Zoom in Map Views
Zooming the map adjusts the detail of the geographic data that is shown on the map.
Zooming in from a country level might show state and city details. Zooming out from a street-level view might show cities but not street-level information. For master-detail linking, the map view focuses on the detail feature that was selected in the master view.
You can zoom in various ways:
-
Click on the map background. To zoom by clicking, you must first select the zoom mode from the toolbar. The default mode is pan, which is indicated by a hand cursor. When you’re in zoom mode, the mouse pointer changes to a magnifying glass and you can click-zoom directly on the map itself.
When you’re zooming in, you can either single-click or click and drag to use marquee zoom. You can draw a box that delineates the area in which you want to zoom.
-
Hover over a region of the map to display an information window for that region for the data that is directly below the cursor.
-
Click to zoom in and out. When you click, the map zooms in one "increment" using the click location as the center point.
Zooming and drilling aren’t synonymous. When you zoom, no drill is performed (that is, no new query is issued). However, if you drill on a map layer, that drill likely results in a new zoom level being displayed, if a new layer is added to the map. If a new layer isn’t added, then the zoom level doesn’t change.
You can zoom using either the buttons on the toolbar or the zoom slider. When you use the zoom slider, you zoom in or out of the map as it’s currently displayed. When you hover over the zoom slider, the names of the map layers are displayed beside their mid-range zoom level. Click the names to zoom the map to that level. When you zoom, a new query isn’t issued.
