This repository provides a comprehensive, multi-source geospatial dataset covering the entire territory of Algeria. It integrates climate rasters, organism/land-cover layers, Sentinel-based indicators, parent material data, relief variables, and soil profile observations.
The dataset is suitable for Digital Soil Mapping (DSM), SCORPAN modelling, environmental analysis, and geospatial machine learning.

📦 Dataset Overview

The dataset contains the following components:

1. Climate Data (TIF)

High-resolution raster layers for key climatic variables:

tmax — Maximum temperature
tmin — Minimum temperature
srad — Solar radiation
pre — Precipitation
vapr — Vapor pressure
wind — Wind speed

These variables capture spatial climatic gradients essential in SCORPAN (“C” factor).

2. Organism & Land-Cover Data (TIF)

Ecological and anthropogenic variables representing 20 organism/land categories, including:

Amphibians
Birds
Barren land
Cultivated areas
Deciduous trees
Evergreen trees
Herbaceous cover
Human activities
Mammals
Open water
Regularly flooded areas
Reptiles
Shrubs
Slope vegetation
Snow & ice
Soil RH Mean
Soil RS CV
Soil RS CSV
Trees
Urban zones

These layers represent biological and human influences on soil distribution (the “O” factor of SCORPAN).

3. Parent Material / Rocks (TIF)

Geological and lithological raster layers describing rock types and parent material.
Represents the “P” component of SCORPAN.

4. Relief & Terrain Data (TIF)

High-resolution geomorphometric variables:

Aspect (cos, sin, east, north)
Slope
Roughness
Regularly flooded terrain

These represent local terrain controls (the “R” factor).

5. Sentinel-Based Data

Derived satellite indices from Sentinel imagery, capturing:

Vegetation patterns
Moisture variability
Surface reflectance

Useful for environmental modelling and soil surface property inference.

6. Soil Profile Data (CSV)

Soil observations collected from approximately 2000 distinct locations across Algeria, provided in two formats:

Raw, non-splined soil measurements
Splined soil properties at standard depths:
- 0–5 cm
- 5–15 cm
- 15–30 cm
- 30–60 cm
- 60–100 cm
- 100–200 cm

Soil profiles include both site metadata and detailed soil attributes.

🗺️ Resolution & Formats

Rasters are provided in GeoTIFF (.tif) format.
Soil profiles are provided in CSV (.csv) format.
Data sources have different native resolutions, depending on the original provider (climate, Sentinel, land-cover, DEM, geology, etc.).

🎯 Intended Applications

This dataset can be used for:

Digital Soil Mapping (DSM)
SCORPAN-based modelling
Machine learning / deep learning for soil prediction
Agricultural suitability analysis
Ecological and biodiversity modelling
Climate–soil interaction studies
Terrain analysis and environmental monitoring
