Abstract
In order to improve the scientificity and efficiency of quality inspection of navigation electronic map, and save the cost of quality inspection, it is necessary to establish the national navigation electronic map quality inspection sample database. In this paper, the construction goal, data acquisition technology process, and database construction method of navigation electronic map quality inspection sample database are described in detail, and the construction content and technical indicators are discussed. The quality test is carried out by combining the in-house verification with the field comparison of the navigation electronic map quality test sample database, and the test results are analyzed and evaluated. The effective application of the sample database in the quality test and evaluation of the internet navigation electronic map in the pilot area is carried out. At the same time, the application of navigation electronic map quality inspection sample database in the research of urban fine management and solid waste recycling economy ecological park planning is prospected.
Highlights
With the development of communication, electronics, network technology, and the geographic information industry, map navigation products have been widely used in people's daily life [1,2]
Organize the quality inspection practitioners to carry out the quality inspection test by combining the in-house verification and field comparison in the navigation electronic map quality inspection sample database as a group, and analyze and evaluate the test results
The evaluation methods and experimental results are as follows: 4.1 Evaluation method The score of test results is calculated according to the proportion of errors and omissions of different levels, and the score is shown in the formula (1)
Summary
With the development of communication, electronics, network technology, and the geographic information industry, map navigation products have been widely used in people's daily life [1,2]. The field work of road network information collection is mainly based on the image and the 1:10000 road data in the sample area to carry out on-site verification and mapping, and record the driving track in the whole process to complete the collection of road morphology and structure. In each sample area, according to the complexity of road and poi, the area of not less than 4 square kilometers is cut as the sample area of the actual test.The data in the navigation electronic map quality inspection sample database obtained by field measurement is taken as the reference data of the sample area. The above test results show that the quality evaluation method based on the navigation electronic map quality inspection sample database can evaluate the quality of Internet navigation electronic map service well, and reflect the fine differences in data and services of various Internet map service providers
