Geospatial file formats

Reading files: geopandas.read_file("path/to/file.geojson")

Supported formats:

ESRI Shapefile
- One "file" consists of multiple files! (.shp, .dbf, .shx, .prj, ...)
GeoJSON
GeoPackage (.gpkg)
...

& PostGIS databases!

Writing to geospatial file formats

Writing a GeoDataFrame to a file with the to_file() method:

# Writing a Shapefile file
geodataframe.to_file("mydata.shp", driver='ESRI Shapefile')

# Writing a GeoJSON file
geodataframe.to_file("mydata.geojson", driver='GeoJSON')

# Writing a GeoPackage file
geodataframe.to_file("mydata.gpkg", driver='GPKG')

Let's practice!
