R Documentation

Resample Di-ZTD to phase cell resolution and match raster extents.

Description

Resample Di-ZTD to phase cell resolution and match raster extents.

Usage

d.ztd.resample(unw_pha, dztd, method = "bilinear")

Arguments

`unw_pha`	Un-wrapped InSAR tile/raster.
`dztd`	Di-ZTD.
`method`	Raster resampleing method "ngb" for nearest neighbor or "bilinear" for bilinear interpolation
