Tencent Map Industry Version WeMap Upgrade

​On November 10, 2020, WeMap, the industrial version of Tencent's map, was officially released at Tencent's Beijing headquarters. Since its release one year ago, based on real-time perception, comprehensive characterization, precise decision-making, and intelligent services as the core, it has provided a perceptible, computable, and applicable digital map base for the industrial Internet. The Tencent Map Industry Edition has won more than 100 project cooperations in six major industries including smart city, transportation, cultural tourism, and emergency, as well as more than 30 ecological partners.

In August 2021, the Ministry of Natural Resources issued the "Realistic 3D China Construction Technology Outline (2021 Edition)", which proposed a six-point transformation in 3D—from abstraction to reality, from static to dynamic, from human understanding to human-machine compatibility, and from plane To three-dimensional, from sub-scale by element to sub-accuracy by entity, from the surface of the land to the whole space. At the same time, it can be seen from the development of digital twins in multiple industries and the industrial application of CIM that three-dimensionalization has become the general trend.

In this process, the transformation of the map from 2D to 3D also brought new difficulties: poor effect, high cost, slow update, and difficult development. How to solve these problems is a common challenge for the industry.

1. WeMap has been upgraded

Based on the challenges faced by the industry, at the 2021 Tencent Digital Ecology Conference held on November 4, Cao Dongqing, senior director of Tencent's location services, officially announced that WeMap and Unreal have reached a cooperation, with the help of Tencent's advantages in game technology, a new upgrade to WeMap! Cao Dongqing said: "The upgraded WeMap will help industrial customers achieve map visualization capabilities with high fidelity, low cost, fast update, and easy development."

2. Game-level high-fidelity rendering

2.1 High-realistic rendering of cities/buildings

Relying on the accumulation of Tencent's leading game technology, through a rich material library, the beautification of buildings, roads, green spaces, water systems and other elements is formed to achieve highly realistic urban rendering effects.

Two, high simulation environment rendering

Using the game rendering engine's super ability to restore the environment, lighting, shadows, etc., present the city's real day and night, lighting, and weather changes.

3. From the world to the park, breaking through the scene restrictions

Relying on Tencent's own map data system, WeMap generates a three-dimensional model covering all elements from the macro to the micro, realizing the integrated presentation of the digital earth.

4. Automatically generate 3D cities

WeMap automatically generates 3D models based on SD and high-precision map data, reducing the cost of 3D construction of the city. Relying on the live data capabilities of Tencent Maps, the 3D data update cycle is greatly shortened.

Five, UE and Web dual engine open, unified API call

Based on the UE engine, WeMap provides a flexible API to facilitate developers to independently construct 3D application scenarios. At the same time, WeMap also provides a lightweight web-based engine, with a unified B/S architecture for API opening. Developers can take advantage of different rendering engines through a consistent API method, reduce access thresholds, and achieve different effects Seamless switching.

WeMap greatly improves the rendering effect through the game-level engine, and uses Internet map data to automatically build a 3D city model, which greatly reduces production costs and shortens the implementation cycle, and can achieve weekly updates of 3D data.

In addition to the new upgrade of WeMap, Cao Dongqing also announced the official launch of WeMap's official website at the meeting. He expressed the hope that with the launch of WeMap's official website, more industry partners can learn about WeMap and build a new infrastructure for co-creation, co-construction and sharing together!
