Extent of several (500+) TIFF images

[Bruno Patini Furtado]

I'm using a layer of more than 500 tiff files containing DEM information of
a great area. I have created a tile index of all these maps using the
gdaltindex
program to use as a layer in my mapfile. It generated a .shp file along with
a .dbf as expected.

I'm having problems to find the proper EXTENT to my map file that will for
the moment only use the layer described above. Is there any easy way to get
full extent of these images or shapefile? The utility program gdalinfo gives
me proper information to build the extent of a single raster file, but I'm
not aware of a tool that gives this kind of information of a shape file.

I've tried to use OpenJUMP [http://openjump.org] to hover the mouse over the
min and max points of the shapefile but I had no success using the
coordinates it gave me.

Any suggestions?
