ANSI-C program: data2xyz.c
NAME
data2xyz - Convert
float data in map geometry described by a DEM_par to triplets of
float: (easting, northing, data_value) or (latitude,
longitude, data_value)
SYNOPSIS
data2xyz <DEM_par> <data> <data_xyz>
[dflg]
| <DEM_par> | (input) DEM parameter file |
| <data> | (input) float format data with same dimensions and spacing as specified in the DEM parameter file |
| <data_xyz> | (output) data triplets in 4-byte float format (northing, easting, data_value) |
| [dflg] | output data format flag: 0: binary (float) 1: text format |
EXAMPLE
data2xyz hector_utm_seg.dem_par hector_utm.diff
hector_utm_disp.xyz
generates triplets of 4-byte float data values with the
format: (northing,
easting, displacement)
data2xyz
hector_eqa_seg.dem_par hector_eqa.diff hector_eqa_disp.xyz
generates triplets of 4-byte float data values with the
format: (latitude,
longitude, displacement)
DESCRIPTION
data2xyz generates
triplets of data values with the format easting, north,
data-value. As inputs the program requires a DEM parameter
file
and a data file with the dimensions as specified by the DEM
parameter file. Output
data format is little-endian for Intel and AMD CPUs.
The data can also be output in text format by setting the value of the dflg command line parameter to 1. There will be one data point per line. These data can be compressed using zip or gzip to get significantly smaller file sizes.
The output data are compatible with the GMT generic mapping
tools http://gmt.soest.hawaii.edu/
