Agigapixel image is a digital image bitmap composed of one billion (109) pixels (picture elements), 1000 times the information captured by a 1 megapixel digital camera. A square image of 31,623 pixels in width and height is one gigapixel. Current technology for creating such very high-resolution images usually involves either making digital image mosaics of many high-resolution digital photographs or using a film negative as large as 12" 9" (30 cm 23 cm) up to 18" 9" (46 cm 23 cm), which is then scanned with a high-end large-format film scanner with at least 3000 dpi resolution. Only a few cameras are capable of creating a gigapixel image in a single sweep of a scene, such as the Pan-STARRS PS1 and the Gigapxl Camera.[1][2]

A terapixel image is an image composed of one trillion (1012) pixels. Though currently rare, there have been a few instances such as the Microsoft Research Terapixel project for use on the Fulldome projection system,[3] a composite of medical images by Aperio,[4][5] and Google Earth's Landsat images viewable as a time-lapse are collectively considered over one terapixel.[6]


To preface the instructions, the gigapixel feature of StoryMap is not as easy to use as most of our other tools because it requires hosting a folder of image tiles on a web server. If you are unable to serve your images and make them accessible through the web, you won't be able to use the gigapixel feature of StoryMap. Also, since we created the tool, some of the options for creating the image tiles no longer work. However, we still see new Gigapixel storymaps published, so be assured that it's possible.


You'll start with a large image for your gigapixel project. It doesn't actually need to be a gigapixel image, but images you take with your phone won't be big enough to be interesting. You need to know the image width and height in pixels as part of starting a gigapixel StoryMap.


Once you have a large image, export it as tiles. Windows can use the Zoomify Free app. A Mac download is provided, but it does not work on modern MacOS. Photoshop no longer offers a Zoomify export, unfortunately.


More technically-minded users can use command-line tools such as VIPS. For Mac users, VIPS can be installed using homebrew. It takes quite a while, but works well once it is installed. The Windows version is already compiled, so is more easily downloaded, but also, there's no reason we know that Windows users shouldn't just use Zoomify Free, mentioned above.


After you have your image tiles up on a server, go to make a new StoryMap, the same as you would for a conventional storymap. When you get to the main StoryMap editor screen, click on the "options" button near the top left. Set the "map type" to "Gigapixel" and enter the base URL for your image tiles, and the width and height of the original image.


Previously, Gigapixel tiles were able to be hosted on Google Drive and Dropbox. Both platforms have since changed their rules, and now no longer suporting hosting tiles. Outside of hosting your tiles yourself, we have found two alternatives:


The picture was made with the 50-megapixel Canon 5DSR and a 100-400mm lens. It consists of 912 photos with each one having a .RAW file size of over 60MB. To create the image a robotic camera mount was used to capture over 900 images with a Canon 5DSR and 400mm lens. Digital stitching software was then used to combine them into a uniform high-resolution picture.


With a resolution of 300,00055,313 pixels, the picture is the highest resolution photo of Quito ever taken. This allows you instantly view and explore high-resolution images that are over several gigabytes in size.


I finally settled on taking the image from near the top of the Pichincha Volcano. Pichincha is classified as a stratovolcano and its peak is over 15,000ft high. I was to access the spot via a cable car and it gave a huge panoramic vista of the entire city as well as all the volcanoes that surround Quito.


Visibility: The second factor that goes into atmospheric conditions is visibility, also called visible range is a measure of the distance at which an object or light can be clearly discerned. Mist, fog, haze, smoke, dust and even volcanic ash can all effect visibility.


Camera: I decided to use a 50 megapixel Canon 5DS R. The 5DS R is an amazing camera that is designed without a low-pass filter which enables it to get amazing pixel-level detail and image sharpness.


Lens: A Canon 100-400mm f/5.6 II lens was used to capture the image. Several factors went into the decision to use this lens such as size, wight and focal length. The 100-400mm was small and light and would allow the robotic pano head to function with no problems. It also has a good focal length of 400mm with would allow for some nice detail to be captured.


Pano Head: I used a GigaPan Epic Pro for the image capture. The GigaPan is an amazing piece of equipment which automates the image capture process. The GigaPan equipment is based on the same technology employed by the Mars Rovers, Spirit, and Opportunity, and is actually a spin-off of a research collaboration between a team of researchers at NASA and Carnegie Mellon University.


To use a GigaPan you first need to set it up for the focal length of the lens that you are using. You then tell it where the upper-left-hand corner of the image is located and where the bottom-right-hand corner of the image is. It then divides the image into a series of frames and automatically begins scanning across the scene triggering the camera at regular intervals until the scene is completely captured.


Aperture: I set the aperture to f/8. This was done for a couple of reasons. The first was to increase the resolution of the image. Although the Canon 100-400mm f/5.6 II is a very sharp lens shooting wide open, stopping down the lens a little bit increases its sharpness. Stopping down the lens also reduces vignetting, which is a darkening of the edges and corners of the image.


ISO: I shot at an ISO of 640 due to all the wind at the site. I knew that using a high ISO would increase my shutter speed and reduce the chance of vibrations from the wind blurring the photo.


Live View: I used the cameras live view function via Canons EOS Utility to raise and lock the mirror during the capture sequence. This reduced the chance of mirror slap vibrating the camera.


The GigaPan has a lot of different settings for the capture sequence of the images. One can shoot in columns from left to right or in rows from the top down and left to right or any combination thereof. I choose to shoot the image going across in rows from top down going from left to right. Even though the image capture sequence would only take an hour or so I have found that shooting in this sequence makes for a more natural looking image in case of any change in lighting conditions. I also included a 1-second pause between the GigaPan head moving and the trigger of the camera to reduce any shake that may have been present from the pano head moving.


Two Image Sets: Each day of the shoot presented itself with different problems. One day the city was clear but the horizon and volcanoes were obscured with clouds. On another day the horizon was totally clear. I decided to create two different image sets and combine them together to make the final image. One large image set was used for the clear sky and volcanoes another image set was used for the city.


For the image set of the city found an exposure of the city and color corrected and sharpened it to the way I wanted it before bringing the images into the stitching software. I recorded the image adjustments that I made and made a photoshop droplet with them. I then dragged and dropped all the files onto the droplet and let it run, automatically correcting each image of the photo sequences. It took a long time but it worked.


Autopano Giga: After the images were captured I put all of them into Autopano Giga. Autopano is a program that uses something called a scale-invariant feature transform (SIFT) algorithm to detect and describe local features in images. These features are then matched with features in other frames and the images are combined or stitched together. The software is pretty straightforward but I did a few things to make the final image.


Photoshop: I had to stitch one image for the horizon and another image for the background. Once these were done I opened them up in photoshop and used the eraser tool set to a large diameter to manually tool to manually blend them together. I then flattened the image and saved it as a .PSB file.


Image Tiling: I used a program called KRPano to make a tile of the images. If I uploaded the resulting .PSB file to the internet it would take forever for it to load up so people could see it. KRPano divides up the image into layers of small tiles. Each image you see is made up of a low-resolution tile. As you zoom into the image different small image tiles are quickly loaded and displayed with allows people to quickly view and explore the image without having to load the entire image. About 174,470 tiles were created for this image.


Once all the image tiles were created I compressed them into a .zip file. I felt that it would be easier to upload one large file instead of over 174,000 separate small files. The image upload went fine and I manually unzipped the image inside of the Hostgator server using FileZilla. It is good to check with the hosting company to make sure that they allow files to be unzipped inside their servers.


I hope that this little guide proves helpful for all of you. Gigapixel technology is really interesting and fun to try out. I have done quite a few gigapixel images but am by no means an expert and am always interested in learning more.
