[GeoIO.jl](https://github.com/JuliaEarth/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_](https://juliaearth.github.io/geospatial-data-science-with-julia).

The current list of supported formats can be obtained with:

```julia
julia> using GeoIO

julia> GeoIO.formats()
┌───────────┬───────────────┬───────────────┐
│ extension │ load │ save │
├───────────┼───────────────┼───────────────┤
│ .geojson │ GeoJSON.jl │ GeoJSON.jl │

└───────────┴───────────────┴───────────────┘

```

Many other formats are being added. If you would like to help, check the list [here](https://github.com/JuliaEarth/GeoIO.jl/issues/20).

If you are good at reducing pre-compilation time of Julia packages, we highly appreciate your help [here](https://github.com/JuliaEarth/GeoIO.jl/issues/23).

</div>

# GeoIO.jl v1.16

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

> 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…

# GeoIO.jl v1.18

The option `lenunit` is now available in all backends.

### Breaking

Predefined columns in specific backends are now lowercase.

Example: COLOR → color, DATA → data

## GeoIO.jl v1.22

The project reached a very important milestone:

 ![Screenshot_20260313_092612](https://global.discourse-cdn.com/julialang/original/3X/4/4/4463cd531402ba48b5e5d16f7daa2d30b0cef4fd.png)

We no longer depend on external libraries, and this solves a series of issues as reported in [Native support for GeoPackage file format · Issue #167 · JuliaEarth/GeoIO.jl · GitHub](https://github.com/JuliaEarth/GeoIO.jl/issues/167)
