Meeting Notes

May 11, 2020

Don Sweetkind, USGS presented 3D issues related to the new NGMDB Phase 3 initiative, such as efforts to inventory 3D geologic models within the USGS and efforts to create National-scale (contiguous US) subsurface horizons, as well as some of his work as examples.

CDEFG Session 1 about 3D mapping and databases. Mark Yacucci from the Illinois State Geological Survey demo'd one of their 3D models and how they morph it to their online cross section viewer http://maps.isgs.illinois.edu/vxs4/mchenry/; https://prairie-research.maps.arcgis.com/apps/MapJournal/index.html?appid=f270312c61634098a6a1a55c86322f56. Mike Hendricks discussed how the Alaska Division of Geological & Geophysical Surveys has added layer information to the GeMS schema for geologic polygons, and potentially for faults and contacts, to model stacked units.

Dave Soller described the new push for the National Geologic Map Database's Phase 3 and possible funding opportunities to help the effort. Please contact Dave at drsoller@usgs.gov if you have ideas about how your state could contribute.

At this meeting, DGGS gave a brief update presentation of recent GeMS database work, and we discussed a few tools for diagramming geodatabases in Esri products. We also went “round robin” around the various attendees and folks described where they are in GeMS implementation, current projects, and related needs and concerns.

January 13, 2020

Folks implementing GeMS posed questions about the best way to create a Glossary with minimal effort. Some states are interested in creating a Glossary resource that we can all pull from. Jen Athey volunteered to compile GeMS Glossaries and make the definitions available. Please feel free to send what you have so far to jennifer.athey@alaska.gov to be added to this resource.

December 9, 2019

Discussion topic was where to put different kinds of geologic information in GeMS. We really just scratched the surface of this topic. Trish Ekberg from Alaska DGGS gave a presentation on how DGGS has tweaked the schema, which we feel still honors the ideals of data organization in GeMS. Then we walked through some examples of where to put different kinds of data in the schema. There was a fair amount of consensus.

GeMS stakeholders would like to see an increase in communication in the geologic community to help with issues and questions as GeMS gets implemented. Since this meeting, some new tools were implemented. Following is from an email to the DMT listserv from Evan Thoms, USGS:

For those working with GeMS data in ArcGIS, I wanted to make sure you all knew that there are now two versions, one for ArcMap and one for ArcGIS Pro. They are available from GitHub:

The two versions have been developed separately because ArcMap uses Python 2.7.x and ArcGIS Pro uses Python 3.x and there are syntax and arcpy differences between the two. For instance, note that with ArcGIS Pro, ESRI has not (yet!) ported over the entire Metadata toolset of geoprocessing tools. If you want to use the Purge Metadata or FGDC CSDGM2 Metadata tools from the GeMS toolbox, you will have to do that in ArcMap.

As before, downloading the tools does not require a GitHub account, but if you want to create an issue there to report a bug or request an enhancement or new feature, you will have to log in.

Now linked from both repositories (look for the badge that says 'chat on gitter' below the title in the readme section) is a newly created Gitter room at https://gitter.im/gems-schema/community. Gitter is a free and open-source chat platform for developers and users of GitHub and GitLab repositories. Go there for non-code specific questions about the use of tools in either toolbox as well as questions about working with the GeMS schema in general. Feel free to post news about workflow documentation, the publication of GeMS databases, or other resources that your group has available if you think they could be useful to the community. Log in to Gitter using a GitHub, GitLab, or Twitter account.

Finally, as always, you are invited to collaborate on the development of the tools. See the suggestions in the readme section of either repository.

Thank you! Evan
