19th Conference Digital Approaches to Cartographic Heritage (ICA DACH) in Prague, Czech Republic, 17-19 September 2025

[Геннадий Воля]

Invitation

The Commission on Cartographic Heritage into the Digital of the International Cartographic Association, continuing the tradition of its annual Cartoheritage Conferences, since 2006, is organising the 19th Conference Digital Approaches to Cartographic Heritage (ICA DACH) in Prague, Czech Republic, 17-19 September 2025, in partnership with the Charles University, Faculty of Science and the Aristotle University of Thessaloniki, CartoGeoLab - Laboratory of Cartography and Geographical Analysis. The conference is under the patronage of The Czech Cartographic Society and it is supported by the MAGIC - Map & Geoinformation Curators Group and the Aristotle University of Thessaloniki Research Committee.

The Programme will be organised in thematic sessions dedicated to issues relevant to the subjects usually treated in the Conferences of the ICA Cartoheritage Commission, according to its Terms of Reference (2023-2027).

Possible topics include but are not limited to:

• Digitisation - Georeference.
• Content analysis in terms of geometry and thematics of cartodiversity*.
• Landscape change studies based on map-archival sources.
• Visualisation of Cartoheritage, including thematic portals.
• Interconnection of cartographic archival sources, especially map and textual data.
• Historical terrestrial and aerial photography, including photo-related post-cards and relevant material - cartographic parametrisation.
• Cartoheritage web providing issues.
• Interaction of cartoheritage with map and geoinformation curatorship of cartodiversity.
• Development of cartoheritage as a cultural issue, within the context of GLAM**, addressed to education and to the general public.
• Geographic affinities with Cartoheritage.
• Cartoheritage and Digital Humanities.
• Other relevant issues of the Cartoheritage ecosystem.

*Cartodiversity: manuscript and printed maps -loose and/or bound-, books with maps, map atlases, globes and related cartographic representations in 2D and 3D, depicted in a variety of supporting material like e.g. parchment, paper, wood or other writable/engravable media.
**GLAM: the acronym for Galleries, Libraries, Archives, Museums.

The presented papers are published in the Conference Proceedings (ISSN-2459-3893) available in digital form during the Conference.

The Conference is kindly hosted by the Charles University, Faculty of Science.

The Conference Board is advising and implementing the overall organisation.

Claudius Ptolemy’s Geography

• 6,300+ ancient locations with coordinates (cities, citadels, altars, temples, harbors, mountains, capes, bays, lakes, markets, forests, marshes, river sources, bends, confluences, mouths, etc.)

• Ancient coordinates unusable in modern GIS without prior georeferencing

Objectives

• Estimate modern coordinates for every location described in Ptolemy’s Iran, Afghanistan, Turkmenistan, and Balochistan

• Develop modern GIS assets for that set of locations using ArcGIS Pro and Google Earth

• Improve our understanding of how human civilization progressed in the region of interest and of how much the ancient geographers knew about it

 

Conclusions

• We have presented a new digital reconstruction of Ptolemy’s map of 14 ancient provinces that comprise the modern Iran, Afghanistan, Turkmenistan, and Balochistan

• This achievement closes the gap between our earlier reconstructions of Arabia and the Fertile Crescent in the west and India in the east

• The results were obtained thanks to a modified methodology leveraging our prior reconstruction of al-Biruni’s map from The Masʿud Canon

 

Future Work

• Extend the study to more regions in Ptolemy’s Geography

• We are planning our next digital reconstruction to be an improved version of Ptolemy’s India and Taprobane.

• Place the tribes listed by Ptolemy

• Improve deliverables:

• Better GIS assets (e.g., more feature-rich KML files, ArcGIS filesets, etc...)

• Translations and internationalization work • Website (http://www.claudiusptolemy.org/ ) and feedback mechanisms

• Develop an online digital atlas and database of Ptolemy’s Geography including modern coordinates of objects
