How often is the US Building Footprints dataset updated?

As the title indicates, I'd like to know if and how often Microsoft plans to update its US Building Footprints dataset: https://www.microsoft.com/en-us/maps/building-footprints

I read on Github that some of the footprints were extracted from 2019-2020 images while others were extract from older images. Do you have any plans to update the dataset based on newer images?

Thanks,

Eric

    Hi Eric,

    The best place to ask this is in the GITHUB for the dataset you are interested in. My fast answer would be not very often as rural buildings don't change much the impact would be more around urban and sub-urban centers. For the US, the only time we can get clean imagery is in summer. That means we don't get that data until fall. Then it takes a great amount of time, space and processing power to convert that imagery into map tiles which then can finally be scanned for new building footprints.

    That being said, we did just that in 2022 https://blogs.bing.com/maps/2022-01/New-and-updated-Building-Footprints so there could be more coming if bing maps does a big enough imagery update to justify it.

    Sincerely,
