Description
Technical Field
The invention relates to a one-picture modeling processing method for urban municipal drainage pipelines based on ArcGIS + InfoWorks ICM, belonging to the crossing field of municipal engineering information technology and geographic information system technology.
Background
The drainage pipe network system is an important urban infrastructure, is used for collecting and conveying urban sewage and runoff generated by urban rainfall and snow melting, has the double functions of protecting the environment and reducing urban disasters, is called as a life line and a blood vessel of a city, and has a non-negligible role in urban planning and construction. It is clear in the new edition of the design Specification for outdoor drainage (GB 50014-2006) (2016 edition) that when the catchment area exceeds 2km 2 When it is used, a mathematical model method is preferably used. It can be seen that the application of the drainage and waterlogging prevention model has been brought up to date.
The 'one picture' of the municipal drainage pipeline is a municipal drainage pipeline information system reflecting the latest current situation of a city and the sustainable dynamic update of planning results, and is an important component part of 'one picture' of the planning territory. The 'one picture' of the municipal drainage pipeline consists of two parts of current drainage pipeline data and planning drainage pipeline data, for example, the 'one picture' of the municipal drainage pipeline in Shenzhen city is based on the surveying data of the current drainage pipeline in Shenzhen city, and the planning pipeline data is integrated on the basis of the newly compiled and approved special planning, the municipal engineering technical files in the legal drawing and the like. The municipal drainage pipeline 'one map' stores drainage pipeline information in a Shapfile format of an ArcGIS database, and the information comprises information of QSDM (initial ground elevation), MDDM (terminal ground elevation), QSBG (initial pipe bottom elevation), MDBG (terminal pipe bottom elevation), PD (gradient), LEN (pipe length), WIDTH (pipe diameter (WIDTH)), HEITH (height), LX (flow direction) and the like of the pipeline, but the municipal drainage pipeline 'one map' does not independently build a node information database, does not contain pipe network topological structure information, cannot be directly applied to the construction of a drainage pipe network model, and still needs to effectively convert drainage pipe network model data.
The ArcGIS is a comprehensive system, and a user can collect, organize, manage, analyze, communicate and publish geographic information by using the ArcGIS, along with the development of computer technology, the unique advantages of the ArcGIS in the aspect of establishing a geospatial database are increasingly prominent, and the ArcGIS is more and more applied to the modeling of a drainage pipe network model and a drainage waterlogging prevention model. The ArcGIS can be applied to data management and spatial analysis, and can also be intuitively and dynamically subjected to modeling or visual management. The ArcGIS data is stored in the form of points, lines and planes, has uniform data form and convenient management, can express the space distribution condition and the geometric condition of the graph and record the attribute data of the graph. When the drainage pipe network model is built, the ArcGIS model database can be conveniently input into the model software system, and with the development of the drainage pipe network model technology, how to effectively build the ArcGIS drainage pipe network model database is very important. The InfoWorks ICM (urban comprehensive drainage basin model system) is one of mainstream drainage pipe network models and sponge urban model software which are widely applied at home and abroad at present, and has flexible data interfaces in the aspect of model data processing, including ArcGIS, CAD, Excel and the like. When the ArcGIS line layer data is imported, the InfoWorks ICM can automatically generate point layer data at two ends of the line layer data without field matching, and automatically numbers the point layer data, initially constructs a pipe network topological relation, provides certain convenience for conversion of model data, but still needs further processing on a pipe network topological structure and pipe network attribute data.
In order to realize the effective conversion from the one-picture information of the municipal drainage pipeline to the drainage pipeline model data, the invention starts from the requirement of the drainage pipeline model construction, based on the storage characteristic of the one-picture information of the municipal drainage pipeline, carries out the automatic conversion of the pipeline model graphic data and the construction of the topological relation of the pipeline network through the InfoWorks ICM, and carries out the processing of the pipeline attribute data and the automatic conversion of the node attribute data through the ArcGIS, thereby realizing the automatic and batch input of the model data, improving the working efficiency of the data conversion, ensuring the quality of the drainage pipeline model data and further effectively improving the quality of the drainage pipeline model construction.
