Method for combining GIS system with split joint wall system and device thereof

Abstract

The invention discloses a method used for combining a GIS system with a splicing wall system and a device thereof. The invention is characterized in that a GIS client terminal and a GIS server terminal are adopted; the operation instruction of the customer is received by the GIS client terminal; a geographical information data is acquired from a GIS data base and an instruction used for acquiring the geographical information data from the GIS data base is generated; the instruction is sent to the GIS server terminal; the GIS server terminal executes a corresponding operation according to the instruction; and the corresponding geographical information is displayed on a splicing wall. Therefore, the invention has the advantages that the instruction which is sent to the GIS client terminal by the GIS server terminal comprises operation information, thereby being small in the data transmission quantity; the data obtained from the GIS data base is displayed on the GIS server terminal, thereby ensuring the quality of the image, effectively utilizing the high resolving capability and high definition of the splicing wall, and effectively achieving the combination between the GIS system and the splicing wall system; besides, the customer only needs to operate at the GIS client terminal, thereby being convenient for operation.

Description

technical field [0001] The invention relates to the application technology of the GIS system, in particular to a method and a device for combining the GIS system with the splicing wall system. Background technique [0002] GIS (Geographic Information System, geographic information system) is a computer system that uses modern computer graphics and database technology to process geographic space and related data. It integrates geography, surveying, geometry, computer science and application objects. The most important feature of GIS is that it can organically combine the geographical location and characteristics of space objects on the earth's surface, and display them intuitively through computer screens. Therefore, GIS geographic information systems are widely used. It is used in planning, land, transportation, electric power, public security and other industries, and the splicing wall system is generally composed of display units, image controllers, large-screen applicatio...

Problems solved by technology

[0004] The defect of the first method is that since the content displayed by the GIS terminal needs to be compressed, transmitted, decompressed and other operations, the display refresh rate of the user on the video wall will be relatively slow. The displayed content is adjusted to fit the display screen of the terminal, and the resolution of the GIS terminal as the signal display source is relatively low. When the content displayed on the terminal is transmitted to the splicing wall, the pixels of the displayed content do not change, but due to The screen of the splicing wall is much larger than the screen of the GIS terminal, and the distance between the pixels of the displayed content is extended, so that the content displayed on the splicing wall is not clear enough, so the high-resolution advantages of the splicing wall cannot be fully utilized, and the display effect is not ideal; The disadvantage of the two methods is: as a terminal of the GIS system, the user has to operate against the splicing wall, which is inconvenient to operate
