4.1.1 Plan Views of Gridded Data

Plan views are horizontal displays of two dimensional data. These data can be true 2D fields (e.g., sea level pressure) or a slice of a 3D dataset at a constant pressure or height (e.g., 500 hPa heights). The IDV can display these plan views as contours, color filled contours, or color shaded displays.

  1. First, let's create a display of contours of sea level pressure.
  2. Now, let's add a display of color-filled contours of precipitation.

  4. Overlay contours of 500 hPa geopotential height on the same display.
