【正文】 NOTE: Changing a map?s coordinate system only affects how the map is presented to the client. The source data in the SDF files on the Autodesk MapGuide Server must remain in generic decimal Lat/Long coordinates or conform to the predominant projection. The following Map Window Properties dialog box tabs will be discussed in Chapter 5: Reports The Reports tab enables you to create, change or provide access to dynamic reports. Zoom Goto The Zoom Goto tab enables you to specify direct zooming to a selected location on the map. Popup Menu The Popup Menu tab enables you to create or change the popup menu. Popup menus appear in Autodesk MapGuide Viewer map window when you rightclick over the map. Security The Security tab allows you to implement windowbased password protection for a map. A word of caution here: MWF passwords can not be overridden. Should you fet the password embedded in an MWF file, this file will not be recoverable. Always keep a backup copy of your MWF files without passwords in a secure location. You can also leave a tracking ID in the security area where you can track the progress of a particular map.

In order to begin the process of creating a map for an application, you typically start by defining the maximum extents of the map. Then you can determine map layer properties for additional levels of specificity. By zooming into a country so that its geographic boundaries are within the view of the Autodesk MapGuide Author window, you can use Take Center And Size From Current Zoom to center the map within that window. This map is the base on which additional map layers are transposed and overlaid. Coordinate System The Coordinate System tab enables you to specify or change a map39。 Figure : Popup menu amp。 ???

These actions can be defined when customizing the popup menu in Autodesk MapGuide Author. _blank ObjectLinkTarget* Specifies the name of the target window where Autodesk MapGuide Viewer will display the URL associated with a map feature. ObjectLink ReportTarget* Specifies the name of the target window where Autodesk MapGuide Viewer will display reports returned from the View Report popup menu mand. Report ErrorTarget* Specifies the name of the target window where the Autodesk MapGuide Viewer will display the URL of an error or missing page. Error URLList Specifies whether Autodesk MapGuide Viewer should generate an HTML document, which lists the names and links of map objects that have URLs associated with them, when objects are selected. The HTML document is displayed in the URLListTarget window. [ON | OFF] OFF URLListTarget* Specifies the name of the target window where Autodesk MapGuide Viewer will display its URLList when objects are selected. ObjectLink AutoLinkLayers Specifies whether Autodesk MapGuide Viewer should automatically download and display the URLs associated with map objects from the named map layers. The URLs are displayed in the AutoLinkTarget window. AutoLinkTarget* Specifies the name of the target window where Autodesk MapGuide Viewer will display the URLs downloaded with AutoLinkLayers from the named map layers. ObjectLink AutoLinkDelay Specifies the number of seconds before the next URL associated with a map object by AutoLinkLayer will be displayed in the AutoLinkTarget window. If 0 seconds is specified as the delay, the automatic timed update feature will be disabled, and the AutoLinkTarget window will be updated when the mouse passes over a map object on a named map layer with AutoLinkLayers. 20 Chapter 4: Working with Map Layers in Autodesk MapGuide Author 9 Ext If you are using Microsoft Inter Explorer , you must add “amp。 [MI ？？？？ | KM | M | FT] M SelObjs 指定當(dāng)加載 Viewer 和顯示地圖后，選中的地圖特征。這個(gè)設(shè)置會(huì)覆蓋 Width 參數(shù)，如果設(shè)置了此參數(shù)。這個(gè)參數(shù)只有在應(yīng)用了 Lat 和 Lon 參數(shù)時(shí)才有效。這個(gè)參數(shù)只有和 Lat, Lon 和 Units 參數(shù)同時(shí)設(shè)置才有效。該參數(shù)只有在設(shè)置了 Lan 和 Scale 參數(shù)時(shí)才有效，或者在設(shè)置了 Lan, Width 和 Units 參數(shù)時(shí)有效。該參數(shù)只有在設(shè)置了 Lon 和 Scale 參數(shù)時(shí)才有效，或者在設(shè)置了 Lon, Width 和 Units 參數(shù)時(shí)有效。 0 值會(huì)完全隱藏圖例。 [ON | OFF] ON ToolBar 指定是否顯示工具欄。 你可以環(huán)繞一個(gè)城市來(lái)創(chuàng)建一個(gè)緩沖區(qū)，并找到在 1000 英里范圍內(nèi)所有的國(guó)家，然后生成一個(gè)關(guān)于這些國(guó)家空間數(shù)據(jù)報(bào)告。緩沖區(qū)會(huì)在選中特征周?chē)梢粋€(gè)條帶（ zone）或圓（ bubble）狀區(qū)域，通過(guò)這些緩沖區(qū)可以再選擇所需的其它特征。 Select Select Within 選中在一個(gè)制定的地圖特征內(nèi)的所有特征。 Zoom Zoom Out Zoom out from the area defined by a center point.
