There is a gap between spatial synthesis and its tools and their successful deployment to the complex geographical studies. Advanced methods geocomputation can heal this gap. The objective of the project is to formulate new concepts of spatial synthesis based on advanced geocomputation methods, to develop procedures for their implementation in GIS products and to verify them by case studies and eye-tracking experiments. The nature of project relies on a number of significant advances in GIScience, mainly on (i) search, classification, prediction and modelling and (ii) visualization. The project builds its approaches on the nature of spatial thinking as a constructive combination of concepts of space, tools of representation, and processes of reasoning. There are six key project pillars of the project – Spatial synthesis concepts, Advanced geocomputation methods, Spatial synthesis support tool as a software component, Case studies and Eye-tracking experiment for evaluation of the spatial synthesis results.
