Map Controls
The maps can be controlled using a variety of methods, including the traditional push-button zooming, which drills in/out while keeping the map exactly centered. Also, holding down the left mouse button enables you to drag and zoom, left-to-right, across the map, and moving the mouse in the same manner but in the opposite direction zooms out.

DeLorme employs several powerful search capabilities within the software. The first is a simple box called QuickSearch where you type common requests including towns, cities, lat/lons, ZIP codes, street addresses, colleges, and many more to receive the quickest possible matches. The places-of-interest search offers more advanced parameters and the advanced search is used when locating exact matches requires additional customer input.

Add MapNotes; draw your own circles, polygons, and squares; measure the area of your draw objects--even draw in your own roads and route on them--these are amazingly powerful draw tools for the money.

The Phone tab along the bottom portion of the interface allows you to create custom searches for finding either residential or business phone numbers and locations. You can search by yellow-page heading and find all the diesel repair shops and then select only the ones you'd like to display on the map. You can use the phone listings in conjunction with the XData tab to create and save custom data files for frequent retrieval.

Right-click on the map to learn more about what's underneath your cursor. Lat/Lon, names of streets and bodies of water--even local radio station information--can be viewed in this manner. Moreover, the bottom toolbar of the software displays a continuously updated readout of what's underneath your cursor.

The voice tab of the software is where you train the software to recognize your voice for issuing routing and GPS commands while tracking. Ask common questions such as "How far to my next turn?" and the software answers. Microphone recommended for optimal usage. The software also reads upcoming turn information, including the time to turn, time to finish, and name of the street to turn onto. New voice settings allow you to select how far in advance of your turn you'd like to be prompted. Voice can also be turned off if you prefer.

Netlink and Aerial Imagery
NetLink is your online link to DeLorme for free aerial imagery now included with the Street Atlas USA 2007 versions. Select your areas of interest and download only those grids to the software. Toggle the imagery on and off in a single-screen view. Add notes and draw objects to the imagery to customize lifelike views from space.


Pocket PC, Windows Mobile 5.0, and Palm OS Compatible
Included at no extra charge is the DeLorme Handheld software, which now includes support for Windows Mobile 5.0 devices. Access the maps you want from the desktop software and hot-sync to your PDA. Add a DeLorme Bluetooth GPS for use with Bluetooth PDAs and navigate wire-free.

The DeLorme handheld functionality provides address-to-address routing, spoken directions, mobile map colors to reduce in-vehicle glare, and four million places of interest. Finding what you need is easy using the powerful search capabilities. Now you have powerful desktop mapping software and PDA software all conveniently provided in one Street Atlas USA 2007 package.

Maps on iPods
Using a tool similar to how MapShare works, now you can select the maps you want from the desktop software and send them to your photo-capable iPod. These map images are static (e.g., cannot be manipulated once on the iPod) and come across in the order you select them, same as with photos. Once on your device, you can access the ones you need, when you need them. Due to the small screen size of iPods, we recommend these maps for urban walking situations where you can discretely reference the maps you need. (Not GPS compatible.)


E-Z Nav Toolbar
First introduced within the 2006 version of the software, this handy toolbar runs along the top of the interface and offers access to commonly needed routing and GPS options, especially useful for in-vehicle navigation on a laptop PC with the Earthmate GPS. New in the 2007 version -- right-click on the top toolbar and select the various icons you want.

Keyboard Shortcuts
Set your own keyboard shortcut preferences for optimum control when using GPS. The key-bindings function is very powerful and advanced so you can design your ideal in-vehicle navigation solution to your personal specifications.

Right-Click Routing
The easiest way for many to create and alter routes is to use the right-click feature. Select the route on your map and add new stops or vias, delete the route, all by simply right-clicking the object of interest. You can also add your own MapNotes or view the many pre-populated tags provided by the software.


Create automatic routes using the quickest (time) or shortest (distance) routes. Add VIAs to force the routing to take the roads you prefer. Turn on one-way indicators; select major areas to avoid; or select roads based on driving speed preferences. Add Stops and reorganize their order and the routing automatically recalculates. Create and manage routes either in the Route tab or by right-clicking on the maps.

Add Local Roads to Routing
A DeLorme exclusive, this is the best way to update local roads when new developments are planned or added between DeLorme software releases. This tool is located within the Draw tab and lets you draw in the road segment, connecting it to another local road within the database. Assign a name, save it, and when you create automatic routes, the software is smart enough to include these new local roads in the routing calculations and also update the directions.

Personalized Routing with Address Book
Create and save commonly-used names for places you visit often, such as "home," work," or "Dad's." Once these names are assigned, the routing Starts, Stops, and Finishes also display these names making retrieval easy for repeated usage. Customize routes using your own names and save them within MapShare for others to see -- they'll be amazed. You can also include up to 200 names from your address book to be recognized using this system.


The XData Import Wizard is the key to viewing your own data on the map, automatically placed. Easily import your own data from ACT!, Goldmine , Excel, text files, or databases. Select different symbols to represent the locations of your information. Or, create your own custom symbols to use on the map; any 24x24-pixel bitmap image can be easily added as a draw symbol using the intuitive XSym module. Street Atlas USA 2007 Plus best matches your records with a specific address, ZIP code, or latitude/longitude coordinate on the map. NEW tools allow you to symbolize the level of accuracy of your geocoded data.

  • Quickly and easily view the location of each record with a mouse click
  • Add lines, shapes, and text to mark a sales territory or a property boundary
  • Highlight a region to show the untapped market and sales potential
  • Use symbols to mark different accounts or your competition
  • See the city streets and surrounding population centers near your customer locations
  • View concentrations of customers or accounts in specific geographic regions
  • Find new accounts or customers by seeing your business in a new geographic light


Map Data
Because all DeLorme map data is created, updated annually, and owned by DeLorme, we are able to provide many features typically reserved for expensive in-vehicle navigation systems. Free from the license restrictions and third-party dependencies of other publishers, we can also evaluate customer-submitted revisions and implement these changes after triple-checking all submissions. We currently have an enhanced commitment with staff in place to make as many customer revisions as possible.

Places of Interest (POI) Data
The DeLorme database contains over 4 million annually updated places of interest across the U.S., with additional ones in Canada, including restaurants, lodgings, gas stations, travel services, RV stops, malls, shopping--just about everything you could ever need on the road. The software settings let you choose the magnification level to display the various POIs to avoid cluttering your map views. The POIs can be accessed using the many Find capabilities or by right-clicking on the map and selecting places based on type and distance from map center.


GPS Radar Search
Now you can travel with GPS and have the software find upcoming travel services based on their location from you. Find gas, hotels, shopping, and much more in your direction of travel and then easily make detours to these desired stops along the way. It's like having your personal travel concierge with you at all times.

Automatic Back-on-Track GPS
Using the Earthmate GPS LT-20, which turns a laptop PC into a powerful GPS navigator, it's possible to have the software offer new spoken and visual directions when you stray off course. Within the GPS tab of the Options section of the E-Z Nav toolbar, you can select or type the off-route distances you want to travel before the automatic recalculations kick in. Select short distances for city travel and longer ones for highway travel where you may exit frequently for roadside travel services.

GPS Spoken Directions
The software can offer voice directions indicating upcoming turns and street names. It also can be set up to respond to your voice and answer common travel questions--a very powerful capability for mapping software within this price category. Several different voice types are included.


Print crisp color or black & white maps that you control to best match what is seen on screen. Also print Travel Packages containing strip maps and directions to bring on your trip. Don't want to use a lot of ink and paper? Then print just the Turn Details which show thumbnail maps of each of the decision points along your route.

MapShare makes it easy to share your customized maps and directions with family, friends, and business associates. You create exactly the content you want and then post within our online MapShare library, which includes private administrative tools for you to manage. Similar to some of the better online photo resources, MapShare allows you to provide controlled access to your important maps without worrying about email and spam filters.

Demos & Tutorials

Getting Started Tutorial
This tutorial provides a guided tour of the main capabilities of the software. It is also included within the software along with a comprehensive Help section with links to online discussion groups where DeLorme customers can help you.


Street Atlas USA 2007 Plus contains the DeLorme produced and managed United States and now also Canadian street-level network. The included 4 million U.S. places of interest (POIs) are updated annually based on phone book information and DeLorme's own research into exit services. Canadian POIs are also included, many with phone numbers. When you factor in the 120 million included phone listings for the U.S. and Canada, you have one of the most extensive POI databases available anywhere.

Street Atlas USA 2007 Plus DVD allows you to import your own data from text, Excel, Outlook, and other sources. It does not, however, allow 3rd-party supplementary data to be imported.

Verified Purchase
The DeLorme Street Atlas Plus installed without problems. I am impressed that it covers the USA and Canada. I am very happy with it.

I set up the Earthmate BT-20 GPS with my Palm TX handheld unit. It was easy to set up as long as the Palm TX unit Bluetooth detected the BT-20. The BT-20 and the Palm TX unit worked fine together. The only problem I encountered was that the Palm TX unit display was not very easy to see in the daylight. I also wish the BT-20 GPS unit had more information in the little manual with it.

1.0 out of 5 stars DeLorme GPS June 18, 2007
I have used DeLorme maps and a GPS device for years and have been well satisfied with their quality. So, it was with some anticipation that I purchased the Earthmate BT-20 with the Street Atlas USA Plus 2007. The map software worked quite well as usual. However, the Earthmate BT-20 was not compatible with my Treo 650 with Palm OS or my desk top PC. A lengthy discussion with a DeLorme Tech did not resolve the issue. Also, a review of the GPS forum showed that others were having similar problems.
The Earthmate BT-20 may work on other devices. But, I would do a lot more research before purchase.

4.0 out of 5 stars Ok for the price May 27, 2007
By Sam
This is a very functional product. It takes a while to learn to use well and the map data or the GPS accuracy are sometimes limited (it often shows you are traveling next to the road and not on it. No problems using with windows XP laptop and Dell Axim. Overall a good value, but you get what you pay for.
