| About | -----------------
--------
These options are briefly explained below :
File
----
The "File" menu allows you to open or close a database, export
the current view as a PostScript file, quit the application, or
display the "about" box.
"Open" The purpose of the "Open" option is to allow you to
pick a database for map display. On clicking on the "Open"
option in the "File" menu, a dialog box comes up with a
scrollable list of .MAP files and the directories in the
current directory. You can select the database by navigating
through the file system by clicking on the entries in the
list. After selecting the desired database, you can click
on the "Open" button in the dialog menu, or click on
"Cancel" if the desired database is not found. After you
click "Open" in the dialog box, the demo program will open
the specified database and display a small region of the map
at the lowest level of detail. You can change the map region
and the level of detail in the displayed map using various
other options described below.
"Close" will close the current database.
"Export" will export the current view of the map to a
PostScript file whose name you specify. This file can be
downloaded to a PostScript compatible printer. It is not
currently compatible with draw or paint programs that
manipulate PostScript files.
"Quit" will quit the application.
"About" gives the version and copyright information about
the MapDemo program.
Copy
----
The "Edit" option of the "Copy" menu allows you to copy a bitmap
representation of the current map view to the windows clipboard.
You may then "Paste" that bitmap into another application, such
as windows paint.
Mouse
-----
The "Mouse" menu allows you to set the function of the mouse
cursor to any of Center map, Zoom in, Zoom out, or Nearest
feature. Note that when the map is drawn, not every feature
displayed will be labeled, depending on the density of the
features.
"Zoom In" allows you to zoom in on a region of the map. To
do this, click on the "Zoom In" option in the "Mouse" menu.
The mouse cursor will change to a crosshair. Follow this by
positioning the cursor at the upper left corner of the
region of interest. Keeping the left mouse button down,
drag the cursor to the lower right corner of the region of
interest. Release the mouse button and a zoomed in view of
the map will be displayed. The displayed map is centered at
the center of the zoom box. The map is scaled such that the
height of the map region in the zoom box fits into the
display window. The width is adjusted somewhat to fit the
display window.
"Zoom out" allows you to zoom out a region of the map. To
do this, click on the "Zoom Out" option in the "Display"
menu. The mouse cursor will change to a crosshair. Now
position the cursor at the upper left corner of the zoom
box. Keeping the left mouse button down, drag the cursor to
the lower right corner of the region of interest. Release
the mouse button, a zoomed out view of the map will be
displayed. The displayed map is centered at the center of
the zoom box. In the case of Zoom In, the height of the map
region enclosed by the zoom box is expanded to fit the
display window. In the case of Zoom Out, the currently
displayed map region is scaled so that height of the current
map can fit into the display area with height equal to that
of the zoom box.
"Center map" allows you to change the center point of the
map, effectively letting you pan across the map. When you
select this option, the mouse cursor will change to a
diagonal arrow. This is the default state of the mouse
cursor when a map is first loaded.
"Nearest feature" allows you to click on the map and see the
name of the nearest feature (point or line) in the message
window below the map. When you select this option, the
mouse cursor will change to a vertical arrow.
Display
-------
The "Display" menu lets you redraw the screen, overlay a center
cross marker on the screen, or geocode (find the location of) an
address.
"Refresh" will redraw the current map view.
"Geocode address" will bring up a dialog box asking for the
various elements of an address. Press the tab key to move
between fields in this dialog box. You do not need to fill
in all parts of an address for the Geocoding function to
work. If there are multiple matches for your input, you
will be asked to select one from a list. Once you geocode
to a location, the map scale zooms in to at least 1.2 miles.
The location is marked by a 'pushpin' which will continue to
display while you zoom or re-center the map.
Try geocoding to
Number: 1600
Street: pennsylvania
or to
Number: (press tab)
Street: (lincoln memorial)
"Include center cross" will, if selected, display a cross
at the center of the map after it is drawn.
