Thread: SCADA Points in GIS

  1. #1

    Question SCADA Points in GIS

    We have a GIS Layer showing the names and locations of the SCADA points in our water utility.

    In InfoWater, would these points be in Junctions or other Feature Class?

    Tim,

    I believe it would depend on the type of data point it represents.

    If you are looking at a "pressure sensor" then this would generally be best to be matched to a junction in InfoWater as these locations are where pressure values are calculated.

    If the sensor represents a tank level value, then generally most people would associate that with a model "Tank" element that is used to represent a storage device that could fill or empty.

    If the SCADA point represents a flow meter, this would generally be associated with a pipe element within a model where flow values are calculated.

    One of the common key goals and tasks in building a model from a GIS would be 1) identifying a unique ID for each element, 2) identifying which GIS elements are actually going to be modeled (as not all need to be included in a water model), 3) For those GIS elements to be modeled, Identifying which of the six model element types you will import the GIS element into (Junctions, Tanks, Reservoirs, Pumps, Valves, and Pipes) and then 4) field mapping the GIS fields to the appropriate model or user defined field. These SCADA measurement locations may have an exact match in the model, or at times may match up with an element close to the measurement location. It really depends a lot on which elements are included in the model which it will be.

    It is often wise to put extra thought into how the model is initially build as this can make it either much easier, or much harder the next time you need to update the model.

    We have a presentation on some key considerations you may wish to keep in mind when trying to build a model 1:1 with the GIS. Please contact us at support@innovyze.com if you would like us to send you a copy.
