102. InSAR Closure Phases over South Spain Agricultural Areas: Observations and Modelling

Agriculture

A recent study demonstrates that closure phases ($\Phi_{123}$), constructed by a circular summation of three interferometric phases, have a geophysical component [1]. Constructing closure phases with consecutive 6-day Sentinel-1 acquisitions that are interferometrically multilooked, we observed consistent positive annual mean closure phases in South Spain agricultural areas. Taking corn fields...

96. UNDERSTANDING THE IMPACT OF PLANT ROW ORIENTATION ON SENTINEL-1 BACKSCATTER TIME-SERIES OF AGRICULTURAL FIELDS

Linara Arslanova (Friedrich-Schiller University of Jena)

Agriculture

The number of applications using SAR backscatter time series for crop production and monitoring has increased in recent years, and understanding of the radar signal’s interaction with different crop types in experimental and theoretical studies has improved. However, there is still a lack of information concerning different parameters, such as row orientation, especially for Sentinel-1. The...

94. Polarimetric Decomposition Using A Physics-Based ML Approach: A Sensitivity Analysis For Soil Moisture Retrieval

Lorenzo Giuliano Papale (Tor Vergata University of Rome)

11/16/23, 4:00 PM

Agriculture

The agricultural asset is facing a transition towards an increasingly sustainable resources management. In this context, soil moisture represents a key geophysical variable for many precision farming applications such as smart irrigation and crop yield estimation. Synthetic Aperture Radar (SAR) has been demonstrated to be one of the most valuable sources of information for accurate and...

76. Modelling Biophysical Parameters of Alpine Grassland from Sentinel-1 SAR and Sentinel-2 Data using Spatial Gap-filling

Caroline Göhner (Eurac Research, Institute for Earth Observation, 39100 Bolzano, Italy)

11/16/23, 4:20 PM

Agriculture

As part of the Grassland Research and Innovation Lab within the Horizon Europe project ScaleAgData (https://scaleagdata.eu/en), we assess the potential of Sentinel-1 (S1) SAR data to enrich the time series of grassland biophysical parameters derived from Sentinel-2 (S2) optical data in South Tyrol and Trentino, in North-Eastern Italy. Many studies have demonstrated the potential of SAR data in...

75. Case studies on the retrieval and classification of agricultural parameters

Francesco Mattia (CNR-IREA)

11/16/23, 4:40 PM

Agriculture

To promote the efficient and fruitful use of water, land, and energy in sustainable agriculture, knowledge and sophisticated management are required. Earth observation (EO) products with high spatial and temporal resolution have been useful in observing agricultural processes and assisting effective management. They will support the shift to green agriculture when included in sophisticated...

62. TanDEM-X for Tree Height Mapping in the Parklands of Burkina Faso

Maciej Soja (Wageningen Environmental Research)

Forestry

Mapping of tree height is of great importance for management, planning, and research related to agroforestry parklands in Africa. In this work, we study spotlight-mode TanDEM-X data for tree height mapping in Saponé, Burkina Faso, a test site characterised by a low average canopy cover (~15%) and a mean tree height of 9.0 m. Seven TDM acquisitions from January-April 2018 are used to create...
