[Gdal-dev] Re: RFC 10

[Geo Aspects Dev]

Hi,

i was rather hoping this RFC would help me to provide a kind of map  
browser interface
eg pass each file in a directory (or any file list for that matter)  
and have GDAL/OGR driver say which it would be able to open, so i  
could highlight (or make selectable) only those "genuine" map files.
Not sure how that would work, if I needed to provide options/ 
parameters up front?

just my specific perspective on this of course ...

Tim
