US Interagency Elevation Inventory

Dear colleagues,

The USGS National Geospatial Program is again updating the US Interagency Elevation Inventory. We invite you to provide us information so that your data is discoverable by others. Your data need not be in the public domain, and the entry will provide a link to inquire about the data, or to a download site if available. This is not a repository for data; it is a way to make data findable. If you have high quality lidar data you wish to donate to USGS data repositories, we can have the conversation at any time.

https://www.coast.noaa.gov/inventory/

If you wish to make your data discoverable through the inventory, we will need the following:
  • Shapefile footprint with metadata
  • Vendor tasking, if available
  • Status (in work, available, etc.)
  • Restrictions (if it is public domain)
  • QA or acceptance reports (so we can calculate quality level)
  • Contact information (for internal purposes only; no PII will be publicly posted)
  • url for download or public inquiry (if available)
Due dates are as follows:
  • Arizona (to Drew by COB 3/25/2019)
  • Nevada (to Carol by COB 3/11/2019)
  • Hawaii (to Drew or Carol by COB 3/25/2019)
  • Pacific Basin Islands (to Drew by COB 3/25/2019
  • California (to Drew or Carol by COB 3/25/2019)

If you have an awareness of data that you did not procure, we are happy to chase down the source if you can provide a pointer to a contact person. We try to duplicate what currently shows in both NOAA’s digital coast and Opentopography.org. If you have updates to an existing entry on the inventory, please let us know by the due dates above.

Any questions, please call either one of us, and feel free to pass this request along to others inside or outside of your organization so that our inventory can be as up-to-date as possible.

Sincerely,

Carol and Drew

Geospatial Historian

The Geospatial Historian is “a tutorial-based open access textbook for historical scholars and digital humanists designed to teach practical digital mapping and GIS skills that are immediately useful to real research needs.” Under Lessons, you will find two series of GIS tutorials geared towards historical analysis and applications. The first series, which uses open-source software, is comprised of four lessons that the project team created for the Programming Historian. The second series contains five lessons that teach mapping, georeferencing, and other applications using ArcGIS. The site also offers a helpful list of resources for Finding Spatial Data, organized by data type and featuring data from around the world. Check it out!

OpenTopography

OpenTopography provides high-quality geographic data relating to earth science as well as a platform for researchers to share their own data. Based at the University of California, San Diego, OpenTopography is an ambitious project that “facilitates community access to high-resolution, Earth science-oriented, topography data, and related tools and resources,” and is funded through the National Science Foundation.

You can search or browse the project’s datasets via an interactive data map and a data catalog, both found under Data. Most of these datasets are available in Lidar point cloud format, and many are also available in other formats, such as raster or Google Earth.  Check it out!

California Releases Interactive Public Geoportal

California has adopted a massive, interactive online database of location-based government data that includes over 1200 publicly available data sets from 25 state entities.

The California State Geoportal collects geospatial data from government agencies including housing, water, transportation and health information. The data is compatible with geolocation software and is designed to be shared, layered onto maps and analyzed.

The portal was designed by ESRI.  Check it out!
