Problems solved by technology

[0004] The current map data update method is generally to import the new map into the system first, then manually match the new map with the old map, and update the old map according to the matching result. This update method is less automated and wastes a lot of human resources.

Abstract

The invention discloses a GIS-based map data updating method and system of an application system. The method comprises the following steps of: importing an object corresponding to a to-be-updated layer in the application system in a new map as a working layer; comparing each object in the working layer with the object in the layer to be updated, determining the matching state attribute of each object in the working layer according to the comparison result, and updating the layer to be updated according to the matching state attribute of each object in the working layer; comparing each object in the layer to be updated with an object in the working layer, and updating the layer to be updated according to a comparison result; and after the layer to be updated is updated, deleting the workinglayer, so that the purposes of automatically comparing the map data in the new map with the map data in the system, adding the objects added in the new map into the system and deleting the objects existing in the system but not existing in the new map can be achieved.

Description

technical field [0001] The present invention relates to the technical field of GIS (Geographic Information Systems, geographic information systems), in particular to a method and system for updating map data of a GIS-based application system. Background technique [0002] GIS (Geography Information System, geographic information system) is based on geospatial database, with the support of computer software and hardware, to collect, input, manage, edit, query, analyze, simulate and display spatial related data, and adopt spatial Model analysis method, providing various spatial and dynamic information in a timely manner, and establishing a computer technology system for geographic research and decision-making services, is a collection of computer science, surveying and mapping, geography, space science, mathematics, statistics, and management. With its efficient data management capabilities, spatial analysis, multi-element comprehensive analysis and dynamic monitoring capabili...
