Multi-Region Forest Delineation Dataset for Southwestern Saudi Arabia

This authoritative dataset provides precise spatial delineation of forested areas across five key administrative regions of Saudi Arabia (Al-Baha, Asir, Makkah, Jazan, and Al-Madinah). The data was developed through a hybrid methodology combining: Initial Delineation: High-resolution interpretation of Google Earth imagery (2022-2023) using FAO's Global Drylands Assessment protocols Ground Truthing: Comprehensive field validation conducted by NCVC regional offices (2023-2024)Precision Mapping: Differential GPS surveys (Trimble Geo7X) achieving sub-meter accuracy for boundary confirmation Key Features: Coverage: 27 designated forest areas totaling 1,850 km²Attributes:Forest type (Juniperus/Acacia/Mixed)Canopy density (Low/Medium/High)Protection status (Crown Lands/Protected Areas)Survey date Precision: Boundary accuracy ±3m (GPS-confirmed areas)Quality Assurance:3-tier validation process (remote, field, office)95% of boundaries ground-verified Discrepancy log maintained for unverified segments
