Problems trying to generate contour lines for France
Hi, I have generated 160 .osm files with srtm2osm to generate a garmin elevation map for France. When trying to run mkgmap-r844 on the folder containing the files, I got a problem : Exception in thread "main" java.lang.NullPointerException at sun.misc.FloatingDecimal.readJavaFormatString(FloatingDecimal.java:991) at java.lang.Double.parseDouble(Double.java:510) at uk.me.parabola.mkgmap.reader.osm.xml.Osm5XmlHandler.addNode(Osm5XmlHandler.java:316) at uk.me.parabola.mkgmap.reader.osm.xml.Osm5XmlHandler.startElement(Osm5XmlHandler.java:102) at com.sun.org.apache.xerces.internal.parsers.AbstractSAXParser.startElement(AbstractSAXParser.java:501) at com.sun.org.apache.xerces.internal.parsers.AbstractXMLDocumentParser.emptyElement(AbstractXMLDocumentParser.java:179) at com.sun.org.apache.xerces.internal.impl.XMLDocumentFragmentScannerImpl.scanStartElement(XMLDocumentFragmentScannerImpl.java:1339) at com.sun.org.apache.xerces.internal.impl.XMLDocumentFragmentScannerImpl$FragmentContentDriver.next(XMLDocumentFragmentScannerImpl.java:2747) at com.sun.org.apache.xerces.internal.impl.XMLDocumentScannerImpl.next(XMLDocumentScannerImpl.java:648) at com.sun.org.apache.xerces.internal.impl.XMLDocumentFragmentScannerImpl.scanDocument(XMLDocumentFragmentScannerImpl.java:510) at com.sun.org.apache.xerces.internal.parsers.XML11Configuration.parse(XML11Configuration.java:807) at com.sun.org.apache.xerces.internal.parsers.XML11Configuration.parse(XML11Configuration.java:737) at com.sun.org.apache.xerces.internal.parsers.XMLParser.parse(XMLParser.java:107) at com.sun.org.apache.xerces.internal.parsers.AbstractSAXParser.parse(AbstractSAXParser.java:1205) at com.sun.org.apache.xerces.internal.jaxp.SAXParserImpl$JAXPSAXParser.parse(SAXParserImpl.java:522) at javax.xml.parsers.SAXParser.parse(SAXParser.java:395) at javax.xml.parsers.SAXParser.parse(SAXParser.java:198) at uk.me.parabola.mkgmap.reader.osm.xml.Osm5MapDataSource.load(Osm5MapDataSource.java:78) at uk.me.parabola.mkgmap.main.MapMaker.loadFromFile(MapMaker.java:124) at uk.me.parabola.mkgmap.main.MapMaker.makeMap(MapMaker.java:43) at uk.me.parabola.mkgmap.main.Main.processFilename(Main.java:150) at uk.me.parabola.mkgmap.CommandArgs$Filename.processArg(CommandArgs.java:329) at uk.me.parabola.mkgmap.CommandArgs.readArgs(CommandArgs.java:119) at uk.me.parabola.mkgmap.main.Main.main(Main.java:91) Am I doing something wrong ? Thanks Frédéric

It looks like the .osm-file is malformed, or at least not in the format mkgmap expects: This is mkgmap trying to parse the latitude and longitude of a node as floating point numbers and failing. Perhaps they're in a different format or missing? Cheers Robert

This happens because srtm2osm sometimes misses out the longitude coordinate. At least an earlier version did that, when I tried recently with the latest version I didn't get any problems but I may have just been lucky. I can anyway fix mkgmap so that it ignores points that don't have both a latitude and longitude. Regards ..Steve
