Main Window

The main window includes the following:

• Menu bar, with the application menus

• Toolbar on the left side, with buttons for commonly used functions (display controlled by View > Show Toolbar)

• Tool tip area under the menu bar, with information about how to evaluate the displayed data and suggestions about what to do next (display controlled by View > Show Tool Tips)

• Drawing area, showing layers, tiles, and query results

• Legend table, with an entry for each layer, tile, and query result that is displayed in the drawing area

• Current layer information: you can change the current layer, edit the properties of the current layer, and control whether the display is redrawn on every zoom and pan operation

• Status bar at the bottom (display controlled by View > Show Status Bar)

Suggestions: Always display the tool tips (see View > Show Tool Tips). If you want to be warned beforehand about potentially time-consuming operations, deselect the draw without warning feature (View > Draw Without Warning toggle setting).

The displayed objects can be a single indexed layer, two or more indexed layers. or one or more non-indexed layers. The available operations vary depending on the objects displayed.

Zoom and pan operations erase all other layers and queries in the drawing area; therefore, you are often asked to confirm these operations.
