Add helper to interpolate on GCPs #114

Closed alexamici closed 2 years ago

alexamici commented 2 years ago

The SLC IW encoding is so contorted that interpolating the values on the busts is extremely tricky., see the tortured history of #113.

This is a dependency on #54 .

After thought the main point is not to use line and pixel.

Interpolation in the form: 

gcp_ds.latitude.interp(azimuth_time=azimuth_time, slant_range_time=slant_range_time)

with method="linear" and method="nearest".

Closing.
