Project
The overall objective of the project is to develop an original, web-based, scalable and modular system ("Geo-harmonizer") for hosting and accessing various thematic geospatial data layers (vector and raster GIS layers) to support cross-border services over the entire continental Europe. The team will create a data portal and a software suite extending a wide variety of free and open-source software solutions for geospatial data (FOSS4G) in combination with state-of-the-art Machine Learning algorithms, and will be made available within EU-supported High Performance Computing (HPC)/Cloud computing infrastructures. The functionality of the system will be demonstrated vis-à-vis a list of new, added-value, pan-EU data sets (seamless continental Europe cover time-series (2000-2020), environmental quality indicators and other products)
