Electronic map interest point marking method, system and equipment

Abstract

The invention suitable for the electronic map field provides a method for marking an electronic map interest point, a system and a device; the method comprises the following steps that: an interest point with a sign region in a display window is selected; the interest point is carried out by simulation marking in the simulated display window; a simulated marker of the interest point in the simulated display window is detected; a simulated marking region of an unmarked interest point is selected; the unmarked interest point is marked in the region of the display window corresponding to the simulated marking region. The method for marking an electronic map interest point, a system and a device can optimize and arrange the marking region of the interest point on the whole, can avoid the marking of the interest point being cut by window boundary and remove the phenomena of superposition and occupancy between the markers of the interest points or between the marker and the sign of the interest point in order that more interest points can obtain markers.

Description

technical field [0001] The invention belongs to the field of electronic maps, and in particular relates to a method, system and equipment for annotating points of interest in an electronic map. Background technique [0002] The processing of interest points in the electronic map includes the search, display and annotation of interest points. At present, POIs are generally annotated with fixed positions and adjustments. Only adjust if the POI's annotation is clipped by the display window boundaries, if the POI's annotation overlaps with other POI's symbols, or if it overlaps with the POI's annotation. When adjusting, the 8 possible annotation positions around the point of interest are cycled, and the position where the above situation does not occur is selected according to the level for annotation. This annotation method will produce preemptive annotation. For example, POI A has positions 4 and 8 to annotate, POI B only has position 1 to annotate, and POI A’s position 4 ov...

Problems solved by technology

[0004] The purpose of the embodiment of the present invention is to provide a method for annotating points of interest on electronic maps, which aims to solve the problem of using existing point-of-interest annotation schemes when the points of interest are dense or the annotations of points of interest are displayed in the window due to the roaming movement of the electronic map. When the border is clipped, the annotations of the points of interest will be crowded, resulting in the problem that many points of interest that can be annotated cannot be annotated
