As the year draws to an end I look forward a brief vacation and then it’s on to a new job. I’m happy to announce I will be joining the engineering team at Pictometry in January. Pictometry is an exciting place to be these days. They are a growing company in a fascinating field. I’m particularly interested because it gives me the opportunity to develop software applications in an area that has been a very long time interest for me. An area where I have not previously had the opportunity to take the deep dive to the extent I believe I will be able to in their shop.

Oblique aerial view of my house from the south
Pictometry creates and provides oblique aerial imagery combined with geospatial data to deliver unique mapping applications to it’s customers. Not sure what that means? Well in plain english here’s how it works. The guys from Pictometry fly their airplanes in a pattern over an area of interest. All the while taking digital pictures of what’s below and storing these images with the geospatial data that represents exactly where the image was taken. Now you may be wondering what makes this different from satellite photos. The difference is that the images are take at an angle instead of straight down. (this is the “oblique” part) And a single location is photographed 4 times from 4 different points of view (east, north, south and west). Finally the images are later combined into large browsable maps.
Pictometry has developed their own software application (Pictometry online) to view this data for their customers. For some examples of what these images look like take a look at the Pictometry Image Gallery. Another way is to browse bing.com. For example follow this link and take a look at the Sydney Opera House. In the upper left you will see some control gadgets. Hover your mouse over “Aerial” then from the drop down menu choose “Birds eye view”. You should now see an what is called an oblique aerial image. You can even rotate the view, north south east and west. Compare this with the other option that gives you a satellite view. A satellite view only gives you an image looking directly down.

The advantages of oblique aerial photography are many including the obvious that you can see the sides of buildings, not just the roof. Another advantage is that we can combine the imagery from 4 different angles give us a rich data set that lets us explore an object of interest in 3 dimensions, and in some cases construct 3D models of an object on the ground.
Another big advantage is the use of oblique aerial photography in public safety and law enforcement. Here’s an interesting story of a man who tracked his stolen iphone using a combination of location based technologies including Apple’s Find My iPhone service and Pictometry images from bing.com to see the location where the phone had been take to.
There are many more potential applications, imagine the possibilities as the number and types of ground imagery increases Just how much of the planet has been mapped with Pictometry’s images? As I understand it today the Majority of US metropolitan regions and more than 1,500 cities around the world have been mapped by Pictometry. It’s an impressive portfolio. Although there are a lot open spaces between cities that are not mapped today this too may change as the application list for what we can do with this technology grows. I’m happy to say I’m really looking forward to being a part of developing these some of these new applications. I think it’s going to be a real challenge and a lot of fun.
