I’m trying coregistraion for 2 ALOS-2 SLC L1.1 products with SNAP4.0. But the result didn’t much well. I want know how should i set the parameters in SNAP will be exact?
In default of [Coregistration], set the image in 0307(date) as master, and 0411 as Slave.
- In the option of [CreateStack], resampling type is “None”, Initial Offset Method is “Orbit”, Output Extents is “Master”.
- [Cross-Correlation] Number of GCPs is 2000, “Apply Fine Registration for SLCs” was checked, the rest are all in default.
- [Warp] is all default.
