  • Google just announced an expansion of the features in Google Maps, that this time get building footprints. The search engine giant has added 25 million new footprints to the app available on both desktop and mobile. You can view detailed structures in major metropolitan regions in USA, like Houston, L.A, Miami and San Francisco. Notice the before (left) and after (right) effect of the update.

    The building footprints go as far as detailing the height and it appears they are algorithmically created by taking aerial imagery and using computer vision techniques to render the shapes. The process enabled Google to get more building footprints than before and create a detailed map, surpassing all of its rivals in the field of commercial mapping. There’s always the community mapping tool Google Map Maker, where you can contribute to confirming the accuracy of the footprints.

    The Map Maker I mentioned allows you to associate a building shape with a business or company and even draw the building footprint, if you want. I expect this to evolve further in the following months, as we approached a detailed Street View level of each corner of those massive skyscrapers and blocks.
