Heritage Conservation Map

Archival research by the Institute of Art History of the Czech Academy of Sciences on an interactive map.

Project name

Heritage Conservation Map

People, associations and cases of Czech heritage conservation from 1900 to 1960 on one map. It shows who worked where and how people, institutions and cases were connected.

Description

Challenge: In a NAKI research grant, the Institute of Art History of the Czech Academy of Sciences studies how heritage conservation worked in the first half of the 20th century: who made the decisions, which institutions were involved and what the cases were about. It wanted to show the results of its archival research to both the public and experts in a better way than tables - on a map and over time.

Solution: Together with the research team we designed the data model (person / institution / case, the links between them and years of activity) and built a public map application. Points are filtered by search and on a timeline - by year or by four historical periods. Clicking a point opens a side panel with a profile and shows all related points on the map, connected by lines. Every point has its own URL, so the project website and publications can link to it directly.

Result: The map is publicly available as part of the project website. Data grows with the research, and we have been developing the map since 2023.

Data & tech

  • Data: people, institutions and cases from archival research, WGS 84 coordinates, years of activity and the links between them.
  • Time: a year-by-year timeline and four periods (1900-1918, 1919-1937, 1938-1945, 1946-1960).
  • Map: Leaflet with marker clustering on OpenStreetMap, details in a side panel instead of pop-ups.
  • Links: every point has its own URL, browser history works.
  • Data feed: a PHP service returns GeoJSON.
