A geographic information providing method using dynamic parallel drawing of the space vector data

摘要

Provided is a method of providing geographic information using a dynamic parallel drawing of spatial vector data capable of directly performing drawing in parallel by using a graphic buffer without waiting. The method of providing geographic information using a dynamic parallel drawing of spatial vector data allowing a cash sever having a geographic information system server, including a request receiving unit, a DB request unit, a threadpool control unit, and a drawing control unit, and a cash memory to provide a map image to a user terminal includes: a step (a) of, by the request receiving unit, receiving request space information required to generate a map image from the user terminal, parsing the information by layer, and requesting work assignment from the threadpool control unit; a step (b) of, by the threadpool control unit, assigning a work to a thread according to whether a valid thread exists in the thread pool by analyzing the parsed request space information, and fetching the spatial vector data of the request space information from a space DB server; a step (c) of, by the drawing control unit, generating a graphic object used for drawing by receiving the fetched spatial vector data and drawing and merging the graphic object in parallel using a map symbol; and a step (d) of returning the merged image to the user terminal.
