Description
Technical field
The present invention relates to a kind of cartography technology, particularly relate to a kind of tile map method for making and system.
Background technology
Tile map pyramid model is a kind of multiresolution hierarchical model, and from the pyramidal bottom of tile to top layer, resolution is more and more lower, but the geographic range represented is constant.First the quantity N of the level of zoom that map service platform will provide is determined, the maximum map picture of level of zoom is minimum, map scale is as pyramidal bottom, namely the 0th layer, and piecemeal is carried out to it, from the upper left corner of map picture, cut from left to right, from top to bottom, be divided into the square map tile of formed objects (such as 256x256 pixel), form the 0th layer of tile matrix; On the basis of the 0th layer of map picture, the method synthesizing a pixel by every 2x2 pixel generates the 1st layer of map picture, and carries out piecemeal to it, is divided into the square map tile with lower one deck formed objects, forms the 1st layer of tile matrix; Adopt generation the 2nd layer of tile matrix that use the same method; ...; So go down, until N mono-1 layers, form whole tile pyramid.
Traditional WebGIS is Real time request map server transmission map, effectively can react the Up-to-date state of map; And under the grille picture that tile map is pre-generatmg rule is stored in hard disk catalogue, map is to link the mode fast custom of picture.Two kinds of patterns have obvious difference in the speed of asking and respond, and the response speed of tile map is wanted obviously faster than traditional WebGIS, simultaneously also corresponding smaller to the load of map server.
After the map location service that Google Map release Tile Map Image mode provides, the special map search companies such as domestic go2map, mapabc, mapbar imitate one after another, the WebGIS new model released one after another based on map tile pyramid model, and this pattern is also becoming the normal mode that various enterprise Web GIS applies.
In order to make tile map, each GIS manufacturer provides different drafting instruments, and its method is: first, determines tile certain rank pyramidal (namely determining the engineer's scale of map); Then, the one or more vector used by map or raster map layer data are loaded, for each layer configures corresponding displaying symbol pattern and word annotation pattern; Finally, according to certain rule by map rasterizing, and cut into some little pictures, be kept at corresponding position.Afterwards, determine the pyramidal another one rank of tile, repeat aforesaid operations until complete the pyramidal making of whole tile.
The shortcoming of prior art is mainly manifested in:
1, pyramidal each rank respectively figure make, in manufacturing process, cannot preview fast complete after appearance.Usually, the cutting of tile map, the amount of output are very large, if after cutting completes, just can only pinpoint the problems, so, remodify figure pattern, again cut.This is by serious image work efficiency.
2, the parameter such as the displaying ratio of each rank and picture size is arranged respectively, adds the complicacy of software application, also considerably increases the possibility of drawing personnel maloperation simultaneously.
Summary of the invention
The object of the invention is to, provide a kind of tile map method for making and system, compensate for when figure cannot the deficiency of live preview net result, the efficiency of improve tile pyramid figure, publishing picture.
