Information

Hvis du foretrækker at se en video frem for at læse instruktioner, så klik her for at se vores vejledningsvideo. Anden halvdel forklarer offline rutevejledning (med tysk tale).

Kom i gang

Igennem hele denne vejledning antager jeg, at du har en Nokia N900 med Marble og Monav installeret. Du kan finde instruktioner i, hvordan man installerer softvare i vores installationsvejledning.

Under opsætning af offline rutevejledningen skal du også bruge internetadgang. Når data for det område, som du er interesseret i er downloadet, så behøver du ikke internetadgangen længere. Herefter kan du bruge Marble til at beregne ruter i den region uden internetadgang.

Start Marble på N900. Skærmen vil se nogenlunde sådan ud, bortset fra, at det nok er et andet sted, der vises på kortet.

Vi vil bruge Schweiz i dette eksempel. Lad os antage, at vi er i Bern, hovedstaden i Schweiz, og vil bruge Marble til offline rutevejledning.

Installation af kort til rutevejledning

For at få offline rutevejledning til at virke skal vi først downloade et passende kort til offline rutevejledning. Marble kan downloade kort til ruteplanlægning for bilkørsel. Der findes kort over alle verdens lande, som kan downloades. For nogle lande kan man også installere kort over mindre dele af landet.

Nu vil vi downloade kortet over Schweiz. For at gøre dette åbner du Marbles programmenu: Tap på teksten Marble - virtuel globus øverst på skærmen. Vælg knappen Ruteplanlægning nederst til venstre.

Nu åbnes ruteplanlægningsdialogen. Det er blot en mellemstation; gå direkte til linket Indstil.

Et klik på linket Indstil åbner en dialog, hvor du kan indstille den aktuelle rutevejledningsprofil.

Her deaktiverer vi alle Aktive rutetjenester (de tjenester og programmer, som Marble bruger til at finde ruter) undtagen Monav, den offline rutevejleder, som vi vil bruge. Når kun Monav er valgt som vist i skærmbilledet herover, så tap på knappen Indstil. I den dialog, som dukker frem går du til fanebladet Installer nyt og vælg Schweiz.

Note

Marble skal bruge en internetforbindelse for at kunne vise, hvilke offlinekort, der er til rådighed. Tjek din internetforbindelse, hvis dialogens felter forbliver tomme.

Klar? Så tap Installér for at få Marble til at downloade kortet. Du ser en fremgangsindikator imens kortet bliver downloadet.

Vent, imens kortet bliver downloadet og installeret. Når det er overstået, så vises det nye kort i begge fanebladene Indstil og Håndtér kort.

Tip

Du kan vende tilbage til denne dialog en gang imellem for at opdatere de installerede kort.

With the Switzerland map successfully installed, we can continue to use it for offline routing. Hit Done in all opened dialogs to close them.

Downloading Map Data

Marble is able to calculate routes anywhere within Switzerland now. The map images that are displayed are not available yet however -- if you'd cut the Internet connection now and move the map to a part of Switzerland you didn't look up before, Marble would not have a detailed map image to show to you. Fortunately there's the Download Region feature to help out. It downloads the map images (which are often called tiles) for a rectangular region -- the part you see on the screen -- or along the current route.

Let's see the Download Region feature in action. We'll calculate a route and download tiles along it. Move the map near the desired start, click on the start point and select Directions from here in the upcoming menu.

Likewise, select the route destination using the Directions to here menu entry. Marble will calculate the route and show it to you.

To download the tiles along the route, make sure Marble is not in offline mode. If the main menu looks like in the next screenshot with the Work Offline button enabled, click on it to disable the offline mode.

Afterwards, choose Download Region... from the main menu to open the Download Region dialog. Choose the Download Route option. Marble will determine which parts of the map the route touches and download the corresponding tiles. You can also select a margin laterally to the route where tiles are downloaded as well. Increasing the margin allows you to deviate further from the planned route, but also increases the download size.

In the bottom part of the same dialog you can select which zoom levels (tile levels) to download. We'll increase the maximum zoom level to 18 to get the most detailed maps for this short route. Note how increasing the maximum tile level also increases the number of tiles to download and the estimated size of the download.

Hit Done to have Marble download the tiles. The dialog closes and the download progress is shown in the little pie chart on the right side of the map.

Note

Marble can only download tiles if an Internet connection is available and Marble's offline mode is not activated.

Once the download is finished, you're all prepared for offline mode. Click on the Guidance Mode button (the left of the four large buttons on the bottom of the screen) to have Marble follow you on the route, highlight driving instructions at turn points and re-calculate the route in case you deviate from it. Further details on this topic are described in the Guidance Mode page.
