Demo1: Open NEFIS data file
Demo1: Open NEFIS definition file
Demo1: Define ELEMENT: MEAN VELOCITY (3)
Demo1: Define ELEMENT: WATERDEPTH
Demo1: Define CELL: OBSERVATION = MEAN VELOCITY + WATERDEPTH
Demo1: Define GROUP: RIVERDATA = OBSERVATION (100,10)
Demo1: Create space for data labelled: RED RIVER,using THE RIVERDATA GROUP DEFINITION
Demo1: Read observation data from input file (not a NEFIS action)
Demo1: Write the same DATA, but now all cells at ONE go
Demo1: Start retrieval
