<div dir="ltr">Unfortunately there is no connection to internet on the platform I develop on. All is done localy.<br><br>I will try to be more precise.<br>I am trying to display a shapefile representing the whole world (it's a shapefile from Global Insight plus if it helps). I use mapfish without 'singleTile: true' so the layer is generated by tiles.<br>
<br>There is no problem in the beggining when the map is zoomed to max extent.<br><br>The problem occurs when I begin zooming in and trying to display America/Asia. One of the "colums" of tiles is drawn across the -180°/+180° longitude line, and those tiles are generated entirely blank (white, not even transparent).<br>
<br>When I get the properties of the image (right-click on the blank tile -> Properties) and I search in the "Location" of the image I can find :<br><span style="color: rgb(51, 51, 255);">mapext=179.296875+44.296875+<b>225.703125</b>+90.703125&imgext=179.296875+44.296875+<b>225.703125</b>+90.703125<span style="color: rgb(0, 0, 0);"> <br>
So I guess the problem comes from that, MapServer doesn't recognise longitude greater than 180 or lower than -180.<br>If I'm right I would appreciate any hint on how to handle this...<br><br></span></span>Otherwise it may be a mapfish issue, maybe mapfish should always generate tiles with borders right on -180 / +180. This is the case at the beggining, lef tile has mapext=90+0+180+90 and right tile has mapext=-180+0+-90+90.<br>
But whenever I begin zooming in it goes awry, the border of tiles is no longer right on -180/+180 and some tiles are generated white by MapServer.<br><br>If someone needs more informations I'm ready to give it.<br><br>
