Abstract
An electronic map display method is disclosed. The method includes: providing an electronic map file having a plurality of objects where each object has an attribute; and comparing a plurality of attributes corresponding to a plurality of target objects included within a display range to control a display order with respect to the target objects for displaying the target objects.
Claims20
An electronic map display method, comprising:
- providing an electronic map file including a plurality of objects, each object having an attribute;
- and
- comparing a plurality of attributes corresponding to a plurality of target objects included within a display range to control a display order with respect to the target objects for displaying the target objects, wherein the step of displaying the target objects comprises:
- controlling a display time of the display range to be longer than or equal to a predetermined time.

- providing an electronic map file including a plurality of objects, each object having an attribute;
- and
- comparing a plurality of attributes corresponding to a plurality of target objects included within a display range to control a display order with respect to the target objects for displaying the target objects, wherein the step of displaying the target objects comprises:
- setting a boundary corresponding to the display range;
- detecting whether the display range exceeds the boundary;
- and
- ignoring any received update instruction for the display range before the display range exceeds the boundary.
