 You can also combine multiple selection techniques. For step-by-step instruc- tions, choose Help Contents, click the Index tab, and look up "selecting map features."    Note If a map includes multiple selectable polygon layers, some selection tech- niques (such as Select Radius, Select Polygon, Select Within, and using the mouse to drag a rectangle around map features) select features from all selectable layers. When selected features on different layers overlap one another, the selection color for each layer varies depending on how many features overlap. Portions of unselected map features also change color if a feature in a layer beneath them is selected. These color changes differentiate the different layers. Creating Buffers around Map Features Online Help Index buffers A common GIS spatial query involves finding all features within a specified distance, or a buffer, of one or more other features. A buffer is a polygon that defines its boundaries at a specified distance from a point, line, or another polygon. For example, you could locate all customers within one mile of a number of store locations. As part of this query, you might also want to see the area that defines the spatial query. Autodesk MapGuide Author can create buffer zones around one or more selected features. You can then select features that fall within these buffers.  You use the View Buffer command to create buffers. For step-by-step  instructions, choose Help Contents, click the Index tab, and look up "buffers." Printing a Map Online Help Index page setup printing maps Although most users work with maps almost exclusively online, it is very useful to be able to print out a map. If you are authoring a map, you might want to print it out, to verify that it looks the way you want it to look, before publishing it online. Or, if you are working with the map to answer specific questions, such as determining the best location for a new store or substation, you might want to print out the map that accompanies a report you generated to present to others on your team. You can customize your printed maps by including a title, a legend, a scale bar, a North arrow, the map's URL, and the current date and time. Also, you can specify the scale of the map you want to print, or you can have MapGuide automatically scale the map to fit the printed page. Creating Buffers around Map Features | 135
