BIL Import

For each BIL file to be imported two other files should also be present. Example:

test.bil
test.hdr
test.tim

In the above example the test.bil files contains the actual data, the test.hdr describes the bil file and the test.tim file contains the date/time information for the bil file.

Contents of the hdr file:

;
; ArcView Image Information
;
NCOLS       534
NROWS       734
NBANDS      2
NBLOCKS     4
NBITS       16
LAYOUT      BIL
BYTEORDER   I
SKIPBYTES   0
MAPUNITS    CELSIUS;METERS
ULXMAP      300000
ULYMAP      300000
XDIM        100
YDIM        100

The BIL import assign a numerical id (starting at 0) to each parameter in the BIL file. This information is needed to set up the idmapping table (see below). The NRBLOCK parameter denotes the number of timesteps. As such, it is possible to have multiple timesteps in a single bil file. The NRBANDS parameter denotes the number of parameter in the file.

Contents of the tim file:

200001011200 60
200001011300 60
200001011400 60
200001011500 60

The first column in the time files contains: YYYYMMDDHHMM, the second column the number of minutes in the timesteps. The second column is presently ignored and may be omitted.

An example import configuration to import a bil file is shown below:
