What's New in 9.3.1
Take a look at the new features and tools you can use with ArcGIS Desktop 9.3.1.
Temporal Symbology
Temporal, or time-based, symbology lets you alter the display of data based on age, showing time progression.
- The time window sets the interval of data to be rendered.
- Point symbols can be modified by color, symbol, and size, based on age of data and user preferences. Line and polygon symbols can be modified by color.
- Track lines can be drawn to connect observations belonging to the same object.
- Within a track, the current position of an object can be rendered using different symbology.
Time progression, in this case showing paths of commercial aircraft, is rendered using color.
