[Gdal-dev] How to read geotiff file using GDAL

[mchapman at texelinc.com]

If you look carefully at www.gdal.org you will find many helpful tutorials that will show you how to open and examine a tif file.  The methods to open and deal with imagery are the same for all image types.  Meaning, you open an erdas imagine file the same way you open a geotiff.

Thanks For reply Frank...........

But I am confused how this will happen..........

I didn't found any code on net which shows how to read the geotiff files and
extract information from it.......

Can u help me in regarding how to read .tif extension files and extracting
information. 

If any link you can provide me then it will be very helpful............
