A map showing volunteer contributions from the inception of TNMCorps through March 31, 2022. Contributions are displayed by fiscal year with contributions during the current fiscal year displayed by quarter. Points are color-coded on a graduated gray-to-red scale; older points are gray and newer points are red.  

A map showing all the standard edited points as of May 2, 2022. These points need to be Peer Reviewed or checked by an Advanced Editor. They have a green border in the editor.

A map showing all the finished points as of May 2, 2022. These points do not need to be checked again at this time. They have a blue, purple, or yellow border in the editor.

A map showing all the remaining unedited points as of May 2, 2022. These points need to be checked by a Standard Editor or an Advanced Editor. They have a red border in the editor.

Karymsky volcano, one of the most active volcanoes of Kamchatka's eastern volcanic zone, erupted on April 20, 2022. This pan-sharpened Landsat 8 image captured the event. Overlaying the infrared data over the natural color image highlights the heat signature of the active flows.

The largest coral reef ecosystem in the world, the Great Barrier Reef (GBR), is threatened by many human-made impacts. Due to the size of the GBR and limited accessibility, mapping and monitoring has always been a challenging task. Remote Sensing is an effective technique that provides valuable information for the GBR ecosystem.

The boreal forest biome is projected to shift northward due to continued climate change over the coming century. Researchers evaluated early indicators of a boreal forest biome shift using four decades of Landsat observation datasets.

A map showing all the edited law enforcement points with no edit history. Points with no edit history are concentrated in Pennsylvania, Virginia, West Virginia, Kentucky, Tennessee, and North Carolina, all of which are states that participated in some of TNMCorps’ earliest mapping challenges from 2014 and 2015.

A map showing all the edited prison / correctional facility points with no edit history. Prisons are another feature that was targeted by earlier challenges, so points are concentrated in these earlier challenge states (i.e., Virginia, West Virginia, Kentucky, Tennessee, and North Carolina).

A map showing all the edited hospital / medical center points with no edit history. Like prisons, hospitals don’t change as much as some of the other feature types. Perhaps the most frequent change these points will see is in naming conventions.

A map showing all the edited ambulance service points with no edit history. Ambulance and EMS stations frequently close, open, or move so this is an important feature to reverify.

A map showing all the edited cemetery points with no edit history. Cemeteries are much less likely to change as some of the other feature types, therefore, we’re asking standard editors to focus on other points with no edit history before cemeteries. For our peer reviewers and advanced editors, we ask that you check the edited (green) points.  

A map showing all the edited post offices with no edit history. Post offices may see moderate change as facilities relocate to handle additional capacity and in response to USPS restructuring, fluctuating populations, etc.  

A map showing all the edited schools with no edit history. Many points are clustered around major cities. Schools can be prone to frequent changes, so it’s especially important that these points are researched and reverified.

A screenshot of a cemetery in the review queue. This point was flagged for the review queue because it is in proximity to another point with the same symbol.
