An extension to the DataFrames.jl library for handling geospatial data. This Package aims to provide a geopandas equivalent for Julia.
This package is at an early development stage. GeoVector.jl provides a minimal type(GeoVector) that can be used to handle series of AbstractGeometries. GeoDataFrame is a DataFrame containing at least on GeoVector and currently provides plotting based on an other column(numeric). The underliying framework is LibGEOS.jl.
GeoDataFrame (partialy) implements the AbstractDataFrame interface (GeoDataFrame <: AbstractDataFrame). Currently there is only plotting based on numerical columns and w/o a legend.
germany_covid = GeoJSON.read(read("./corona_germany.geojson"))
gdf = GeoDataFrame(germany_covid)
plot(gdf, column=:cases_per_100k, colors=cgrad(:thermal, rev=true))
GeoVector implements the AbstractArray interface (GeoVector <: AbstractVector).
Currently there is only the default constructor:
GeoVector(Vector{AbstractGeometry}, Bool)The following methods are implemented and work like their geopandas equivalent.
