Not my work.. See the info in the script. I just made some minor changes and bugfixes so far.
The polygons aren't that hard to figure out.
Collate the gps-point data for each BSSID, and use them to make the boundaries of the polygon.
Code:
/*******************
* parse .gps file and build gps coordinates index
********************/
foreach($gps->{'gps-point'} as $value)
{
$coordinates[(string) $value['bssid']][] = array((string) $value['lon'], (string) $value['lat']);
}
Then make the polygon :
Code:
/*******************
* assemble polygon placemark
********************/
if($network['channel'] != '0') //we don't display networks with no height
{
$poly .= "<Placemark>\n<name><![CDATA[";
if(empty($network['SSID'])) $poly .= "no ssid";
else $poly .= $network['SSID'];
echo "SSID:".$network['SSID']." BSSID:".$network['BSSID']."\n";
$poly .= "]]></name>\n<visibility>0</visibility>\n<open>0</open>\n";
$poly .= "<Style>\n\t<LineStyle>\n\t<width>1.5</width></LineStyle>\n\t<PolyStyle>";
if($xml->{'wireless-network'}[$key]['wep'] == 'true') //set color
$poly .= "<color>8f00ff00</color>\n"; //green, closed
elseif($meta[$key]['cloaked'] == 'true')
$poly .= "<color>7dff0000</color>\n"; //blue, cloaked
else
$poly .= "<color>7d00ff00</color>\n"; //red, open
$poly .= "</PolyStyle>\n</Style>\n<Polygon>\n<extrude>1</extrude>\n<tessellate>0</tessellate>\n";
$poly .= "<altitudeMode>relativeToGround</altitudeMode>\n<outerBoundaryIs>\n<LinearRing>\n<extrude>0</extrude>";
$poly .= "<tessellate>0</tessellate>\n<altitudeMode>clampToGround</altitudeMode>\n<coordinates>";
$poly_alt = $network['channel']*10;
foreach($coordinates[$network['BSSID']] as $index => $gpoints)
{
if($gpoints[0] != $coordinates[$network['BSSID']][$index-1][0]
&& $gpoints[1] != $coordinates[$network['BSSID']][$index-1][1]) //remove duplicates
$poly .= $gpoints[0].", ".$gpoints[1].", ".$poly_alt." ";
}
$poly .= $coordinates[$network['BSSID']][0][0].", ".$coordinates[$network['BSSID']][0][1].", ".$poly_alt." "; //finish polygon at first coordinate
$poly .= "</coordinates>\n</LinearRing>\n</outerBoundaryIs>\n</Polygon>\n</Placemark>";
}
} //end foreach
and finally output it to the kml file
Code:
//output 3D visualized polygons
$kml_final .= "<Folder>\n<name>3D visualized view</name><open>0</open>\n";
$kml_final .= $poly;
$kml_final .= "</Folder>\n";
Converting the above snippets of code to the language of your choice shouldn't be to hard, albeit I'm not so sure dBase 7.5 has the constructs for easy looping and temporary arrays.
