margin-bottom:.0001pt;text-align:justify'>GEOTRANS (Geographic Translator) is
110
an application that allows you to convert geographic coordinates among a wide
111
variety of coordinate systems, map projections, grids, and <span class=SpellE>datums</span>.
112
GEOTRANS runs in Microsoft Windows (95, 98, 2000, NT, and XP), LINUX and UNIX
113
Motif environments.</p>

<p style='margin-top:6.0pt;margin-right:0in;margin-bottom:0in;margin-left:0in;
116
margin-bottom:.0001pt;text-align:justify'>The user interface of GEOTRANS
117
consists primarily of a single window. To convert coordinates, select the coordinate
118
reference frame and datum in which your coordinates are defined, enter any
119
associated parameters, and enter the coordinates in the upper half of the
120
window. Then select the coordinate reference frame and datum to which you want
121
the coordinates to be converted, and enter any associated parameters, in the
122
lower half of the window. Click on the Convert: Upper-to-Lower <span
123
class=GramE>button,</span> and the resulting coordinates will be displayed in
124
the lower half of the window. You can convert additional coordinate sets from
125
the same source by just entering the new coordinates and clicking on the
126
Convert: Upper-to-Lower button. You can change the coordinate reference frame,
127
datum, or parameter selections at any time. Also, you can reverse the roles of
128
input and output by using the Convert: Lower-to-Upper button. Currently, thirty-four
129
different types of coordinate systems, map projections, grids, and coding
130
schemes are supported, as well as more than two hundred different horizontal <span
131
class=SpellE>datums</span>.</p>
133
<p style='margin-top:6.0pt;margin-right:0in;margin-bottom:0in;margin-left:0in;
134
margin-bottom:.0001pt;text-align:justify'>GEOTRANS can also be used to efficiently
135
convert large numbers of coordinates contained in text files. The file format
136
is very simple. A <span class=SpellE>multiline</span> file header defines the
137
coordinate reference frame and datum of the coordinates contained in the file,
138
including any associated parameter values. Following the header, each line
139
contains a single set of coordinates, separated by commas followed by at least
140
one space. Using the GEOTRANS file processing interface, you can select an
141
existing file of coordinates to be converted. You can then define the
142
coordinate reference frame and datum to which you want to convert the
143
coordinates, along with any associated parameter values. Finally, you can
144
specify the name and location of the output file that is to be created.
145
GEOTRANS then converts all of the coordinates in the input file and creates the
146
output file as a single operation.</p>
