Fiona: access to simple geospatial feature data
Fiona streams simple feature data to and from GIS formats like GeoPackage and Shapefile. Simple features are record, or row-like, and have a single geometry attribute. Fiona can read and write real-world simple feature data using multi-layered GIS formats, zipped and in-memory virtual file systems, from files on your hard drive or in cloud storage. This project includes Python modules and a command line interface (CLI).
Here’s an example of streaming and filtering features from a zipped dataset on the web and saving them to a new layer in a new Geopackage file.
import fiona with fiona.open( "zip+https://github.com/Toblerity/Fiona/files/11151652/coutwildrnp.zip" ) as src: profile = src.profile profile["driver"] = "GPKG" with fiona.open("example.gpkg", "w", layer="selection", **profile) as dst: dst.writerecords(feat in src.filter(bbox=(-107.0, 37.0, -105.0, 39.0)))
The same result can be achieved on the command line using a combination of fio-cat and fio-load.
fio cat zip+https://github.com/Toblerity/Fiona/files/11151652/coutwildrnp.zip --bbox "-107.0,37.0,-105.0,39.0" \ | fio load -f GPKG --layer selection example.gpkg
