System Requirements For Reasonable Use

Windows 95 / 98 / NT / 2000 / ME / XP / XP Pro / Vista / Windows 7 (all trademarks of Microsoft)
at least 200 megabytes free disk space
256 megabytes RAM (All Topo will run in less), 1 GB recommended for BigTopo, BigTopo7 and BigTopo9
Graphics Card / Monitor set to 256 colors or more (True or High Color is better)
600 x 800 Monitor Resolution (1024 x 768 or higher is better)
Mouse, CD ROM drive...

Note, we no longer test new builds of All Topo Maps with Win95, Win98, WinNT, Win2K, WinME.

Optional

GPS and Interface Cable - [ compatible GPS devices ]

Absolute Minimum Requirements

All Topo Maps will run well on a 486 class machine with 16 megabytes of RAM and 100 Megabytes of free disk space. It is a slow experience, but you should be used to it - everything on a 486 runs slowly these days. A couple of warnings: while All Topo Maps will install into 100 megabytes of free disk space, you may not have enough space left to print or export a map!

Notes

The BigTopo seaming tool really uses memory! If you are going to use BigTopo often, we highly recommend at least 1 GB of RAM. Since it is possible to generate very large output files, you will need lots of free disk space. A single BigTopo can fill 250,000,000 bytes!
