Posting updates about Google Maps satellite imagery in the Fresno region used to be a frequent topic on this blog. Thanks to the lack of clouds for half the year, Fresno was lucky in that new images were posted about twice a year, compared to some more populated area that only got an update every other year – or even less frequently. Basically, to provide the images, a satellite has to take hundreds of pictures, and then they are all blended together automatically to reveal a seamless image without clouds in the way. Since Fresno has so many clear days, it’s much easier to get the shots.
The California High Speed Rail Authority have recently posted aerial shots of the various construction sites that are well underway in the California Central Valley, primarily around Fresno. They tend to post updates on their official Flickr account once or twice a month, but most are taken at ground level. Since the Google Earth satellite images are unfortunately over 2-year old at this point, these new photos, taken last week, provide a unique vantage point. Seeing the action from above, you can really understand the scale of the various bridges, and make sense of how they fit in.
