CHICAGO | Getting lost is getting rarer nowadays, and any yahoo with a keyboard or a GPS device can find precise directions or pinpoint the location of an out-of-town landmark.

Now, drivers hooked on digital maps are looking for more than just streets and turns. They want accurate and up-to-date points of interest such as restaurants, gas stations, hotels, theme parks and more.

For digital mapmakers like Navteq Corp., it's up to road teams like Ann McNeil and Rich Joyce to deliver.

Like luxury-class explorers, the geographic analysts cruise streets and roads in a tech-laden SUV outfitted with a satellite tracking computer, electronic clipboard and rooftop cameras.

"Our customers are wanting more and more information," said McNeil, who has driven hundreds of thousands of miles in a decade at Navteq. "We're expanding all the time."

It's all part of a race with Dutch rival Tele Atlas NV to not only chart the world more accurately but combine the maps with other relevant data.

A pioneer of the digital map business, Navteq produces the maps and software found in automobile navigation systems, portable navigation devices made by Garmin Ltd. and other companies, and Internet map sites like AOL's Mapquest, Google Inc.'s Google Maps and Yahoo Inc.'s Yahoo Maps.

Navteq is the Rand McNally of the 21st century, according to Colorado-based map industry consultant Henry Poirot. And the rapid growth may be just beginning.

Thanks to global positioning systems and recent technology advancements, Navteq is fine-tuning ways to let consumers use a phone or other handheld device to track their dogs, find where to jog in another city, learn how many calories they will burn doing it, learn where the nearest 24-hour gas stations are and see current traffic and weather conditions. Tele Atlas has its own projects under way.

"There's a lot of competition going on," said Thilo Koslowski, an analyst for Gartner Inc. "Both companies are trying to show that their data is better, by being innovative in gathering more detailed information."

The mapping duel heated up this week with the announcement that Tele Atlas agreed to a $2.6 billion acquisition by TomTom NV, the world's largest maker of personal navigation devices.

While that should make the combined European company a more formidable foe, Navteq's stock also soared. Analysts said TomTom's competitors such as Garmin may now go to the Chicago-based company for their maps rather than buy from a rival.

Navteq would like to improve its current share, which already includes most of the Internet mapping market and a split of the handheld device market with Tele Atlas. Its European rival drives the roads, too -- the two companies' teams even sometimes spotting one another covering the same turf.

The biggest threat facing the two competitors in the future may be user-generated map content -- a mapping equivalent of YouTube, as it were.

Google also could be a rival. The Internet search leader is deep into research, development and even acquisitions related to its mapping services, which include Google Earth as well as Google Maps.

Navteq has shown a knack for adapting to changing technology.

The company was born in 1985 as Navigation Technologies, focusing on kiosks at car rental agencies and hotels where patrons could print out directions and maps for chosen addresses. Dutch conglomerate Philips Electronics became its primary investor starting in 1989, a role it held until recently.

The company made $110 million on $582 million in sales last year and posted big gains in both categories in the first quarter. It reports second-quarter results Tuesday.

A pair of acquisitions for a combined $216 million in the past nine months underscore that effort: Traffic.com, which produces live traffic reports for cities around the country, and Map Network, producer of special maps for travel destinations, major hotels and big events like the Super Bowl.

In a swiftly moving business, it's not clear if that will be enough to stave off Tele Atlas and any nascent competitors.

"They're not moving fast enough," said Koslowski. "It's not just a question of acquiring companies like Traffic.com. ... The company needs to focus more on emerging markets."

To map 12 million miles and 69 countries, Navteq has used an estimated 100,000 different sources, from satellite images and aerial photography to maps issued by local governments and commercial companies.

But to Green, the "secret sauce" keeping the company on top of the mapping world is the 700 employees who spend half their work time behind the wheel or in the passenger seat.

"I would say that 80 to 85 percent of the effort that we put into making a digital map is from that very labor-intensive driving that we do," he said. "We cannot find the quality, accuracy or richness of the information from all these other sources unless we go do it our way."
