Terms of Service

These Terms of Service apply to the Minimal Sampling Classifier MiSa.C., developed, hosted and maintained by FERN.Lab, GFZ, Helmholtz-Centre Potsdam - German Research Centre for Geosciences, a Public Law Foundation under the laws of the Federal State of Brandenburg/Germany, Telegrafenberg, 14473 Potsdam, Germany, Mail: fernlab@gfz-potsdam.de (in the following “GFZ”).

You must agree to the following Terms of Service to use MiSa.C for a testing period of 3 months:

1. What is MiSa.C?

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.

2. Scope of license, third-party content

(a) Copyright and usage rights

The application consists of MiSa.C and the underlying Habitat Sampler (HaSa). MiSa.C and HaSA were created by employees of GFZ, German Research Centre for Geosciences. GFZ is the owner of all intellectual property rights to use and exploit MiSa.C and HaSa.

You are requested not to make the Sentinel-2 data downloaded on your request by the MiSa.C Services available for download elsewhere, neither to redistribute or to commercialize it or any derivatives of it.

Certain MiSa.C data layers, the base layers in the map, are subject to additional terms of use which you must comply with. These are
