Abstract：
Land cover dataset within 40 km from coastline along Chabahar (Iran)- Ormara (Pakistan) (1990, 2000, 2010, 2017) was developed based on integrating Landsat TM/OLI images and the ecological indexes and the decision tree, as well as the supervised classification methods. Firstly, the NDVI (Normalized Difference Vegetation Index), NDWI (Normalized Difference Water Index), BSI (Bare Soil Index) and NDBI (Normalized Difference Built-Up Index) were calculated based on the Landsat TM/OLI images. And then, the land cover classification data were extracted by the comprehensive utilization above index methods, decision tree classification and supervised classification methods. Lastly, the data validation was made with Google Earth high-resolution images. The data result shows that, from 1990 to 2017, the artificial surface in the Iranian section has increased by 15 times and that in Pakistan section by 10 times. The data spatial resolution is 30 m. The dataset is consisted of 4 data files in .tif format with data size of 269 MB (Compressed to one single file, 12.0 MB).
