DeLorme Street Atlas is a route planning and GPS navigation software program containing street-level map coverage of USA and Canada, and also some main roads and highways in Mexico. Interestingly, the product even includes highway network for quite a lot of other countries all around the world, but the roads disappear when we attempt to zoom a bit closer.
DeLorme has over 30 years long history in the mapping business, and its Street Atlas USA has been around for over 15 years. The same product is now marketed also in Canada under the name of Street Atlas USA/Canada.
DeLorme Street Atlas is an application rich on features. It allows a level of customization users of other programs can only dream about. A brand new user will not master this software over night, just like no one can possibly master Adobe Photoshop in a short time. Yet, even though my previous exposure to Street Atlas was limited to trying it very briefly quite a long time ago, before it even had detailed map of Canada, I still managed to set it up with a surprising ease - within minutes from completing the installation I was already on my way to my destination.
Maps
Unlike many other makers of mapping and GPS navigation products, DeLorme doesn't utilize map data licensed from one of the two major map data providers, Navteq and Tele Atlas. DeLorme makes its own maps. In my opinion, products based on NT or TA data do have an edge at the moment. However, at the time of this writing, both Navteq and Tele Atlas are being sold. In a world without independent map data providers, the idea of a product developer making it's own maps, is becoming increasingly more attractive.
For the most part DeLorme maps are fine, but some 2 lane divided highways are shown just as one line on the map. This may affect routing. In Toronto, Canada, where I drive a lot, Hwy-401 is affected by this lack of detail. Express lanes and collector lanes are both shown on the map as one line. Apparently this doesn't seem to prevent many thousands of loyal SA users from buying a new SA version every year, but I still wish this issue is addressed in the future.
Add your own roads
DeLorme Street Atlas allows users to add new roads to the map. The new roads can be routable. Users can even edit some underlying properties, such as one-way street, two-way street, prohibited right turn, and prohibited left turn. This is a feature which I don't think any other consumer mapping program offers. I suspect the reason for this is that other product developers, who use third party map data from either Navteq or Tele Atlas, would need to pay expensive licensing fees for the privilege to implement such functionality. On the other hand, DeLorme can do anything it wishes with its own map data.
In addition to the current functionality, it would be nice perhaps to let users draw not just local roads, but even major roads, and highway ramps. In my area I noticed a few ramps missing, but I didn't find a way to connect a road, created by me, to a highway.
Driving with DeLorme Street Atlas
While it may be at first a bit overwhelming to see all the tabs and options on the screen, the basic use of the program is actually fairly simple. If you just wish to drive from your current GPS location to your destination, all that you need to do is just type your destination address (as shown above), and hit the Enter-key on your keyboard. A route will be immediately calculated, and you may start driving. The map will show the route, and the voice will guide you by telling you where and when to turn. The voice direction prompts include street names, too.
Customization options
Here in random order I'm going to mention at least a few features users are allowed to customize to suit their own preferences:
* Automatic route recalculation can be turned off. While most users will likely keep this feature on at all times, there are those who will love the ability to turn it off. Especially those who spend quite a while painstakingly planning their route, or drivers of large trucks and RVs, who just cannot afford to leave routing completely up to a computer program.
* Recalculate when off route threshold can be set to any distance you desire;
* Disable screen saver when program is running feature can be turned on or off;
* Edit existing roads (change direction of one-way-streets, or set prohibited turns);
* Keyboard shortcuts - use existing ones, and/or set your own;
* Voice command - control the program by talking to it;
* Start program with or without GPS;
* Turn on or off items on the map you wish to see (or not see), such as waypoint labels, route vias, etc;
* Set minimum and maximum zoom level for automatic zoom feature
Aerial and satellite imagery
DeLorme Street Atlas 2008 offers the ability to view raster imagery (such as aerial and satellite imagery) within the program. This data is available separately from DeLorme and can be purchased via the NetLink tab in the program; however, your purchase of Street Atlas USA 2008 entitles you to $40 worth of free raster data. The aerial and satellite imagery data is not available for Canada at the moment.
DeLorme Street Atlas 2008 PLUS
The "PLUS" version includes everything in the regular version plus extensive data import capability, 150 million U.S. and Canadian phone listings, and higher-end print and draw tools. I think the built-in phone book alone may be well worth the $20 premium for the "Plus" version.
