Upon perusing new-ish mapping site MapJack for the first time, I was pretty much blown away. Sure, the site only covers a bizarre coupling of cities right now - San Francisco and Chiang Mai, Thailand - but its imaging technology allows you to enter addresses or points of interest, locate them on high-resolution photographic maps and maneuver right up to the front of buildings, pan left and right, turn in circles, zoom in and out and easily switch to nearby vantage points marked on the maps by blue dots.

I was able to easily read building numbers, street signs and even the friggin’ credit card stickers on the doors of several local businesses. Not bad. It’s a cool tool on so many levels, but for travelers, it offers an easy way to view the area a particular hotel is in or the kinds of shops in a certain neighborhood you’re planning to visit on your next trip. It can also give armchair travelers a candid view of popular tourist destinations like Fisherman’s Wharf in San Francisco or Three Kings Square in Chiang Mai.

I’m not sure how often they update the images, but looking at several spots in San Francisco that I know well, they’re quite current despite not being in real time.

The company is working to make maps of the following destinations available soon:

* Lake Tahoe

* Yosemite National Park

* Pacifica

* Palo Alto

* San Jose

* Las Vegas

One word of caution: make sure you have a few minutes to spare before you start playing around with MapJack. I got sucked in and - bam - there went the morning.
