<span><span>Dear all.<br>
</span>
<div>​</div>
<div>I'm coding Java MapScript program as servlet webapp of Tomcat (on Windows), using "javamapscript.dll" and "mapscript.jar", to process "mapObj" object dyamically.​</div>
<div>​</div>
<div>I have some problems on contour rendering.​</div>
<div>Could someone please tell me how to fix them?​</div>
<div>​</div>
<div>I request multiple tiled (client-side tiling) GetMap operations, and get images.​</div>
<div>​</div>
<div>Problem 1:​</div>
<div> Some contours can break off on tile edge (not allways).​</div>
<div> The simple geometric data (vector, raster) does not break off on tile edge.​</div>

<div>​</div>
<div>Problem 2:​</div>
<div> I create TILEINDEX shapefile with gdaltindex command (on QGIS or on CUI) specifying one or multiple DEM files.​</div>
<div> For only 1 DEM file, the contours are shown.​</div>
<div> But, for multiple DEM files, contours only for one of them are shown.​</div>
<div> 2 DEMs, 10 DEMs, 100 DEMs, in the same way.​</div>
