![]() ![]() If we see a large shopping mall, we can guess it is probably located in the suburbs of a city. Because the sun synchronous satellites that are used take images approximately at solar noon, the shadow extends due north, which means we can determine the orientation of the image. For example, we might refer to a feature like a large parking lot with two large buildings standing next to each other as a clue to narrow down the location. We have only our own eyes to search with, relying on place names and geographical knowledge. ![]() ――How do you identify the location? Do you use some special digital tools? Once they’ve been identified, we adjust the aspect ratio, orientation and distortion of the images so that they overlap exactly with the actual locations, and then map and release them through the digital globe platform Cesium. What our team is working on is locating and identifying on Google Earth the detailed locations of the distributed satellite imagery. The only things we recognize are the names of places like the city Mariupol. Such images are circulated around the world through online articles and social media, but they do not provide detailed location data, making it difficult to pinpoint the precise spot in Ukraine that they represent. Would you tell us more about this project?Ĭompanies like Maxar Technologies and BlackSky release distinctive images culled from the imagery collected by their proprietary satellites. ――The Satellite Images Map of Ukraine website you launched collects and maps satellite imagery of damage shot from the skies above Ukraine. The site also includes an image of a luxury yacht owned by a Russian oligarch floating in the waters of the Seychelles. A visitor to the website can view a collection of images conveying the reality of the situation in Ukraine, including flames visible through the window of a damaged building, a convoy of cars turning back in front of a bridge that has been destroyed, and other scenes. ![]()
