3.7.9 Objective Analysis of Point Data
The IDV can create gridded data fields from point data using Barnes Objective Analysis.
- Leave the metar.csv point data source from the prior exercise.
- In the Field Selector open the "Gridded Fields" tab. This lists the numeric fields in the data.
- Choose "T" and create a
Contour Plan View display.
- In the
Grid Parameters tab check off Use Default and change the number of
passes to 6 and create another Contour Plan View display.
- Toggle the visibility to compare the differences.
- Create a
Point Data Plot display and change its Layout Model to "Temperature" and compare the values to
the grid values.
- Change other values and create display to see what effect they have on
the resulting grid.
