If you weren’t sure about switching to an Android phone in the near future, this might put you over the edge. Google Maps Navigation is an absolutely killer app. And it is only available for Android 2.0 phones.

Today is Droid day, and for the most part Google is taking a backseat and letting their partners get most of the attention. But Droid is the first Android phone to run Android 2.0, and Google Maps Navigation is clearly the early trophy app for those devices.

Since its inception, Google Maps has always rolling out little tweaks and new features that are useful. But today comes the first large-scale overhaul of the look and feel of the service in quite a while. But you may not even notice it.

The reason is that almost all of the changes are very subtle. And unless you spend hours looking at Google Maps everyday, you probably aren’t going to realize when a road outline has been toned down, for example. But looking at the side-by-side images, it’s clear to see that the new look is much nice. Gone is much of the clutter cause by darkened street outlines.

Google Maps been steadily crowdsourcing information from users and authoritative sources that who can share detailed information about the changes in the physical world, such as new roads, water bodies and more. Because of this flux of information, Google has released a new base map dataset.

Thanks to info from both the USDA’s Forest Services and the US Geological Survey, Google has made a significant update to its maps, adding more detail about water bodies, parks, roads and more. For example, with the new data sat, you can now zoom in on roadways to figure out how large a road is. And Google has added in-depth info on locations like college campuses and bike trails.

Last night, I was out with some friends in search of a particular bar. Naturally, we did the 21st century equivalent of asking a gas station attendant for directions, we pulled out our iPhones to look it up in the Maps application. The result was odd; the bar we were looking for was there, but there was another result in the same spot, labeled as “User-created content.”

Yesterday, Search Engine Land noted that sponsored links (ads) are starting to show up in the Maps application on the iPhone. It would appear that Google is slowly adding some new features. But what’s odd is that these features are showing up without warning, and, as far as I can tell, without a way to turn them off.

One of the original goals of Google has always been to help people find the information they are looking for and get out of the way as fast as possible. It was a point of pride, and in fact a design principle, to get people off the search results page to other places on the Internet. Yahoo was the site that tried to keep you from ever leaving, Google was the opposite.

Well, it was easier to send people away when Google was just a search engine. Now it has apps and Gmail and Google Maps and Google Books, and a lot of other reasons to stick around on Google itself. But there is still a clear demarcation between its content/communication sites and search. At least there was until late last week when it launched Google Places on Google Maps. Google Places is a local search page for restaurants and other local businesses that brings together the address, phone number, Website, maps, description, directions, photos and reviews all on one page.

When you click on a pin for a local business or place of interest on Google Maps a bubble will open up, and if you click “more info” sometimes it will take you to the Google Places page. So far, so good. Google Places is simply making Google Maps better, right?

The concerns arise, however, back on Google’s main search page, where Google is indexing these Places pages. Since Google controls its own search index, it can push Google Places more prominently if it so desires. There isn’t a heck of a lot of evidence that Google is doing this yet, but the mere fact that Google is indexing these Places pages has the SEO world in a tizzy.

Increasingly these days you hear the words “Google” and “monopoly” in the same sentence. There is no shortage of fears that the search giant is getting too powerful in the search and online advertising space. But today, the two words are being joined for an entirely different reason: The board game Monopoly is about to launch an online version with Google Maps.

All the details aren’t clear yet, as the game won’t launch until September 9. But it would appear that Hasbro, makers of the Monopoly game, is attempting to turn the franchise into a massively multi-player online game. Called “Monopoly City Streets,” here’s a brief description that is offered on the teaser site:

The goal is simple. Play to beat your friends and the world to become the richest property magnate in existence.

Any one who commutes in major cities knows the value of back roads when it comes to avoiding traffic on the highways during peak rush hour times. Google Maps just added a nifty feature that will show you live traffic conditions on arterial roads (non-highway roads) in selected cities. Google Maps will also show traffic patterns on main highways as well, helping you see what the least-trafficked route is for your commute.

When you zoom-in on the city you’re interested in and click the “Traffic” button in the upper-right corner of the map, you’ll see the traffic conditions of both arterial roads and highways. The colors correspond to the speed of traffic green is little to no traffic, yellow is medium congestion, red is heavy congestion, and red/black is stop-and-go traffic.

As an online free mapping service, Google Maps is a great product. But it’s lacking in certain parts of the world. And rather than pay people to go get information about those places, Google has smartly been using a service called Map Maker, which lets locals and people knowledgeable about the area edit it themselves. And this week, Google has added a couple important areas to the list: Mexico and Eastern Europe.

“These two launches have doubled the number of users who can map their country on Map Maker,” Google notes today. That’s impressive, but even more impressive is the full list of countries that can now use Map Maker to improve local maps. And while Map Maker doesn’t work in places like the U.S. and other well mapped-out areas of the world, you can edit things on U.S. maps such as place locations. It seems clear that Google Maps is a wiki of sorts now, meaning the community is responsible for a lot of the data on it.

Slowly but surely, Google Maps is filling up with more and more places. If you do a search in a major city, you are likely to find landmarks, museums, famous stores and restaurants labeled right on the map even if you did not specifically search for them.

If you pull up a map of midtown Manhattan, for example, you’ll see museums like MOMA and the American Folk Art Museum, as well as tourist attractions like the “Tree at Rockefeller Center.” But some of the famous buildings are also marked, like the Sony Building, the Trump Tower, and the CBS building. Churches and chocolate stores show up as well.

Which countries are the worst greenhouse gas emitters? Now you can see for yourself on this handy Google Map created by a department of the UN and Google. The map shows changes in greenhouse gas emissions from 1990 to 2006. Green is good (a decrease in emissions) and purple is bad (an increase).

So who are the worst offenders? Topping the list is Sweden! The country has managed to increase its emissions by 110 percent over that time period. So much for Nordic purity. Following Sweden is Turkey (with a 103 percent increase) and Canada (with a 55 percent increase). Yes, Canada. What is it with these northern countries?

Google Maps is an incredibly useful tool for searching for pretty much anything in a specific geographic area, but I used to find it annoying that I would have to conduct multiple, separate searches in Google Maps for various items along a route or point of interest. Now Google has added a feature that lets you conduct multiple searches within one search for directions.

This feature lets you add visual layers to a particular map as you add more search parameters. So let’s say you are searching for a particular route to get from one destination to another. You can now search for several restaurants and bars within that route. As you conduct multiple searches, you’ll see a blue bar at the bottom of the left side of the Maps page. You can click on it to expand the widget, which will list the searches that you have made. You can also turn searches on or off by clicking on the box to the side of each search. And each search is color coded, so you know which is which.

You know the Google Maps upside-down teardrop shaped markers? It looks like they’re starting to appear in the real world, at various locations around the globe. You can see the locations that have them on this Google Maps Favorite Places page.

For example, there are apparently a bunch of these markers in San Francisco already. One (which happens to be in my neighborhood) has been caught on camera. As you can see, San Francisco Mayor Gavin Newsom has his own Google Maps marker indicating that he likes La Boulange de Polk, a restaurant in the area. Newsom’s marker features a painting of the Golden Gate Bridge, other famous people have their own markers.

With many of us using smartphones with GPS now, we’re starting to take for granted applications like Google Maps being able to pinpoint us. But using computer is a different story. Sure, there have been plugins, and things like Google Toolbar, but those are things that most people aren’t going to bother to install. But starting today, location is now built in to Google Maps in the browser — provided you’re using the right browser.

If you are using either Google Chrome 2.0+ or Mozilla FireFox 3.5+, you’ll now notice a little dot in the upper left-hand corner of Maps, just above the Street View guy. If you click that dot, Google Maps will show you your location on the map. It does this using the W3C Geolocation API standard, according to Google.

I don’t know about you, but when I look at an online map and see outlines of buildings, I get a little frustrated. I want to be able to click somewhere, and find out exactly what’s there. And with a new feature in Google Maps, you can do just that.

If you right-click somewhere on the map, it will bring up a menu with a bunch of options. The new last option allows you to select “What’s here?” And if Google knows — which it does for a lot of places — it will pop up information about what is actually at the location you’re pointing at. If it knows the name of say, a store that is there, it will give that to you. Otherwise, it will give you the address of where you are pointing.

Moving around in Google Street View is not always intuitive. You always end up clicking aimlessly a few times before you can really figure out how to move about. Well, now navigating within Street View is easier thanks to the “pancake.” Google is adding a useful tool called the “pancake” to Street View on Google Maps that lets you travel to a new point within a photo panorama by double clicking on the place or object you would like to see. Google says that it has been able to accomplish this by making a compact representation of the building facade and road geometry for all the Street View panoramas. As you move your mouse within Street View, you’ll see the pancake, which you can move up and down a street and then click on a restaurant, road, building or object nearby. The pancake is shown as a circle on roads and a rectangle when following the facade of a building.

Sometimes there are many ways to get from point A to point B, whether you are walking or driving. Until now, Google Maps’ directions feature has given you the route they consider the best and allows you to drag and drop the route to change your path. Today, Google Maps is adding functionality that suggests additional routes so that you can see all of them on the map for comparison.

Under a “Suggested Routes” heading, you will now be able to access other routes to the same destination. This is a feature that GPS systems in car, like a Garmin device, have been offering for quite some time so it makes sense that Google would want to catch up. Google says that they choose alternative routes bases on many factors, including distance, travel time, and number of turns. Google Maps boils this data down to what is the lowest “cost” and ranks the routes based upon the “cost.”

Henry Hudson never did find the Northwest passage to India, but this year marks the 400th anniversary of his third voyage—the one where he came to New York and sailed up what is now the Hudson River (he made it as far as modern-day Albany). Hudson showed that often it is what you stumble upon on your way to somewhere else that turns out to be your great discovery. To celebrate the anniversary, the Henry Hudson 400 Foundation has charted all of Hudson’s voyages onto a Google map, along with overlays of historical maps. The overlays are kind of clunky, but just being able to see the actual routes Hudson took is kind of cool.

I only wish the custom map was available on the Google Maps site itself (maybe it is, but I wasn’t able to find it, although I did find this map of Hudson’s third voyage which was put together by an elementary school class). In fact, Google Maps should have an “Explorers section” where you could see famous expedition routes from Lewis and Clark’s to Shackleton’s voyage to Antarctica. Many of these have already been mapped out for Google Earth or as custom Google Maps, but it would be nice to have them all in one place as a section within Google Maps, or at least make Google could make them easier to find.

Update: Tragically, one of the skiers, Rob Williams, was not able to be saved. Our thoughts go out to his family.

Yesterday, a group of technology entrepreneurs from the UK on a skiing vacation in the Swiss Alps (Verbier) lost two of their party around 4 PM CET. Other members of the group put out a request on Twitter in order to learn the numbers of their mobile phones, so they could use the signals to track them down.

According to follow-up tweets, one person (Jason) was rescued using a combination of GPS, Google Maps to determine longitude and latitude, and the signals returned from his iPhone, but another one (Rob) was still missing as the two had apparently been split up. It’s been 7 to 10 hours since the last Twitter messages at this point, so unfortunately we can only hope and not confirm if Rob has been found by now.

Below are a number of screenshots with Twitter messages from some of the group.

Transit planner HopStop launched its free iPhone application last week to rival the mobile version of Google Map’s Transit option. The application, with support from iPhone’s GPS functionality, offers all the same services as the website. This includes trip customization, maps marked with nearby subways and bus stops, a taxi mode that estimates time and cost of travel and contact information for taxi companies, and the ability to re-route transit plan provided.

In the past, Hopstop was ahead of competitor Google Transit in terms of providing transit info for a widespread amount of metropolitan areas but Google has caught up (and maybe surpassed) with its Maps-based transit planner. And Google Maps is integrated with iPhone 3G’s GPS, making Google Transit a free native application that doesn’t have to be downloaded.

Can you name Google’s top ten products? If you look at how Quantcast ranks Google’s subdomains, you can get a sense of which Google products are the most popular, since they each have their own subdomain. Google’s main search engine tops the list with an estimated 136.6 million unique visitors in the U.S. Then comes Google Maps (36 million), Image Search (31.7 million), and Gmail (10.5 million). Google Docs, Sites, and Knol are still too small to make the top-ten, but are all showing decent growth.

YouTube and Orkut are not included below because they are on their own domains, but YouTube would be second with 70 million unique visitors. Orkut is not popular in the U.S., so it would not be a factor in this particular list. And I took out sorry.google.com, the domain Google uses to try to catch bots and spyware. It would have ranked No. 8.
