Descripción
GeoTIFF rasters with the following phenometrics obtained from Sentinel 2 Data:. * Start of the season Day of the Year (SOSD) * Maximun of the Season Day of the Year (MAXD) * End of the Season Day of the Year (EOSD) * Start of the season Value (SOSV) * Maximun of the Season Value (MAXV) * End of the Season Value (EOSV) These rasters have been downloaded, mosaicked and croped with Doñana Natural Space DEIMS.ID through Pyvpp python package.

Datos del proyecto
The SUMHAL project, Sustainability for Mediterraean Hotspots in Andalusia integrating LifeWatch ERIC, is a European project within the ERDF programme of actions related to the pan-European distributed e-Science infrastructure LifeWatch ERIC, with headquarters in Andalusia-Spain. It is funded by the Spanish Ministry of Science and Innovation, through the European Regional Development Funds (ERDF) [SUMHAL, LIFEWATCH-2019-09-CSIC-4, POPE 2014-2020]. The key purpose of the project is to contribute to the conservation of biodiversity in natural or semi-natural systems in the Western Mediterranean, making use of high-tech infrastructures, fieldwork, data integration and the development of virtual research environments (VREs), as well as the combination of highly specialised research staff and citizens through citizen science actions.

| Descripción del área de estudio | Doñana Long-Term Socio-ecological Research Platform (https://deims.org/bcbc866c-3f4f-47a8-bbbc-0a93df6de7b2) |
| Descripción del diseño | Remote sensing is an essential tool to carry out all these long-term ecological monitoring tasks, thanks to the collection of data through satellite, aircraft, drone and in-situ images. In this sense, in work package 6 of the SUMHAL, PhenoApp (which is the app who integrate the current and some other datastes) application has been developed, enabling the integration of phenology remote sensing data into Virtual Research Environments (VRE). This application aims to integrate data obtained in situ by eight phenocameras installed in the Doñana Natural Area by the Doñana Singular Scientific-Technical Infrastructure (ICTS-RBD) together with images from ESA's Sentinel-2 satellites (Copernicus Programme) and MODIS. |
Métodos de muestreo
These phenometric rasters have been created from the Seasonal Trajectories PPI Index gapfilled data. A product with out NoData created from and smoith curve of the real data obtained from the satellite. This gapfilled product allows the use of a mathematical approach to the phenological curve of every pixel from which phenometrics could be estimated.
| Área de Estudio | Year composites at 10 meters of spatial resolution with phenometrics for Doñana Long-Term Socio-ecological Research Platform derived from Sentinel 2 Satellite Imagery Data. |
|---|---|
| Control de Calidad | Quality control for product generation is made by Copernicus (European Spatial Agency). Besides, we apply cross validation with other satellite phenometrics derived data and with some Ground Control Data. Plus, we have 8 Phenocams distributed in Doñana National Park that are also used as ground truth data in the validation process. More info about the Copernicus product and its quality control can be retrieved here: https://doi.org/10.1016/j.rse.2021.112456 |
Descripción de la metodología paso a paso:
- We have developed our own tool to download Wekeo data, a python package called "Pyvpp" that get profite of Deims python package to just type the eLTER site ID and the tool will do the search for the intersecting Sentinel 2 Tiles, perform the download, make a mosaic and crop it with the eLTER site boundaries. After that, the phenomterics mosaics are upload to Google Earth Engine, so that they can be accessed from our application.
