I'm a big supporter of open mapping data and initiatives. I hope companies continue to contribute to the datasets, vs keeping higher quality data within silos.
I registered the domain thislocation.com a while back. Through some other work I'm doing, I'm hoping to release a platform and datasets that allow you to build/upload/download arbitrary metadata schemas that you can attach to a location (coordinate/POI etc).
The data will be freely available to other platforms, OSM compatible as much as possible. The goal is to pull up a location and there could be hundreds of interactive datasets about it specifically or nearby. Anything from a live audio recording of a space, to drone footage, lidar/radar captures.
The project started when capturing lidar & precision gps data recently, and not having an easy, agnostic platform to just upload and allow it to work easily. The goal is to understand common data patterns so the App will just consume where it can, or allow extension via custom schemas where needed. Everything now seems to be poorly design UI's, corporate desktop software, or if it is a modern online platform, it's too specific to a particular vertical.
I don't really feel like the layers/photos etc experience of google earth are really the best way to explore mapping data, as well as displaying thousands of markers. We are trying for different approaches based on the types of media.
A user can keep their data private, or share it publicly but it will be just like opening Google maps online, typing in an address etc, then toggling datasets in a modern, beautiful way that just works. hiding the map when needed, activating different pages when more appropriate. Everything defined in JSON Schema etc, no new standards or KML/XML, maybe compatible exports if needed.
Apologies for the long pitch, just wanted to share about this side project, and love for open mapping data.
