Many national and global institutions share open data for anyone to use. One such institution is the European Space Agency (ESA) that shares the images from their satellites as open data. The ESA satellite data was utilized in Jamk University of Applied Sciences’ Data for Utilization project where the research investigated the use of Sentinel-1 synthetic aperture radar satellite images for storm damage detection. The research required an easy access to the satellite images over the whole research life cycle. However, no existing solutions were found for this task. Therefore, a spatial data storage platform that would support the research needed be implemented. This thesis used the design science research process to implement the solution and communicate the implemented solution and gained knowledge to other engineers and researchers that are working with similar problems. The data storage platform was implemented using opensource projects such as PostGIS, GDAL, QGIS, and SNAP. The supported research was a success thanks to the data storage platform, and it produced a scientific research article, thus demonstrating and validating the success of the solution. A preprint version of the research article is attached to this thesis report.
