Fixing Missing Data

When a span of data is missing (no data points exist), you can use
the Fix Missing tool to replace the points by creating a straight-line
interpolation of the missing data points. However, for most
locations, interpolated data is rarely valid for periods of more than a
few hours.

1. Verify the Active data entity from the Active Entity drop-

down list.

2. Select the missing data span using the Fix Missing toolbar

button to display the Fix Missing Data dialog, or click and
drag a selection box around the missing data time span. This
selected span should include the last existing data point before
the missing data gap and the first existing data point after the
missing data gap.

3. Select a data-averaging interval from the Interval drop-down

list for which you want to recreate points. For example,
selecting 15 minutes would create four individual data points
for each hour of missing data. Select the interval that matches
the existing data.

4. Select OK to generate and display the interpolated data.

The interpolated data will display in purple, indicating it is
modified data.
