DESCRIPTION
r3.in.bin allows a user to create a GRASS 3D raster map from a variety
of binary 3D raster data formats.
The top, bottom, north, south, east, and west field values entered are
the coordinates of the edges of the geographic region. The depths,
rows and cols field values entered describe the dimensions of the ma-
trix of data to follow. If the bytes field is entered incorrectly an
error will be generated suggesting a closer bytes value.
NOTES
The write order of the rows (north->south to south->north) and the
write order of the depths (bottom->top to top->bottom) can be switched.
Have a look at r3.out.ascii to manual page that describes the internal
layout of the 3D raster maps and the supported row and depth switch op-
tions.
Import of little and big endian byte order as well as signed and un-
signed integer data types is supported.
Example
First we create a specific region and a 3D raster map that we will ex-
port with r3.out.bin and import again.
g.region w=0 e=180 s=0 n=90 b=0 t=100 res3=10
r3.mapcalc expr="test_out_bin_float = float(if(row() == 2, null(), row()))"
r3.out.bin input=test_out_bin_float byte=4 null=-9999 \
output=test_out_bin_float_native_b4.bin order=native
r3.in.bin output=test_in_bin_float byte=4 null=-9999 \
input=test_out_bin_float_native_b4.bin order=native \
bottom=0 top=100 west=0 east=180 south=0 north=90 \
cols=18 rows=9 depths=10
