The Musaicum West Asia
The Musaicum West Asia is a regional visible color satellite image mosaic of the West Asia region and adjacent areas in eastern Europe with a ground resolution of 10m. It combines recent Sentinel-2 satellite imagery into the highest quality and most cloud free depiction of the region in this resolution class available today.
It is generated using a classical mosaicing process derived from the methods and techniques developed for local mosaics but with a high degree of automatization. This eliminates most of the time intensive manual steps while maintaining high quality standards.
Compared to the Green Marble the Musaicum West Asia offers much higher spatial resolution (10m compared to 250/300m) at the cost of slightly more heterogeneous coloring due to the smaller data basis. Cloud occurrence is comparable to my hand produced local mosaics with less than about one in 100k pixels significantly affected by clouds.
Compared to the Musaicum EU-Plus this mosaic is based on improved aggregation techniques to take into account the particularities of the more arid and subtropical climate zones. Significant effort was put into representing the vegetation maximum in a setting with widespread year-to-year variability in precipitation and vegetation.
Primary data source for the image is Sentinel-2 imagery from 2019 to 2024.

Key properties
- Visible color mosaic of West Asia and adjacent areas (including the Caucasus region, parts of southern Russia, western Kazakhstan and Cyprus)
- 10m base resolution
- Based on Sentinel-2 data from 2019 to 2024
- Includes full coverage of lakes, coastal waters and reefs, no coverage of the open ocean
- Shows atmosphere compensated surface color, available either as linear surface reflectance values or tone mapped for direct display
- Shading compensated version can be produced on request
Product packaging
The mosaic is produced in different projections for different parts of the coverage area and is assembled in the target projection on demand. The previews of the whole mosaic shown here are in Lambert conformal conic projection, small area samples are in UTM projection. For use in web maps in Mercator projection by default a z14 grid (9.5546m nominal resolution) is provided.
The standard form of distribution of this mosaic is with an alpha channel for seamless blending with a background image for the open ocean - like the Green Marble. This is illustrated in the samples below. Other variants can be produced on request.
