Extraction of Model Time-series Using Pre-defined XY Points

EFDC_Explorer

Hi,
Is there a convenient way to extract model time-series at specific points within the model domain using a given data file with XY coorindates? The model extraction tool in EE7.2 allows for extraction multiple XY locations for a given time value, but does not seem to allow for extraction of model time-series.
Thanks!

Hi David,

Yes, there is a convenient way to extract time series in EE instead of manually selecting the grid cells each point. Please follow the following instructions.
1. First of all you need to create a cell selection file whose format looks like following:

*  Time Series/Vertical Profile Section Points
	    588508.025	   4512234.175	i=8,j=48
	    587135.775	   4511109.775	i=3,j=48
	    587893.600	   4511450.325	i=9,j=52
	    586942.550	   4510272.325	i=4,j=42
	    587323.000	   4509847.625	i=8,j=35
	    587073.925	   4508903.550	i=5,j=29
	    586965.975	   4507824.050	i=7,j=23
	    586394.425	   4507112.250	i=4,j=18
	    585603.375	   4506783.125	i=6,j=13
	    584403.425	   4506264.000	i=6,j=5

You can create such file by using ALT + O key stroke in the view plan window after you have selected the points while extracting time series. After you press ALT + O the following will appear.

2. After you have the cell selection file then in the View Plan click on “Time Series” button at the top menu and then press ALT + I. which prompts the user to select the file for time series extraction. Make sure to click on time series button before pressing ALT + I.
3. After you select the file, then EE will allow you to choose the time period of time series extraction.

I hope it helps. Please let us know if you have any confusion following these instructions.

Best,
