## 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.

## Claims

### Claim 1

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.

### Claim 2 (depends on 1)

The method of claim 1, wherein the attribute is a display priority.

### Claim 3 (depends on 1)

The method of claim 1, wherein the objects comprise at least an anchor object and at least a data object; the target objects comprise the anchor object and the data object; and the step of controlling the display order with respect to the target objects comprises:
displaying the anchor object before displaying the data object.

### Claim 4 (depends on 3)

The method of claim 3, wherein the objects comprise a plurality of anchor objects and the data object; the target objects comprise the anchor objects and the data object; and the step of controlling the display order with respect to the target objects further comprises:
displaying the anchor objects before displaying the data object.

### Claim 5 (depends on 4)

The method of claim 4, wherein the step of displaying the anchor objects comprises:
controlling a display order with respect to the anchor objects according to a plurality of attributes respectively corresponding to the anchor objects.

### Claim 6 (depends on 3)

The method of claim 3, wherein the objects comprise the anchor object and a plurality of data objects; the target objects comprise the anchor object and the data objects; and the step of controlling the display order with respect to the target objects further comprises:
displaying the anchor object before displaying the data objects.

### Claim 7 (depends on 6)

The method of claim 6, wherein the step of displaying the data objects comprises:
controlling a display order with respect to the data objects according to a plurality of attributes respectively corresponding to the data objects.

### Claim 8 (depends on 1)

The method of claim 1, wherein the step of controlling the display time of the display range to be longer than or equal to the predetermined time comprises:
ignoring any received update instruction for the display range before the display time of the display range reaches the predetermined time.

### Claim 9 (depends on 1)

The method of claim 1, wherein the step of controlling the display time of the display range to be longer than or equal to the predetermined time comprises:
determining a boundary corresponding to the display range according to the predetermined time;
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.

### Claim 10

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:
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.

### Claim 11

An electronic map display system, comprising:
a storage device, for providing an electronic map file including a plurality of objects, each having an attribute; and
a processing device, coupled to the storage device, for 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 processing device controls a display time of the display range to be longer than or equal to a predetermined time for displaying the target objects.

### Claim 12 (depends on 11)

The electronic map display system of claim 11, wherein the attribute is a display priority.

### Claim 13 (depends on 11)

The electronic map display system of claim 11, wherein the objects comprise at least an anchor object and at least a data object; the target objects comprise the anchor object and the data object; and the processing device displays the anchor object before displaying the data object.

### Claim 14 (depends on 13)

The electronic map display system of claim 13, wherein the objects comprise a plurality of anchor objects and the data object; the target objects comprise the anchor objects and the data object; and the processing device displays the anchor objects before displaying the data object.

### Claim 15 (depends on 14)

The electronic map display system of claim 14, wherein the processing device controls a display order with respect to the anchor objects according to a plurality of attributes respectively corresponding to the anchor objects.

### Claim 16 (depends on 13)

The electronic map display system of claim 13, wherein the objects comprise the anchor object and a plurality of data objects; the target objects comprise the anchor object and the data objects; and the processing device displays the anchor object before displaying the data objects.

### Claim 17 (depends on 16)

The electronic map display system of claim 16, wherein the processing device controls a display order with respect to the data objects to display the data objects according to a plurality of attributes corresponding to the data objects.

### Claim 18 (depends on 11)

The electronic map display system of claim 11, wherein the processing device ignores any received update instruction for the display range before the display time of the display range reaches the predetermined time.

### Claim 19 (depends on 11)

The electronic map display system of claim 11, wherein the processing device comprises:
a decision unit, for determining a boundary corresponding to the display range according to the predetermined time; and
a detection unit, coupled to the decision unit, for detecting whether the display range exceeds the boundary; wherein the processing device ignores any received update instruction for the display range before the display range exceeds the boundary.

### Claim 20

An electronic map display system, comprising:
a storage device, for providing an electronic map file including a plurality of objects, each having an attribute; and
a processing device, coupled to the storage device, for 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 processing device comprises:
a decision unit, for setting a boundary corresponding to the display range; and
a detection unit, coupled to the decision unit, for detecting whether the display range exceeds the boundary; wherein the processing device ignores any received update instruction for the display range before the display range exceeds the boundary.
