In order to cover a geographical area larger than one scene, neighbouring geocoded or orthorectified images are combined into one image in a seamless way. Such a mosaic is quickly interpretable and combinable with other sources of information and can be used for map sheet generation.
A Radar Mosaic MCSAR is a seamless assembly of adjacent images into a single, harmonised dataset. The intersection lines are specifically selected in order to avoid the visibility of cutting edges. The radiometric adjustment of all scenes results in a homogeneous image mosaic.
The MCSAR product characteristics are:
- Multilook detected geocoded / orthorectified product
- WGS 84 with standard projections UTM or UPS
- Source map depicting the relevant input image for each pixel
Subsets of mosaics can be represented as Oriented Image OISAR. These subsets are characterised by a map sheet index corresponding to relevant national mapping standards or customer-defined grid systems.
