Data product name and description

By using an onboard multispectral imaging system, KazEOSat-1 produces multispectral images (blue, green, red, and NIR) and panchromatic (PAN) images with a ground sample distance (GSD) of 1.0 meters to 2.5 meters and a swath width of 10 kilometers to 60 kilometers.

Note: The information provided herein is based on the data distributor's documentation cited under References.

Spectral bands:
Spectral range (nm)

Spatial resolution (m)*
(spectral resolution)

Maximum image dimensions
(Across track x along track, km)

Notes

B1 (PAN): 450 - 520
B2 (Blue): 450 - 520
B3 (Green): 530 - 600
B4 (Red): 620 - 690
B5 (NIR): 760 - 890

PAN: 1.0 m to 2.5 m
MS: 4 m to 10 m

Swath width from 10 km to 60 km at nadir depending on GSD and number of detectors. N/A

* Resolution is always nadir position unless noted otherwise.

KazEOSat-1 image data is available at one processing level:
  • Level 2

Distribution disk files

A KazEOSat-1 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 open a KazEOSat-1 data set by selecting the DIMAP (.dim) file.

When opening a KazEOSat-1 data set, the files read by GDB are as described in the following table.

File name Format Required Contents/details
*.dim DIMAP Yes Key file name. Use this file to open the data set.
*.tif GeoTIFF Yes Image data, one file per spectral band.
*.jpg JPEG No Overview file.
*.xsl Style No Style file.
*.jpg JPEG No Thumbnail icon.
rpc.xml (Level 2 with RPCs only) Extensible Markup Language Yes (for RPC model) RPC file data.

Returned data for supported format

KazEOSat-1 data can be opened directly in its raw vendor format or imported into a PCIDSK (*.pix) file using the key file name (*.dim). For optimal processing, use the PCIDSK format.

The data structure, after it is opened by GDB, is as described in the following table.
