Embodiment Construction

[0039] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0040] Aiming at the problems of low efficiency and high false detection rate in the current manual digital map inspection, the present invention proposes an automatic inspection method for a digital map, which can be used for the part outside the map and the part inside the map (published part) ). Among them, the part outside the drawing includes drawing outline size check, index number check, drawing name check, area annotation check, note check, etc. The process of each check is as follows:

[0041] 1. Check the outline size

[0042] Load the theoretical size information of the digital map sheet to be checked, combine the latitude and longitude of the map sheet, and use the Gauss-Krüger projection to calculate the outline size of the map sheet, and check the correctness of the size of the map against the theoretical size table. On the o...

Abstract

The invention relates to an automatic checking method for a digital map, and belongs to the technical field of digital map making. According to the method, the overall dimension of the digital map sheet to be checked is determined through projection calculation according to the longitude and latitude of the digital map sheet to be checked, the calculated overall dimension is compared with the theoretical dimension of the loaded digital map sheet to be checked, and the comparison result is annotated outside the digital map sheet to be checked. Through the above process, the method can achieve the accurate and efficient detection of the digital map profile. In addition, the publishing quality of the digital map can be automatically and accurately detected.

Description

technical field [0001] The invention relates to an automatic checking method of a digital map, which belongs to the technical field of digital map drawing. Background technique [0002] The original collected data based on aerospace remote sensing images is the foundation and support of digital topographic maps, and the quality inspection and verification of collected data is an important key link to ensure the accuracy, accuracy and reliability of topographic maps. At the same time, due to the fact that the original data may have many problems such as inaccurate image-based data collection locations, incorrect attributes, and unreasonable editing and processing, as well as the limitations of the existing technical level, there is currently no fast and effective detection means and methods for digital map inspection. Mature products usually only rely on the combination of printed paper diagrams and computer screens for manual inspection, which has a large workload, time-cons...
