Tencent Map

Introduction

L7 geographical visualization focuses on the visual expression of geographical data. The map layer needs to rely on third-party maps. Third-party maps are created and managed uniformly through Scene. You only need to pass in map configuration items through Scene.

L7 internally resolves the differences between different map basemaps, and at the same time, L7 manages the operation methods of the map in a unified manner.

The Tencent map currently supported by L7 isJavaScript API GL, which is also the officially recommended version of Tencent Maps.
