Frank Stinner tries to find a solution for this :-)<br> -- Problems with java heap when creating large or highly detailed maps:<br> Zipped files require more heap memory because the current implementation has to keep a copy of the unzipped content while unzipped files<br> are kept in MappedByteBuffers which don't require java heap. On the other hand they maybe cause other problems as those reported by Carlos:<br> <a href="http://gis.19327.n8.nabble.com/mkgmap-r4025-implements-x-dem-poly-option-tp5909038p5909257.html">http://gis.19327.n8.nabble.com/mkgmap-r4025-implements-x-dem-poly-option-tp5909038p5909257.html</a><br> One work around would be to keep the unzipped data in temporary files (more I/O), another solution might be to further change the algorithm<br> so that it doesn't require full random access to all(!) hgt files "touched" by the overview map. I've already tried to change that with r4027<br> so that only some rows are required, but that code is not very elegant. I hope I find a better solution for this. <br> @Frank: I think BuildDEMFile also has this problem, right?<br> -- The code needs further clean up , javadoc and unit tests. <br> <br> Thanks for the good feedback so far, I think this will be another big improvement if merged into trunk.<br> <br> Gerd<br> _______________________________________________<br> mkgmap-dev mailing list<br> mkgmap-dev@lists.mkgmap.org.uk<br> <a href="http://www.mkgmap.org.uk/mailman/listinfo/mkgmap-dev">http://www.mkgmap.org.uk/mailman/listinfo/mkgmap-dev</a><br></div></div></blockquote><p class="default-style"><br> </p><blockquote type="cite">_______________________________________________<br>mkgmap-dev mailing list<br>mkgmap-dev@lists.mkgmap.org.uk<br>http://www.mkgmap.org.uk/mailman/listinfo/mkgmap-dev</blockquote></body></html>
