30m, the size of displacement and direction are controlled with shifting circle, and displacement circle is using characteristic point as the center of circle, and radius is the circle of 10~30m
Target.Radius size can be adjusted according to the attribute ratings (such as data precision) of target where characteristic point.
After carrying out geometric accuracy Weakening treatment to second processing data, graphic feature passivation (folding is carried out to obtained data
Line song) process may is that broken line segment figure becoming smooth curve, graphic feature is measured from 30 °~150 ° of angle
It is transformed into so that radius of curvature is 5~10m and measures.Passivation is generally used in combination with displacement, is mainly used in corner characteristic point
Generalization processing, this feature point is first shifted, is then passivated further according to corner graphic characteristics.
The data of broken line Qu Huahou carry out spatial relationship repairing again, the repairing of spatial relationship be after repairing characteristic point displacement with
The original topological relation of adjacent target.The displacement of single features point inevitably results in spatial relationship and clashes.For example, for edge
The current road in river side, after the characteristic point displacement of road, the correlated characteristic in river must also shift accordingly, in order to avoid produce
The mistake of raw road " crossing the river ".Client 01 can be closed according to the topological structure of characteristic point after displacement and the topology of adjacent characteristic point
System, repairs characteristic point topological relation, guarantees the continuity of data.

The spatial data of coordinate precision carries out coordinate conversion.Specifically, can realize sky according to following step 2071~step 2073
Between data coordinate conversion:
Step 2071: determining segmentation position.
When client 01 carries out coordinate conversion to spatial data, the original coordinates of the oil-gas pipeline data of load are first determined
It is segmented position, i.e. regional location of the original coordinates within the scope of preset coordinate identical with the original coordinates type.In this hair
In bright embodiment, " the Xi'an 80- the earth 2000 " type selected according to user, the type of original coordinates is just 80 coordinate of Xi'an
System.
Step 2072: determining conversion parameter.
Client 01 has determined that fragment bit postpones, and is determined according to the segmentation position and selected coordinate translation type corresponding
Conversion parameter can determine corresponding 7 parameters in embodiments of the present invention, be respectively: the translation in three directions of coordinate system
Parameter, Δ X, Δ Y and Δ Z, the rotation parameter in three directions of coordinate system, εX、εYAnd εZ, dimensional variation parameter m.
Step 2073: coordinate conversion is carried out to spatial data.
After client 01 determines conversion parameter, according to the conversion parameter and preset coordinate transformation rule to spatial data
Carry out coordinate conversion.Specifically, preset coordinate transformation rule can be indicated with following formula:
Wherein, X1、Y1And Z1For the original coordinates of spatial data, X2、Y2And Z2For the coordinate after conversion.In this way, will calculate
Obtained coordinate replaces original 80 coordinate of Xi'an, can complete the DecryptDecryption of spatial data.
So far, can obtain DecryptDecryption data (including image data carry out coordinate conversion after data and spatial data into
Data after the conversion of row coordinate).
It should be noted that image data carry out can be with spatial data with conversion process and scale bar enhanced processing
Coordinate translation process carry out simultaneously.
Step 208: publication data.
After client 01 obtains DecryptDecryption data, by the DecryptDecryption data publication to network server 02.
Specifically, user can be with the save location of setting DecryptDecryption data in the output data option at interface shown in Fig. 8, In
After obtaining DecryptDecryption data, which can will be saved as map document (the entitled .mxd of suffix) by client 01, be stored in
In the save location of setting.When needing to issue the DecryptDecryption data, client 01 can be called in arcgisserver
CreateGISServerConnectionFile method connects network server 02, then will using CreateMapSDDraft
Map document is converted to service definition rough draft (format sddraft), then uses arcpy.StageService_server
Service definition rough draft (file of sddraft format) is converted to service definition file (file of sd format) by () function, finally
Service definition file is uploaded into network server using arcpy.UploadServiceDefinition_server () function
02, complete the publication of DecryptDecryption data.
Step 209: data investigation.
Client 01 simultaneously folds the Internet map information loaded by Amap API and the DecryptDecryption data
The stack result for adding, and being shown on its display interface.
Step 210: spatial analysis.
When client 01 detects user in the display interface to the stack result of Internet map information and DecryptDecryption data
When the spatial analysis operation of progress, corresponding spatial analysis is determined according to the spatial analysis operation as a result, and showing the space
Analyze result.
Specifically, the Esri geometry api that client 01 calls Arcgis to provide realizes the spatial analysis of map, tool
