"RoverMap" is Jonas' PhD thesis project. It aims to develop a map framework that displays pure geographic vector data. To maintain a single, cross-platform codebase with native performance, the renderer is implemented in Rust. Multiple backends (Vulkan, Metal, WebGPU) and bindings (C, Kotlin, Swift, .NET) are available resp. in progress. In the talk, Jonas will focus on Rust development for mobile platforms, highlight the architecture of the Kotlin bindings in particular, and present a short map rendering demo on Android devices. Lorenzo might add some notes on a real-world project (an app to rent cargo bikes) that utilizes RoverMap.
