Embodiment Construction

[0030] In general, the scale multiples of each level, the size and format of the cut pictures, etc. in a pyramid production plan are fixed. Based on this premise, the present invention proposes a method and system for making a tile map pyramid model, that is, first determine the pyramid After that, configure maps for each level of the pyramid under a unified interface, and display the appearance after production in real time during the configuration process, and finally output the map uniformly.

[0031] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0032] Such as figure 1 As shown, the embodiment process of the method for making a tile map of the present invention includes:

[0033] Step 102, setting various parameters of the tile map pyramid model;

[0034] Such as figure 2 As shown, set various parameters. The parameters of the tile map pyramid model include:

[0035] (1) Map range: that is, to determine the ge...

Abstract

The invention discloses a tile map manufacturing method and system. The tile map manufacturing method includes setting various parameters of a pyramid model of a tile map; generating a layer data list of the pyramid model according to the parameters and performing the visualization configuration of the layer data list in a WYSIWYG (what you see is what you get) mode; and manufacturing the pyramid model of the tile map according to the configured layer data list. According to the tile map manufacturing method, the various parameters of the pyramid is firstly determined, then every level of the pyramid is configured with a map body in a unified interface, the completed appearance of the pyramid model of the tile map is presented in real time during configuration, and at last the map is produced in a unified mode. Therefore, the shortcoming that the final result of the tile map cannot be previewed during map configuration is overcome, and the map configuration and map production efficiency of the pyramid model of the tile map is improved.

Description

technical field [0001] The invention relates to a map making technology, in particular to a tile map making method and system. Background technique [0002] The tile map pyramid model is a multi-resolution hierarchical model. From the bottom layer to the top layer of the tile pyramid, the resolution becomes lower and lower, but the geographical range represented remains the same. First determine the number N of zoom levels to be provided by the map service platform, and take the map picture with the lowest zoom level and the largest map scale as the bottom layer of the pyramid, that is, layer 0, and divide it into blocks, starting from the upper left corner of the map picture, Cut from left to right and from top to bottom, and divide into square map tiles of the same size (such as 256x256 pixels) to form the tile matrix of the 0th layer; on the basis of the map image of the 0th layer, it is synthesized by every 2x2 pixels Generate the map image of the first layer for the me...
