On the road \

Method to collect location data. Its accuracy should not be less than 1:5 million scale topographic map data accuracy. This location data can make the accuracy of field measurements on the principles of macro-control. The accuracy of the map itself is the size of the changes with the scale,[link widoczny dla zalogowanych], the graphics can also be amplified through a variety of technology and downsizing, but the field on the road \The location there is a certain gap or known errors. Therefore, the question at all levels of the exchange with the chart, but also passing the corresponding real Shu data records, to facilitate the revision and updating graphics, bringing them closer to the actual value of the location of point coordinates. The aim is to create the map, the computer and the spatial location of the correspondence between the field to protect the road spatial data accuracy and consistency of resources, 8,[link widoczny dla zalogowanych], highway location reference system for the conversion of space and the Gaussian plane rectangular 8.1 latitude and longitude coordinates convert latitude and longitude of the earth and the Gaussian plane rectangular coordinate conversion by the relevant mathematical formula Geodesy build relationships and conversion. 8.2 miles pile and latitude and longitude or Cartesian control requirements of this standard mileage Stake earth surface features and the field should be the latitude and longitude coordinates or plane rectangular and Gaussian one relationship established. Stake refers to the length of the road reference system, the main highway control points, reference point and an important milestone Stake mileage points, but also with the computer,[link widoczny dla zalogowanych], identification number on the map or the map coordinates to establish one to one relationship. Figure 8.3 on the highway mileage of the actual mileage and actual mileage conversion of road and topographic map data should be the corresponding vector segments to establish the road between the control and conversion. The mathematical formula for the relationship; conversion parameter b the length of a section of a map I / This section of Highway Mileage L8, d 5d coordinate conversion between the coordinate system to reference system 80 coordinates the position of highway by Gifl2409 shall coordinate coordinate system used in 1980 in Xi'an. Pull the country's history, due to adopt the 1954 Beijing coordinate system, information system applications in surveying and mapping departments according to the parameters given in respect of Xi'an coordinate system into I980. And WGS8 ~] coordinates of the castration of the conversion. Geodetic coordinate system of national road-based reference system and data conversion between WGS84 coordinates. Should be provided for the State Bureau of Surveying and Mapping transformation parameters and their mathematical conversion formula. Or in the GPS observation data processing, the starting point} test (reference point) using National Geodetic Coordinate System coordinates, which are also tested directly the anchor was vice corresponding geodetic coordinates. 9, Highway Location Reference Method 9.1 miles along the location in the pile method of identification by the combination of two elements,[link widoczny dla zalogowanych], used to identify any point along the road position. Code and code structure; G (s )×××××/×××× X ~ X means at a highway for a road - line of code is a skeleton of 9.2 road miles Stake servers node connection method that the method identified by the combination of three elements,[link widoczny dla zalogowanych], code and code structure: G (s )×××××/ K ××××××/ persons × x ×. × × 0'jL line of code to fix the code of a distance away from the anchor (or mileage Stake) meaning of a specific route and more distant from the anchor (or how many kilometers) or G (S )××××× / K × × × × xx-K ×××××/ ± × × ×. × × × line of code - an A, has been positioning point (between) the code from the A (+ number) or have (I) and more distant highway anchor positioning method can be chosen with reference to a variety of ways, the aim is to make the scene Position description and computer records two-way between the spatial data query, timely delivery and provide accurate information.
