Embodiment Construction

[0023] The implementation process of the present invention is as figure 1 shown, including the following steps:

[0024] (1) Create the target data layer

[0025] According to the needs of data conversion, construct the target Shp data file, including point, line, area elements and their related data attributes.

[0026] (2) Reading of Inp file and element selection

[0027] By adopting the method of the present invention, the existing Inp file is read, and the Inp file is displayed in a graphic format, which is beneficial to the independent selection of the elements that need to be converted. The present invention adopts multiple selection methods to classify the elements. Complete selection, or partial data selection of a specific element category according to individual needs.

[0028] (3) The data of the Inp file matches the Shp file

[0029] On the basis of (2), the data attributes of the selected pipe network data Inp file elements and the Shp file data structure are...

Abstract

The present invention provides a method for converting an SWMM pipeline network hydraulic model Inp file into a GIS model database Shp file, and the method belongs to the intercrossing field of civil engineering and geographic information engineering technologies. To start from update and management of SWMM model data, the present patent provides a method for converting an Inp file into an Shp file, and in combination with conversion from a GIS database to the Inp file, bidirectional conversion between a GIS and SWMM data is achieved. When data of the existing SWMM hydraulic power model Inp file needs to be updated, the data of a model can be more conveniently updated and used by effectively taking the advantage that the Shp file is easy to be modified and updated, and in combination with conversion from the GIS database to the Inp file, bidirectional conversion between the GIS and the SWMM data is achieved.

Description

technical field [0001] The invention relates to a method for converting an Inp file of a SWMM pipe network hydraulic model to a Shp file of a GIS database, which belongs to a cross field of municipal engineering technology and geographic information engineering technology. Background technique [0002] The drainage pipe network system is an indispensable and important facility in the construction of a modern city and an important part of the city's basic construction. With the construction of large domestic cities and the acceleration of urbanization, the scale of the pipe network continues to expand, and the data update frequency of the pipe network is getting faster and faster. The design of the traditional urban drainage pipe network has shown that it cannot meet the actual needs. There are frequent occurrences of waterlogging. [0003] my country currently adopts the constant uniform flow reasoning formula: Qs = qΨF to calculate the rainwater design flow. The constant ...
