- OpenHistoryMap aims to create a toolchain and tools for teaching history using modern web-GIS tools. It allows representation of historical data with varying levels of detail, sources, and time periods. - The software uses open source tools like Python, PostGIS, and Docker. Data is stored in Postgres and rendered on a tileserver for viewing maps on openhistorymap.org. - Tools are being developed for tasks like digitizing old maps, reconciling data from different sources, and creating visualizations for educators. Future goals include integrating with Wikipedia and adding time series and 3D modeling capabilities.
