Oasis Land Cover (Tunisia)

satellite imagery by yyy, acquired 2025-09-22 to 2025-09-23, 2996.6 cm per pixel, published on OpenAerialMap.

The identification and geolocation of oases across the Maghreb region were conducted in several steps. First, multiple digital archives were reviewed, and the available oasis locations were compiled into a single geospatial layer. The main data sources were the Lab Oasis Foundation (https://www.laboasis.org/) and S-Oases (https://oasen.sgn.one), an open-source database of oases. The attributes associated with each location were enriched with the country name, administrative level 1 and level 2 names, the nearest village, and the geographic coordinates (latitude and longitude). Second, national consultants validated the spatial accuracy of the oasis locations and the consistency of their associated attributes. Based on this validation, some points were removed, while others were repositioned or had their attributes revised. **Data creation:** 2026-10-09 **Contact points:** **Resource constraints:** This work is made available under the Creative Commons Attribution 4.0 International licence (CC-BY-4.0) **Online resources:**
