preservenice: preserving venetian material culture
DESCRIPTION
The PreserVenice initiative is dedicated to obtaining, funding, providing documentation, and increasing awareness of material culture to contribute toward preservation. We created interactive maps, designed a mobile application, updated PreserVenice's website, and conducted an analysis of different measuring techniques for boats in order to provide the means for future restoration and preservation.TRANSCRIPT
