Technical solution in order to preferably explain the present invention will be described in detail below by one embodiment.
To complete urban and rural planning data interaction, the dwg format space data under existing CAD platform is needed (to take out by ETL
The processes such as take, clear up, loading) means, lossless is transformed into the library GIS；Simultaneously also to meet the library GIS to CAD platform data
Revolution.According to GIS database design requirement, the characteristics of analyzing and summarize layout data, lossless data conversion template is established.Cause
The urban and rural planning data interaction of this present embodiment uses the Manufacturing resource technology based on semantic conversion and realizes CAD platform and GIS
Two-way " lossless conversion " (as shown in Figure 4) of database.
It mainly include multiple GIS numbers in the rule of OpenGIS, this model when constructing Data Translation model
According to.In entire model, between the data model and data model by difference, OpenGIS between analysis data format
Relationship, in either any data format, " data channel " can smoothly be set up.So either between data format
Conversion or data model between conversion, the phenomenon that being all not easy active data out.CAD and GIS data can be
On the basis of FME data transformation engine, mapping relations corresponding with itself are found.The appearance of mapping relations, not only solves
Contradiction between the mathematical logic occurred in data conversion, the also conflict in solution data mode surface level, to realize CAD
Data conversion between GIS.
As shown in figure 5, the semantic conversion under Auto CAD platform, to reach the interoperability between two platform datas.Specifically
Conversion plan is as follows:
An element, according to unique block name, is recombinated each after being broken up when block name (block_name) is not empty
Discrete point, line, surface or note elements, and be stored in Geodatabase, it is executed and is produced in the form of inserting block (block)；
For line feature, by calling the profiles information such as line width, line color in Geodatabase data attribute list
Carry out automatic conversion；
Face element in Geodatabase data, when its fill area attribute is not sky, using filling (hatch) pattern and
The Fill Color of script is converted, and when fill area attribute is empty, then it is converted with polygon；
For note elements, according in attribute list rotation angle, semantic conversion is carried out to its mode etc.；
Graphic layer structure after reverting to Auto CAD data for guarantee is almost the same, during semantic conversion, using figure
Layer name is fanned out to.
Since OpenGIS allows user to reconfigure data in data conversion process, user can be special according to its
Demand, extracts the different level and content of same data source, rather than input data in a single format.The space number that OGC is proposed
According to standard semantic, the master pattern of spatial data semanteme, including space semantic model, attribute semantemes model, coordinate system are defined
Semantic model, and standard semantic rule is given based on GML.Semantic conversion be based on the Conversion of Spatial Data on semantic hierarchies,
It is other than the conversion of data structure, it is often more important that conversion and operation to semantic data model.(as shown in Figure 6)
For example same engine of semantic conversion not only can be to input data but also can be right by element operating language
Output data carries out redefining for data, and conversion process is as shown above.Because rich there are one in the behind of semantic conversion
Rich Data Translation model, it has internal consistency and external scalability.
Semantic conversion is then different from conventional conversion in many aspects.From overall effect, supplier can be greatly reduced
With workload needed for user, and the administration fee of related data can be reduced.
The main points of semantic conversion are as follows:
Define the mapping between A target and B target；
User element handles language；
Allow to redefine data model, as geometrical relationship 1 to geometrical relationship 2, geometrical relationship to object oriented, towards
Object type 1 is to object oriented 2；
Function is provided to realize lookup, statistics and computing function；
Offer process is used for original data processing into the data of required type.
Whether input or output data, semantic conversion provide an engine (with a kind of language), can be again
Define data.The basis of engine is a data model abundant, keeps internal consistency and scalability.Input/output lattice
The data model of formula or system is mapped to the engine model and does not need using minimum common standard.This engine provides a systems
Column method come carry out model to model bi-directional conversion.Which ensure that respective system can be used in data set provider and data consumer
Platform unite without being restricted.
Automation, the mass processing of data are also realized in this implementation using space ETL technology.ETL is data pick-up, conversion
It is the pass that data warehouse obtains quality data with the English abbreviation of loading (extract, transformation, loading)
Key link is the process that the available data in each operation system is extracted, converts, cleans and loaded, and urban planning library can
To be considered as a subset of Spatial Data Warehouse, implementation step is as shown in Figure 7.
As shown in figure 8, space ETL will not only handle conventional attribute data, while also needing to handle magnanimity, multi-time Scales
, multiple dimensioned spatial data.In Fundamental Geographic Information Database construction production process, multiple processes are related to turning for data
The operation such as change, reconstruct, merging.Spatial ETL (Extraction, the Transformation and provided using ArcGIS
Loading is extracted, converts and is loaded) automation of these operations may be implemented for tool and mass executes, and it is by many years
Research has mature technical products, support up to hundreds of source data format, support between hundreds of spatial coordinate systems
Conversion, while its Spatial Semantics based on FME maps principle, provides data semantic conversion customization, supports with backstage service mode
It runs and can be integrated with relevant technology systems, it is different for solving the isomery assimilation in data production between data with different source data
The problems such as lossless conversion between multi-scale data, realizes automation, the mass processing of data.
When layout data needs interact under different platform, pass through semantic conversion and space ETL technology, Neng Gougen
According to user demand flexibly, quickly customize Data Translation model, complete lossless conversion of the data between different platform, and then improve
Production efficiency reduces artificial rough error, and then Improving The Quality of Products.
Space ETL includes data pick-up, conversion and loads 3 processes, realizes provincial normal address Ku Hui based on space ETL
Collecting process is specifically as shown in Figure 9.
