In this section you can find mosaics generated by MOSRI, a Real Time Mosaic generation system. Images are published as soon as products covering new time periods are processed, or when certain time series focusing on a specific area of the Earth are requested by users. The mosaics are categorized by mission (Envisat, Alos, Terra, Aqua, Metop, etc.) and by sensor (Asar, Meris, Modis, etc.).

Envisat – Meris Reduced Resolution Mosaic of the World
Description
Over 2000 Level0 Reduced Resolution products from the MERIS instrument onboard the Envisat satellite were collected in the time period from January to August 2008 and processed by Chelys Satellite Rapid Response System (SRRS) to generate high quality images.
The images were projected to obtain this composite view using MOSRI, a real time mosaic generation system, which automatically removes clouds and shadows while combining the data.

Envisat – SAR Sharpening
Description
This is a Mosaic generated by Chelys MOSRI, using a technique we call “SAR-Sharpening” due to its similarity to a method known as PAN-Sharpening.
PAN-Sharpening merges high resolution panchromatic and lower resolution multispectral imagery to create a single high resolution color image. “SAR-Sharpening”, on the other hand, uses a radar image instead of a panchromatic one.
In this image, we maintained the resolution of the MERIS sensor (250m) while greatly enhancing the level of detail using an ASAR mosaic with a 75m resolution.

Envisat – ASAR Image Mode Medium Resolution
Description
This is an ASAR Image Mode Medium Resolution Mosaic generated with images acquired in the time period from January to July 2009. Source images were generated starting from ENVISAT/Asar products using the Chelys Satellite Rapid Response System and projected, orthorectified (with a NASA DEM of 3 arcseconds of resolution) and merged in this mosaic by Chelys Mosri, a real time mosaic generation system, at the original resolution of 75 meters (0.000833 degrees per pixel). The mosaic was generated in less than 1 minute.

Envisat – Meris Full Resolution
Description
These are Meris Full Resolution Mosaics generated with images acquired in the time period from April to November 2008. Source images were generated starting from ENVISAT/Meris satellite raw data using the Chelys Satellite Rapid Response System and projected, orthorectified (with a NASA DEM of 3 arcseconds of resolution) and merged in this mosaic by Chelys Mosri, a real time mosaic generation system, at the original resolution of 260 meters (0.003 degrees per pixel). The mosaic was generated in less than 2 minutes.
