[Gdal-dev] BigTiff and libtiff

[Garrett Potts]

Hello Frank:

I am just thinking of different Open SPEC ways that already exist  
that we can take Video where each frame is tagged with a geospatial  
component.  So fast random access is not needed but sequential frame  
per frame access could be.  Most examples I am seen probably would  
not exceed 1000 or so frames per day but didn't want a limit to hat  
to exist on down the road.

Think of storing all frames and geospatial taggs ( orientation, frame  
parameters, ... etc) per directory where eac h directgory is a single  
frame. We can then have things like:

flight<data>.tif

to indicate a flight run on a single day.  If we are capturing at  
around 1 per second then this can get large.


Take care

Garrett
