In this exercise, we'll load in some high resolution visible imagery from the GINI East 1km dataset.
When loading a high resolution satellite imagery with the Adaptive Resolution turned on,
the IDV calculates the resolution of
the view window, sets the magnification factors dynamically, and loads a sufficient amount
of the data to generate an image at the correct resolution. With the Match Display Region
option turned on, a rubber band box (RBB) interface allows the user to zoom in/out or change the
projection, forcing the IDV to recalculate the magnification factors and get higher/lower
resolution data. This feature improves the IDV memory usage and performance significantly.
The Adaptive Resolution is a property in the User Preference. It can also be set in
the Projections drop down menu of main view window. If a display has been created without
the Adaptive Resolution turned on, it can be changed by selecting the option
under View→Match Display Region drop down menu in the same display control.
