When Geomosaic was created, there was only a limited set of mosaicing tools available, on all of which were deemed insufficient. The goal of the project was to have a tool which when given a region and a date range automatically, stitches together the cloud free regions of satellite imagery into a mosaic. The method of stitching is called “spatio-temporal”, as all available pixels within the region of interest and the date range are considered.

Geomosaic was originally developed as part of creating a basemap for NMBU and their remote sensing mapping and forest ecology supervision. A few requirements were set out, mainly that it would be able to use open-access data such as Sentinel-2 and Landsat and that the pixels in the output mosaic were traceable and unmodified.


With the current version of Geomosaic we can quickly generate cloud-free mosaics for a given region anywhere in the world by only providing a region of interest and a date range. Further, the selection criteria for the pixels in the output mosaics can be modified by the user, allowing specific tailoring to the specific task.
