APPROACH has emerged from a multi-sector cooperation containing heritage, architectural and cultural organisations, municipality with architectural and media enterprises and a VET institution with media classes. The partners involved are summarised in section 2.1. The main objective of this transnational consortium is to assemble an online learning platform as an open educational resource, targeting firstly architectural, art historian and urban analyst students and, in parallel, media and web designer students in VET and on other levels. The main output of the programme is a 4-piece collection of interactive 3D city maps showing the centres of Edinburgh, Granada, Budapest and Lublin as non-formal educational tools. The creation of the animated models is based on a scientifically carried-out historical and urbanistic research collecting all available source materials, like old maps and archive texts to be able to rebuild and represent the selected time periods of the cities - from their foundation to modern times. This approach gives the possibility to freely explore the urban environment in both space and time, collecting knowledge about the monuments and urban textile through interaction with the models. Moreover, each “time map” marks significant periods of social and political changes, which drove architectural and spatial changes. Our aspiration is to provide APPROACH users with an opportunity to compare how and where each city evolved in different historic phases. We are proud that the APPROACH online platform is a free of charge, intuitive, and accessible. The development of the “time maps” was managed by a comprehensive methodology that involved historic research, transformation of raw data to 3D models, ongoing verification of outputs, and the compilation of a learning narrative. The project was delivered by four groups: researchers, modellers, project managers/coordinators, and students. Each modelled city had its research team collecting historic information, turning them into visual templates that would then be passed onto modelling teams based in Budapest and Cluj. In the next stage the modellers created 3D “white models”; their accuracy was verified by the researchers before the entire model received textures and was turned into the “interactive content”, which involved a fair amount IT engineering. A vast amount of historic information was collected throughout the process. The research teams used a wide range of sources including: maps, drawings, paintings, photos, and texts. “Info-boxes” provide narrative to the models, containing the most relevant learning information. They redirect to external sources for those seeking more detail. Some of the most interesting research discoveries can be found in this comprehensive study, which binds together all outputs of the project, summarising the steps of the product-oriented co-operation with the architectural and media enterprises. Its main purpose is to promote the project ideas among VET institutions and relevant stakeholders and in this way to contribute to the creation of further educational material similar to the products of this project. To help the same initiative, a series of video tutorials and text descriptions was also produced to teach the creation of 3D interactive contents. The production of this online material is connected with a training programme, in which blended mobility of VET students took place combining virtual involvement with short-term physical mobilities. As a part of the training, the media and web designer students were involved in learning, testing and therefore the creation of the final resource. The chapters of the material are to teach useful techniques and methods about 3D modelling, composing animations and programming interactive functions in co-operation with for-profit firms. In this way the training leads to the recognition of the latest trends of CAD, BIM and game development technologies, providing knowledge and competencies with remarkable labour market relevance. With different techniques and target groups, all the outputs of the project provide working models and pathways for the easily intelligible visualisation of urban environment and monuments as well as for the integration of digital competences to the development of further educational resources.Following a series of public meetings in all partner cities we have confidence in the educational value of the project’s outputs and their future potential for development. It is important to stress that the project involved design students from the Riga School of Art who actively participated in the project delivery and engaged with professional modellers and researchers. The educational aspect of the project is also represented by a series of online modelling tutorials, which can be found on our beautiful website.
