Overview

 

 

While browsing the map, users may have no idea about the current browsing location after map is zoomed in or out or so. Thus, the "Overview Window" function can be used to help users to recognize the current browsing position and direction. Firstly click "Window" on the main menu and select "Overview Window." "Overview" window shows up on the map window. The "Overview Extent" on the "Overview" window represents the current browsing extent; when browsing extent moves, the "Overview Extent" changes along. Similarly, if you drag the "Overview Extent" with mouse, the browsing extent on the map window changes along.

 

     

 

 

Meanwhile, right-clicking the "Overview" window and clicking "Properties" will show the "Overview Properties." Here you can set the reference layer to display on "Overview" window, background color and extent symbol.

 

　 　　

 

 

Besides, opening multiple Overview windows at a time is supported, allowing viewing and manipulating the map based on different requirements.
