Load/save geospatial data compatible with the GeoStats.jl framework.
GeoIO.jl uses various backend packages that are spread across different Julia organizations to load and save the universal representation of geospatial data described in the book Geospatial Data Science with Julia.
The load and save functions are self-explanatory:
using GeoIO
table = GeoIO.load("file.shp")
GeoIO.save("file.geojson", table)Additional keyword arguments are forwarded to the backends:
# read `.geojson` geometries with Float64 precision
table = GeoIO.load("file.geojson", numbertype = Float64)
# force writing on existing `.shp` file
GeoIO.save("file.shp", table, force = true)To see the formats supported by GeoIO.jl, use the formats function.
