The InfoWorks data formats are native and therefore do require access to InfoWorks in order to convert the data. Note, that the following steps can be undertaken with a InfoWorks ICM Viewer licence and a full licence is not currently required.
Although the InfoWorks ICM data formats are proprietry, it is relatively easy to use the Open Data Export Centre within InfoWorks ICM to export the model geometry data to open GIS layer formats (both shapefile and MIF/
To open the Open Data Export Centre in InfoWorks ICM, open your network in the geoplan, select the relevant scenario, and go to '''Network->Export->Using Open

==Quick Export of Geometry Data==
To get a full export of all the model files, with InfoWorks file formats, open the network and go to '''Network->Export->to Shape Files''', select the save location and the InfoWorks tables that you're interested in. Once exported the shape files can be opened in GIS to view the network table geometry and parameters. Once the data is exported, it's possible to
A Ruby script is also available which will export export all data via the Open Data Export Centre without the need for the user to export each table individually. The data can use a config file to undertake some of the mapping of field values and some conversion.
==Use of Ruby Scripts==
It’s possible to utilise the Ruby Scripting interface within InfoWorks ICM to speed up the export. A ruby script can be run to call the Open Data Export Centre, and export all requested tables, using a specified config file automatically, significantly reducing the number of button clicks. An example Ruby Script is available from <u>[https://gitlab.com/tuflow-user-group/tuflow/model-conversions/infoworks-icm TUFLOW Gitlab User Group]</u> which exports all tables and data in an InfoWorks format.
To run the script, you’ll again need to run InfoWorks ICM with a viewer licence or greater. With the desired network in the geoplan, go to '''Network->Run Ruby Script'''. Navigate to and select the ruby script, in the below this is ICM_Out_to_shp_1.rb.

The script will then begin running and prompt the user to select a config file. Navigate and select the relevant config file.

The user will then be prompted where they would like to export the data too. Select an appropriate file directory. The ruby script will then cycle through the list of tables within the script and export the tables automatically. Once complete the script will return a log highlighting the location of the exported files. All network objects are exported regardless of system type. System type is exported as an additional field in the shape files to enable filtering within GIS as required.

The exported shape files can then be opened in GIS for further inspection and once checked can be linked together using the various TUFLOW control files. A set of generic control files for this are in progress.

*Shapefile limitations mean that field names and values can only be 11 characters long. This can mean that some node ids and other information is truncated. This is reported in the error reporting.
