Spatial coordinate support in more adapters

## Feature Request

Let's add support for spatial coordinates in more adapters.

## Description

Which adapters make sense? And which formats already have support for something similar?

Start by surveying the existing adapters and formats that support spatial-coordinate-like data. The issue names no files, tests, or entry points, so first identify the relevant adapter implementations and document which additional adapters should support spatial coordinates and how completion will be verified.
