I have a number of TAB and TIF files. They form a single coverage. What I want to do is to convert all of them into a single GeoTIFF file, using GDAL tools, but I do not know how. I looked through dozens of threads, tutorials and etc., and it seems like GDAL supports TAB and TIF files, though I could not find any real example.

Let's suppose I have such files - one.tab, one.tif, two.tab, two.tif and want to get output.tiff. What GDAL utility should I use for this purpose and how the command would look like?– JacobianCommented Mar 22, 2017 at 15:25

I believe you can find something useful among these answers gis.stackexchange.com/search?q=gdal+mosaic– user30184Commented Mar 22, 2017 at 15:29

I've already scanned through dozens threads, but could not find anything relative to TAB/TIF pair– JacobianCommented Mar 22, 2017 at 15:33

You could make a virtual mosaic of all .tab and .tif files using gdalbuildvrt and then convert the resulting VRT file to GeoTIFF with gdal_translate:
gdalbuildvrt -input_file_list my_list.txt mosaic.vrt
gdal_translate mosaic.vrt mosaic.tif
where my_list.txt is the input file list.

Many thanks! Would you be so kind to clarify the format of my_list.txt file. Should files go one by one in a single line or in a column. And should I list there just tif files or file names without extension?– JacobianCommented Mar 22, 2017 at 15:36

And one tiny and I think the very last question - what if my tab files have coordinates in some local system and what I know about it is just proj4 formula. In other words I deal with a system which does not have a know SRID. Though, I know very well its proj4 formula– JacobianCommented Mar 22, 2017 at 15:40

@Jacobian The files should be listed one by one in a single column with their relative path and extension. They should also have projection info attached in order to be mosaicked correctly. Commented Mar 22, 2017 at 15:43

Thansk! By files you mean just tif files or tab files as well?– JacobianCommented Mar 22, 2017 at 15:45

Alternatively, if all your files to be mosaicked are contained in the same directory, you can simply execute something like:
gdalbuildvrt mosaic.vrt *.*without creating an input file list. Commented Mar 22, 2017 at 15:47
