"China's first real 3D online digital Earth" is a self-introduction provided by dt.com on its official website. 3D Virtual Earth platform is not a new concept. In recent years, giants such as Google and Microsoft have established virtual earth projects and have extended a variety of location-based hot applications.

The special feature of dt.cn is that it not only provides Earth satellite images, but also allows users to perform virtual tours in city models. The developed 3D engine can render the 3D precision model of the city's massive data volume in real time, even in the normal Web browsing status, it can be very smooth and smooth, without any lag, this is obviously better than Google and other Earth services.

Unfortunately, the city's 3D model data is not rich enough. It only contains 3D models in some hotspot regions in Beijing.

It is particularly worth mentioning that as an open platform, dt.cn also provides API interfaces, and any location-based application can run on its platform.
