Problems solved by technology

This phenomenon that the new and old stakes on the same route cannot be matched or the stakes of the front and rear sections cannot be kept continuous at the connection will cause a series of problems when positioning highway mileage stakes, such as position offset during positioning Or the positioning position is wrong, and the setting of the mileage pile loses its original design purpose, which brings a lot of inconvenience

Abstract

The invention relates to an electronic map milepost data collecting and updating method. Electronic milepost data is collected and fused according to automobile navigation electronic map space data, roadside facility space data and two different data sources including road and roadside facility road industry collection data supplied by a road network center, the fused data can achieve the advantages of high quality of the navigation data and accurate attributes of the road industry collection data simultaneously, and changed milepost information is displayed in time by means of a dynamic segmentation technique.

Description

technical field [0001] The present application relates to a method for collecting and updating electronic map data, in particular to a method for collecting and updating electronic map mileage post data based on data collected by the highway industry. Background technique [0002] After years of development and construction, great achievements have been made in my country's highway geographic information construction, but there is a lack of unified data standards and norms, as well as a collaborative and efficient highway information data reporting and management system. As a scientific road positioning method, the mileage post clearly indicates the name and kilometers of the road in detail and accurately. With the help of the mileage post information, it is convenient to calculate the length of the route or road section, and quickly perform accurate geographical location on the road. The mileage The setting of the pile is to provide a positioning reference point along the r...
