GLObal WAter BOdies database（GLOWABO）were obtained based on the GeoCoverTM Water bodies Extraction Method, Charles verpoorer et al， by Landsat 7 ETM + image in 2000 ± 3 years. The water extraction method combines the principal component analysis, threshold extraction, texture feature extraction and other methods, with a spatial resolution of 15 m and an overall accuracy of 91%. The data also includes water area, perimeter, shape index, elevation and other information. In this data set, The Three River Headwater region, Pul River Basin and Yukon River Basin, are selected to provide data support for polar hydrological research in the northern hemisphere.

File naming and required software

This data product is a vector file (. SHP), which can be opened with ArcGIS version 10.0 or higher. The attribute table contains other water body information (mainly including area, perimeter perimeter, shape index SDI, elevation elevation, etc.) named in the following format: watershed abbreviation_2000, The Three River Headwater region (SJY), Pul River Basin (SIB), Yukon River Basin(Yuk), using GCS-WGS84 projection.
