Re-project NOAA images?

Hi, another NooB question I'm afraid.

I'd like to use some images from here:

NOAA GOES Weather Satellite

http://goes.gsfc.nasa.gov/goeseast-lzw/atlantic/vis/1004051415G12I01.tif

Is it possible to reproject them in Global Mapper?

I've read a bit about the rectification system NOAA uses. It appears to use a .nav file which describes a the coordinates for each pixel. But I haven't seen anything that looks like the name of a projection type.

Any suggestions greatly appreciated.

Thanks,

W

    The link that you provided didn't work, but you can load and rectify any TIFF file in Global Mapper just by using the File->Open Data File menu command. Once you have a properly positioned image, you can simply change the view/export projection on the Projection tab of the Configuration dialog to reproject, then use the File->Export Raster menu to export to a new file in the desired format.

    Let me know if I can be of further assistance.

    Thanks,

    Hi Mike, it has been several years.

    (1) Doing a google search for NOAA Charts brings up many links that are invalid.
    Here is a link I have found to be useful: Adding Navigation Charts to Maps in Saga: KAP, BSB, S-57
    From there you can follow links like this: https://sites.google.com/site/nauticalfree/

    I was able to download 18725(1).zip and their Nautical Chart Reprojector

    The KAP files can be viewed in OpenEV. I could not find a way to get or format to .tif which I am familiar with from working with for the FAA Charts
    How to tile the NOAA Charts to be used in the NASA WorldWind apps. Several are interested in this,; here is a link to a NASA WWJ forum thread: s-57 and s-63 - Page 2

    possibly a step by step example with explainations.

    Let me know if I can be of further assistance.

    Thanks,

    Hi, I would like to reproject a TIFF file from KKJ3 (Finnish coordinate system) to KKJ4. I was only able to find KKJ (which is presumable KKJ3 or YKJ), not KKJ4. I am using Global Mapper 13.1. Is it possible to do what I want to do in Global Mapper?

    Thank you,
