ConvertToXYZ is a small tool that extracts baseline three-dimensional data into XYZ points files. It is useful, for instance, to extract baseline data to create bathymetries (or topography in land projects).

Quick Start

  1. Map a network drive to the data file (ETOPO, GEBCO, NOAA etc...).
  2. Create and edit a ConvertToXYZ.dat file. Save it in the same path of the executable.
  3. Run the executable.

Options file

WARNING: Only use integer coordinate lat/lon numbers.

FILE_TYPE: defines what type of input data (ETOPO, GEBCO, SRTM30...),
INPUT_FILENAME: input data file,
OUTPUT_FILENAME: where the results will be written,
TOP, BOTTOM, LEFT, RIGHT: Latitude and longitude minimum and maximum values (integers only!)

ETOPO2'

Here's what the options ConvertToXYZ.dat file looks like:

<begin_window>
FILE_TYPE                   : 2
INPUT_FILENAME              : Z:\etopo2.dat
OUTPUT_FILENAME             : WestIberiaET2.xyz
TOP                         : 46
BOTTOM                      : 33
LEFT                        : -14
RIGHT                       : -5
MAXIMUM                     : 1
MINIMUM                     : -9999
WRITE_AS_BATHYMETRY         : 1
CONVERT_TO_HDF5             : 0
<end_window>

SRTM30

Caution: make sure the ORIGIN_X and ORIGIN_Y correspond to the BOTTOM-RIGHT origin of the srtm30 original source file! Here's a map of srtm30 tiles.

<begin_window>
FILE_TYPE                   : 7
TOP                         : 46
BOTTOM                      : 33
LEFT                        : -14
RIGHT                       : -5
MAXIMUM                     : 1
MINIMUM                     : -9999
INPUT_FILE                  : \\kepler\DataCenter1\DataCenter\DadosBase\Oceanografia\Batimetria\SRTM30\Data\w020n40.Bathmetry.srtm
XYZ_OUTPUT_FILENAME         : WestIberiaSRTM.xyz
ORIGIN_X                    : -20
ORIGIN_Y                    : -10
<end_window>

NASA Topography

In Eurasia folder you will find NASA data for Europe. Copy the .zip files you need (or all) to your Hard Disk and unzip them.

Run the ConvertToXYZ with a structure adapted to you needs:

<begin_window>
FILE_TYPE             : 1
LEFT                  : -9.28
RIGHT                 : -9.056
TOP                   : 38.99
BOTTOM                : 38.75
INPUT_FOLDER          : D:\Dados\NASA\
XYZ_OUTPUT_FILENAME   : D:\Aplica\Trancao\Trancao.xyz
SAMPLE_POINTS         : 1
CONVERT_TO_UTM        : 1
<end_window>
