Using the applet buttons
These are the buttons at the extreme top of the applet (just below the horizontal line):
Rubberband-box zooming Do a rubberband box (down, drag, and release a mouse button) on any local map; the next map will be on the selected box. At the present, you can't zoom when on the ' view from space' index map. You can also do advanced zooming, like doing an initial zoom image on one of poles, rubberbanding from one side to the other of the initial global map, or using a URL extension to obtain an initial zoom map.
Click-on-a-point panning Click on a single point on any local map to "pan" to a new location: the center of the new map will be at the point you clicked on (i.e. don't draw a box — or this will be interpreted as a zoom). The size of the new region will be the same as the current region — just recentered. Panning on the initial global map just recenters the new map on the (nearest degree) longitude selected; the central latitude will remain the equator in this case. Just like with zooming, at present you can't pan when on the ' view from space' index map.
Initiating the next map request
Generally any action except changing features initiates the next map request. For example,
just do a zoom or pan on the current local map.
If changing features, select and deselect until you get the features list you want.
If after changing features you want the same scale and same type of map (local or index)
that is now being displayed,
click the [Redraw] applet button. This is the
only situation where clicking the [Redraw] is necessary.
Or (cases where your don't click [Redraw]):
Trust us, it's far simplier than it sounds. But if you want to be walked through an example, see the Tutorial.
When you have initiated any map request, the message:
will appear directly under the applet buttons and above the current map. Also, on Netscape and Internet Explorer, the message at the bottom of the browser
means that your map request is being processed; please be patient. When your map is ready, the message under the applet buttons will be your list of selected features, and the message at the bottom of the browser will be something like
At this point the next map image should begin loading and being displayed on the browser.
(Note: If you get a message under the apple buttons:
or a message at the bottom of the browser like: "Local map creation failed ", please report the situation to us.)
Reporting problems First, check the common user errors and known map image problems. If your situation isn't covered there, then go to the bottom of the interactive Voyager page (just below the applet map area) where your session user ID and our email addresses are located. Send us an email describing the problem and exactly what you were doing. Be sure to include your full user ID. We'll look into it.
