What is Aerial Bold?
Aerial Bold is the first map and typeface of the earth. The project is literally about "reading" the earth for letterforms, or alphabet shapes, "written" into the topology of buildings, roads, rivers, trees, and lakes. To do this, we will traverse the entire planet's worth of satellite imagery and develop the tools and methods necessary to map these features hiding in plain sight.
The entire letterform database will be made available as a “usable” dataset for any of your art/design/science/textual projects and selected letterforms will be made into a truetype/opentype font format that can be imported to your favorite word processor.
Only with your support can we turn topography into typography and bring Aerial Bold to you!
Contrary to popular belief, much of the world has not been mapped. While satellites orbit around the earth taking thousands of images each day, we have limited idea about what unique features actually live on those photographs.
Aerial Bold is as much about developing new methods of mapping features on the earth’s surface, as it is about generating the first map and typeface of the planet. It is our intention to offer non-domain experts (e.g. artists, designers, citizen scientists, etc.) a set of tools to source their own datasets and inspire people from all backgrounds to explore geographic data. The importance in kickstarting Aerial Bold is to showcase the creative and technical process of “making your own data”.
As a two-man army, we will be experimenting with “new” ways to train image processing algorithms to find geometric patterns and use these scalable methods to find the shapes of the alphabet over the entire earth.
On a small scale, such as in a community or small city, image processing tasks don’t pose a big challenge, however on a large scale (e.g. the entire earth, or the entire US), the computational requirements can be paralyzing. This is why we’re asking for your help.
With your support we will be able to purchase dedicated computing/server space to run our satellite image based alphabet searching algorithm. The funding support will help keep the typeface, the maps, and the alphabet metadata (e.g. geo-coordinates, address, etc) alive in cyberspace for people to download, use, view, and explore.

How does this all work?
The processing pipeline graphic shows our planned method for deriving the letterforms.The checked, green circles indicate the tasks that we have already completed and/or prototyped and the unchecked, yellow circles indicate the tasks that rely on your funding support for processing power.
The process we are developing is almost completely automated, with more manual steps required for quality checks and input training data. We've mapped out our methodology, we're working on up-scaling and training the algorithms which is no small task.
Example Images of Processing Pipeline
This is a sample of an aerial image that shows some buildings in the shape of the alphabet letter "A".
The image below shows the results of the "image segmentation" process. Image segmentation simplifies an image such that it is easier to differentiate between features. With a segmented image, its becomes more simple for the computer to recognize text.
The image below shows the buildings (in red) and natural land category (in green) vectors from openstreetmap. The alphabet letter "A" shapes can be seen clearly demarcated.
The image below shows the vector data overlaying the aerial image. This combined dataset will help us to find Aerial Bold on the earth's landscape!

Risks and challenges
This is an ambitious project that will require experimentation and a large amount of data wrangling. While we are dedicated to deriving earth’s letterforms by developing the best possible methods using computer vision, there will most certainly be some cases in which more manual labor will be employed. This will be especially true for regions of the world where imagery and data are of lower resolution and less available and when validating each letterform (e.g. is what the computer thinks is an alphabet shape indeed an alphabet shape?).
Through brute-force approach (manually finding letters), we’ve already compiled a complete alphabet dataset, and in many cases have found multiples of each letter. We know there are more out there and we want you to have access to all of them.
Deriving data from satellite imagery is and can be a tricky thing from a legal point of view. All of the companies that provide aerial imagery online (e.g. Google, etc) have specific terms and conditions, which almost always forbid any data mining of the imagery. For some aerial imagery providers, however, there are provisions that allow you to derive data from their imagery (e.g. if the data is contributed to OSM, openstreetmap.org).
These are indeed important considerations, but we’re optimistic and have already planned out ways forward. First, we approach one of the aerial imagery providers and they simply allow us to use the data for this project (we’ll keep you updated!). If we have no luck in accessing pre-made global imagery tileset, no problem! We can start with the parts of the world where imagery is available at high resolutions under public domain (e.g. in the United States) and continue from there. Regardless of the imagery source, we will combine the imagery data with OSM data which includes quite a comprehensive global database of vector buildings, roads, trees, lakes, rivers, etc. Together, these will serve as the basis of our alphabet shapes.
None of these approaches are mutually exclusive.
We are confident that we can bring Aerial Bold to you!Learn about accountability on Kickstarter
