If the data relates to projected values, you can use it for demand projections.Īll exclusively from Cadalyst! When simulating these dynamics in your water distribution model, an accurate representation of system demands is wayergems critical as a precise model of the physical components of the model. The lump-sum area in this case is a manjal feature class that represents meter route areas. You can use various data types with this technique, including future land use, projected population or demand density in polygon form with the polygons based upon traffic analysis zones, census tracts, planning districts or other classifications. The geographic location of the meter in the GIS is not necessarily the point from which water is taken from the system, but it may be the centroid of the land parcel, the centroid of building footprint or a point along the frontage of the building. Sometimes you must use the flow distribution technique to assign manuak water to nodes and when any method that uses customer metering data as opposed to system metering data is implemented. Reproduction in whole or in part is prohibited. Meter aggregation is a polygon-to-point allocation technique watergsms the service areas are contained in a GIS polygon feature class, and the wwtergems nodes are contained in a point feature class. Assigning metered demands to nodes is a point-to-point demand allocation technique, meaning that known point demands customer meters are assigned to network demand points demand nodes.ĭo you use social media - such as Facebook or Twitter updates, YouTube manyal, or discussion forums - for work-related purposes?
