FAQ: Other Questions
- Q: What software does the Great Circle Mapper use?
- A: The Great Circle Mapper uses primarily custom software, with several third-party libraries and data from many sources. Please see the credits page for details.
- Q: Why not use Google Maps?
- A:
Using Google Maps
would add some features, notably the ability to pan, but would have a
number of downsides:
- The site would be slower. In addition to reducing the utility of the site for experimentation, the speed difference would make it especially painful with slow network links (like smart phones when not using WiFi).
- Fewer browsers would work. Google Maps depends on JavaScript and other browser features. The Great Circle Mapper is designed to work with any graphical browser, though appearance and some features may degrade with less capable browsers or without JavaScript.
- A choice of map projections (such as orthographic maps, including the polar aspects) would not be available with Google Maps.
- Non-web ports of the site would not be possible.
- Simplicity and independence from other sites helps make the Great Circle Mapper more reliable.
- Q: Can I get the source code for the Great Circle Mapper?
- A: No, there are no plans to release the source code.
- Q: How can I buy advertising on the Great Circle Mapper?
- A: Advertising will be offered on the site soon. Please check back for details.
- Q: What browsers does the Great Circle Mapper work with?
- A:
The Great Circle Mapper is intended to support all standards-compliant
web browsers. It has been tested with the following browsers:
- Camino 2.0 (Mac OS X)
- Chrome 3.0 (Mac OS X)
- Firefox 3.5 (Windows/XP, Mac OS X)
- Firefox 3.6 (Windows/XP, Mac OS X)
- Internet Explorer 6 (Windows/XP)
- Internet Explorer 8 (Windows/XP)
- Safari (iPhone)
- Safari 4 (Mac OS X)
There are known problems with Internet Explorer (IE) due to non-compliance with web standards. In IE 6, the map scaling widget is not visible. This problem does not occur in IE 8 though a few minor cosmetic issues remain. IE 7 is believed to display like IE 8 but this has not yet been tested. A fix for the IE 6 problem will be implemented as soon as possible.
