Based on Prof. P. Hostert talk (Approx. 60min)
This section is based on the keynote presentation given by Professor Dr. Patrick Hostert, who is the head of the Earth Observation Lab at the Geography Department of Humboldt Universität zu Berlin, Germany (Earth Observation Lab). This presentation was recorded during the Workshop on Multi-Source Remote Sensing for Agriculture, held on September 10th 2025, at ZALF in Müncheberg, Germany.
The focus of this presentation is to discuss the importance of optical remote sensing (RS) for agriculture, particularly in the context of climate change and food security. It is divided into three main parts including the past, present and future:
The Past: Where we come from
The history of Landsat and Sentinel-2 data, highlighting the importance of open data archives and data fusion. It also discusses the role of regional differences in data density and the need for tailored approaches to agricultural monitoring.
The Present: Where we are
An overview of the current status of optical RS for agriculture, including the use of multispectral and hyperspectral data in regional and global applications. It highlights the challenges of soil-specific spectral unmixing, crop rotation and mowing detection and grassland drought monitoring.
The Future: Where we go to
This part looks to the future, discussing the potential of hyperspectral data from missions like EnMAP and the importance of enhanced spectral, spatial, and temporal resolutions. It also highlights the development of Sentinel-2 NG and CHIME, which will provide global routine data from 2029/2033 onwards.
