A method and system for drawing an industrial project area map

Abstract

The invention discloses a method and system for drawing a map of an industrial project area. The method includes generating an empty .db database in a map data server; obtaining remote sensing images of the area to be drawn and attribute information of industrial items in the area to be drawn , extract the features in the remote sensing image, and determine the geographic location of the industrial project area according to the extracted features and the attribute information of the industrial project in the area to be mapped; where the attribute information of the industrial project includes the category, shape, and area of ​​the industrial project And the distance information with the surrounding features; according to the geographical location, shape and area of ​​the industrial project area, determine the control point coordinate data of the industrial project position, and fill it into the empty .db database; read the .db database, and The area determined by the control point coordinate data in the .db database is rendered and sent to the client for display.

Description

technical field [0001] The invention belongs to the field of map drawing, and in particular relates to a method and system for drawing an industrial project area map. Background technique [0002] Industrial projects include agricultural, forestry, urban and industrial projects. When designing an industrial map, the required industrial map data is provided by the customer, but most of the customers cannot provide the exact geographic coordinate data of the project. They only know the text description of the general location of the project, and cannot obtain accurate coordinate location information. A lot of manpower and material resources are wasted by manually searching for location and entering coordinate information. In addition, when the map data server is not connected to the Internet, the map of the industrial project area cannot realize the purpose of offline preview and query. Contents of the invention [0003] In order to solve the shortcomings of the prior art,...
