I was looking through the Google Maps directory recently and found a variety of maps worth checking out. From up-to-date weather to barbershops, they should all be added to your list of Google Maps modules.
Barbershops: The map's description says "Barbershops are one of the last bastions of manliness today." And that's why the developer created a map providing locations to barbershops all over the U.S. Not every area is covered, but if you live in a major city, you'll find at least one or two barbershops to try out.
Best Nightclubs and Bars: If you want to find the best nighttime hangouts in major cities like New York; Scottsdale, Ariz.; or Las Vegas, the Best Nightclubs and Bars Map is for you. After picking an individual city to get a listing of hot spots, you should find all the places you're looking for. It would be nice if it supported more cities, though.
Chandra X-Ray Observatory: The Chandra X-Ray Observatory map gives you in-depth information about Harvard's Chandra X-Ray lab. It has dozens of markers around the world. Each time you click on a map marker, it explains exactly why the location is important to Chandra's operation. If you're interested in space and you want to learn more, this map is for you.
Current Air Quality: Those who have breathing problems will be happy to know that there is a Current Air Quality map that updates each hour with information gathered from government air quality sites. It only tracks the U.S., the U.K., and China, so if you live anywhere else, this probably won't do you much good. But I find it quite useful for where I live.
Distance Measurement Tool: Ever wanted to know what the distance is between Hoboken, N.J., and Tokyo? With the help of the Distance Measurement Tool, you can do just that. Simply click on one spot on the map, then click on another. The tool will show two markers and the distance.
Flickr Mapplet: It's not perfect, but the Flickr Mapplet is a neat addition to your Google Maps favorites. You can search for any kind of image. Once it finds photos that match your query, they will be indicated on the map with markers based on where the photographer claims the photos were taken. Once you click on the marker, you can view the pictures. Its search could be better, but it's still an interesting way to see photos.
Follow the Rainbow: If you want to go to Ireland, Follow the Rainbow is for you. It provides you with all the top spots for history, food, art, and music. When you click one of the markers (they're all color-coded, thus the "Rainbow" name), it tells you where it's located in the country, what it offers, and how to get there.… Read more
