Just a quick note:

The take the abs value of the difference between the 2 numbers, check if that is greater than .01. That should read cleaner and get rid of most of those checks.

Also as a favor for the people trying to read your code - pick a style of indenting.

#untested
for ($n=0;$n<=$#lat;$n++) {
    for ($v=0;$v<=$#lat;$v++) {
        if ( abs( $lat[$n] - $lat[$v] ) < .01 and abs( $long[$n] -  $l
+ong[$v] ) < .01 )  {
            ##OTHER CODE   
        }
    }
}

Are you posting in the right place? Check out Where do I post X? to know for sure.
Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
Want more info? How to link or How to display code and escape characters are good places to start.
