I'd like to use gdaltindex to create a polygon shapefile of thousands of georeferenced .tif documents. I've found this incredibly easy to accomplish in a single directory on Linux (e.g. gdaltindex indexoutput.shp *.tif) but I'll also need to index several hundred sub directories on a windows drive. I do have FWTools installed on the windows machine.
The majority of these files are Tiff's with a world file and have not yet been converted to geoTiffs. I work in a few different coordinate systems, so ideally I'd like to go through and make a single pass at each coordinate system.
It looks like I can use -skip_different_projection to take care of the projection issue, but my search hasn't turned up any parameters of gdaltindex to specify directories, so any help is much appreciated.
