go to find Sea Otters... Figure from a publication supported by Sea Otter Survey Data that is documented with the Biological Data Profile.

11/7/17 DevOps - USGS Git Hosting News, Content Delivery Networks

The DevOps meetings continue to bring us explanations of new and evolving capabilities available to groups in the USGS, as well as opportunities for me to learn new acronyms.

    • Intro USGS Git Hosting Platform (Eric Martinez). Slides available to Dept. of Interior users. Questions Comments Feedback: GS Help GIT: gs_help_git@usgs.gov.

    • Announcing CHS CDN/WAF Service  (Cloud Hosting Solutions) (Content Delivery Network) (Web Application Firewall) (Jonathan Russo). This is a managed service intended for people who have a public facing internally hosted site that want to utilize Cloudfront.

    • GIT Hosting and Version Control (George Rolston). George presented code.chs.usgs.gov and gitlab-ci which is currently running and available for use. If you are not aware of what gitlab-ci is, it is a great time to learn how you can automate your builds with nothing more than a commit to master on code.chs.usgs.gov (CI = Continuous Integration)

Access more information at the DevOps wiki page.

11/9/17 Semantic Web Working Group - a USGS triple store

This is the place you can go to learn about user stories for a USGS triple store, picking a system of persistent identifiers for linked data components, and choosing between 303 URIs and hash URIs. We are all learning together!

11/9 Tech Stack Working Group - Jupyter Widgets

"Jupyter Widgets": Jason Grout, Bloomberg. (aka ipywidgets) enables building interactive GUIs for Python code using standard form controls (sliders, dropdowns, textboxes, etc.), as well providing a framework for building complex interactive controls such as interactive 2d graphs, 3d graphics, maps, and more.

See the recording.


11/13 Data Management Working Group - "Plan"

The focus was the Data Management Theme: Plan, and the group welcomed speakers on three topics:

    • Guidance on how to release USGS model output files – Fran Lightsom

    • Examples of building data management plans as code – Sky Bristol

    • Data Management activities in the Water Mission Area – Linda Debrewer

See the slides at the DMWG meeting page.

11/29 Open Source Coffee Talks - estimating software development tasks

Estimating Software Development Tasks. Discussion: "What approach has worked to best determine when a (software development) task will be completed on time, within scope, and within budget? Single point estimating? Three Point Estimating? Story Point Estimating? 50%-90% Estimating? Padding your initial thought by a factor of 2,4,8 estimating?" The group discussed these options and also created a new #projectmanagement slack channel on USGS slack. (If you do not have a Slack account, email Paul Moreland (pmoreland@usgs.gov) and he will get you set up.)

Learn more about the group at their wiki page.

Announcements included some teasers for the FY18 CDI Request for Proposals. We hope to release the guidance for the proposals process in December, you can check out the current proposals page to prepare.

Sophia Liu, who is on Mission Assignment to FEMA, presented on Leveraging Crowdsourcing in FEMA-led Response Efforts.


Colin Talbert showed us some awesome notebook capabilities in the Reproducible Notebook Series: Notebooks as a Data Management Superpower. These included examples of batch metadata propagation and upload, and a way to visualize a summary of a Science Center’s records in the USGS internal publication system.


Demo of an app that shows a timeline and different status for publications in the USGS internal publication system.

Michelle Guy presented on National Earthquake Information Center: Overview real-time data acquisition, processing, and archive.


NEIC data flow.

Lynda Lastowka presented on National Earthquake Information Center: Data-first concept for presentation and delivery.

The data-first approach (providing quality data that can be then used in a variety of ways by users) supports minimum viable products and early adopters. Data is presented for both human and programmatic users. 

See more at https://earthquake.usgs.gov/

Highlights from Q/A:

  • Regarding official USGS data release: Some of the earthquake data presented qualify as web data services. This category was designed for ‘data in motion’. Individual approved data releases are not required.
  • Some advice for other groups looking to improve their data flow for rapid response: Decouple process and presentation. All of their data streams come in and then go into the Derived Product Data Distribution Layer, which is a common communication mechanism for all other processes. The one common communication mechanism is key.
  • What is CI/CD? Continuous Integration / Continuous Deployment. In software development, an automated suite of tests and deployment. If test passes it is automatically pushed to production environment.

Visit the November meeting wiki page for slides, reproducible notebook links, and recording.

At the October 11, 2017 Monthly Meeting, we had our first episode of the Reproducible Notebook Series. These notebooks, rather than being college-ruled and spiral bound, are a web-based interactive computing platform where you can execute blocks of code and view results. In these segments we find examples of notebooks doing useful things (e.g., accessing data from a database and visualizing them) and give you a demo.

Rich Signell, demonstrated his Dust Bowl Notebook. At the link you can click on the .ipynb file to see the notebook, or click the "launch binder" button to execute the notebook!


Daniel Pearson, Joe Vrabel, and Ramona Neafie from the Texas Water Science Center presented "From API to Apps: USGS Texas Water Science Center Web Development Approaches and Analytics."

Topics covered included:

    • Software repository requirements and recommendations

    • Software releases and DOIs

    • Credit for original authors, especially as we work in public domain? We can request, encourage, we cannot enforce.

    • Updates on Code.usgs.gov

Find out more about CDI Collaboration Areas on our wiki.

Q: What's a "collaboration area"?

A: "Collaboration area" is just a broader way to describe all of the subgroups in CDI that have formed around member interests. The groups have a wide range of goals and meeting styles, so we are refraining from calling them all "working groups." However, if you are used to thinking of all of the CDI subgroups as working groups, this is essentially what collaboration areas are.

The September 13, 2017 CDI monthly meeting happened in the wake of major hurricanes and earthquakes, and in the midst of a severe wildfire season in the western U.S. We heard from USGS speakers that lead efforts and applications that work with hazards data.

Subduction zones! Earthquakes, tsunamis, landslides, and volcanic eruptions

Joan Gomberg presented on the USGS plan to reduce risk where tectonic plates collide, and posed the question of how her group could engage with the CDI. (See the USGS circular.) We are now exploring the best way to help facilitate their group in the CDI Earth Science Themes Working Group

Wildfires!

Elizabeth Lile and Jodi Riegle gave an overview of the GeoMAC wildfire application, a multi-agency project that displays near real-time information on fire perimeters.

Hurricanes and floods!

Blake Draper demoed the USGS Flood Event Viewer which allows users in the public to access flood data associated with events like specific hurricanes.

 

In the opening Scientist’s Challenge, we brought up the topic of getting started with reproducible notebooks and R Shiny apps, two tools that are helping to improve the way processes are documented and visualizations are shared! We welcome suggestions on specific topics about these tools - make a note on our forum or send an email to cdi@usgs.gov.

In our interactive segment, we heard from the audience about our preferred learning style for new tools - there wasn’t an overwhelming winner, but most respondents preferred to learn in a group then work alone, a close second was the group that preferred hands-on sessions with experts, followed by a smaller group that prefers to learn it themselves. We’ll try to have a variety of methods when offering training resources. It’s always great to hear from the community!



Check out more details, including slides, on the September Monthly Meeting wiki page

The joint CDI Tech Stack / ESIP Tech Dive group held a special bonus session on 8/31/17 that showcased ERDDAP examples. (See their August 10th webinar for an introduction to ERDDAP: Easier access to scientific data.)

Speakers included: Jenn Sevadjian, Jim Potemra, Conor Delaney, Kevin O'Brien, John Kerfoot, Stephanie Petillo, Charles Carleton, Eli Hunter

One example: ERDDAP makes it possible for oyster farmers to view data dashboards of real-time environmental conditions that may affect their crop.

On Sept 5, 2017 the Metadata Reviewers Community of Practice worked on improving some of the data management resources that the USGS shares on its Data Management website, including the Data Review Checklist and the Metadata Review Checklist.

The user needs when checking proper encoding of xml metadata records are not documented now, so Fran Lightsom will be leading a use case process to clarify those needs. Contact Fran if you are interested in participating in the use case process, flightsom@usgs.gov.

See the recommended revisions and more detail on their meeting notes page.

See the current information for reviews of data and metadata on the Data Management Website Data Release Page.

On August 15, the Bioinformatics Community of Practice hosted a presentation on KBase, a large-scale bioinformatics system that enables bench biologists and bioinformaticists to upload their own data, analyze it alongside collaborator and public data, build increasingly realistic models, and share their workflows and conclusions.

Ben Allen from Oak Ridge National Laboratories gave an overview and demo.

View the recording and slides on the meeting page.

At the August 9, 2017 Monthly Meeting, we heard about several topics that help when designing apps, software, and websites to communicate about our work, including information architecture, software development, and user experience. See the recording and slides at the meeting page.

News about the CDI Request for Proposals

Kevin Gallagher opened with thanking everyone the ideas for integrated science that came in since his call for ideas at the July CDI meeting. He also let us know that the CDI Request for Proposals is going to be different this year, in light of the USGS Executive Leadership Team’s ongoing discussions about Integrated Predictive Science Capacity. We won’t have the same process or timeline as the past few years with the CDI RFP Guidance going out in September. The ELT is focusing in on some topics and projects that will influence the RFP process - we’ll let you know more as soon as we have more information.

Do you need Information Architecture?

I gave a brief review of some of the Information Architecture (IA) topics we’ve been touching on recently, including not just the organization and design of websites or apps, but also factoring in user experience, usability, and information design. I recommended the site abbytheia.com for lots of IA tips. Asking the audience members if they managed something that takes into account design, usability, or information architecture, it turned out that 70% of us manage a web application or tool that takes this into account!

New CDI Software Development Cluster

Blake Draper introduced the CDI Software Development Cluster to help spread knowledge among software developers. (A cluster is an informal working group in CDI, borrowing from the ESIP terminology.) To join, email cdi@usgs.gov and we’ll get you on the list. Check out their wiki page to learn more.

Software Metadata introduction and best practices

Eric Martinez introduced a proposal for a simple, standardized way of documenting software so it can be easier to discover, and therefore easier to re-use existing solutions. He presented the metadata recommended by code.gov, a government platform facilitating code discovery and re-use.

The best practice is to create a code.json file for each software project.

See an Example: https://usgs.github.io/best-practices/code.json

A few other resources:

User experience lessons

Rachel Volentine from the User-eXperience Lab at the University of Tennessee, Knoxville, gave an overview of activities, equipment, and lessons learned from her lab. She showed some results and findings from the DataONE search interface testing and the USGS Science Data Catalog. Some of her UX Lessons Learned is “We are not the user” so we must develop trust, work with users’ existing habits, and don’t make the user think too much!

You can see more about the lab at http://cics.cci.utk.edu/user-experience-lab

Future monthly meetings

Finally, we ended with another poll: “What kind of content would you like to see more of in CDI Monthly Meetings? (choose up to two). So yes, it was mentioned that the choices were not completely exclusive of each other, but in any case we ended up with a three way tie, meaning we will be continuing to see a variety of different formats in our monthly meetings.


See you at the next monthly meeting on September 13, 2017!

On August 10, 2017, as on each second Thursday of the month, CDI has a double-header with the Semantic Web Working Group and Tech Stack Working Group calls.

Mapping the CDI with SWWG

In the Semantic Web Working Group (SWWG) call, Madison and I brainstormed with the SWWG team on a conceptual model for a CDI Knowledge Base. Such a knowledge base would help us to visualize and query for connections between groups, projects, people, and other resources made available by the CDI.

Using the CMap tool, we had a fun conversation, led by Alan Allwardt and Dave Govoni, about a draft map and how we might take the next steps in using such a map. If you have ideas about such a map, don't hesitate to join in the conversation, you can email cdi@usgs.gov to reach us and learn more.

More notes are available on the SWWG meetings page.

Results of brainstorming so far. DRAFT!

Easier access to scientific data with ERDDAP - Tech Stack WG

On the Tech Stack call, Bob Simons, an IT specialist with NOAA’s Environmental Research Division, presented on ERDDAP.  ERDDAP is a data server that gives you a simple, consistent way to download subsets of scientific datasets in common file formats and make graphs and maps.

View the recording on YouTube.

ERDDAP was developed to address challenges in finding and downloading data to your favorite client software.

ERDDAP works with gridded and tabular data.



There are many different installations of ERDDAP, here is one with oceanographic data (e.g. data from satellites and buoys) and more information: https://coastwatch.pfeg.noaa.gov/erddap/index.html


Fun fact: "ERDDAP" used to be an acronym (Environmental Research Division Data Access Program), but it outgrew that original description. Now, please just think of it as a name, not an acronym. (from the ERDDAP > Information page)

The Metadata Reviewers Community of Practice had a presentation from Lisa Zolly about Metadata Tips for Better Discoverability of Data in the USGS Science Data Catalog on August 7, 2017.

The slides are available on the meetings page.

Some highlights:

  • Using USGS keywords for metadata is very critical to achieving browsability to your data!

  • The USGS keywords, from the USGS Thesaurus, are not meant to be discipline specific, they are like an index to the corporate holdings. You can always use another vocabulary to add other, more specific keywords to your data.

  • When you are filling out metadata, putting the dataset DOI in the <onlink> field will properly access it from the “Get Data” link.

It's important to have keywords that serve both coarse-level data browsers and more granular-level advanced users.

Also useful: 

Thanks, Lisa, for the tips on achieving better discoverability of data, and the mechanics behind it.

The next meeting of the Metadata Reviewers CoP will be on Tuesday, Sept 5 - note the new date to avoid Labor Day.

CDI's virtual meeting on July 12, 2017 drew a big crowd to learn about uses of augmented and virtual reality in the Earth Sciences. View the recording and slides on the July meeting page.

Continuing the discussion of Integrated Science

In his introductory remarks, Kevin Gallagher urged the community to continue discussing integrated science pilot projects that will speak to the USGS FY18 Bureau Priority of building an integrated predictive science capacity. We were encouraged to suggest projects we would like to augment, projects we would like to share with the community, and projects we want to learn more about, at http://bit.ly/2v5niZf or by email to cdi@usgs.gov.

Use data, not opinion!

In the Scientist’s Challenge segment, Jordan Read and Lindsay Carr presented on Data-driven web design with A/B testing and experimentation.  They started the discussion about obtaining quantitative information for improving science communication through our websites and apps. "Use data, not opinion!"


Augmented reality at the USGS

Pete Cinotto from the USGS Indiana-Kentucky Water Science Center demonstrated uses of augmented reality at the Indiana-Kentucky Water Science Center, including to communicate stream gage information, and to demonstrate contour lines and water flow in a cool augmented reality sandbox. Augmented reality adds information to the surrounding world (locations, images, objects, etc.) as opposed to virtual reality, which creates a new reality.

 

Opportunities for virtual reality from drone-captured terrain

David Krum and Ryan Spicer from the University of Southern California Institute for Creative Technologies spoke about Drone Based Terrain Capture and Virtual Reality and the potential for collaborating with them on projects that are using virtual reality to explore terrain elevation and related characteristics like line of sight and slope. They can be contacted at krum@ict.usc.edu and spicer@ict.usc.edu.
