Abstract：
The Nigerian Oasis is located around Lake Chad in the southern of the Sahara Desert, between 11°11′39″N and 13°42′52″N, 8°37′28″E and 14°11′53″″E. Due to the presence of Lake Chad, this area has formed a relatively humid micro-environment, which supports vegetation growth and human activities. The total area is 19,932.49 km² (Albers). It is composed of 12 individual oases. Among them, the largest oasis covers an area of 15,085.32 km². The dataset was developed based on Google Earth 2020 imagery and related maps. The dataset is archived in .kmz and .shp data formats, and consists of 17 data files with data size of 19.5 MB (Compressed into 2 files with 8.39 MB).
