The interval of compass and map left margin is calculated, scale bar size and location is calculated；
Judge whether scale bar exceeds body of a map or chart, if exceeding, then adjusts compass position, that is, recalculate compass
Continue to calculate scale bar size and location with the interval of map left margin, until scale bar left margin is without departing from map；
Draw compass, scale bar；
As shown in figure 8, the treatment process of The Key to Maps is as follows:
Obtain the figure layer of legend to be added；
There are the figure layers of data on acquisition drawing；
Obtain legend template, drawing board configuration；
Obtain the corresponding legend of figure layer name；
According to legend number, the legend configuration met is found from drawing board configuration；
It calculates the size of each legend, position, illustrate font；
It scales, translate each legend to designated position.
Step S5, character property contents processing is carried out, complete drawing decoration is generated.
After the main ornamenting element of ornamenting is completed in processing, it is also necessary to handle the content of some character properties, such as addition mark
Topic, bitmap area, approval information, unit time and signature column etc., generate satisfaction planning and natural resources industry after the completion of processing
The PageLayout for figure demand of being engaged in out.These text informations are all configured by configuration system, and are planned and nature with specific
Resource services are related.Wherein bitmap area is similar with main map property, is auxiliary map, is mainly used for showing the position that case represents
Main permit business graph data and partial graphical index data are added in position, these permit business graph datas are according to industry
Business is different and different；Signature column is mainly configured according to drawing board and the right table physical location of drawing, determines place drawing position, and
Filled out information is determined according to the examination & approval situation of current drawing case.Complete drawing decoration is as shown in figure 9, Figure 10 is a kind of complete system
Figure decoration example.
Step S6, file exports.
The picture for generating preview can be printed first, specifically, in will be all in the complete drawing decoration page layout
Hold and is exported by the file of grid format.
In this step, after generating complete drawing ornamenting PageLayout, all the elements for ornamenting of charting all have been generated
At, the picture for generating Print Preview is carried out in next step, is supplied to the preview that interaction center carries out drawing cosmetic outcome,
PageLayout exports all the elements in page layout, and output is divided into two major classes: 1, based on the file of grid format
Output, such as: JPG, BMP, PGN etc.；2, based on the output of vector format, such as: PDF, SVG, AI.Grid format (AG image text
Part format) output default resolution be 96dpi, vector format map output default resolution be 300dip.
One of requirement of Print Preview needs live preview, higher to rate request, so smaller using data volume at this time
Grid slice of data.And it is not high to the quality requirement of result, so using grid format output such as JPG format.According to user
Paper is selected, output processing is carried out by PageLayout, interaction center is as a result returned to picture file format.
If printed in next step if the picture to Print Preview is satisfied.If dissatisfied to Print Preview,
Because the paper document of final printing is provided to construction unit, quality requirement is higher, is needed at this time by main map
In grid slice of data, i.e., slice service data replaced with vector data, then will completely chart and decorate institute in page layout
There is content to be exported, generates the file for meeting printing precision requirement.In configuration system, by map vector number as unit of scheming
It is associated with according to Map Services (grid slice) by the title of figure, so background service center can easily find vector
Spatial data services device where data, and grid slice of data is replaced one by one.After vector data replaces slice of data,
PageLayout exports all the elements in page layout, the pdf document for meeting printing precision requirement is generated, with printing
The picture process for generating preview is similar, the difference is that being the output based on vector format, is as a result returned with PDF file format
Back to interaction center, repeat no more.
The achievement of traditional software drawing saves in the database in the specific format, needs just look into specific software
See drawing achievement.And this relatively easy realization under WebGIS environment, by passing through in background service center
All the elements in page layout are carried out the output of vector data PDF format by PageLayout, are as a result returned with pdf document format
Back to front end interaction center.
If smaller for drawing range, background service center short processing time, the time for generating PDF is shorter, such phase
To easy to accomplish, but if very big for drawing range, the processing time is more than more than half an hour, if using general
WebService mode carries out background process, can become highly unstable because handling time time-out, or even will appear collapse
Situation.
After the completion of the backstage drawing ornamenting processing of core, the publication serviced by stabilised platform is needed, the present invention
Embodiment is used ArcGIS Server as the platform of service publication and is issued with GP service.Specifically, by compiled
Dll file is registered with Desktop, Server respectively；The GP tool registered is added in ArcCatalog；?
GP tool to be released is run in ArcCatalog, is inputted parameter, is called a GP tool；After GP tool is run successfully, in GP
Tool operation result interface, right button issue GP service；The address of service GP is inputted on webpage, opens GP service page；In webpage
On, parameter is inputted, " Submit Job (GET) " button is clicked, calls GP service；After calling GP service, and webpage is opened, obtained
GP service operation result.
Embodiment two:
Embodiment one describes the realization process of common mapping.But in practical situations in, in many cases item need
Carry out ultralong beltlike drawing.The business scenario that ultralong beltlike drawing is mainly used in overlength and charts on a large scale, such as needs to road
