Solution

  • Following my comment, you can use this html page to generate as many points as you want.

    <!DOCTYPE html>
<html lang="en-au">
<head>
    <meta charset="utf-8">
    <meta http-equiv="pragma" content="no-cache" />
</head>
<body>
<script type="text/javascript">
function generatePoints(){
    var pointsToGenerate = document.getElementById('pointsToGenerate').value;

    var output = '';

    for (i=0;i<pointsToGenerate;i++) {
        var multiplier = 10000;
        var latitude=(Math.random()*(90*multiplier))/multiplier;
        var longitude=(Math.random()*(180*multiplier))/multiplier;
        latitude *=(Math.floor(Math.random()*2) == 1)?1:-1;
        longitude *=(Math.floor(Math.random()*2) == 1)?1:-1;
        output = output + latitude + ',' + longitude + '\n';
    }

    document.getElementById('output').innerHTML = output;
}
</script>
<input type="text" id="pointsToGenerate" value="1000" />
<input type="button" onclick="generatePoints()" value="Generate Points" />
<div><textarea cols=40 rows=10 id="output"></textarea></div>
</body>
</html>
