The NDVI Max service is a simple, yet powerful tool with various application possibilities in the framework of land monitoring and land use. The service is developed within the Earth Observation Adding Value Services (EO VAS) project, in close cooperation with GeoVille, a high-tech company providing innovative geo-information solutions.

How Does It Work?

NDVI Max service reduces cloud contamination for over land Sentinel 2 L1C images by scanning through the whole available archive in the requested timeframe. It then returns the highest NDVI pixel values of the stack. Since no pre-processing is required this can be done in real-time and by that allows in an easy way to perform extensive systematic testing and parameter studies, also on large areas.  

Use Cases

This service is most valuable in regions with high vegetation and has various use cases, e.g. to create cloud-free background layer or as input layer for more advanced services like change detection, growth monitoring or basic classification methods.

Project Partners

Project foundation is built around Sentinel Hub Operational Prototype and Geoville’s extensive set of processing algorithms (applied in over 100 existent EO VAS). More about the project can be found here.

Project has received funding from European Union's Horizon 2020 Research and Innovation Programme under the Grant Agreement 755899.
