Embodiment Construction

[0013] Such as figure 1 As shown, the weather map client mainly includes functions such as map style setting, map browsing, zooming interaction, and viewing details. The weather map server mainly includes map generation, weather symbol visualization, and system tool modules. The data layer includes spatial vector data and map tile data.

[0014] 1. Style setting All the features of the map are described in an xml file. The layer structure of the map is the tree structure of xml. Each layer contains a geographic data source and multiple styles. The style contains multiple rules, one Rules can contain a variety of symbols, and different symbols contain different attribute settings. Take LineSymbolizer as an example, including stroke (color), stroke-width (width), transparency (stroke-opacity), line intersection mode (stroke -linejoin), line head mode (stroke-linecap), line segment drawing iteration interval (stroke-dasharray), etc. A basic map style description xml is as foll...

Abstract

The invention discloses a weather map system with a customizable pattern. A server provides real-time reading and analysis of weather data and generates spatial vector data; a large picture is generated according to a map pattern xml description file provided by a client; the large picture is cut into standard tiles; the tiles are uniformly organized according to TMS (tile map system) rules; the organized tiles and tile files are compressed; all logs are recorded in detail; the client provides map pattern setting that is described as an xml file sent to the server; tile data are acquired fromthe server to provide map browsing and interaction; the client is communicated with the server through currently-popular efficient ZeroMq message queue; the tile data are transceived for MD5 check, sothat data transceiving is intact and correct.

Description

technical field [0001] The invention belongs to the field of meteorology, and in particular relates to a weather map system with a customizable style. Background technique [0002] With the development of science and technology, informatization has become more and more important in all aspects. The convenience brought by informatization to human beings has changed our life drastically. After entering the 21st century, the construction of informatization has further attracted the attention of countries all over the world. The role of informatization is particularly prominent in information management. The advantages of information management are: saving manpower, convenient operation, easy to learn, fast implementation, avoiding mistakes, etc. Among them, the importance of informatization in the field of meteorology is becoming more and more prominent, which is very meaningful for displaying rich meteorological and geographical information and making reasonable predictions...
