‍The Minimal Sampling Classifier (MiSa.C) is an innovative web service for the classification of remote sensing raster image data, which allows the classification of complex surfaces in space and time.
‍
MiSa.C is a three-step classification process via a web-app running in the cloud. Either via parameter tuning or through a threshold to control the delineation of the land cover class, MiSa.C assists users with different levels of expertise during the classification process.
‍
The user has to upload data. There are two types of data:
* Reference data
* Satellite image stack
‍
For the satellite image stack, the user also has the option to request the data via a download service, see 2. (b). GFZ reserves the right to terminate this download service without immediate effect and without giving reasons. You can download the results of the data you have uploaded as processed by our Services at the end of the processing from your workspace. Each user can create up to 15 workspaces.‍
