What's New in MapViewer
New Map Types
MapViewer 7 introduces three new types
of thematic maps - Contour Map, Non-Contiguous Cartogram, and Vector
MapViewer can take discrete data measurements, interpolate between
them to create a uniform grid, and then display a contour map
showing lines of constant values. You have complete control over
the appearance of the contour map and can easily limit the
contours to your area of interest.
Cartograms represent data values by changing the size of the
associated area object. In addition to the existing Dorling
cartogram, MapViewer 7 can now create a non-contiguous cartogram,
where the original shapes are retained but resized according to
their data values. Cartograms are particularly useful when there
is an inverse relationship between area and the data value. They
emphasize the areas with the greater data values.
Like a contour map, a vector map also interpolates from discrete
data measurements to create a uniform grid. It then displays
arrows that indicate the direction and magnitude of the steepest
slopes across the grid. You can control the frequency and
appearance of the arrows.
An inset is a display frame that is
positioned on a portion of the page. One or more layers can be
assigned to be displayed within an inset. Objects within an inset
retain their original coordinates even as the inset frame is moved on
the page. The display within the inset frame can be zoomed and panned.
Besides using an inset to enlarge a
portion of a map to show more detail, insets can also be used to:
- Show an overview of the whole map when a portion of the map is
- Apply limits to one or more layers while other layers remain
- Move/resize Alaska and Hawaii in a 50-state map without changing
- Show multiple thematic maps on different parts of the page while
maintaining the original coordinates.
City/State Pin Maps
Making a pin map to show US city
locations is easier than ever! Besides the ability to make pin maps
from X,Y coordinates or from ZIP codes, MapViewer 7 can now make a pin
map based just on city and state names.
Pie Map Enhancements
Pie maps are more versatile than ever!
The radius of each slice can be varied instead of or in addition to
varying the slice percentage. You have your choice of pie shapes to
most effectively display your data.
Print Preview for
When your map fits on a single page,
MapViewer has always had a print preview capability because of showing
the page outline around the map. For the case where your map is larger
than the page, MapViewer 7 adds a print preview for tiled printing.
You can see how the map will be divided between pages and can choose
exactly which tiles to print.
The buffer tool in MapViewer 7 has been
enhanced to allow a negative buffer distance. You can create a buffer
zone inside of an area to show a setback distance.
