That depends on what you got. If you have a list of points in map
coordinates and the same points in pixels then they can be computed
with linear regression. I believe gdalwarper does it for example.
You can do it yourself too with various tools.<br>
<br>
Otherwise you just use whatever metainformation you have and do the
math.<br>
<br>
It is not clear in your question whether you want to do the
calculation or are you asking how GDAL/some other software
calculates the geotransform.<br>
<br>
