Datasets description

  This data set includes the distribution data of national salt fields in 2013. These data are formed after the salt lake map spots are extracted by manual interpretation of Landsat satellite remote sensing images and vectorized. It mainly includes salt field name (YT), salt number (yxbh), province (SF) and other information. There are 39 records in the dataset, 56.00kb.

Data thumbnail
Data source description

  Geospatial data cloud downloads Landsat images.

Data processing method

 Through Landsat satellite remote sensing images in ArcGIS 10.3 software, the salt field map spots are manually interpreted and extracted, and the salt field distribution data in 2013 are obtained by vectorization processing.

Data quality description

  By comparing the historical data and actual field survey data with the extracted salt field distribution data, the data quality is good.
