Introduction Julia is a high-level, high-performance programming language that is becoming increasingly popular for geospatial data science. There are a number of great geospatial packages available for Julia, each with its own strengths and weaknesses. In this article, we will discuss the 5 best geospatial packages to use in Julia, and how to best use each of them.
What it does: GDAL.jl is a thin Julia wrapper for the GDAL library, which is a powerful open-source library for reading, writing, and manipulating geospatial data. GDAL.jl allows you to read and write a wide variety of geospatial data formats, including Shapefiles, GeoTIFFs, and KML files.
How to use it: GDAL.jl is easy to use. To read a Shapefile, for example, you would use the following code:
shp = GDAL.open("my_shapefile.shp")
Once you have opened a geospatial dataset, you can use GDAL.jl to access its features, attributes, and metadata.
What it does: GeoDataFrames.jl is a Julia package that provides a geospatial extension to the popular DataFrames.jl package. GeoDataFrames.jl allows you to store geospatial data in a DataFrame, which makes it easy to manipulate and analyze this data.
How to use it: GeoDataFrames.jl is easy to use. To create a GeoDataFrame from a Shapefile, for example, you would use the following code:
shp = read_shapefile("my_shapefile.shp")
df = GeoDataFrame(shp)
Once you have created a GeoDataFrame, you can use it like any other DataFrame. You can access its features, attributes, and metadata, and you can use it to perform a variety of geospatial analysis tasks.
What it does: GeoJSON.jl is a Julia package that provides a parser and serializer…
