(See page 1-12.) When the window first opens only the New, Theme Wizard, OK, and <br /> Cancel buttons plus the Read Only field are available.All other fields and buttons are unavailable. <br /> The Theme Editor window title bar displays the type of layer chosen on the Display toolbar. <br /> If there are existing themes for the selected layer,the Add,Rename, and Delete buttons plus the <br /> Static checkbox are available when the window first opens. <br /> MapTrak allows you to associate non-geographic information with objects and apply that infor- <br /> mation to objects,for display on the map. This kind of non-geographic information is known as a <br /> theme. You can use themes, such as street speeds,unit information,and boundary information,to <br /> differentiate between various types of the same object and display each type differently on the <br /> map. For instance, if you are displaying schools as an object on the map,you can define a theme <br /> to display elementary schools in blue,middle schools in red, and high schools in green. <br /> Themes do not store any data. They contain a set of criteria(the theme expression)and record the <br /> display configuration for objects matching the criteria. When a theme is applied to an object, <br /> those objects display on the map according to the display configuration defined by the theme. <br /> 1-64 01/06/10 <br />
