r3.in.grid3

NAME

r3.in.grid3 - Imports files in Bill Brown's grid3 format into G3D format.
(GRASS 3D Program)

SYNOPSIS

r3.in.grid3 [type = default | double | float] [precision = default | max | 0 - 52] [compression = default | rle | lzw | rle+lzw | none] [tiledimension = XxYxZ] [nv = yes | no] input = grid3-file output = g3d-map

DESCRIPTION

Parameters:

type
The default cell-type is float.
Options: default, double, float
precision
Options: default, max, 0-52
compression
Note that the none option only specifies that neither LZW nor RLE is used for compression. It does not turn off the compression all together. G3D does not support non-compressed files.
Options: default, rle, lzw, rle+lzw, none
tiledimension
Format: XxYxZ
nv
Specifies whether zeros in the grid3 file are converted to NULL-values. Conversion is performed if the value is yes. Default is no.
input
Path and name of grid3 file to be imported
output
Name of the G3D output map

NOTES

r3.in.grid3 uses float as default cell-type.

Currently, after the file has been imported, the stored values are compared with the original data. This feature is used to find bugs in the library at an early stage and will be turned off as soon as confidence has built up.
