Problems solved by technology

The electronic map made in this way stores a series of graphics with a huge amount of data, and uses a professional computer platform to connect the built-in or external relational database with it, but the relationship between each map and the different information in the same map The relationship between cannot be directly reflected, it is difficult to quickly query the required information
At the same time, although the electronic map produced by this method pays attention to the accuracy of geographical location, it must pay a huge price for storage. In addition to the expensive cost of the GIS professional platform, the application unit also needs to bear the cost of the relational database platform. Expensive

Embodiment Construction

[0030] The first step is to classify the information that constitutes the electronic map: the information that constitutes the electronic map is divided into frame information and additional information. The frame information is road information, which constitutes the outline of the electronic map. The frame information is composed of nodes and links. Additional information includes geographic information and advertisement information, which describes the details of the electronic map. Additional information is composed of place names, coordinates, absolute names, classifications, and advertisement content. like figure 2 As shown, the intersection of lines in the figure is a node, and the line between two nodes is a link. There are various symbols in the figure, such as: circle, ellipse, square with round corners, triangle, square, etc. Each symbol represents a class of additional information.

[0031] The second step is to layer the electronic map that needs to be produced:...

Abstract

The invention relates to a method for making electronic maps characterized by that, it uses the road information as frame information, and forms the contour of the map through nodes and links, it also uses the geographical information and advertising information as the additional information, describing the details of the map by means of coordinates, absolute names and advertising contents, it integrates all the information for level administration and can store and display the road traffic status, facilities along the road, the path and distance of the destination. The map can be used to analyze the traffic information and the city condition with small storage space and low cost in mobile terminal. The electronic map made by the method has the advantages of clear layer, easy searching, extensive information and strong practicality.

Description

technical field [0001] The invention relates to an electronic map, in particular to a method for making an electronic map. Background technique [0002] At present, the well-known electronic map is based on the GIS system, and its data processing model is established on the massive digital geographic background map. After superimposing various professional icons to form a special layout map, and then using the built-in or plug-in relational database, Query the parameter records to which statistical graphic symbols belong, so as to be used in planning, municipal administration, land management, electric power, telecommunications, tap water, transportation and other related industries. The electronic map made in this way stores a series of graphics with a huge amount of data, and uses a professional computer platform to connect the built-in or external relational database with it, but the relationship between each map and the different information in the same map The relation...
