In August 1908, a white mob attacked Springfield, Illinois’s Black community, destroying homes and businesses and lynching two Black men. National outrage over the violence helped spur the movement that created the NAACP the following year.

OpenDroneMap is an open source photogrammetry toolkit to process aerial imagery (usually from a drone) into maps and 3D models.[3][4][5] The command-line interface is hosted and distributed freely on GitHub, while the graphical user interface requires a purchase.[6][7]
OpenDroneMap has been integrated within American Red Cross's in-field Portable OpenStreetMap system.[8]
As of 2026, OpenDroneMap is a separate project from WebODM.[9][10]
OpenDroneMap can be controlled either from a command-line interface or through a web interface (OpenDroneMap Desktop). It is recommended to run OpenDroneMap using Docker.[11]
OpenDroneMap uses OpenSfM and other libraries to perform the specific tasks in its workflow. Before processing the images, it can lower their resolution in order to save computational resources. OpenDroneMap uses the OpenSfM library to detect and match features, create tracks and determine their 3D positions along with the positions of the cameras. Then it uses the OpenMVS library to generate a dense point cloud from which it generates meshes. After that, the Geospatial Data Abstraction Library and the Point Data Abstraction Library are used for orthomosaic generation and georeferencing.[4]
OpenDroneMap can also process aerial videos by cutting them into still images.[11]
OpenDroneMap supports parallel computing and can utilize GPUs. It has a split-merge feature, which significantly reduces the performance, but allows computers with small amount of RAM to process large datasets. The official recommendation is to use 128 GB of memory to process 2500 images.
It was determined that the optimal number of CPU cores for large datasets is 20, and there is little to no performance gain beyond 20 cores.[11]

OpenStreetMap (OSM) is a map database maintained by a community of volunteers via open collaboration. Contributors collect data from surveys, trace from aerial photo imagery or satellite imagery, and import from other freely licensed geodata sources. OpenStreetMap is freely licensed under the Open Database License and is commonly used to make electronic maps, inform turn-by-turn navigation, and assist in humanitarian aid and data visualisation. OpenStreetMap uses its own data model to store geographical features which can then be exported into other GIS file formats. The OpenStreetMap website itself is an online map, geodata search engine, and editor. OpenStreetMap was created by Steve Coast in response to the Ordnance Survey, the United Kingdom's national mapping agency, failing to release its data to the public under free licences in 2004. Initially, maps in OSM were created only via GPS traces, but it was quickly populated by importing public domain geographical data such as the U.S. TIGER and by tracing imagery as permitted by source. OpenStreetMap's adoption was accelerated by the development of supporting software and applications and Google Maps' 2012 introduction of pricing. The database is hosted by the OpenStreetMap Foundation, a non-profit organisation registered in England and Wales, and is funded mostly via donations.
Stephen Coast (born 20 December 1980) is a British entrepreneur and the founder of the OpenStreetMap community-based world mapping project and CloudMade, a geography-related company.
Sakay.ph is a Philippine web mapping service and mobile app that provides public transport route planning and navigation within Metro Manila and its surrounding areas. The platform uses a combination of official government transport data and crowdsourced route information to provide directions for various modes of public transport in the Philippines, including jeepneys, buses, rail systems, and ferries.
Before the 1921 destruction of Tulsa’s Greenwood District, Black residents had created a remarkable center of business and community life. The district included stores, professional offices, entertainment venues and homes owned by Black citizens. Understanding Greenwood means learning what was built—not only what was burned.
