Output of the application
- Subheading: Satellite line-of-sight
Basic displacement information provided by the service is the satellite line-of-sight (LOS), with projected to ground geometry and quality measures per measurement point, in radar geometry.
East-West and Up-Down deformation rates produced by combining data stemming from ascending and descending orbits. Basic displacement information data should be seen as an intermediate product, necessary in order to produce East-West and Up- Down deformation rates.
These two LOS vector components from basic displacement can be used to calculate the east-west and vertical components of movement.
East-West and Up-Down deformation products are useful for general engineers who will find them easier to interpret than LOS measurements. They will also be very useful for highlighting horizontal deformation.
