Remarks
Pipeline is a simplified command interpreter allowing execution of a sequence of operations like:
Base.Say "Start" GIS.Close Layer.Open Result=$src Name=source Path="c:\Samples\Interpolation\temperatures.shp" Layer.CreateGrid Result=$dst Name=grid CS=$src Extent=$src Width=1000 Height=1000 Interpolation.Kriging Source=$src Destination=$dst Field=TEMP Layer.Close Layer=$src Ramp Layer=$dst GIS.FullExtent Layer.CreateVector Result=$cntr Name=contours CS=$dst Extent=$dst ShapeType=Arc Layer.AddField Layer=$cntr Name=NewField Type=Float Width=3 Contour Source=$dst Destination=$cntr Field="NEW FIELD" ContourBase=15 ContourInterval=1 GIS.ZoomToLayer Layer=$cntr GIS.Update Base.Say "Done"
See Pipeline for the list of available operations.
