Load geospatial tables from known file formats and convert the geometries to Meshes.jl geometries that are compatible with the GeoStats.jl ecosystem.

Geometries are loaded from disk in pure Julia whenever possible using packages such as Shapefile.jl and GeoJSON.jl, or (down)loaded from the internet using the GADM.jl package.


Loading data from disk

The load function loads data from disk:

julia> using GeoTables

julia> table = GeoTables.load("/path/to/file.shp")
4 GeoTable{2,Float64}
    └─ACRES (Float64)
    └─Hectares (Float64)
    └─MACROZONA (String)
    └─PERIMETER (Float64)
    └─area_m2 (Float64)
  domain: 4 GeometrySet{2,Float64}

Loading data from GADM

The gadm function (down)loads data from the GADM project:

julia> t = GeoTables.gadm("BRA", children=true)
27 GeoTable{2,Float64}
    └─CC_1 (String)
    └─ENGTYPE_1 (String)
    └─GID_0 (String)
    └─GID_1 (String)
    └─HASC_1 (String)
    └─NAME_0 (String)
    └─NAME_1 (String)
    └─NL_NAME_1 (String)
    └─TYPE_1 (String)
    └─VARNAME_1 (String)
  domain: 27 GeometrySet{2,Float64}

Performance tips

The result can be easily converted into any other table type to avoid converting the geometries every time the underlying domain is queried.
