Monitoring Changes in the Condition of the Interior of Cultural Heritige Objects Using Remote-Sensing Data

Orthodox churches and their paintings are an important part of the historical heritage. Along with well-preserved and maintained churches, there are a large number of dilapidated buildings included in the list of cultural heritage sites, which are in a deplorable state due to lack of funds for restoration. The expanding possibilities of collecting diverse information on cultural heritage make it possible to accumulate and systematize information about sites in order to be able to document their reconstruction and restoration in the future. This study addresses the problem of analyzing changes in the wall paintings of Orthodox churches based on remote-sensing data using multi-temporal interior images, including amateur photography.
