Abstract
Purpose. This article is devoted to the review of the modern methods of the designations creation for the We-maps type geographic information systems (GIS). Those kinds of designations are wide-ranged and are gathered in the whole libraries of symbols. Methodology. The methodologies involve determining the sequential steps that must be followed when creating information designations that are appropriate for the We-maps use. The process of creating any map includes a generalization of reality. Ordinary users and commercial companies both are interested in geographic information data, which accelerate this area developing speed today. Originality. The authors introduces their own authentic creation method for the We-maps type GIS designations. The main key of this idea is the usage of QR-codes; the combination of the symbol with QR-code which will minimalize the losses during the recognition. Basic information about the object is stored in the QR-code. The implementation of the idea was done in JavaScript with the use of the API service Amap.com which is the leader of geographic information systems in China. The API service was selected, because the other GIS systems are either banned (Google maps) or uninformative (Yandex maps). This implementation is represented by a marked map with authentic symbols. The geocenter of map is the Lanzhou Jiaotong University. Results. This map itself is a web page that is materialized by using hyper markup language (Html). When loading the web page sends a request using JavaScript language to the web service to build the map. Several tools are situated on the map: the zoom bar and the user's geolocation. Information about the user's location is received from the GPS coordinates of the user or by the IP address of the nearest point on the network. The map has a 3D layer of the objects repre-sentation for the ground orientation convenience. This information is located on the free git service GitHub in the public domain. A code was generated for users to open this map. The code can be scanned by any device that has a camera and a scanning program.
