<body class='hmmessage'><div dir='ltr'>Hi Johan,<br><br>v3 and v4 are new style with two different program options,<br>v5 and v6 are slightly modified new style maps with the same options.<br><br>More detailed:<br>If you watch your map, you see that Garmin shows major roads<br>with other colors and bitmaps compared to smaller roads. <br>This is done because the img file contains information about<br>the "type of road". The roundabouts are special, because Garmin<br>only has one type "roundabout", so normally, it displays the roundabout<br>for a major road with the same color and bitmap as one for a small road.<br>The "new style" tried to use a "trick": It stores the roundabout once as<br>roundabout, once as a normal street, so that the device shows the correct<br>color and bitmap, but obviously this confuses the algo in your device.<br>The v5 and v6 versions don't contain this trick.<br><br>AFAIK Garmin maps never use this trick, so I fear we can't blame the Garmin algo<br>for being confused.<br><br>@Minko, Lambertus: <br>I'd prefer the map without the trick, it is smaller and less likely to confuse the routing.<br><br>Gerd<br><br><div><hr id="stopSpelling"><br><div class="ecxWordSection1"><p class="ecxMsoNoSpacing"><span style="font-size:12.0pt;color:#1F497D;" lang="EN-US">We know that Generic Routable (old style) maps compiled by Lambertus’s site work correct.<br>We know that Generic Routable (new style) maps compiled by Lambertus’s site cause problems.<br><br>The test maps you send me… are they all new style maps?</span></p><p class="ecxMsoNoSpacing"><span style="font-size:12.0pt;color:#1F497D;" lang="EN-US"><br></span></p><p class="ecxMsoNoSpacing"><span style="font-size:12.0pt;color:#1F497D;" lang="EN-US"> <br></span></p><p class="ecxMsoNoSpacing"><span style="font-size:12.0pt;color:#1F497D;" lang="EN-US"> </span></p><p class="ecxMsoNoSpacing"><span style="font-size:12.0pt;color:#1F497D;" lang="EN-US"> </span></p><p class="ecxMsoNoSpacing"><span style="font-size:12.0pt;color:#1F497D;" lang="EN-US"><br>Here are the results of the 4 maps samples you sent me:<br>**********************************************<br>v3 – the icon indicating the relative position for exiting the roundabout is INCORRECT</span></p><p class="ecxMsoNoSpacing"><span style="font-size:12.0pt;color:#1F497D;" lang="EN-US">(a relative position indicating one roundabout exit LATER than the correct exit)</span></p><p class="ecxMsoNoSpacing"><span style="font-size:12.0pt;color:#1F497D;" lang="EN-US"> </span></p><p class="ecxMsoNoSpacing"><span style="font-size:12.0pt;color:#1F497D;" lang="EN-US">v4 – the icon indicating the relative position for exiting the roundabout is INCORRECT</span></p><p class="ecxMsoNoSpacing"><span style="font-size:12.0pt;color:#1F497D;" lang="EN-US">(a relative position indicating one roundabout exit LATER than the correct exit)</span></p><p class="ecxMsoNoSpacing"><span style="font-size:12.0pt;color:#1F497D;" lang="EN-US"> </span></p><p class="ecxMsoNoSpacing"><span style="font-size:12.0pt;color:#1F497D;" lang="EN-US">V5 – the icon indicating the relative position for exiting the roundabout is CORRECT<br><br></span></p><p class="ecxMsoNormal"><span style="font-family:"Calibri","sans-serif";color:#1F497D;" lang="EN-US">V6 – the icon indicating the relative position for exiting the roundabout is CORRECT<br><br></span></p><p class="ecxMsoNormal"><span style="font-family:"Calibri","sans-serif";color:#1F497D;" lang="EN-US"> </span></p><p class="ecxMsoNormal"><span style="font-family:"Calibri","sans-serif";color:#1F497D;" lang="EN-US"> </span></p><p class="ecxMsoNormal"><span style="font-family:"Calibri","sans-serif";color:#1F497D;" lang="EN-US"><br>Greetings<br>Johan</span></p><p class="ecxMsoNormal"><span style="font-family:"Calibri","sans-serif";color:#1F497D;" lang="EN-US"> </span></p><p class="ecxMsoNormal"><span style="font-family:"Calibri","sans-serif";color:#1F497D;" lang="EN-US"> </span></p><p class="ecxMsoNormal"><span style="font-family:"Calibri","sans-serif";color:#1F497D;" lang="EN-US"> </span></p><p class="ecxMsoNormal"><span style="font-family:"Calibri","sans-serif";color:#1F497D;" lang="EN-US"> </span></p><p class="ecxMsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D;" lang="EN-US"> </span></p><div><div style="border:none;border-top:solid #B5C4DF 1.0pt;padding:3.0pt 0cm 0cm 0cm;"><p class="ecxMsoNormal"><b><span style="font-size:10.0pt;font-family:"Tahoma","sans-serif";" lang="EN-US">From:</span></b><span style="font-size:10.0pt;font-family:"Tahoma","sans-serif";" lang="EN-US"> mkgmap-dev-bounces@lists.mkgmap.org.uk [mailto:mkgmap-dev-bounces@lists.mkgmap.org.uk] <b>On Behalf Of </b>Gerd Petermann<br><b>Sent:</b> 4. oktober 2014 08:29<br><b>To:</b> mkgmap-dev@lists.mkgmap.org.uk<br><b>Subject:</b> Re: [mkgmap-dev] Incorrect runabout exit indication</span></p></div></div><p class="ecxMsoNormal"> </p><div><p class="ecxMsoNormal"><span style="font-family:"Calibri","sans-serif";">Hi Minko,<br><br>thanks for the info.
