Data product name and description

Gaofen 6 (GF6) is a geostationary, Earth-observation satellite in the Gaofen series of Chinese civilian remote-sensing satellites. It was launched successfully on June 2, 2018.

Consisting of multispectrum and synthetic-aperture-radar imagers, GF6 is used mainly in precision observation of agriculture, forestry-resource surveying, and other industries. The satellite is similar to the Gaofen-1 satellite launched in 2013, but with upgraded capabilities, including a 2-meter resolution panchromatic camera, an 8-meter multispectral imager, and a 16-meter multispectral wide-angle colour camera. GF6 can observe chlorophyll and other nutritional content of crops, and help to estimate crop yields.

Note: The information provided herein is based on the data distributor's documentation cited under References.
GF6 data is available in the following processing levels:
  • PMS

Distribution disk files

A GF6 data set is organized in a specific folder structure on disk. GDB uses this folder structure and the file names to identify the data product type.

Warning: Data sets for this sensor are organized in a specific folder structure on disk. GDB uses this structure and the file names to identify the data product type. Do not alter the folder structure or any file names prior to data ingestion to ensure the image data and auxiliary information are imported correctly.
You can open a GF6 data set by selecting one of the following files according to the processing level:
  • PMS: GF6_*-MUL.xml or GF6_*-PAN.xml
  • WFV: GF6_*.xml

When opening a data set, the files read by GDB are as described in the following table.

File name Format Required Contents/details

GF6_PMS_*.xml
GF6_WFV_*.xml

Extnesible Markup Language Yes Key file name, contains data-set metadata
*.tiff GeoTIFF Yes Image data
*.rpb Text Yes RPC data
*_thumb.jpg Joint Photographic Experts Group (JPEG) No Image thumbnail

Returned data for supported format

GF6 data can be opened directly in its raw vendor format or imported into a PCIDSK (*.pix) file using the key file name (GF6_PMS_*.xml, GF6_WFV_*.xml, or both). For optimal processing, use the PCIDSK format.

The following table describes the data structure after it is opened by GDB.
