Embodiment 1

[0052] Please refer to figure 1 , Embodiment 1 of the present invention is: a map data inspection method, which can be applied to the electric power basic map construction service project, realizes the inspection of the attribute data of the basic geographic data, and the topology inspection of the graphic data, and realizes the intelligence of some problems modification.

[0053] This embodiment mainly includes attribute data checking and graphics data checking.

[0054] For attribute data inspection, the following steps are included:

[0055] S101: Load the map data to be checked, the map data includes multiple layers, and the same layer corresponds to the same geographic element; the geographic elements include natural geographic elements such as water systems, vegetation, and socioeconomic elements such as residential areas and roads , where each geographic element contains multiple types, such as roads include expressways, national roads, provincial roads, county roads,...

Embodiment 2

[0074] This embodiment is a computer-readable storage medium corresponding to Embodiment 1, on which a computer program is stored, and when the program is executed by a processor, the following steps are implemented:

[0075] Loading the map data to be checked, the map data includes multiple layers, and the same layer corresponds to the same geographic element;

[0076] According to the preset configuration file, check the attribute data of each layer and each geographic element therein, and the attribute data check includes layer name check, layer attribute structure check, feature coding check and attribute value range check;

[0077] Carrying out a graphic topological relationship check on the map data, the graphic topological relationship check including a navigation road connectivity check, a vector road section check, and a face-to-surface overlap check;

[0078] If an error is detected, the error information is recorded in the problem record table, and the problem recor...

Abstract

The invention discloses a map data inspection method and a computer readable storage medium, and the method comprises the steps of loading to-be-inspected map data which comprises a plurality of map layers, and enabling the same map layer to correspond to the same geographic element; according to a preset configuration file, performing attribute data check on each layer and each geographic elementin the layer; performing graphic topological relation check on the map data, wherein the graphic topological relation check comprises navigation road connectivity check, vector road section check andsurface-to-surface overlapping check; if an error is detected, recording the error information in a problem record table, and the problem record table comprises a layer name, an element code value and problem description; and correcting errors checked in the graphic topological relation check. According to the invention, the accuracy, comprehensiveness and convenience of data checking can be improved, and the drawing checking efficiency and correction efficiency can be improved.

Description

technical field [0001] The invention relates to the technical field of data inspection, in particular to a map data inspection method and a computer-readable storage medium. Background technique [0002] At present, the ARCGIS software checks the basic geographic data with cumbersome steps. The attribute data inspection can only be checked manually by checking the name, type, length, and value range of each field in the attribute table. Facing massive data, it is easy to cause misjudgment and waste time. waste. Graphical data inspection involves a series of operations such as data storage, new topology, definition of coordinates, setting tolerances, adding rules, and validating topology, and lacks intelligent modification functions. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a method for checking map data and a computer-readable storage medium, which can improve the accuracy, comprehensiveness and convenien...
