GeoIO.jl uses various backend packages spread across different Julia organizations to load a universal representation of geospatial data as discussed in the book Geospatial Data Science with Julia
The current list of supported formats can be obtained with:
julia> using GeoIO
julia> GeoIO.formats()
┌───────────┬───────────────┬───────────────┐

├───────────┼───────────────┼───────────────┤
│ .geojson │ GeoJSON.jl │ GeoJSON.jl │

Many other formats are being added. If you would like to help, check the list here .
If you are good at reducing pre-compilation time of Julia packages, we highly appreciate your help here .

Added support to load/save all non-parallel VTK formats with ReadVTK.jl and WriteVTK.jl: .vtu, .vtp, .vts, .vtr, .vti
Needs more testing, but the release is out.

GeoJSON files are now loaded with native coordinate reference system (CRS) from CoordRefSystems.jl:

The fix option in GeoIO.load was replaced by repair as explained in the new docstring. The option can be set to false if repairing geometries by default is not desired (e.g., large geotables).
All repairs are now implemented using Repair transforms from Meshes.jl

GeoTIFF files are now loaded with native Julia CRS, assuming a projected coordinate system (e.g., Mercator, UTM, etc.). Geographic coordinates are not supported yet.

All GeoTIFF files are now loaded with native Julia CRS, including those with a geographic coordinate system.
Cross-posting a concrete example:
A few tweaks here and there, and we are now able to visualize moderately large “raster” data stored in GeoTIFF files with any CRS in native Julia.
To illustrate the feature, consider the following example with data from the NaturalEarth project:
using GeoStats
using GeoIO
import GLMakie as Mke
# https://www.naturalearthdata.com/downloads/50m-raster-data/50m-gray-earth
raster = GeoIO.load("GRAY_50M_SR_OB.tif") |> Coerce(Continuous)
# upscale for 3D mesh visualization
coarse = raster |> Upsca…
New option lenunit to specify the unit of coordinates in file formats that don’t include units in their specs (e.g., obj, msh, off, stl)

The option lenunit is now available in all backends.
Predefined columns in specific backends are now lowercase.
Example: COLOR → color, DATA → data
