Managing multiple map levels

From MSM_Wiki
Jump to: navigation, search

The most basic map has 2 levels of which there is only one working level (the top level has to be left blank). All objects within this map will be displayed at any zoom level.

If your map is getting increasingly crammed due to increase in POIs and roads, you may consider adding addition zoom levels to filter certain POIs or roads from display at high zoom.

Malsing maps have 4 active levels to control the display of polylines and polygons. The 3 images below illustrates the control of road and other object display at different zoom levels:

Adding Zoom Levels[edit]

  1. Click the Map Properties button
  2. Click the Levels tab
  3. There should be at least two levels i.e. Level0 and Level1
  4. To add another level, click and select Level1 then click Insert Before
  5. A new level has been added. Select the new level and click Change to change its zoom properties

Extending Objects to Zoom Levels[edit]

Any new level you created will remain empty of objects until you "extend" objects from Level0 to the new level

  1. Click the Select Objects button
  2. Double-click any object to bring out its properties dialog
  3. Click the Elements tab
  4. Fill the All elements are extended up to level box appropriately
  5. Another method is to right-click the object then select Modify->Extend all elements up to level


  • When you have multiple levels, objects are create at the level you are current zoomed to. For example, if you zoom GPSMapedit up to level 1, any object you create will exist in Level 1 and above, not level 0.
  • If you are making a routable map, all roads MUST be defined in level 0.
  • Be very careful when you delete Level 0. All objects in Level 0 will be deleted as well!
