MontadoDB: A Comprehensive Dataset of Pasture Parameters in the Sourthern Region of Portugal

This data comprises 705 samples, including collection date and day of the year (Date and DOY), sample region (Sample), geographical coordinates (Lat and Long), and the parameters collected from the laboratory: Pasture Measure Content, Crude Protein, Neutral Detergent Fiber, Fresh Weigth, Dry Matter (PMC (%), PB (g/100g), NDF (g/100g), Kg MS/ha), with its BoxCox transformation (PMC (%)_BoxCox, PB (g/100g)_BoxCox, NDF (g/100g)_BoxCox, Kg MS/ha_BoxCox) for data normalization.

Multispectral and weather data were collected for each sample coordinate. The spectral data comes from Google Earth Engine on four satellites (Landsat-8, Sentinel-2, Sentinel-3, and MODIS) and their respective collections and tiers.

- Sentinel-2 Surface reflectance : B1, B2, B3, B4, B5, B6, B7, B8, B8A, B9, B11, B12
- Sentinel-2 Top-of-atmosphere: B1, B2, B3, B4, B5, B6, B7, B8, B8A, B9, B10, B11, B12
- Landsat-8 Surface reflectance tier 1: SR_B1, SR_B2, SR_B3, SR_B4, SR_B5, SR_B6, SR_B7
- Landsat-8 Top-of-atmosphere (tier 1 / 1 + realtime): B1, B2, B3, B4, B5, B6, B7, B8, B9, B10, B11
- Landsat-8 Raw (tier 1 / 1 + realtime): B1, B2, B3, B4, B5, B6, B7, B8, B9, B10, B11
- Sentinel-3: Oa02, Oa03, Oa04, Oa05, Oa06, Oa07, Oa08, Oa09, Oa11, Oa12, Oa13, Oa14, Oa15, Oa16, Oa17, Oa18, Oa19, Oa20, Oa21
- MODIS: NDVI, EVI

The spectral bands columns are preceded by a column that indicates the date of the collected image. Every column name highlights the type of satellite, its collection, and tier, e.g., Landsat-8_SR_1, which refers to the Landsat-8 satellite, surface reflectance collection, and tier 1.

The weather data can be acquired from Open weather and Open Meteo APIs, fetching the following weather conditions: Maximum and Minimum Temperature acquired (TEMP_MAX (°C), TEMP_MIN (°C)), Average Solar Radiation (RAD_SOL (J/M2)), Average rainfall recorded during the day (RAIN (mm)), Average Wind Speed (WIND_SPD (km/h)), Average Estimated Soil Evapotranspiration (EVAPOT (mm)), Average Atmospheric Pressure (PRES_ATM (hPa)) and Average Relative Humidity (HUM_REL (%)).

The "dataset" folder includes eight files: "Experimental_data.csv", "Sentinel-2.csv", "Sentinel-3.csv", "Landsat-8.csv", "Modis.csv", "Complete_data.csv", "Weather_data.csv", and "Satellite_info.json". "Experimental_data.csv" and "Weather_data.csv" contain only samples and weather data, respectively. "Each satellite CSV includes Forage parameters, spectral bands, and weather data. The "Complete_data.csv" merges all the other files. "Satellite_info.json" contains auxiliary satellite data for GEE and dataset build.

The "scripts" folder contains two necessary modules, one for GEE functions - "multispectral_api.py", and another for Weather API calls - "weather_api.py", and a notebook Python file ("build_dataset.ipynb") that uses both modules to fetch the data and build the dataset.
