What's New in MapViewer 4?



Four new exciting map types are available in MapViewer 4, color prism maps, flow maps, line graph maps, and classed pin maps.

Color Prism Maps

Prism maps can now be colored with one of three methods.

  • You can define color classes according to a variable, similar to hatch maps.

  • You can use a color gradation through the prism. The top of the tallest prism has the maximum color and the bottom of the prisms have the minimum color.

  • You can also use the base map fill color for the prisms.

There are also options to white-wash prism walls, control the prism edge color, and change the lighting settings.

Flow Maps

A flow map scales curves (polylines) on the map. The curves are scaled in proportion to the data values represented for each curve. The wider the curve, the greater the data value associated with the curve.

Line Graph Maps

Line graph maps show line graphs of the data on each boundary. By looking at a single line graph, you can see how the individual data value relates to the whole data set.

Classed Pin Maps

Pin maps can now use colors and symbols to represent classes of data for pin location on the map. Categorizing the pins is similar to categorizing data for a hatch map, except the information is point-based rather than area-based. You can control the symbol color and size, the number of bins, and the binning method.

In MapViewer 4, you can edit, rotate, and move each pin label individually!


You can project your map in one of over 25 different projections. Define your own ellipsoid or use one of the predefined ellipsoids. Also, you can specify one of 200+ datums or create a custom datum.


MapViewer 4 supports queries for all map types with any data file type. You can use the Analysis | Query command to select, show, or apply properties to the boundaries that meet the criteria.


MapViewer 4 includes three new organizational managers. The Layer Manager shows all layers and makes them easily accessible. The Object Property Manager allows you to easily view and edit object properties. The Object Data Manager allows you to view and edit the data for an object.


There are two ways to measure distance. Use the Analysis | Measure Distance command to find distance by clicking points on a map. Use the Analysis | Distance of Travel command to find distance between the centroids of selected objects. The distance is reported in a file, and you can show the route of travel on the map.


Map scale bars can have the first cycle divided into components. You can also choose one of several units for your scale bar (centimeters, chains, feet, inches, kilometers, links, meters, miles, millimeters, nautical miles, rods, US feet, or yards).

In addition to the existing Windows stock patterns and bitmap patterns, we have included a new vector pattern editor in MapViewer 4. You can use one of the existing vector patterns or create your own patterns. The vector patterns can be scaled, so clear pattern printing is possible on any resolution printer or plotter!


MapViewer 4 can import and export most geographical file types. You can import many file types such as USGS SDTS Topological Vector Files [.DDF], ESRI Shapefiles [.SHP], ESRI ArcInfo Export Format [.E00], and MapInfo Interchange Format [.MIF]. With the availability of digital boundaries on the web and digital boundaries for resale, you can now take advantage of these newly added import types!

Other new formats include GS Interchange [.GSI], Enhanced Windows Metafile [.EMF], and Portable Network Graphics [.PNG].


There are several reports available in MapViewer through the View | Reports command. These reports provide information about the data of an object, about the contents of the Object Property Manager, about centroids, and about the entire map.


  • Hatch maps can have circles or squares.
  • Designed for Windows 2000, NT4, Me, 98, and 95.
  • The help menu contains options for reporting problems, suggestions, and to ask for information.
  • Use the Help | Check for Updates command to check for and install updates.
  • You can now break a curve.
  • Added a change file button to map dialogs so that you can keep your map settings but use different data.
  • Use map limits to show only part of your map.
  • Updated dialog boxes so that it is easier to add and remove variables from pie, bar, and post dialog boxes.
  • The map automatically updates when the data file is changed.
  • The program is double precision all around.
  • We have added buffer analysis. This feature allows you to create a buffer around points, curves, and areas. Once the buffer is created, you can look at the data within the buffer zone using the Analysis menu commands.
  • Added several new toolbars and added tools to existing toolbars. The toolbars are dockable and can be floating.
  • New symbols sets have been added.
