Create network using shape and csv files

The fist thing we have to do is declare where the shape and csv files are located :

rootPath = r"D:\Workshop\data"

Then we continue with creating the basic network (consisting of branches and nodes) using the "network_Branches.shp" shape file. For this we will need to use a library called "SOBEKTutorialLibrary" in the "Libraries" folder of the toolbox. This is done by adding the following line (and running it).

from Libraries.SOBEKTutorialLibrary import *

This will make all the functions (because of the *) in the "SOBEKTutorialLibrary" library available for use. All these functions will now also appear in the code completion dialog (when you use ctrl + space).

In this library we have a function called "CreateNetworkFromBranchShapeFile" which we will use to create the basic network.

network = CreateNetworkFromBranchShapeFile(rootPath + r"\network_Branches.shp")

After running this line the network will be created using the shape file and added to the variable "network" (if you to see how the network is created in more detail you can look at the CreateNetworkFromBranchShapeFile function in the SOBEKTutorialLibrary.py file in the libraries folder).

Now that we have a network with branches and nodes we can continue with the import of the cross-sections. This is done with the function "AddCrossSectionsToNetwork"

AddCrossSectionsToNetwork(rootPath + r"\network_Cross Sections.shp", rootPath + r"\CrossSectionProfiles.csv", network)

And AddBridgesToNetwork for bridges

AddBridgesToNetwork(rootPath + r"\network_Bridges.shp", rootPath + r"\BridgeProfiles.csv", network)

For the laterals and weirs we use the function :

AddBranchObjectsFromShapeFile(BranchObjectType.LateralSource, rootPath + r"\network_Lateral Sources.shp", network)
AddBranchObjectsFromShapeFile(BranchObjectType.Weir , rootPath + r"\network_Weirs.shp", network)
