Overview# This time, we try georeferencing using Allmaps.
https://allmaps.org/
Allmaps is described as follows.
Allmaps makes it easier and more inspiring to curate, georeference and explore collections of digitized maps.
This time, we use the “Bird’s-eye View of the University of Tokyo Main Campus and Faculty of Agriculture Buildings” held by the University of Tokyo Library for Agriculture and Life Sciences.

Method# Access the following.
https://editor.allmaps.org/#/
This time, since we use the second image, enter the following URL in the form.
https://iiif.dl.itc.u-tokyo.ac.jp/iiif/agriculture_re/nou_tatemonochokanzu/0002.tif
On the following page, press the “Georeference” button.
You will navigate to a page where the image and map are displayed side by side. Point corresponding locations on the image and map.
Then, press the “Results” button and click the “View current image” link.
As a result, you navigate to a viewer page like the following.
Created Data# On the Editor screen, you can copy or download the created JSON data. The following JSON data was created.
