Dear Userlist,<br><br>I'm running TileCache with Openlayers and Mapserver (under CGI) - my Openlayers .php file is working fine until the fourth zoom level - only some parts of the map are shown and on the corners and borders the images aren't drawn - only my Overview map (with the same values like the map has) is able to show this content - I guess this is due to wrong resolutions but I don't know where my mistake is - it would be nice if someone could help me finding the error.<br>
<br><br>Here are my map options defined in the Openlayers .php file :<br>--------------------------------------------------------------------------------------------------------------<br><br> var mapOptions = { projection: "EPSG:4326",
<br> controls: [], <br> scales: [17500000, 14000000, 7000000, 3000000, 2000000, 1000000, 400000, 250000],<br> maxResolution: "auto",
<br> maxExtent: new OpenLayers.Bounds(60.00167, 20, 100, 44.984),
<br> restrictedExtent: new OpenLayers.Bounds(60.00167, 20, 100, 44.984),
<br> eventListeners: {"moveend": mapEvent }
<br> };<br><br>---------------------------------------------------------------------------------------------------------------<br><br>And this is my TileCache layer defined in tilecache.cfg file:<br>

srs=EPSG:4326<br>extension=png<br>-----------------------------------------------------------------------------------------------------------<br> <br>The first 3 resolution values were - I guess - recommanded by TileCache - the remaining resolution values are calculated with the following function:<br>
<br> for (var i = 0; i <= map.numZoomLevels; i++) {<br> resolutions.push(map.getResolutionForZoom(i));<br> }<br> console.log(resolutions.join(','));<br><br>Thanks in advance for help.<br><br>Martin<br>
