Google introduces historical Street View


It has been a while since I’ve posted, and that is mostly due to my new job! I’m doing research for a transportation modeling team, and my job mostly consists of keeping our network models up to date using GIS and other programs.

Anyway, enough about me. Today Google released an improvement for their maps functionality that makes one aspect of my job so much easier. I’ve been working on a 2010 network model (note that it is now 2014), which means I have to pull roadway information (number of lanes, length, speed limit, etc) from 2010 in order to have an accurate model. Since roadways often change, especially in the downtown area, this is not always an easy task. Until now, I’ve been using Google Earth, which has the ability to view historical satellite imagery. So, until today, I’ve been verifying lane counts from a bird’s-eye perspective. This is not always easy when there’s shadows from tall buildings or trees in the way.

But luckily, now I can use Street View from roughly any time since 2007. That means I can go back to 2010 and view what the roads actually looked like from a human’s-eye perspective (or car’s-eye perspective). This makes things way easier! And better yet, it’s built into Google Maps so I can do it right from my browser.

According to the Google Earth blog,

Activating it is quite simple. While viewing imagery in Street View, simply click the clock in the upper-left part of the screen (as shown in the image above) to choose a different time. Note that this feature is rolling out in stages, and you may not yet have access to it.

Easy peasy. I’m going to be using this a lot from now on.¬†Thanks Google!
