 Good morning to the community of aerial solutions, it's the third day of the intergeo and I want to present you some thoughts slides about how to create a digital twin. First of all, one short information about the cooperation between DJI and GlobeFlight. GlobeFlight is the general distributor for the DJI Enterprise products in Germany and Austria and we have a very strong cooperation with DJI and work very strong together and very successful and with our more or less 100 resellers in both countries, we make the business of DJI Enterprise products. Okay, that's all for the introduction. Now we have two major tasks and for the surveying society that we have discussed into the UAV section. One is BIM, the Building Information Modelling and how to create the data for the BIM process and one is upcoming and special here in Germany is a question of a digital twin, not for the machine manufacturer, that's a complete other discussion more or less here for the urban space and here the product in the UAV section is upcoming to a very important solution how to create the digital twins and in the discussion here at the interview we discussed already three major points one is the point how is the accuracy and how many how is the requirements of the accuracy for a digital twin, what level of detail what is needed for a digital twin in an urban space and at which intervals have we updated the digital twins is it in the last time when we start the aerial surveying solution we started with five years with six years and actually it's more or less three years and it's increasing for the next year so I expect that we talk about one year update or an update when a building was built and here we have three different possibilities to create the digital twin one is the terrestrial laser scanning and the mobile mapping that creates a very high size of information in a very short time but these both solution is very limited in a high above the ground you know it as a specialist that you can use this to solutions at a height of maybe 20 meters then it's over and what's about all the information in the urban space what is above 20 meters and here the UAV is the best solution to create the data that we need and here the UAVs are a very good solution because it's simple to use large areas can be covered in a very short time the flight times are increasing so you can reach a very large area in a very short time and with new payloads that I will present today to you you have a more detailed information with only one flight and here I will show you two two major projects from our side and the general problem here that are the regulations from the aviation authority that is a little bit bumping here the possibilities of UAV using in Europe today I will show you at first a project with a share camera with an oblique camera that we expect in a very important way for creating a diggleted twin in the urban space the oblique camera has this special thing that they have five camera and you make five images at one point of flying and we tested here in Germany in a mid-sized town in in in Hessen near Kassel it's a community of Biber, Hof Biber and this town needs some more information for urban plannings, for flood protection plannings and for heavy rain simulations they need the digital twin to do this job and we have a special partner there who is creating the digital twin and I want to show you a small flight here we have the area of five square kilometers with more than 40 000 images from this oblique camera and the flight time was one working day that was quite easy and we need a processing time with DJI Terra around about 30 hours and I can show you a little results the first results of this project and I have a laser beam up perfect here you see a very detailed information about the town and you see here the colors are very good and I marked three or four areas that is very special when you use an oblique camera because you can collect more information for a vertical for all vertical walls and you see here a very the laser is not working it's a screen that's normal you see at the rooftops at the corner of the roof it's very clear very precise to collect when we looked at the church you see a lot of details and in the vertical walls of the church and very detailed that's only one one flight at around about 100 meters about above ground yeah okay that's okay the rest of the present I have to try to explain a little bit only with words because the technical failed um we see ah okay it's back but it's not back okay you see it very very detailed that is was with a one lens solution what not not possible okay I try the second solution I want to present to you was um our completely new L2 our new LiDAR from DJI that we released at Tuesday and here I can show you the first results also from a construction site but we have to postpone that please come to our booth at Hall 27 then I can show you the data also in real time and then we can discuss all the things that you want to ask and we see with this simple solutions that we can increase all the questions and we can answer the questions round about how to collect the data from a digital twin okay with with all the presentation I'm a little bit limited so thank you very much for joining for for visiting us and I'm with the first speaker I'm in time I see and I hand over to the next presenters
