From the Data Validation Editor the user can edit data graphically (graphical editing area); enter data in the table (tabular data area); have HEC-RTS estimate data values based on surrounding data; and, you can accept questioned or rejected data. When you have finished editing data, you can save (i.e., commit) results back to DSS file(s). Whether editing the data graphically or via the tabular display, HEC-RTS keeps the graphical and tabular areas synchronized as the user navigates and make changes.

Graphical Editing

Edit data graphically by using the graphical editing tools. However, the user cannot execute estimates for acceptable quality data with the graphical editing tools. Editing data graphically can also be accomplished by using the Single Point Edit Tool or the Multi-Point Edit Tool.
To change an existing point with the Single Point Edit Tool : 

  1. From the Data Validation Editor, select the Single Point Edit Tool. The Data Validation Editor needs to be in the edit mode.
  2. From the bottom of the Data Validation Editor, select Edit All Data, for the Options menu, click Edit All Data.
  3. Point to a location in the graphical editing area and double-click, the point becomes a pink triangle.
  4. To move the point, select the Pointer/Selector Tool , click and drag the pink triangle. You will only be able to move the point up and down. As you move the point, the numerical value of the data point will change (see the tabular data area).
  5. When you get the place where you want the point, right-click on the pink triangle. From the shortcut menu, click Accept. The Quality Flag will automatically be set to estimate, and the data will be protected.
  6. A red line will be drawn where the old data value for the point was, and the blue line will connect to the new position of the point.
  7. If you know that the new data value is correct, click  to save the new data value to the selected DSS file.

With the Multi-Point Edit Tool , the user can produce estimates for data along multi-point lines:

  1. From the Data Validation Editor, select the Multi-Point Edit Tool. The Data Validation Editor needs to be in the edit mode.
  2. From the bottom of the Data Validation Editor, select Edit All Data, for the Options menu, click Edit All Data.
  3. Click the mouse where you want multiple new values added along a line. You must move progressively right, moving ahead in time.
  4. At the end of the line, click and then right-click. You will now have a pink triangle wherever you clicked the mouse.
  5. If you are satisfied with the values, click Accept. The Quality Flag will automatically be set to estimate, and the data will be protected.
  6. A red line will be drawn where the old data values were, and the blue line will connect to the new position of the points.
  7. If you know that the new data values are correct, click to save the new data values to the selected DSS file.

Tabular Editing

When the Data Validation Editor opens, you are directly on the first problem data point, if any. In the tabular data area, the Estimate/Entry column allows the modification of numerical data values. When cells in this column display with white backgrounds, data can be edited.

To edit data in the table:

  1. Be sure to put the Data Validation Editor in edit mode, if you need to edit data that is flagged acceptable, from the Options menu (Data Validation Editor), click Edit All Data.
  2. To edit data, enter values in the Estimate/Entry column (data is given a quality flag of keyboard, K), or select a cell and click Estimate (data is given a quality flag of estimate, E), this will create a data value that is based on the surrounding data values.
  3. If satisfied with the values, click Accept. The new data value will display in the Revised column (Figure 1) with a Quality Flag of keyboard (K) or estimate (E), and the data will be protected.Figure 1 Tabular Data Area - Shortcut Menu
  4. A red line will be drawn where the old data values were, and a blue line will connect to the new position of the points.
  5. If the new data values are correct, click  to save the new data values to DSS file(s).

From the tabular data area there is a shortcut menu (Figure 1) that allows the user to set quality flags on data, whether the data is protected or not, and, provides two ways to fill in data values on the table.
Using Fill - Linear:

  1. This will produce a linear interpolation of values between two values in the Estimate/Entry column (Figure 1). 
  2. Enter values in the first and last rows of the range of interest to create two base values (or use Estimate to create the new values).
  3. Select the range of rows, starting with the first base value and ending with the second base value. Select a range of rows either by clicking on a row and dragging, or by clicking one row and then selecting another by holding down the SHIFT key.
  4. Right-click, from the shortcut menu click Fill – Linear (Figure 1). The cells in the Estimate/Entry column of the selected rows will now contain data values produce from a linear interpolation between the two base values.
  5. If satisfied with the values, click Accept. The new data values will appear in the Revised column (Figure 1) with a Quality Flag of keyboard (K) or estimate (E), and the data will be protected.
  6. A red line will be drawn where the old data values were, and a blue line will connect to the new position of the points.
  7. If the new data values are correct, click  to save the new data values to DSS file(s).

Using Fill - Repeat:

  1. This will duplicate the selected value in all the selected cells in the Estimate/Entry column (Figure 1).
  2. Enter a new value in the first row (or use Estimate to create the new value).
  3. Select the range of rows, starting with the base value. Select a range of rows either by clicking on a row and dragging, or by clicking one row and then selecting another by holding down the SHIFT key.
  4. Right-click, from the shortcut menu (Figure 1), click Fill – Repeat. The cells in the Estimate/Entry column of the selected rows will now contain the same value as the data that was entered for the base value.
  5. If satisfied with the values, click Accept and the new data values will appear in the Revised column with a Quality Flag of keyboard (K) or estimate (E), and the data will be protected.
  6. A red line will be drawn where the old data values were, and a blue line will connect to the new position of the points.
  7. If the new data values are correct, click  to save the new data values to DSS file(s).
