Background technique
Information of inviting outside investment map system is to be combined together the information of inviting outside investment in region with cartographic information, so as to enterprise, clothes
Business mechanism, administration person etc. are multi-party to be understood region information of inviting outside investment in time, finds matched trade and investment promotion resource or reasonably recruited
The map system of quotient's management.
Information of inviting outside investment map system is typically different since the scene of application is more in different scenes demand of going down, such as
For administration person, need to get information about the trade and investment promotion situation of current each region on information of inviting outside investment map,
To be merchants inviting work perfecting program.
Currently, in order to enable administration person that can get information about information of inviting outside investment in map, it is common practice to will
On information of inviting outside investment map overlay to geography information figure layer.However, in the case where large scale, as corresponding to unit map
Real space is larger, and existing information of inviting outside investment is also more, if all showing all informations of inviting outside investment, will lead to
A large amount of information of inviting outside investment is excessively intensively difficult to differentiate between identification on map.In response to this, the method generally used at present is
According to pre-set level in information of inviting outside investment, the higher information of trade and investment promotion index is selected to be shown.The drawbacks of this mode, is: (1)
Only it will be seen that the publication situation of index forward portion information of inviting outside investment, cannot understand the distribution situation of information of inviting outside investment totally.(2)
Since the forward information of inviting outside investment of index is easily collected on commercial accumulation regions, the information of inviting outside investment for causing map denotation to come out all concentrates heap
Long-pending and commercial accumulation regions, and the informations of inviting outside investment in other areas can not then be shown.For example, for Dongguan citywide trade and investment promotion map, such as
Fruit is using the investment amount of project proposal for investment as index, then the forward information of inviting outside investment of index can be concentrated mainly on southern city, Guia Hill lake
Region, other remaining then shown substantially without information of inviting outside investment.When this meeting is so that administration person consults a map, in southern city, Guia Hill
Lake region domain is since information of inviting outside investment is excessive, excessively intensive and inconvenience is checked, and other regions are then hardly visible information of inviting outside investment, also without
Method sees whole trade and investment promotion situation, to experience bad.In this regard, current another method is exactly on map according to space point
Cloth uniformly shows information of inviting outside investment, and this mode then causes administration person that can not understand the aggregation situation of information of inviting outside investment, equally
It experiences bad.

Specific embodiment
The invention will be further described with the following Examples.
The invention discloses a kind of trade and investment promotion map system, which is used for the information of inviting outside investment and map letter in region
Breath is combined together, and is understood region information of inviting outside investment in time so that enterprise, service organization, administration person etc. are multi-party, is found matching
Trade and investment promotion resource or carry out the map system of reasonable management of promoting trade and investment.The system includes background end and front end, and background end is for pipe
Reason person increases trade and investment promotion plot newly, nullify (deletion), modification, inquiry, marks and draws and the operations such as scheme rendering, and front end is for looking forward to thing
Industry such as is inquired, is declared at the operation.Manager will form information of inviting outside investment to the operation in trade and investment promotion plot in background end, these letters of promoting trade and investment
Breath collectively forms information of inviting outside investment database, wherein every information of inviting outside investment all includes ancestor ground title, soil position, affiliated street, institute
Belong to section, geographic number, real estate unit number, ancestor code, element code, the gross area, usable area, Corporate finance rate, etc.
The information such as grade, state, real estate type, purposes, mode, are pocessed information above, can calculate the information of inviting outside investment
Trade and investment promotion index, trade and investment promotion index are used to measure the magnitude of the information of inviting outside investment, and specific computation rule can be by manager according to practical feelings
Condition setting, unrelated with realization of the invention, details are not described herein.
The above-mentioned main interface of trade and investment promotion map system is trade and investment promotion map interface, which includes cartographic information and load on ground
The method of trade and investment promotion mark in figure information, specific information of inviting outside investment mark is as follows:
A: obtaining the display level information of user's selection, preset with current display level according to display level acquisition of information
Map is divided at least two independent sub-districts according to map partition information by the corresponding map partition information of information.
Here display level information can be adjusted by user, general way be map producing zoom in or out by
Button zooms in or out map according to the operation of client, so as to adjust the display level of map.In general, display level is proportional
Ruler embodies, and can also be embodied sometimes using administrative grade, such as city's level-one (the map interface display whole city) or section one
Grade (map interface shows individual sections) etc..In the present embodiment, switching push button is provided, for user's display level different between two
Complicated variant toggles between showing mode.
Specifically, system presets corresponding partition information to different display level information, for example, using scale bar come
When embodying display level, different scale bars corresponds to different partition informations: under the scale bar of 1:400000, systemic presupposition is by ground
Figure is cut into the grid of 10*10, and (scale bar compared to 1:400000, is equivalent to puts at this time under the scale bar of 1:100000
Big map), then map is divided into the grid of 20*20, (grid compared to 10*10, at this time reality corresponding to each grid
Border space becomes smaller, so that so that each grid shared screen space in map interface is almost the same).In another example when using row
Political affairs rank is to embody display level, at the municipal level when, then using the political divisions information of section as partition information, in section
When the display level of level-one, then using the political divisions information of street level-one as partition information.
Map partitioning is then several only according to partition information after according to display level acquisition of information partition information by system
Vertical sub-district.Certainly, so uniform not as good as grid differentiation due to political divisions, the present embodiment is made using political divisions information
To account for whether the ratio value of full map is greater than preset value according to the area for after carrying out subregion, also judging each independent sub-district, if
It is that two subzones then are carried out to the independent sub-district.Two subzones can be to the independent sub-district by the way of grid division, can also
In a manner of using next stage political divisions again.Practical other areas that obtain of the present embodiment account for the ratio value of full map less than default
Then the independent sub-district random division for needing two subzones is several pieces of areas before by the average area of the independent sub-district of value
State the independent sub-district of secondary of average area.
B: it is calculated according to the trade and investment promotion index of all informations of inviting outside investment of each independent sub-district for measuring the whole of the independent sub-district
The whole trade and investment promotion index of body trade and investment promotion situation (such as concentration class, significance level of trade and investment promotion etc.), is every according to the entirety trade and investment promotion index
A independent sub-district configures corresponding display elements;
Specifically, can be using the average value of the trade and investment promotion index of all informations of inviting outside investment of each independent sub-district as the independent son
The whole trade and investment promotion index in area, can also be using the aggregate-value of the trade and investment promotion index of all informations of inviting outside investment of each independent sub-district as this solely
The whole trade and investment promotion index of vertical sub-district, it might even be possible to the whole trade and investment promotion index using the quantity of trade and investment promotion index as the independent sub-district,
Average value, aggregate-value and quantity joint account can also be obtained.The trade and investment promotion map system of the present embodiment provides setting window
It is set according to actual conditions for user.
Display elements are mainly used for embodying the whole trade and investment promotion index of each independent sub-district, and the form of display elements can be more
Sample, as long as there is corresponding mark in map, so as to user's understanding.The present embodiment currently provides two kinds of display elements and supplies
User selects, one is color, variation of the tone for the color of each independent sub-district loaded according to its whole trade and investment promotion index
And it adjusts.The second is display elements are independent sub-district three when map switches to three-dimensional map display pattern (i.e. 3D map)
The height value in map is tieed up, the height value relative to base map of each independent sub-district loaded is according to whole trade and investment promotion index
Change and adjusts.
C: obtaining each independent preset designation strip numerical value of N of sub-district, filters out trade and investment promotion index row top N in the independent sub-district
Information of inviting outside investment, the information of inviting outside investment for arranging top N for the trade and investment promotion index generate mark of promoting trade and investment.
Specifically, N value can be preset fixed value and the mark quantity of all subregions is all consistent.But this reality
If applied in the case that example considers that each subregion is evenly distributed, user just can only be complete to the impression of the concentration class of information of inviting outside investment
Display elements in step B and specific mark of promoting trade and investment is checked, intuitive still not enough by force, therefore present inventor
Think to indicate the concentration class for embodying information of inviting outside investment that quantity still should be appropriate.Therefore, it is recruited according to the entirety of the independent sub-district
Designation strip numerical value of N is arranged in ranking value of quotient's index in all independent sub-districts;It is also contemplated that if using political divisions information
Subregion is carried out, then each independent sub-district different sizes, if designation strip numerical value of N is all equal, the trade and investment promotion of each independent sub-district
The region that the density of mark is inconsistent or even certain trade and investment promotion concentration class are high promote trade and investment instead mark density it is lower, therefore this implementation
Also designation strip numerical value of N is arranged according to the area of the whole trade and investment promotion index of the independent sub-district in example.
In conjunction with above two aspect, the present embodiment designation strip numerical value of N setting steps are as follows: set the area of independent sub-district as M, this is solely
Integrally trade and investment promotion index arranges I position to vertical sub-district in all independent sub-districts, then enables designation strip numerical value of N=M*K1/(I+K2);Wherein,
K1、K2For predetermined coefficient.In order to facilitate the density of the trade and investment promotion mark in user flexibility adjustment interface, the present embodiment is also in map circle
Face generates mark density input port (adjusting horizontal stripe), and is referred to according to the mark density that the mark density input port receives
It enables to adjust K1、K2Numerical value.
In addition, operating for the ease of user to information of inviting outside investment, mark of promoting trade and investment, which has, to be carried out jumping connection, jumps connection
The action bar for showing corresponding information of inviting outside investment for the trade and investment promotion beacon is generated when being triggered, include in the action bar it is newly-increased, nullify,
The function buttons such as modification, plotting, space querying and attribute query.
It should be noted that the method for above-mentioned information of inviting outside investment mark executes the calculating being stored in storage medium by processor
Machine program is realized.
Finally it should be noted that the above embodiments are merely illustrative of the technical solutions of the present invention, rather than the present invention is protected
The limitation of range is protected, although explaining in detail referring to preferred embodiment to the present invention, those skilled in the art are answered
Work as understanding, it can be with modification or equivalent replacement of the technical solution of the present invention are made, without departing from the reality of technical solution of the present invention
