Description
Technical field
The present invention relates to maps processing method, particularly relate to a kind of based on the self-defined Map of electronic third-party mapping
The method of layer.
Background technology
Cartography is the research theory of map, establishment technique and the science of application process.Traditional cartography is to utilize
Paper and pen is main tool, and along with the progress of science and technology, cartography has changed to be drawn by computer.Including CAD (CAD (computer aided design)),
GIS (GIS-Geographic Information System) or some map painting softwares.The function of map is as the space data of visualization, and space data is
By measure, and can store up in data base, current makes from the drafting method of analogy toward electronics and interaction.Electronically
Figure, i.e. numerical map, is to utilize computer technology, the map storing in a digital manner and consulting.Electronic chart stores information
Method, generally uses vector mode image storage, and map scale is enlarging or reducing or rotates and does not affect display effect.Electronically
Scheming the difference maximum with paper map to be, electronic chart can scale, and the map that each level after scaling is shown
Interior different.It is stitched together composition it is true that the electronic chart that we are seen is numerous tile figure layer.And existing
In technology, it is by the whole figure layer of original electronic chart is processed or revises to the process of electronic chart or amendment etc.,
Its workload is big, waste of manpower.
Summary of the invention
Embodiment of the present invention technical problem to be solved is, for the existing process to electronic chart or amendment etc.
Being by the whole figure layer of original electronic chart is processed or revised, its workload is big, the problem of waste of manpower, it is proposed that
A kind of method based on the self-defined map layer of electronic third-party mapping.
In order to solve above-mentioned technical problem, embodiments provide one and make by oneself based on electronic third-party mapping
The method of justice map layer, should method based on the self-defined map layer of electronic third-party mapping include: at map base map
Upper labelling target area；Obtain all tile figure layers in target area；All tile figure layers are spliced into a complete ground
Figure picture, and derive；Based on the map picture derived, drawing software is used to carry out map copying the figure drawing self-defined pattern
Layer；Map in self-defining image layer is cut and is decomposed into new tile figure layer, and with the coordinate one_to_one corresponding of former tile figure layer, based on
Coordinate covers on map.
Wherein, when obtaining all tile figure layers in target area, record the coordinate of the tile figure layer of a jiao simultaneously；To
When new tile figure layer is with former tile figure layer one_to_one corresponding, carry out correspondence according to tile figure layer coordinate.
Wherein, tile figure layer coordinate includes x-axis coordinate and y-axis coordinate.
Wherein, former tile figure layer and new tile figure layer are the tile figure of 256*256 specification.
Wherein, the quantity of new tile figure layer is identical with the quantity of former tile figure layer.
Implement the embodiment of the present invention, have the advantages that loading based on electronic third-party map of the present invention is made by oneself
The method of free burial ground for the destitute figure uses the tile figure layer in the range of extracting, and makes drawing thereon, then drawing is decomposed into new tile
Figure layer, interface based on third party's map loads self-defined map layer, and step is simple, it is not necessary to use the map edit of specialty
Map is edited and revises by instrument and knowledge, saves manpower and skill learning cost.
Accompanying drawing explanation
In order to be illustrated more clearly that the embodiment of the present invention or technical scheme of the prior art, below will be to embodiment or existing
In having technology to describe, the required accompanying drawing used is briefly described, it should be apparent that, the accompanying drawing in describing below is only this
Some embodiments of invention, for those of ordinary skill in the art, on the premise of not paying creative work, it is also possible to
Other accompanying drawing is obtained according to these accompanying drawings.
Fig. 1 is the stream of the method based on the self-defined map layer of electronic third-party mapping of first embodiment of the invention
Cheng Tu.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Describe, it is clear that described embodiment is only a part of embodiment of the present invention rather than whole embodiments wholely.Based on
Embodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under not making creative work premise
Embodiment, broadly falls into the scope of protection of the invention.
Refer to Fig. 1, Fig. 1 be first embodiment of the invention based on the self-defined map layer of electronic third-party mapping
The flow chart of method.In the present embodiment, method based on the self-defined map layer of electronic third-party mapping includes:
In step s 11, labelling target area on map base map.In this step, it is possible to use on original map
Zone boundary determine the target area of institute's labelling.Such as, choose the Yellow Crane Tower sight spot of Wuhan City, convenient with on original map
The border at the Yellow Crane Tower sight spot of labelling, determines that the target area of labelling is the map at Yellow Crane Tower sight spot.Also may be used in target area
With Shi Yige community etc..Or, multiple point being sequentially connected with can be set on map base map by user and iris out a mesh
Mark region.
In step s 12, all tiles in target area are obtained.When obtaining all tile figure layers in target area,
Record the coordinate of the tile figure layer of a jiao simultaneously.Tile figure layer coordinate can include x-axis coordinate and y-axis coordinate.
In step s 13, all tile figure layers are spliced into a complete map picture, and derive.
In step S14, based on the map picture derived, drawing software is used to carry out map copying drafting self-defining image
The figure layer of case.
In step S15, the map in self-defining image layer is cut and is decomposed into new tile figure layer, and with former tile figure layer
Coordinate one_to_one corresponding, covers on map based on coordinate.When by new tile figure layer and former tile figure layer one_to_one corresponding, according to watt
Sheet figure layer coordinate carries out correspondence.
Wherein, former tile figure layer and new tile figure layer are the tile figure of 256*256 specification, and the quantity of new tile figure layer
Identical with the quantity of former tile figure layer.
Implement the embodiment of the present invention, have the advantages that making by oneself based on electronic third-party mapping of the present invention
The method of justice map layer uses the tile figure layer in the range of extracting, and makes drawing thereon, then drawing is decomposed into new
Tile figure layer, interface based on third party's map loads self-defined map layer, and step is simple, it is not necessary to use the map of specialty
Map is edited and revises by edit tool and knowledge, saves manpower and skill learning cost.
The foregoing is only presently preferred embodiments of the present invention, not in order to limit the present invention, all essences in the present invention
Within god and principle, any modification, equivalent substitution and improvement etc. made, should be included within the scope of the present invention.
