Embodiment Construction

[0047] In order to enable those skilled in the art to better understand the technical solutions in this specification, the technical solutions in the embodiments of this specification will be clearly and completely described below in conjunction with the drawings in the embodiments of this specification. Obviously, the described The embodiments are only some of the embodiments in this specification, not all of them. Based on the embodiments in this specification, all other embodiments obtained by persons of ordinary skill in the art without creative efforts shall fall within the protection scope of this specification.

[0048] With the development of computer network technology, people can learn about geographical locations and other information around the world through electronic maps. Usually maps or electronic maps are divided into regions by provinces and countries. However, in some cases, it may be necessary to merge some designated areas on the map, such as: merge the th...

Abstract

The present specification provides a data processing method and device for map region merging. The method comprises the following steps of: drawing a map image of an area to be merged by using a linewith preset transparency to generate an initial merged map image; acquiring transparency of pixel points in the initial merged map image; and taking a pixel point whose transparency be the same as thepreset transparency as a target pixel point, and generating a merged target merged map image according to the target pixel point. The data processing method and device for map region merging can realize flexible merging of map regions. The method is simple and fast, does not need complex data processing, and can accurately detect the overlapping part of the boundary, so that the merging of map regions is more accurate and fast, and the merged map regions can be used as a whole for interaction, convenient for subsequent use, and wide applicability.

Description

technical field [0001] This specification belongs to the technical field of map data processing, and in particular relates to a data processing method and device for merging map regions. Background technique [0002] With the development of computer technology, the appearance of electronic map has brought great convenience to people's life. When using electronic maps, we often encounter the need to merge multiple areas in the map into one area, for example: merge the three northeastern provinces into the Greater Northeast Region, merge Zhejiang, Shanghai, and Suzhou into the East China Region, and merge many countries into Middle East etc. [0003] In the prior art, when merging regions in a map, it is usually possible to use mathematics to calculate coincident lines between multiple regions, but the data processing process is complicated, not flexible enough, and poor in applicability. Therefore, there is an urgent need for a convenient and quick implementation of map are...
