Classifier and the library of conventional symbols for a digital large-scale navigation plan were developed

10.04.2018

In KB "Panorama" the classifier and library of conventional symbols of the digital large-scale navigation plan were developed. Digital large-scale navigation plan (LSNP) is a digital thematic map containing information about spatial objects sufficient for solving the problem of automated location of a vehicle on the road and calculation of the route of its movement, taking into account the lane traffic, a marking and information of road signs.

Classifier LSNP is made taking into account the requirements: "GOST Р  51256-99. Technical facilities for organizing road traffic. Road marking. Types and basic parameters. General technical requirements"; "GOST Р  52282-2004. Technical facilities for organizing road traffic. Road traffic lights. Types and basic parameters. General technical requirements. Test methods"; "GOST Р  52290-2004. Technical facilities for organizing road traffic. Road signs. General technical requirements".

LSNP is created on the basis of high-precision satellite geodetic measurements corresponding to the accuracy of digital topographic plans of scale 1: 500. Unlike digital navigation maps and digital city plans, where the road is represented by a linear object, on LSNP the road is represented by a set of polygonal, linear and point objects, characterizing all its arrangement. The use of the road2000.rsc digital classifier ensures the automatic loading of data from mobile laboratories intended for collecting data on the state of highways and adjacent objects. Loading is provided by tools of the GIS "Panorama".

The downloaded information is published as a web-service - digital road model (DRM). The service provides information to external information systems under the unified protocols OGC WMS and WFS. Structure of the DRM web-service includes: digital cartographic substrate, road objects, roadside infrastructure and services, high-precision navigation information presented by the road graph, conditions and traffic modes. GIS WebService SE is used to publish the DRM on the Internet.

The classifier and the documentation to it are available on the site in the Classifiers section.
