Data product name and description
Kanopus-V is an Earth-observation, minisatellite mission of the Russian Space Agency, Roskosmos and ROSHYDROMET/Planeta.
The Kanopus-V1 spacecraft and its payload became operational in August 2013.
The overall objective is to monitor the Earth's surface, atmosphere, ionosphere, and magnetosphere to detect and study the occurrence probability of strong earthquakes.

A Kanopus-V 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.
The file name convention of Kanopus-V data is described as follows, based on a sample file name of fr_KV1_19273_19271_01_3NP2_20_T_S_035910_030616_3.tiff.
| File name segment | Description |
|---|---|
| fr_KV1 | Spacecraft designation (KV1 = Kanopus-V) |
| 19273 | Number of information-transmitting pass |
| 19271 | Number of imaging pass |
| 01 | Number of target equipment power-up session on imaging pass |
| 3NP2 | Information-transfer mode |
| 20 | Information-reception-point code |
| T | Processing level code:
|
| S | Color image attribute:
|
| 035910_030616 | Time and data output image file created |
You can open a Kanopus-V data set by selecting the fr_KV1_*.xml file.
When opening a Kanopus-V data set, the files read by GDB are as described in the following table.
| File name | Format | Required | Contents/details |
|---|---|---|---|
| fr_KV1_*.xml | Extensible Markup Language | Yes | Key file name, contains data set metadata. |
fr_KV1_*.tiff |
GeoTIFF | Yes | Image data.
Multispectral data is currently distributed as follows:
|
| fr_KV1_*_OB.jpg | Joint Photographic Experts Group | Yes | Image-thumbnail file. |
Returned data for supported format
Kanopus-V data can be opened directly in its raw vendor format or imported into a PCIDSK (*.pix) file using the key file name (fr_Kv1__*.xml). For optimal processing, use the PCIDSK format.
The following table describes the data structure after it is opened by GDB.
