Embodiment Construction
[0039] In order to enable those skilled in the art to better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described The embodiments are only some of the embodiments of the present application, but not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without creative efforts shall fall within the scope of protection of this application.
[0040] The workload of the whole process of digital chart drawing (such as figure 1 shown) is mainly composed of four parts: map editing workload, homework workload, review workload, and acceptance workload (self-calibration workload and proofreading workload). Among them, the operating workload (also referred to as the cartographic work...

The invention discloses a method and a device for evaluating the drawing workload of a digital nautical chart, and the method comprises the steps: determining the vectorization workload during the drawing of the digital nautical chart based on the feature information of a plurality of elements in the digital nautical chart; determining a drawing comprehensive influence factor of the digital chart based on the drawing information of the digital chart and drawing data information corresponding to the digital chart; determining the drawing modification workload of the digital nautical chart based on the feature information of the modification elements required when the digital nautical chart is modified; and based on the vectorization workload, the drawing comprehensive influence factor and the drawing modification workload, evaluating the drawing workload of the digital chart. According to the embodiment of the invention, intelligent and objective evaluation of the digital chart drawing workload can be achieved without relying on evaluation personnel, so that the time required for workload evaluation can be reduced, and the evaluation efficiency is improved.
Description
technical field [0001] This application relates to the field of data processing of digital nautical charts, in particular to a method and device for evaluating the workload of digital nautical charts. Background technique [0002] A digital nautical chart is a digital map that depicts the ocean and can be drawn by operators. Usually, after the operator draws the digital chart, it is necessary to evaluate the mapping workload of the operator, so as to conduct other related workload evaluation or workload assessment based on the evaluation result. Among them, the mapping workload of operators can be understood as the process of digital chart data production by operators according to the basic mapping data and correction data specified in the mapping plan. [0003] At present, when evaluating the mapping workload of operators, evaluation members can conduct manual evaluation based on experience. However, in practical applications, this manual evaluation method usually lacks o...
