and MapCreate Canada, with all mapping categories included. (Size will
vary depending on which package of MapCreate you have.)
In the U.S., Lake Michigan is approximately 26 MB, all of Missouri is 41
MB and the entire state of California is approximately 87 MB. A six-mile-
wide corridor map from San Diego, California to the Maine-Canada border,
following Interstate highways, is about 50 MB.
In Canada, a map of Lake Winnipeg (including the major lakes to the
northwest) is 6.84 MB. All of Saskatchewan is 64 MB, all of British Colum-
bia is 69 MB. A six-mile-wide corridor map from Prince Rupert on the west
coast to Louisbourg on the east coast, following Trans-Canada highways,
is about 35 MB.
Important Notes About Cards and File Size
The size of a Map File is important. It must be small enough to fit on the
MMC (MultiMedia Card) that your GPS uses for data storage. This solid-
state, flash memory device is about the size of a postage stamp.
At press time, the MMCs shipped with the GPS Accessories Pack version
of MapCreate 6.3 are 32 MB size. If you're using a 32 MB MMC, your Map
File must be less than 32 MB in order to fit on the card. (This space issue
is the same as floppy disks; you can't really fit a 1.44 MB file onto a 1.44
MB diskette because some space is required for the disk's file allocation
table. In the case of a 32 MB MMC, actual maximum useable space will be
approximately 29 MB to 30 MB.)
MMCs and SD cards are used in a variety of other digital devices. Most
electronics or digital camera stores sell MMCs and SD cards, and at press
time they are available in 16 MB, 32 MB, 64 MB, 128 MB, 256 MB and 512
MB sizes. Cards with even greater capacity will likely be available in the
future. MapCreate is a powerful tool for your GPS, because it allows you to
match your map's file size and detail level to your card's memory capacity
and your travel needs.
NOTE:
Due to software requirements in the GPS units, MMC or SD cards can
hold a maximum of 32 different files at one time for the Brunton Atlas-
The total amount of information cannot exceed the MMC size capacity,
no matter what the number of files is. For example, an 8 MB MMC in
an Atals could hold approximately one 7.66 MB file, or 32 files, so long
as the 32 files totaled 7.66 MB or less.
Other brands of GPS units use direct serial cable connections to transfer
high detail maps from a computer to the GPS device. Brunton switched
from this traditional method to removable memory cards for several rea-
sons. A USB card reader can transfer a large custom map to your unit 30
times faster than a serial cable connection. Removable media means you
