19 * \brief Conversion between geographic coordinates
20 *
21 * This class stores a geographic position which may be set via the
22 * constructors or Reset via
23 * - latitude and longitude
24 * - UTM or UPS coordinates
25 * - a string representation of these or an MGRS coordinate string
26 *
27 * The state consists of the latitude and longitude and the supplied UTM or
28 * UPS coordinates (possibly derived from the MGRS coordinates). If latitude
29 * and longitude were given then the UTM/UPS coordinates follows the standard
30 * conventions.
31 *
32 * The mutable state consists of the UTM or UPS coordinates for a alternate
33 * zone. A method SetAltZone is provided to set the alternate UPS/UTM zone.
34 *
35 * Methods are provided to return the geographic coordinates, the input UTM
36 * or UPS coordinates (and associated meridian convergence and scale), or
37 * alternate UTM or UPS coordinates (and their associated meridian
38 * convergence and scale).
39 *
40 * Once the input string has been parsed, you can print the result out in any
41 * of the formats, decimal degrees, degrees minutes seconds, MGRS, UTM/UPS.
42 *
43 * Example of use:
44 * \include example-GeoCoords.cpp
45 *
46 * <a href="GeoConvert.1.html">GeoConvert</a> is a command-line utility
47 * providing access to the functionality of GeoCoords.

106 * The following inputs are approximately the same (Ar Ramadi Bridge, Iraq)
107 * - Latitude and Longitude

109 * - N33d26.4' E43d16.2'
110 * - 43d16'12&quot;E 33d26'24&quot;N

121 * <b>Latitude and Longitude parsing</b>: Latitude precedes longitude,
122 * unless a N, S, E, W hemisphere designator is used on one or both
123 * coordinates. If \e longfirst = true (default is false), then
124 * longitude precedes latitude in the absence of a hemisphere designator.
125 * Thus (with \e longfirst = false)
126 * - 40 -75
127 * - N40 W75
128 * - -75 N40
129 * - 75W 40N
130 * - E-75 -40S
131 * .
132 * are all the same position. The coordinates may be given in
133 * decimal degrees, degrees and decimal minutes, degrees, minutes,
134 * seconds, etc. Use d, ', and &quot; to mark off the degrees,
135 * minutes and seconds. Various alternative symbols for degrees, minutes,
136 * and seconds are allowed. Alternatively, use : to separate these
137 * components. A single addition or subtraction is allowed. (See
138 * DMS::Decode for details.) Thus
139 * - 40d30'30&quot;
140 * - 40d30'30
141 * - 40&deg;30'30
142 * - 40d30.5'
143 * - 40d30.5
144 * - 40:30:30
145 * - 40:30.5
146 * - 40.508333333
147 * - 40:30+0:0:30
148 * - 40:31-0:0.5
149 * .
150 * all specify the same angle. The leading sign applies to the following
151 * components so -1d30 is -(1+30/60) = &minus;1.5. However, note
152 * that -1:30-0:0:15 is parsed as (-1:30) + (-0:0:15) = &minus;(1+30/60)
153 * &minus; (15/3600). Latitudes must be in the range [&minus;90&deg;,
154 * 90&deg;]. Internally longitudes are reduced to the range
155 * [&minus;180&deg;, 180&deg;].
156 *
157 * <b>UTM/UPS parsing</b>: For UTM zones (&minus;80&deg; &le; Lat <
158 * 84&deg;), the zone designator is made up of a zone number (for 1 to 60)
159 * and a hemisphere letter (n or s), e.g., 38n (38north can also be used).
160 * The latitude band designer ([C--M] in the southern hemisphere and [N--X]
161 * in the northern) should NOT be used. (This is part of the MGRS
162 * coordinate.) The zone designator for the poles (where UPS is employed)
163 * is a hemisphere letter by itself, i.e., n or s (north or south can also
164 * be used).
165 *
166 * <b>MGRS parsing</b> interprets the grid references as square area at the
167 * specified precision (1m, 10m, 100m, etc.). If \e centerp = true (the
168 * default), the center of this square is then taken to be the precise
169 * position; thus:
170 * - 38SMB = 38n 450000 3650000
171 * - 38SMB4484 = 38n 444500 3684500
172 * - 38SMB44148470 = 38n 444145 3684705
173 * .
174 * Otherwise, the "south-west" corner of the square is used, i.e.,
175 * - 38SMB = 38n 400000 3600000
176 * - 38SMB4484 = 38n 444000 3684000
