Contour Map

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.

Non-Contiguous Cartogram

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.

Vector Map

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 enlarged.
  • Apply limits to one or more layers while other layers remain unlimited.
  • Move/resize Alaska and Hawaii in a 50-state map without changing their coordinates.
  • 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 Tiled Printing
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.

Negative Buffer Distances

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.
