Confluence Retirement

Due to the feedback from stakeholders and our commitment to not adversely impact USGS science activities that Confluence supports, we are extending the migration deadline to January 2023.

In an effort to consolidate USGS hosted Wikis, myUSGS’ Confluence service is targeted for retirement. 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 myusgs@usgs.gov. Thank you for your prompt attention to this matter.

Thanks to Rich Signell and, most of all, Christoph Gohlke (who compiled the module so it will work with Arc 10). Rich and Curtis Price provided this example python script.
    • The image below shows an example of a raster that has been loaded into ArcMap from a remote dataset using the netCDF4 library and the OPeNDAP access protocol.
