Dear All,

I am wondering whether it is possible to 'stitch' together multiple
MapInfo .MIF maps (directories) as a single vector map 
using v.in.org ?
>From what I gather from the documentation of GRASS 6.2 the following
from v.in.org's page:

MapInfo TAB and MIF/MID:
MapInfo datasets in native (TAB) format and in interchange (MIF/MID)
format are supported for reading and writing. Update of existing files
is not currently supported. 
Note: In the rest of this document "MIF/MID File" is used to refer to a
pair of .MIF + .MID files, and "TAB file" refers to the set of files for
a MapInfo table in binary form (usually with extensions .TAB, .DAT,
.MAP, .ID, .IND).

The MapInfo driver treats a whole directory of files as a dataset, and a
single file within that directory as a layer. In this case the directory
name should be used as the dataset name. 

However, it is also possible to use one of the files (.tab or .mif) in a
MapInfo set as the dataset name, and then it will be treated as a
dataset with one single layer.
