WG 5: Visualisation of CH objects and its dissemination
Leader: Dr. Selma Rizvić (BA), vice-leader: Dr. Despoina Tsiafaki (HE)
1st WG task st5.1 Identification, planning, implementation and testing of typical applications of visualisation within CH domains CH objects can be visualised in many different waysand for different purposes. Applications range from edutainment and relatively simple presentation to the general public to accurate 3D records surveyed for specialist professional research and conservation. Each purpose bears on the quality expected from visualisation. Characteristics of the data have to be identified and the visualisation processes structured and implemented accordingly.
2nd WG task st5.2 Further development of visualization techniques
Development of innovative visualisation techniques including integration of multi-sensor data as base for enhanced exploitation of information pertaining to shape and colour, as well as other object data and metadata.
St. Etienne meeting in March
WG5 meeting in St. Etenne.
At the WG5 meeting was discussed the first draft version of the outcomes report, case studies progress and next TF meetings. The report contains first classifications of CH visualisation applications and workflows.
Activities performed in 2014:
- Task force meeting in Xanthi in February 2014
- Joensuu meeting in April 2014
- Task force meeting in Sarajevo in June 2014
Results vs. Objectives
In all meetings various applications of visualization within CH domains were discussed and analyzed. It was concluded that there is a significant problem of terminology, as experts from different fields often refer to the same concept with different terms. Therefore an STSM has been initiated to research this question and propose common solutions.
There was a discussion about a possibility to compare existing projects which use data sets obtained by remote sensing methods. Following up this discussion, some case studies have been proposed.
After approval of case studies WG5 will focus its work upon them in the process of achieving the scientific tasks presented in the work plan of the project.
Taskforce meeting in Xanthi.
The following aspects have been set to be researched through STSMs:
- Definition of visualisation (e.g. as recording, documentation, dissemination)
- Evaluation of projects against standards
- Long-term preservation, management of CH visualisation projects
WG5 members have been active in preparation of proposals for Horizon 2020 calls.
WG5 members prepared several case studies proposals and submitted them to the COSCH call.
Following up the discussion on terminology, WG5 members undertook an informal brainstorming during the Joensuu meeting on the meaning of visualisation and documentation. Here are some propositions:
- it is not only to see but also to extract information and filter information and ask questions
- to experience the environment without actually being there and also to extract the information
- to give more information and show what is important for various experts
- registration of CH
- visualisation depends on a particular perspective
- visualisation aims to make CH approachable
- to visualize something that is not visible for any reason, because it no longer exists or is hardly accessible
- representation of everything we know and any possible source we can incorporate in visualisation
- representation of the object of the interest - it can be existing or non-existing object
- saving the cultural values, safeguarding them
- to record what is important
- to create and to keep historical record
- documentation is a basis for visualisation
- it is not just what we know of subject but also record of how this visualisation was achieved
- to have a record of all available information, including the methodology of documentation
This brief survey shows how different are perceptions of these terms coming from people of different backgrounds and expertise. It justifies our efforts in finding common definitions that will be used within the COSCHKR.
Objectives and tasks until the next meeting
The discussion between the participants resulted in determining the following elements regarding the work phases:
- plan the STSMs for the case studies,
- analysis of older 3D projects case studies and not only new ones,
- necessity to use open-source software in order to maintain accessibility and longevity of CH visualisation projects,
- collaborative STSMs could help explore the digitization and digital preservation of the CH objects.
The following future activities were identified:
- define the visualisation pipeline
- extend COSCHKR to cover more aspects than measurements
- identify possible misunderstandings in key terms of visualisation and documentation
- include the interactive virtual cultural heritage applications in COSCHKR application types
- discuss the cost of visualisation and its purpose in preparation stage
- submit the questionnaire for COSCHKR
