I've downloaded most of the rdrs now so I thought I'd have a play with the data.

This is an image of the South Pole, The area shown is about 200kmx200km. I haven't tried to be accurate with the vertical scale.

Here's a contour map of the same area, the contour interval is 200m.

I'm getting severe orbit streaking when I create high resolution(~5m) gridded datasets from the RDRs. Has anyone noticed orbit streaks in the 5m resolution GDRs?

The heighest point is 2078m the lowest is -2999 m. Orbit streaks are visible but not too bad in this image because it is using a lower resolution dataset (80m).

the poles "should" be much better than the mid latitude +45 to -45
Now there is the scientific removal but that will be in a few years .When there is much more data , that can be averaged better.
There is also an"Artistic " smoothing without bluing that i used for the 256 px./ deg. full map I made .
that involved using a heat flow pde that " G'mic" ( grastoration / Cimg.h ) uses .
an example


now that is NOT near the pole and thus needs a very BIG correction
