Map Features

Formats

These historical maps are provided in SVG format. SVG (Scalable Vector Graphics) is a format that is Interactive, Scalable, and allows Zooming and Panning. An SVG enabled browser or viewer plugin is required, we recommend using Opera (see our help file for more information).

Interactive Popup Information
On the SVG historical maps, moving over the name of any country will display a popup with additional information about the country. Note: this feature currently only works in the Opera web browser.

Zooming and Panning

The SVG historical maps allow you to zoom in and out. Once zoomed in, you can pan (move the map around) to any position. Note: this feature is not fully developed in any current web browser.

Colors
All historical maps are 32 bit true color image files. They will display reasonably well for systems set to 16 bit high color displays, but they will display poorly on systems with 8 bit, 256 color settings.

Size
The SVG maps are completely scalable. They will expand or contract to fill the currently active window.
