<body class='hmmessage'><div dir='ltr'>Hi Steve,<br><br>the new NodDisplay tool reports a lot of errors for files<br>that were created with latest mkgmap .<br>I see lost sync messages as well as things like<br>" error INVALID node, low=0, tabpos=83f, max=30bf"<br><br>Similar problems with my Garmin img file.<br><br>Gerd<br><br><div>> Date: Tue, 14 Jan 2014 14:23:51 +0000<br>> From: steve@parabola.me.uk<br>> To: mkgmap-dev@lists.mkgmap.org.uk<br>> Subject: [mkgmap-dev] Routing<br>> <br>> Hi<br>> <br>> I've been looking into routing and I have updated NodDisplay<br>> so that it mostly works on any file.<br>> I've not discovered much that wasn't known before, apart from<br>> a compact way of storing directions that is probably suitable<br>> for short roads. There is a destination road-class field in<br>> the node flags that we do not seem to set, so we should fix that.<br>> <br>> I am in the process of updating the nod.txt file with everything I've<br>> learned so far.<br>> <br>> There are also two new programs.<br>> <br>> 1. test.check.NodCheck reads in a NOD file and cross checks<br>> various things. So it can tell you if the angle in NOD is similar<br>> to the actual angles between two nodes. Files give lots of errors,<br>> but it doesn't mean that they are wrong, just things to look into.<br>> <br>> 2. test.svg.Main Converts the routing graph to an SVG file that<br>> can be displayed in inkscape (and perhaps other SVG viewers).<br>> The idea is to be able to visualise what is going on. Only a<br>> portion of the file is processed, since the output is very<br>> large.<br>> <br>> They are only of use if you want to look into the routing code. The<br>> output will make no sense at all if you are not familiar with it,<br>> and possibly even if you are ;)<br>> <br>> ..Steve<br>> _______________________________________________<br>> mkgmap-dev mailing list<br>> mkgmap-dev@lists.mkgmap.org.uk<br>> http://www.mkgmap.org.uk/mailman/listinfo/mkgmap-dev<br></div> </div></body>
