CoastWatch Data Analysis Tool Help: Using the data view toolbar
You can use the toolbar buttons to change the data displayed
using a point-and-click interface on the data view. Each tool
modifies the data view in a different way:
Magnify
- Magnifies the data view features by two times so that a smaller
area of the earth is shown in the view.
Shrink
- Shrinks the data view features by two times so that a larger
area of the earth is shown in the view.
Actual
- Sets the view magnification so that each data pixel is exactly
one screen pixel in size.
Zoom
- Allows you to select a rectangular area of interest on the
data view. The view is magnified to encompass the new zoom
rectangle.
Pan
- Allows you to click and drag the data view to a new area
without changing the magnification.
Recenter
- Allows you to select a new data view center location,
similar to panning but with a single click.
Fit
- Resets the data view magnification and eliminates any black
edges, so that the full extent of the view is used. Some of the
data may be cropped at the edges in order to accomplish the
fit.
Reset
- Resets the data view magnification so that the entire extent of
the data is shown.
