v7.6 [Sep 28, 2010]
MapViewer 7 introduces three new types of thematic maps - Contour Map, Non-Contiguous Cartogram, and Vector Map.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.
