Problems solved by technology

[0004] The object of the present invention is to provide a method for displaying image files and a method for group management, so as to solve the problem that the memory required to be occupied is getting larger and larger as the information recorded in the geographic reference data increases significantly in the prior art. However, the increase of the file size will often lengthen the data processing time, resulting in the decline of the operating efficiency of the geographic information system and the inconvenience of use.

Embodiment Construction

[0033] Please refer to figure 1 , figure 1 It is a schematic block diagram of an embodiment of the image file processing device of the present invention. The image file processing device 10 includes a display processing unit 11 , an image processing unit 13 , a storage unit 15 and a display unit 17 , wherein the image processing unit 13 , the storage unit 15 and the display unit 17 are all electrically connected to the display processing unit 11 . The image file processing device 10 may be implemented by a general computer system, such as an industrial computer or other types of server hosts and the like.

[0034] When an image file (such as a picture such as a map or a vector graphics file) is input into the image file processing device 10, it will be sent to the image processing unit 13 for image processing, and then sent to the storage unit 15 for storage. After receiving the image file, the image processing unit 13 divides the image file into a plurality of image regions...

Abstract

Disclosed is a display method of an image file and a group management method. The steps of the group management method are as follows. An image file is received, wherein the image file is divided into a plurality of image zones according to presupposed divisions. An image group management layer aiming at the image file is produced, wherein the image group management layer records common attribute data of the image zones of the image file. A plurality of zone data which correspond to the image zones are recorded into the image group management layer. Zone segmentation treatment of the image file is achieved, so needed time for processing the image file is reduced, and display efficiency and practical value of the image file are improved.

Description

technical field [0001] The invention relates to a management method of image files, in particular to a group management method and display method of image files. Background technique [0002] Geographic Information System (GIS) is a comprehensive subject that combines geography and cartography and has been widely used in different fields. It is a calculator for inputting, storing, querying, analyzing and displaying geographic data. system. Geographic information system belongs to the category of information system, which can deal with geo-referenced data, in which geo-referenced data describe the location and attributes of spatial elements on the earth's surface (such as the atmosphere and shallow subsurface space), and can be divided into spatial data (spatial data) ) and attribute data. Spatial data includes legends and objects of points, lines or surfaces related to positions, while attribute data describes the connotation and information of the objects and legends. ...
