Problems solved by technology

Since civilian short messages have a limit of 120 characters and a limit of 1 minute / article transmission frequency, if you transmit symbolized raster results or source map data through short messages, you need to consider the problem of subcontracting, and the timeliness is greatly reduced , unable to meet the needs of emergency quick display

Abstract

The invention relates to an emergency map symbolization method based on a Beidou short message. An emergency map publishing side and an emergency drawing terminal are included; the emergency map publishing side identifies a short message used for emergency map symbolization, extracts symbolization related map symbol description and display control style information required by emergency map symbolization, furthermore, performs text coding on the short message according to a symbol description rule and a display style coding rule, and sends coded data to a Beidou communication satellite througha Beidou short message; and the emergency drawing terminal receives the short message from the communication satellite, analyzes the short message based on the symbol description rule and the displaystyle coding rule to obtain symbolization information of an emergency map, completes emergency map symbolization in the emergency map layer of the emergency drawing terminal, and performs displaying.According to the emergency map symbolization method based on the Beidou short message disclosed by the invention, the Beidou short message used as a carrier is used for transmitting emergency map symbolization information; emergency map symbolization is completed at the terminal; and thus, display requirements on emergency events and resources in an emergency condition can be satisfied.

Description

technical field [0001] The invention relates to the field of information technology processing, in particular to an emergency map symbolization method based on Beidou short messages. Background technique [0002] Map symbolization provides users with clear display expressions by configuring the symbols, annotations and display styles of map data. Map symbolization can be done locally on the map data, such as "A method of ground object symbolization to realize the integration of image library" (application number: 201310176981.0), "an electronic map drawing method based on basic geographic information data" (application number: 201410059552.X), "A Rapid Mapping Method for Batch Symbolization" (Application No.: 201010266463.4), "A System and Method for Generating Emergency Resource Situation Map Based on GIS" (Application No.: 201410709234.3), the symbolization results are as follows The raster form is transmitted to the client for display, such as: "A fast symbolic display m...
