Description
Target Use Case
Deck.gl has MVTLayer, which allows displaying vector tiles in geographic (latitude and longitude) coordinates. Microscopy and possibly other applications need to be able to display vector tiles in Cartesian coordinates.
Proposal
I have written a an implementation which instantiates TileLayer, which parses tiles using MVTLoader.parse and displays them using GeoJsonLayer. These tiles use Cartesian coordinates to specify polygon vertex positions. I was wondering if it would be useful to have open a PR with this functionality.
I think this could evolve into either:
- A
coordinateSystemproperty onMVTLayer, which can be eithercartesianorgeospatial - A new layer, which can be called
CartesianTileLayer
When researching this topic, I think I saw a post from @cornhundred related to this issue a while ago.

- Comment on the issue to say you are picking it up — it saves two people doing the same work.
- Fork the repository and make your change on a branch.
- Open a pull request that references the issue number.
Research direction
Start by reading the existing MVTLayer and TileLayer entry points, along with MVTLoader.parse and GeoJsonLayer, to understand how geographic vector tiles are currently handled. The issue needs a decided API direction—an MVTLayer coordinateSystem option or a CartesianTileLayer—before implementation can be considered done.
