Core values

- **Historical and Educational Value**: The collection provides unparalleled access to historical maps, which are crucial for understanding historical changes, environmental shifts, and human activities over time. This is particularly important for educational and research purposes[1][4][5].
- **Technological Innovation**: The integration of historical cartography with GIS technology allows for the analysis and comparison of maps across different periods, which can inform contemporary issues such as climate change, land use, and settlement patterns[1][2][4].
- **Public Access and Democratization of Knowledge**: By digitizing and making over 135,000 maps available online for free, the project democratizes access to historical cartographic materials, benefiting a wide range of users including researchers, students, and the general public[4][5].
- **Preservation and Conservation**: The project ensures the preservation of rare and historically significant maps, safeguarding these resources for future generations and preventing them from being lost or degraded[2][4].
