#### Topic: Problems with GCP

Hi again

I am using the old version of cosis-corr, it is running in an 64bits Windows version (not sure this is the problem), and I am finding the following problems:

a/ once the tie points have been choosen the second step, converting tie points to gcps reports that points are out of the dem.

However I can check the relations beetween the DEM and the subset of the Spot scene using Globalmapper and the scene is nicely inside the DEM..

I have changed the envi header setting the "Map Info" parameter to 1, instead of 1.5 for DEM, SPOT subset and for the shading of the DEM (it has been made using the dem and the illumination elevation and azimuth reported in the ANC file). It solved the problem but then I set the geographical corners of the three elements: shade, dem and spot to start in 1 and the problem arises again.

b/ Once I have been able to get the gcps file with correct altitudes, I went to the gpcs optimization, but this time show the following message:

and this is the end.

I am trying to download the new version of COSIS-corr, I went through the registration procedure and I can see that an email will be sent to my email to download before next saturday March ,16. But I do not get any email at any of my three attempts.

My address is right now: rvgeigen@movistar.es, it may be that the mail have been sent to my old address.

I know that sounds like a "comedie d'errors" and present my excuses... but such is life!

Best regards
