DESCRIPTION

       r.in.bin allows the user to create a (binary) GRASS raster map layer  from  a  variety  of
       binary raster data formats.

       The  -s flag is used for importing two’s-complement signed data.

       The   -h  flag  is used to read region information from a Generic Mapping Tools (GMT) type
       binary header. It is compatible with GMT binary grid types 1 and 2.

       The north, south, east, and west field values are the coordinates  of  the  edges  of  the
       geographic  region. The rows and cols values describe the dimensions of the matrix of data
       to follow. If the input is a GMT binary array (-h flag), the six dimension fields  (north,
       south,  east, west, rows and cols) are obtained from the GMT header. If the bytes field is
       entered incorrectly an error will be generated suggesting a closer bytes value.

       r.in.bin can be used  to  import  numerous  binary  arrays  including:  ETOPO30,  ETOPO-5,
       ETOPO-2, Globe DEM, BIL, AVHRR and GMT binary arrays (ID 1 & 2).

NOTES

       If  optional parameters are not supplied, r.in.bin attempts to calculate them. For example
       if the rows and columns parameters are not entered, r.in.bin automatically calculates them
       by subtracting south from north and west from east. This will only produce correct results
       if the raster resolution equals 1. Also, if the north, south, east,  and  west  parameters
       are  not entered, r.in.bin assigns them from the rows and columns parameters. In the AVHRR
       example (see below), the raster would be assigned a north=128, south=0, east=128, west=0.

       The geographic coordinates north, south, east, and west describe the outer  edges  of  the
       geographic  region.  They  run  along the edges of the cells at the edge of the geographic
       region and not through the center of the cells at the edges.

       Eastern limit of geographic region (in projected coordinates must  be  east  of  the  west
       parameter  value,  but in geographical coordinates will wrap around the globe; user errors
       can be detected by comparing the  ewres  and  nsres  values  of  the  imported  map  layer
       carefully).
       Western  limit  of  geographic  region  (in projected coordinates must be west of the east
       parameter value, but in geographical coordinates will wrap around the globe;  user  errors
       can  be  detected  by  comparing  the  ewres  and  nsres  values of the imported map layer
       carefully).

       Notes on (non)signed data:

       If you use the -s flag, the highest bit is the sign  bit.  If  this  is  1,  the  data  is
       negative, and the data interval is half of the unsigned (not exactly).

       This flag is only used if bytes= 1. If bytes is greater than 1, the flag is ignored.

EXAMPLES

   GTOPO30 DEM
       The following is a sample call of r.in.bin to import GTOPO30 DEM data:

       r.in.bin -sb input=E020N90.DEM output=gtopo30 bytes=2 north=90 south=40
       east=60 west=20 r=6000 c=4800

       (you can add "anull=-9999" if you want sea level to have a NULL value)

   GMT
       The following is a sample call of r.in.bin to import a GMT type 1 (float) binary array:

       r.in.bin -hf input=sample.grd output=sample.grass

       (-b could be used to swap bytes if required)

   AVHRR
       The following is a sample call of r.in.bin to import an AVHRR image:

       r.in.bin in=p07_b6.dat out=avhrr c=128 r=128

   ETOPO2
       The following is a sample call of r.in.bin to import ETOPO2 DEM data (here full data set):

       r.in.bin ETOPO2.dos.bin out=ETOPO2min r=5400 c=10800 n=90 s=-90 w=-180 e=180 bytes=2
       r.colors ETOPO2min rules=terrain

   TOPEX/SRTM30 PLUS
       The following is a sample call of r.in.bin to import SRTM30 PLUS data:

       r.in.bin -sb input=e020n40.Bathymetry.srtm output=e020n40_topex \
                bytes=2 north=40 south=-10 east=60 west=20 r=6000 c=4800
       r.colors e020n40_topex rules=etopo2

   GPCP
       The following is a sample call of r.in.bin to import GPCP 1DD v1.2 data:

       YEAR="2000"
       MONTH="01"
       # number of days of this month
       MDAYS=`date -d"${YEAR}-${MONTH}-01 + 1 month - 1 day" +%d`
       r.in.bin in=gpcp_1dd_v1.2_p1d.${YEAR}${MONTH} out=gpcp_${YEAR}.${MONTH}. \
                order=big bytes=4 -f header=1440 anull=-99999 \
                n=90 s=-90 w=0 e=360 rows=180 cols=360 bands=$MDAYS

       The following is a sample call of r.in.bin to import GPCP v2.2 data:

       r.in.bin in=gpcp_v2.2_psg.1979 out=gpcp_1979. \
                order=big bytes=4 -f header=576 anull=-99999 \
                n=90 s=-90 w=0 e=360 rows=72 cols=144 bands=12
