Exporting Flow Arrows and importing into GIS

Hello, 

I have tried looking for an answer on the forum but was unable to find one. While exporting data from the FlexTables as a shape file (.shp), I encounter a problem trying to import it into GIS.

I’m going to need some guidance on how to interpret the Angle field. The QReverses field is all 0. The Angle and QReverses fields cannot be edited in the model afaik. What is displayed is not consistent with the model. 

The issue is that flow arrow directions that are generated using the exported shapefile do not match the flow arrow directions in the water model. The question is how to export the flow directions so that we are able to display them in GIS exactly as the model represents. The angle field provided in the exported shapefile appears to be in Radians but I’m still not able to get the flow arrows pointing in the correct direction.

Please see screenshot below:

Someone please advise on what to do or if one can refer me to the correct place for an answer. 

Thank you.

  • Additionally - I assume you're referring to the use of the flow arrow export option from the pipe flextable mentioned here. Can you provide any background information on why you need to use this? It was originally added in part as a way to help users get hydraulic model information to ArcGIS Pro, but WaterGEMS and SewerGEMS now support integration with ArcGIS Pro. From your screenshot, it appears that you may be using ArcMap. Have you considered integrating WaterGEMS with ArcMap and using the Renderer to display flow arrows?

    Based on my initial research, the "Angle" field is in degrees, with the following assumptions: "The calculated angle of the flow arrow based on the flow direction and geometry of the pipe.  If the calculated angle is < 180, then 180 is added.  If the calculated angle is > 180, then 180 is subtracted.  Using this angle you can determine which way the flow arrow points."

    I will confirm with our developers if this is correct and if there is any other assumptions or information to help with this. (which we can then document in the related Wiki article)
