Georeferencing

Hi all I have an image; the Trimmed satellite image with Latitude and longitude coordinates from here:

http://www.maplibrary.org/stacks/Africa/Kenya/index.php

It comes with a .tfw file. (6 x 1).

How on Earth do I use the .tfw file to assign coordinates to each pixel? I have just got the mapping toolbox. Thanks

You can use worldfileread to read the data into a referencing matrix, which can then be used to calculate coordinates for any pixel in the image.

 doc worldfileread
 doc pix2map

If you just want to display the image, though, geoshow and mapshow handle tif/tfw paired files.

 tiffile = 'KEN_satellite_trimmed.tif';
 geoshow(tiffile);
