Hi,
Function ProcessRecordHeaders in "formats/l1b/l1bdataset.cpp" subsamples the
GCPs of the l1b image, but the points are unordered an not equidistant.
I attached to TCK 2403 a patch that modifies this behaviour. I tested the
image attached to the ticket and seems to work ok(no error produced).

>From memory the l1b driver doesn't use enough points to get proper
geolocation because it sub-samples the 51 which are provided in the l1b
file. The best solution (that recommended by NOAA) is to use lagrange
interpolation across the 51 points. A lagrange algorithm has been provided
in the tic
Hi, I’m using gdal c++ API.
I’d like to implement an algorithm to georeference noaa L1b images(of
Argentine in particular). The number of GCPs returned by the L1b driver are
not enough to use triangulation(midcourse solution until a better algorithm
can be implemented).
