The dataset contains vegetation type in the middle reaches of the Heihe River Basin, which was used to validate products from remote sensing. It was generated from investigating the land cover strips of CASI during 2012.
Instruments: High-precision handheld GPS (2-3 m) and digital camera were used as main tools in the survey.
Measurement method: Hierarchical classification is applied based on CASI...

HiWATER: Land cover map of Heihe River Basin

DOI:10.3972/hiwater.155.2014.db Submitted Date: 2014-05-15 Published Date: 2014-05-15

The datasets of “Land Cover Map of Heihe River Basin” provide monthly land cover classification data in 2012-2013. The HJ-1/CCD data with both high spatial resolution (30 m) and high temporal (2 days) frequency was used to construct the time series data. The NDVI curves from the time series HJ-1/CCD data can depict the variation of typical land surface. Different land use type has different NDVI c...

The Second Glacier Inventory Dataset of China (Version 1.0)

DOI:10.3972/glacier.001.2013.db Submitted Date: 2014-05-10 Published Date: 2014-05-10

This dataset contains the contemporary glacier inventory of China, which was compiled totally based on Landsat TM/ETM+ imageries acquired around 2007. All the Landsat imageries were obtained from USGS websites (http://glovis.usgs.gov, and http://earthexplorer.usgs.gov). The glacier outlines in this dataset were semi- automatically extracted by widely used band ratio segmentation methods and improv...
