The digitization of the 1938 map, combining the work completed during the 2023 and 2024 fiscal years, has now been finalized. We are planning to make this data available in a more user-friendly format in the near future.
For the 1900s map, we will continue expanding and enhancing the dataset moving forward.
In addition, we are also working on annotation tasks for the automatic detection of architectural elements. The results of this work are scheduled to be released as a new feature of the database in the near future.
