Thanks Dan and congratulations to the originators -
'This project was initiated at Impact Data Lab, a workshop organized by Visualizing Palestine and Columbia University Studio-X Amman in March 2018. The app is under continuing development by Visualizing Palestine with support from a number of other individuals.
Development team: Ahmad Barclay, Majd Al-shihabi (supported by the Creative Commons Bassel Khartabil Free Culture Fellowship), Hanan Yazigi, Morad Taleeb, Henry Zaccak and Bassam Barham.
Special thanks: Stella Ioannidou, Noor Lozi, and to Nora Akawi and the Columbia Studio-X Amman team.
The project would also not have been possible without data gathered and digitized over many years by Salman Abu Sitta (Palestine Land Society), Palestine Remembered, Zochrot, and other individuals and organizations.
The map sheets themselves were produced by the Survey of Palestine—a British Mandate institution—and the Palestine Exploration Fund, and were drawn from sources including the National Library of Israel, the National Library of Australia, the David Rumsey Map Collection. All of the maps are considered public domain under the UK Copyright, Designs and Patent Act 1998, and were marked as such on the source websites.' https://palopenmaps.org/about
