Free GPS Software
I took a look at some of the online offers for free GPS software and
found, like many "free" offers there were often limits and provisos
involved. Often the freeware is a scaled--down version of purchasable
products. Sometimes the free product has restricted functionality with
features disabled, other products are trial--based and are disabled after
a certain time (hours or days or use).
An example of limited free GPS software can be found at GPS Utility. The
downloadable freeware is limited 100 waypoints and 500 track points.
(There are 65,000 of each in the registered version of their program.)
The free program gives you a good opportunity to try before you buy, and
this is the benefit of most free programs.
There are online sites that list various free GPS software and describe
how to use the programs after you download them. Often individuals who
have used the programs themselves develop the sites. These are great
because they give you an unbiased interpretation of the benefits and
disadvantages of the programs before you use them.
Using free GPS software you can download programs that allow you to
retrieve and display aerial photos, topographical maps, USGS landmarks.
There are programs available that allow you import scanned images and add
latitude and longitude points and other data.
Free GPS software downloads are available for PDA units that are capable
of communication with GPS receivers. With these downloads you can have a
useful navigation assistant, location database manager, and GPS data
converter.
Programs to manage GPS waypoint and route files are available for both PC
and Mac users. The waypoints and route files can be saved or converted to
various formats used by other mapping programs.
If you need to transfer information to and from your GPS receiver and
your home computer or laptop there are several free programs that allow
you to do so. There are also programs that allow Garmin GPS receivers to
"talk" to one another. Many of the programs listed here are directed at
the hiking/trekker community, but there are also free programs available
for auto GPS systems and marine navigational systems. I found a couple of
marine navigation programs that allow you to download nautical charts and
plotters.
There are free GPS software programs that allow you to download street
maps that might not be included in your auto--navigation system. If you
intend downloading in--vehicle software, make sure that it has audio
capacity, an essential safety factor for motorists. One such program
offers data for several countries with voice guidance in twelve languages.
Free GPS software is also available for downloading to your cell phone.
This is mostly tracking software and can be phone specific. You might
want to check with your carrier before downloading anything to your cell
phone to make sure that it does not incur extra charges.
As satellites are constantly moving, it is helpful to know the optimal
time for data collection in your area. There is free GPS software that
includes an almanac to let you know the availability of satellites at any
given time.
Some of the free GPS software is brand specific. Programs designed for a
Garmin receiver may not work for a Magellan, so check out the
specifications carefully, especially if you intend purchasing a
registered version after your trial period. Other software works with
most brands.
