Palestine Open Maps

Palestine Open Maps is a platform that seeks to combine emerging technologies for mapping and immersive storytelling to:

  • Open-source and make searchable, for the first time, a uniquely detailed set of historic maps from the period of the British Mandate of Palestine;
  • Curate layered visual stories that bring to life absent and hidden geographies, in collaboration with data journalists, academic researchers, and civil society groups.

This alpha version of the platform allows users to navigate and search the historic map sheets, and to view basic data about present and erased localities.
