108 r.in.bin allows the user to create a (binary) GRASS raster map layer
109 from a variety of binary raster data formats.
110 The -s flag is used for importing two’s-complement signed data.
112 The -h flag is used to read region information from a Generic Mapping
114 Tools (GMT) type binary header. It is compatible with GMT binary grid
115 types 1 and 2.
116 The north, south, east, and west field values are the coordinates of
118 the edges of the geographic region. The rows and cols values describe
119 the dimensions of the matrix of data to follow. If the input is a GMT
120 binary array (-h flag), the six dimension fields (north, south, east,
121 west, rows and cols) are obtained from the GMT header. If the bytes
122 field is entered incorrectly an error will be generated suggesting a
123 closer bytes value.
124 r.in.bin can be used to import numerous binary arrays including:
126 ETOPO30, ETOPO-5, ETOPO-2, Globe DEM, BIL, AVHRR and GMT binary arrays
127 (ID 1 & 2).
128
130 If optional parameters are not supplied, r.in.bin attempts to calculate
131 them. For example if the rows and columns parameters are not entered,
132 r.in.bin automatically calculates them by subtracting south from north
133 and west from east. This will only produce correct results if the
134 raster resolution equals 1. Also, if the north, south, east, and west
135 parameters are not entered, r.in.bin assigns them from the rows and
136 columns parameters. In the AVHRR example (see below), the raster would
137 be assigned a north=128, south=0, east=128, west=0.
138 The geographic coordinates north, south, east, and west describe the
140 outer edges of the geographic region. They run along the edges of the
141 cells at the edge of the geographic region and not through the center
142 of the cells at the edges.
143 Eastern limit of geographic region (in projected coordinates must be
145 east of the west parameter value, but in geographical coordinates will
146 wrap around the globe; user errors can be detected by comparing the
147 ewres and nsres values of the imported map layer carefully).
148 Western limit of geographic region (in projected coordinates must be
149 west of the east parameter value, but in geographical coordinates will
150 wrap around the globe; user errors can be detected by comparing the
151 ewres and nsres values of the imported map layer carefully).
152 Notes on (non)signed data:
154 If you use the -s flag, the highest bit is the sign bit. If this is 1,
156 the data is negative, and the data interval is half of the unsigned
157 (not exactly).
158 This flag is only used if bytes= 1. If bytes is greater than 1, the
160 flag is ignored.
