Mosaic products
As the reference dataset by the ALOS Kyoto and Carbon Initiative Project, two products are being created, i.e.,
1) PALSAR 50m Orthorectified Mosaic Product.
2) PALSAR 500m Browse Mosaic Product.
Former product is created from the ascending path for dry and wet seasons or summer and winter seasons globally, and the latter is created as the quick look mosaic for visually checking the images acquired. Except for the resolution, both images can be converted to the normalized radar cross section in decibel. These images can be updated to this home page as they are created and they can be visualized by the following methods. The main purpose of the ALOS Kyoto and Carbon initiatives are to interpret the forest originated carbon quantity and its changes, and monitors the global land changes for forest, wetland, and desert area. Using this home page, the current earth environmetal change can be observed.
Fig. 1 PALSAR 50m Orthorectified Mosaic Image
Fig. 1 is example of the image. This is color composite of R= HH polarization, G=HV polarization, B=HH/HV polarization image. Greenish color shows a forest and purple color shows deforest or not a forest area.
Fig. 2 Expanded image of riau province in eastern Sumatra
This is expanded image of part of Fig.1. This image shows Riau province of eastern Sumatra where remarkable for deforestation. JAXA will keep monitoring these area for twice a year.
Downloading products and browsing images
Data files (Raw format) and image files (PNG format) are available via each clickable map by FTP.
KML file is also available for browsing the mosaic image by using Google Earth or NASA World Wind.

This product covers over Asia and Oceania regions by mosaicing PALSAR data which is resampled into 50m*1 from original data. The product will be made once a year. Following observation mode is used for the product.
*1. Mosaic images are projected into geographical latitude and longitude coordinates. So the spatial resolution of 50m is corresponded to 1.6170 sec.
*2. HH and HV polarization data are kept in BSQ format. Color composition of the image data is R=HH, G=HV, B=HH/HV and enhanced.
