Embodiment 1

[0063] see figure 1 , figure 2 , image 3 and Figure 4 The method for producing maps based on standard map services proposed in this embodiment specifically includes the following steps:

[0064] Step S101: the server obtains the current accuracy of the GIS image.

[0065] First, let’s introduce the GIS pictures displayed in the GIS one-map system. Usually, the GIS pictures in the GIS one-map system are three-dimensional. When people want to view GIS pictures from different angles, they can rotate the above GIS pictures. To obtain the GIS picture of the perspective you want. Moreover, GIS pictures can also obtain GIS pictures of different levels (that is, different zoom ratios) according to the layer, level, and precision relationship defined by the slicing scheme, for example, a 1:200 map of a certain county and a map of a certain county at 1:500.

[0066] The above step S101 is described in detail below:

[0067] Step S1011: The server receives the coordinate values ...

Embodiment 2

[0106] see Figure 5 , this embodiment provides a drawing device based on standard map services including:

[0107] The current precision acquisition module 1 is used for the server to acquire the current precision of the GIS picture.

[0108] The layer precision acquisition module 2 is used for the server to acquire multiple different layer precisions according to different slicing modes of the GIS image.

[0109] The fusion operation module 3 is used for the server to perform a fusion operation on the GIS pictures corresponding to each layer precision one by one according to the current precision, and obtain an output picture for each fusion operation until all the GIS pictures corresponding to the layer precision are fused.

[0110] The image synthesis module 4 is used for the server to combine multiple output images into a standard output image, and return the standard output image to the browser.

Abstract

The present invention provides a drawing method and device based on a standard map service, and relates to the technical field of picture synthesis, wherein the drawing method based on a standard map service includes: first, the server obtains the current precision of the GIS picture, and then, the server obtains the current accuracy of the GIS picture according to the GIS picture Different slicing methods can obtain multiple different layer precisions. Secondly, the server performs fusion operations on the GIS images corresponding to each layer precision one by one according to the current precision. Each fusion operation obtains an output picture until all layer precisions The corresponding GIS pictures have all completed the fusion operation. After that, the server combines multiple output pictures into a standard output picture, and returns the standard output picture to the browser. Through the above-mentioned processing of the server, people do not need to manually operate in the browser. Steps to enable people to obtain a map based on standard map services conveniently and quickly.

Description

technical field [0001] The invention relates to the technical field of picture synthesis, in particular to a method and device for outputting pictures based on standard map services. Background technique [0002] GIS stands for Geographic Information System (GIS for short). A map system is a comprehensive management and application system based on basic spatial data and various professional spatial data. and analysis to realize the linkage display and management of spaces and attributes. The GIS one-map system is based on lightweight browser browser access, but it has disadvantages in the management of spatial GIS data, for example, the GIS data output in the input and output functions, because the browser directly operates GIS data, files and IO ( Input / Output) and other operation interactions are limited. [0003] However, in the process of direct use of the GIS one-map system, if customers want to print out the data of key map locations, for example, superimpose the red...
