[Tilecache] Re: tilecache problem with LABELMAXSCALEDENOM

[mojtabajml]

I write a php function for compute:

<?php
function get_resolutions($scales, $units)
{
    $dpi = 72.0;
    $factor = array('inches'=> 1.0, 'ft'=> 12.0, 'mi'=> 63360.0, 'm'=>
39.3701,'km'=> 39370.1, 'dd'=> 4374754.0);
   
    $inches = 1 / $dpi;
    $monitor_l = $inches / $factor[$units];
   
    $resolutions = '';
	foreach($scales as $scale)
	{
		$real_l = $monitor_l * intval($scale);
		$resolutions .= sprintf( '%.17f , ' , $real_l );
	}
    return $resolutions ;
}
$scales = array(2000,1900,1800,1700,1600,1500,1400,130,1200,1100
				,1000,900,800,700,600,500,400,300,200,100);
echo get_resolutions($scales,'m');
?>
/////////////////
the output is:
0.70555517455576122 , 0.67027741582797318 , 0.63499965710018502 ,

in Mapfile I modify RESOLUTION to 0.70555517455576122 and in openlayers and
tilecache.cfg set maxResolution=0.70555517455576122

but I have yhis error:
An error occurred: can't find resolution index for 0.035278. Available
