models.- This option is to decide the mathematical model that will
be used in the calculation. We can choose between two different models:
Classical CUSTIC model and ISO-9613.
The ISO method of calculation can be used for punctual sources considering
humidity, temperature and the solid angle for the source. In the case of
roads, only angle solid effects will be considered when the ISO option is
GIS.- In this option it can be found all
necessary to work with geographical information system.
Coordinates of the origin: With this command we can choose the value for the
origin of coordinates. It is initially in the left bottom corner of the
program window. It is possible to work with geographic and Cartesian
Reference points.- With this command we
can decide the coordinate values of a point, that we previously know, in the
map in order to have a referenced system. It is possible to work with
geographical and Cartesian coordinates. After that, it will be possible to
export the results to a GIS system.
Radius of curvature.- By means of this
command, you can choose a value for the Earth radius. This radius can be
slightly modified to adjust the reference system with the available data. The
program considers the Earth as a perfect sphere with an exact radius. We know
that this is not exactly true. This option is to correct this kind of effects.
Scale calculation.- With this command it
is possible to estimate the map scale that corresponds to a background image,
that has trees previously imported by the user. It is necessary to know the
distance between to different points in the map. After introducing the
distance data, you can click consecutively both points, and the scale will be

CUSTIC. The data have been exported in EXCEL and
imported by ArcMap.
