Data product name and description

SuperView-1/2 is also known as GaoJing-1/2. The objective of the SuperView-1/2 satellites is to provide imagery with panchromatic resolution of 0.5 meters and multispectral resolution of 2 meters on a swath of 12 kilometers. The spacecraft are very agile and provide multiple collection modes, including long strip, multiple strips collect, multiple point targets collect, and stereo imaging. The maximum single scene can be 60 kilometers by 70 kilometers of video data.

The SuperView Neo 1 satellites were designed and manufactured by the China Association for Science and Technology (CAST). The company is developing a SuperView Neo satellite system, a successor of the existing SuperView-1 constellation. The SuperView Neo constellation will include at least 28 satellites of 3 series. The first unit is called SuperView Neo-1 and it aims to provide 0.2 ~ 0.3m(pan) or 1.2m(ms) optical images.

Distribution disk files

You can open a SuperView-1/2 or SuperView NEO-1 data set by selecting the SV1(2)-*-MUX.xml file or SV1(2)-*-PAN.xml file.

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.

When opening a SuperView-1/2 or SuperView NEO-1 data set, the files read by GDB are as described in the following table.

Returned data for supported format

SuperView-1/2 data or SuperView NEO-1 can be opened directly in its raw vendor format or imported into a PCIDSK (*.pix) file using the key file name (SV1-*-MUX.xml or SV1-*-PAN.xml). For optimal processing, use the PCIDSK format.

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