Project Summary

Implementing the PROAGROBURO project ([i]) within the framework of the PROBA-V Preparatory Programme chaired by the PROBA-V International Users Committee (IUC). The main objective of the Project was to assess the quality of the PROBA-V mission as a continuity mission to VEGETATION 1 & 2 by comparison and validation of SPOT VEGETATION and PROBA-V simulated data (SD) for assessing crop status on chosen test areas on the territory of Bulgaria and Romania, Fig. 1 (1). As a result of implementing the project methodology, the following has been achieved: 1) developing methodological requirements; 2) composing a geodatabase with integrated satellite and in situ biophysical and biometric reference data; 3) conducting sub-satellite experiments; 4) developing empirical models describing the relationships between crop data obtained from simulated PROBA-V data (courtesy VITO) and in situ reference data; 5) composing land use/land cover (LU/LC) maps based on unsupervised and supervised image classification of SPOT VEGETATION and PROBA-V images; 6) determination of crop status based on the NDVI, NDWI and LAI indexes from SPOT VEGETATION data and PROBA-V SD. The project partners were: the SRTI-BAS, the Romanian National Meteorological Administration (RNMA), and the National Institute of Meteorology and Hydrology at the BAS (NIMH-BAS). As a result it was found that PROBA-V mission will provide better results in LU/LC classifications of agricultural environments compared to SPOT VEGETATION. The significant correlations of PROBA-V SD, vegetation indices (VIs), and biophysical products with ground-measured biophysical and biometrical parameters provide to improve the monitoring of winter crops with additional products from PROBA-V. The main findings and deliverables of the project were presented and published in a series of conference proceedings and peer-reviewed journals ([ii],[iii],[iv],[v],[vi],[vii],[viii]).
