<pre class="blue">I have a problem and no idea how to solve it...<br><br>So, for everyone knowing general aviation, I'm trying to define the <br>GAFOR-Routes of Austria and Switzerland.<br> From the internet site of Austrocontrol (general aviation portal for <br>Austria) I have a detailled description for these routes, but only "for <br>human beings"...<br>Something like:<br><br>10 LOWI - Mieminger Plateau - Fernpass - Reutte - Pfronten - EDMK 4700<br>11 LOWI - Inntal - Landeck - Arlberg - Feldkirch - LOIH 7000<br>12 LOWI - Autobahn A12 - LOIK 2600<br><br>and so on...<br>LOWI, EDMK, LOIH, LOIK are airfield (ICAO codes). Of course I have the <br>coordinates of these airfield.<br>And I have the coordinates of the cities, too.<br>I think, in OpenStreetMaps I can get the coordinates of other points <br>(eg.: Mieminger Plateau).<br><br>So, now the problem: I need to create a "corridor" over these regions. <br>Then I have to export the coordinates as GeoJSON to display the <br>corridors with Leaflet.<br><br>And, as I sayd, I have no idea how to start solving my problem... ;)<br><br>Thank you very much for your help!<br>Luca Bertoncello<br>(lucabert@lucabert.de)<br></pre></blockquote></div></body></html>
