Matt Baker (University of Maryland, Baltimore County) presented on 'Hyper'-resolution Geomorphic Hydrography: Methods, advantages, and shifting paradigm.

I always try to make myself look like I've been around for a long time with references to "do you remember when?" and I will do that now. I remember when the first LIDAR images started showing up at conferences and presenters would first show a standard (at the time) 30-meter DEM and then flip to the next slide that was LIDAR 1-meter resolution, and the whole audience would gasp in astonishment. Then this was followed by people saying "Well, none of the old tools work on LIDAR data, we have to build a whole bunch of new tools to analyze this higher resolution data." And that is what I thought of when watching these presentations. We've come a long way!

10/17 Risk CoP - Usability of volcano notifications

From the Risk Community of Practice meetings page:

We reviewed a few key announcements, including a preview to the FY20 Risk RFP Opportunity.

Following announcements, we heard from Carolyn Driedger, Hydrologist/PIO/Outreach Coordinator, Cascades Volcano Observatory and Tina Neal, HVO Scientist-in-Charge who discussed the process and results from a recent usability Study of the USGS Volcano HAzards Notification System (HANS). The Communications Work Group within the USGS Volcano Science Center began to write a 'Style Guide' for its HAzards Notification System (HANS) information products, which convey volcano status to the public and officials. As they wrote the style guide, they recognized the need for more formalized user input on which to base their guidance, both with formatting and wording. Carolyn shared some of the documents from this study and the group had a vibrant conversation about science communication following some questions she posed to everyone at the end of her talk. 

How should a daily update for volcano notifications be formatted for best readability and understanding?

October’s CDI meeting explored current practices on some technical aspects of delivering scientific data and results.  

DevOps' role in data integration and delivery 

David Hughes and Rob Djurasaj, from the CDI DevOps Community of Practice, presented on DevOps' role in data integration and delivery. In addition to an introduction to DevOps (the bringing together of software Development and Operations), they explained how certain new technologies are allowing the USGS NGTOC (National Geospatial Technical Operations Center) to improve their efficiency and save on costs. For example, efficiencies are gained by employing IaC, Infrastructure as Code, the process of managing and provisioning computer data centers through machine-readable definition files, rather than physical hardware configuration or interactive configuration tools. 

Advanced Amazon Web Services Cloud Development Kit Solutions at the National Geospatial Technical Operations Center. 

Packaging data and software: Jupyter as a publication platform 

Keith Maull and Matt Mayernik from the National Center for Atmospheric Research (NCAR) Library joined us to present on Packaging data and software. NCAR has been publishing reports since the 1960s, and increasingly both text and a code repository are part of the publication. How can they make the science in the publications reproducible for decades into the future? Some of their code can only run on supercomputers, and even tools like Jupyter notebooks sometimes do not fully run in new environments. They initiated discussion on optimal approaches for identifying, validating, characterizing, and preserving scientific information and tools. 

Reproducibility considerations related to user needs and computational environments.

9/10 Artificial Intelligence/Machine Learning - Deep neural networks for landscape conservation

Daryl Van Dyke, a spatial analyst for the Fish and Wildlife Service, presented on Utilizing Deep Neural Networks for Landscape Conservation: An Application of Google’s Tensorflow for a Cannabis Production Inventory in Northern California.

From the abstract: This presentation shows how an off-the-shelf Deep Neural Network (DNN) algorithm – Inception v2 – was retrained into a production classifier and applied to the problem of locating and sizing cannabis production on private lands in Trinity County. 

Daryl included a vision where anyone doing a GIS project in the Department of the Interior would be required to submit bounding rectangles on a 10-meter grid for every single feature they worked with. This illustrates how defining standardized products at the Enterprise level would be powerful for things like creating a training dataset for landscape level classification.

9/12 Tech Stack - Dealing with the volume and variety of Earth Science data

Michael Rilee, of Rilee Systems Technologies LLC presented about STARE (SpatioTemporal Adaptive Resolution Encoding for Scalable Integrative Analysis). 

From the abstract: Aligning and integrating different kinds of Earth Science data is a laborious process, leading most researchers to focus on more generic, high level data products that are more easily compared. Dealing with the great volume and variety of Earth Science data is the goal of the NASA/ACCESS-17 STARE project. STARE is a unifying indexing scheme addressing variety and is well suited for applying distributed storage and computing resources to address volume.

Roland Viger told us more about the National Hydrologic Geospatial Fabric: a framework for the integration of water information. NHGF is hydrologically informed information architecture for integrated science. Roland presented the concept as categorized by DNA, skeleton, and meat, which are related to hydroinformatics, information architecture, and high value data themes, respectively. The types of data and information involved include river corridor data, dynamic landscape characteristics, data models, data gathering, harmonization, and data integration.

River corridor information planned for the National Hydrologic Geospatial Fabric.

Being from a different USGS mission area and not having heard much about these before, the presentations were incredibly informative. Both of these projects are going to be integrating huge amounts of data and information, and I look forward to keeping up with their progress!  If you have suggestions for other USGS initiatives that you’d like to learn more about at CDI Monthly meetings, let us know at

8/5 Metadata Reviewers, Metadata review resources on the USGS Data Management website

Madison Langseth led a discussion about the proposed page on the Data Management Website about reviewing metadata. Details from the discussion can be seen on the group’s meeting notes page, and the Metadata Review webpage is now available and packed with useful information!

Creating a metadata record doesn’t end when the content is generated. Metadata review is an essential part of the process of creating a metadata record, and can involve finding a reviewer, checking technical and content aspects of the metadata, and communicating with the author. - from the USGS Data Management website

8/6 DevOps, Vector Tiles in National Park Service maps

Jim McAndrew from the NPS presented on National Park Service Vector Tiling activities. When web maps were first introduced, they relied on tiled raster data. But now vector data is used in the basemap itself instead of raster data. This allows web developers to access vector information in the basemap, and allows for custom on-the-fly styling. Jim discussed how the National Park Service made the switch to vector tiles, how they dealt with legacy applications, how they are making use of the newly available vector data, use in mobile apps, and future plans for combining information from other agencies in real time and displaying it in our web maps.

8/8 Tech Stack, The challenge of location

Matthew Purss from Geoscience Australia presented on The Challenge of Location and How Discrete Global Grid Systems can enable Spatial Data Integration.

Existing approaches and disconnected infrastructures coupled with the myriad of ways to describe and store location information limit our ability to discover, access and integrate spatial data across organisation and jurisdiction boundaries to produce reliable and actionable information. The Location Index project (LOC-I) aims to introduce a consistent way to access, analyse and use location data to support the effective integration of socio-economic, statistical and environmental data from multiple data providers to support the spatially enabled delivery of Government policies and initiatives.

Bridging the vector/raster divide to enable data integration.

Special Session: Stakeholder engagement panel & discussion 

Stakeholder engagement is an important piece of the USGS Risk Plan. But what does it mean to engage with stakeholders? What does co-production mean? What tools are used for engaging stakeholders and over what timelines during the course of a project? What types of challenges arise during stakeholder engagement? What are some of the surprising considerations to keep in mind while working with stakeholders? 

This special session was live from the Risk CoP meeting in Golden, CO and featured a panel discussion on stakeholder engagement. Panelists answered the following questions: 1) What does stakeholder engagement mean to you? What does co-production mean to you? 2) When, during the course of a project, do you engage your stakeholders? 3) Describe three tools you use for engaging stakeholders? 4) Can you give an example of a challenge you have faced in doing stakeholder engagement and how you overcame these challenges? (Paperwork Reduction Act, protected information, confidentiality issues) 5) What are some surprising considerations to keep in mind when doing stakeholder engagement? (e.g., inclusivity, ethics, manner of approach).

Software Development 6/27/19 - CDI Workshop Report Out

The Software Development Cluster welcomed new cluster co-lead Jeremy Newson, and reminded participants that the USGS Software Management Website is up and running at

At the June meeting, the cluster reviewed the many related sessions at the CDI workshop, including Software Release Q&A, the Software Development Cluster Breakout Session, a Software Release Practicum, and a Software Birds-of-a-Feather Lunch. Discussions in those sessions included considerations and ideas for cross-USGS collaboration, institutional support, and software developer career paths at the USGS

Some ideas and take-aways from the discussions include:

  • Should there be a “developer shop” or “center of excellence” where Science Centers could hire/ source Software Developers for projects?
  • Hiring of software developers at the USGS could be better coordinated to support career development.
  • An agency-specific tool to find people, skills, code reviewers, and existing software would improve collaboration.

Full notes can be found at the workshop Slides, Recordings, and Notes page (if you log in as a CDI member). Cassandra Ladino, Michelle Guy, and Jeremy Newson are the cluster leads.
