[gdal-dev] Which formats are just flat binary files plus a header?

[Sjur Kolberg]

Jonathan,

The same also for the IDRISI .rst + .rdc format.
An example header (.rdc) ASCII file looks like below.
The short ref. system item names a file in a library supplied with the IDRISI distribution.
The GDAL Idrisi driver recognises a subset of these 

file format : Idrisi Raster A.1
file title  : 
data type   : real
file type   : binary
columns     : 130
rows        : 200
ref. system : utm-32n
ref. units  : m
unit dist.  : 1
min. X      : 400000.0000000
max. X      : 530000.0000000
min. Y      : 6660000.0000000
max. Y      : 6860000.0000000
pos'n error : unspecified
resolution  : 1000.0000000
min. value  : 0
max. value  : 0.66993666
display min : 0
display max : 0.66993666
