Tomnod: Using Machine Learning & Crowd Sourcing To Build Object Aware Maps Of The World

Earth observation startups like Skybox imaging, Planet Labs, Urthecast among others, have already energized the satellite imagery industry in general and have raised expectations for next generation applications using all this data. The entire earth is being photographed every day and all this “big data” is going to help create the next-gen search engine, where a farmer can simply Google to find out the yield of crops in his/her farmland, the real estate industry can monitor new constructions and so on. There are several steps in creating such an application, the first step being object aware maps of the world.

Machine Learning & Crowd Sourcing

Given all this data, manual methods to identify and demarcate features of interest is going to be very time-consuming and frankly, out-dated. That’s where AI algorithms and crowd sourcing methods come in. While machine learning algorithms can be very effective in distinguishing between different types of objects it encounters in a satellite imagery, one needs to train it with multiple examples of these objects, in order to improve its performance.

It’s like a typical image processing exercise at the university, where one had to select the training pixels in order to be able to help the system demarcate those objects for us e.g. sand, grasslands, built-up area, etc. The more number of pixels one used to train these classes, the better the classification accuracy and a better looking confusion matrix. While it might be a easy task to select training pixels (samples) if we only had one image to classify or even a few, the problem becomes more time-consuming when you have several thousand images to classify. 

It’s the exact same problem the scientists at DigitalGlobe were facing when they wanted to create object aware maps of the world using satellite data that they collect every day. That’s where the crowd sourcing platform from DigitalGlobe, Tomnod comes to the picture.

Tomnod is a team of volunteers (like you!) who work together to identify important objects and interesting places in satellite images. Use Tomnod to explore the Earth, solve real-world problems, and view amazing images of our changing planet. With the help of millions of volunteer contributions, we fulfill our purpose of seeing a better world – Tomnod.com

Tomnod has already helped DigitalGlobe, collect close to 200,000 training examples for more than 20 object classes! Wow, who knew the crowd sourcing community was this active! Interested in being part of the volunteers, here’s the link to this project – Tomnod.

As we move forward, machine learning and AI methods are going to play an important role in the Geospatial indutry,  it’s going to be interesting to see how the Tomnod project helps DigitalGlobe create the next-gen “Google Search Engine” for satellite imagery!

Mapiful: Map Posters were never this #Geoawesome!

MapifulWho doesn’t love awesome maps!? Everyone does (or so I would like to believe 🙂 ),  Needless to say, maps are one of our favorite addictions at Geoawesomeness, be it satellite imagery in the form of carpetsdesigner wear with OSM data, 3D printed Google maps, or the latest one – awesome map posters from OSM data!

Mapiful: Map Posters that are truly geoawesome

Mapiful is a startup based out of Gothenburg, Sweden that helps us print awesome minimalist B&W map posters using OpenStreetMap data.  All you need to do, is to enter the location, adjust the map to get exactly the area you want on the poster and wait for the poster to arrive! 😉

Getting your map poster was never this easy and more importantly, Mapiful posters look really beautiful. the trademark Scandinavian design sense is there for everyone to see.

Did you ever wish for a printed map poster of your hometown or a place where you fell in love? Well, if that place isn’t Paris, London or New York chances are you’ve ended up empty handed. That’s about to change. The world is at your fingertips with Mapiful

The map posters are printed on 200 g/m2 matte paper and comes in two standard sizes – Nordic (50*70 cm) or American (18 * 24 inches). The interface is super easy to use.
