141 .SH "NAME"
142 Geo::Hashing \- Perl library to calculate Geohashing points
143 .SH "SYNOPSIS"
145 .Vb 3
146 \& use Geo::Hashing;
147 \& my \$g = new Geo::Hashing(lat => 37, lon => \-122, date => "2008\-05\-24");
148 \& printf "Today\*(Aqs location is at %.6f, %.6f.\en", \$g\->lat, \$g\->lon;
149 .Ve
150 .SH "DESCRIPTION"
152 This module allows calculating the locaiton of Geohashes as described
153 in http://wiki.xkcd.com/geohashing/Main_Page.
154 .SH "METHODS"
156 .SS "new"
157 .IX Subsection "new"
158 Create a new Geo::Hashing object.
159 .SS "lat"
160 .IX Subsection "lat"
161 Set or get the points latitude. When settings, only the integer portion is
162 considered. Set to undef to just get the offset.
163 .SS "lon"
164 .IX Subsection "lon"
165 Set or get the points longitude. When settings, only the integer portion is
166 considered. Set to undef to just get the offset.
167 .SS "date"
168 .IX Subsection "date"
169 Set or get the date used for the calculation. Note that this is the actual
170 date of the meetup in question, even when the 30w rule is in effect.
171 .SS "djia"
172 .IX Subsection "djia"
173 Set or get the Dow Jones Industrial Average used for the calculation. If not
174 set, it will be automatically retrieved depending on the value of
175 \&\f(CW\$self\fR\->source. If the data cannot be retrieved, undef will be returned.
176 .SS "source"
177 .IX Subsection "source"
178 Set the source of the \s-1DJIA\s0 opening data. Will load Geo::Hashing::Source::Name
179 and call get_djia(\$date). See Geo::Hashing::Source::Random for a sample.
180 .SS "use_30w_rule"
181 .IX Subsection "use_30w_rule"
182 Set or get the 30w flag. Will be set automatically if lon is set and is
183 greater than \-30.
184 .SS "debug"
185 .IX Subsection "debug"
186 Enable or disable diagnostic logging
