 So at InterGIS conference, the President GSI at Hexagon, Dr. Jürgen Dold, was talking about mirror-world Germany's digital twin. In this presentation he visualized a future in which a consistent, precise and cost-effective digital twin of Germany will help predict and mitigate disasters, support infrastructure planning and able-sustainable city planning and much more. So cloud-based visualization and collaboration platform could link this digital twin to real-time data and yield further insights through simulations, making such information available to everyone will help governmental and private actors collaborate and make informed decisions. So Hexagon's portfolio offers a range of solutions for creating and leveraging such mirror-worlds. And at Hexagon 2021, Hexagon announced Metro HD city data, which is a new offering of ultra-high-resolution duty and 3D digital-to-twins of major cities. It is an off-the-shelf product through the HXGN content program. And about this, because I'm not the expert about this, I'm going to talk now to Dr. Uwe Bacher from Hexagon Geosystems. Welcome to InterGeoTV. Thanks for inviting me. Yeah, because I got a lot of briefing and I read these words and names and applications, but I mean you're here for explaining to us what it exactly means. So just could you tell us about this content program and why does Hexagon offer high-definition city data as a part of it? Yeah, let's start with the content program. The content program is our data program where we offer country-wide aerial data over the whole U.S., captured every year or every second year. It depends a bit in really high resolution, 15 centimeters usually. And also we do the same for Europe also rapidly. Now we have captured it for huge parts of Europe already second time. The resolution at the moment is 30 centimeters, but we also move into 15 centimeters on a really wide coverage. And this means we offer aerial imagery, but also derived products from this like elevation models or land use data for really large areas in a consistent way that is really useful for analysis. And that's also a bit the basis for, as Jürgen mentioned, the digital twin for whole country. If you have enough information, then you can really manage a country or if a problem or disaster happens, you need this consistent information. Okay, so what exactly does the METRO HD include, METRO HD? Yeah, METRO HD or as we also call it city program. That's a much easier city program. It's much easier, absolutely. That contains, in addition to our wide area coverage, city data. So we really take data or acquire data for certain cities like Munich, New York, Tokyo, what we already did in a really high resolution. At the moment it's 5 centimeters, so you really can see small details on the imagery. But this is really important because cities are growing more and more and there is a huge flow of people moving into the cities. And that also means in the context of climate change and all the things that happened over the last years that the management of a city becomes more and more complex. So there is a huge need for managing cities and to manage something you really need to know what to manage. So you need to have an understanding of the spatial relationship between assets and buildings and roads and so on. And that's to have a smart city, as we call it, if we connect all the data from different sources, we need a kind of digital twin of the city. So really building inside a computer or our network the digital representation of the city, meaning where are the buildings, what are the buildings looking like, how are they connected and we don't stop only with the geodata here. We also include additional data from public sources, from other information sources and then starting with our analysis on this to really offer the decision makers in the end easy to use dashboard that they can just take to make the decision to have all the information that is necessary for them at the right moment in an easy way and just by looking onto a dashboard, usually web-based, to get all this information. This seems so fascinating to me to capture all those data from different sources and then you have one platform and you see everything in different angles. Yes, but also you are focused to the right thing so we have different applications for different use cases and really the right person gets the right view on the data at the right moment. You talked about the different sources and how does Sektagon capture the data? To capture the data we developed a really unique sensor system, it's called the city map, it's a hybrid sensor system consisting of six cameras, two of them pointing directly to the ground, they have cameras in RGB, red, green and blue and also near infrared camera and then in addition to this we have four oblique cameras that are pointing 45 degrees to the front, to the back and to both sides and in addition to this, and that makes it really unique, we have added a LiDAR scanner to it, a first-class LiDAR scanner what is an active system to measure the, let's say the elevations of every single object on the ground and by combining these data sources, these complementary sources or sensors into one platform we are able to capture a really huge variety of different data types and combining them in a way that we use the strengths of both subsystems so to say and to overcome the weaknesses of our system by doing this. That's our main source, so we usually take the sensor, it's quite a huge thing, 80 kilograms installed in a manned aircraft and flying over the cities in a usually patterned up and down the city mapper, okay, okay and what applications is the data typically used for to? Yeah, the applications are very wide so it has everything to do with management of the cities somehow, security infrastructure, but also a lot of going into sustainability of cities because as we have added a LiDAR scanner to it we are able to measure very well vegetation and ground in one so we are able to model for example trees by our AI-based analysis software or tools, we are able to do a land use classification so we know where the surface is sealed or imperious, where water cannot flow away, let's say and also where heat islands might be in the end and then by combining this with tree data we are able to model heating in the city, we are also able to manage fresh air flows or all these things to get really sustainable city in the end and that's, I didn't mention all the products yet, so we have a really wide variety of data that we produce from our hybrid sensor data so starting from image data this site looking gives us information about the facade so we know what buildings are used for what how many stories they have and so by combining all these data sets we are able to have a really I always call it unlimited number of applications, wow that's cool, how can I get access to it? If you're excited we have our sales channels directly inside Hexagon, we work with partners, we work with integrators who use the data and put more value on it somehow and we also have an online platform HXDR where we offer it online so really to stream or to access it via web portal so it's pretty easy just click on our web page or contact us to get more of the data. Super cool that sounds so interesting, thank you for joining us here on InterGio TV Uwe Bacher from Hexagon Geosystems. It was a pleasure being here, thanks a lot for having me here. Thank you.
