Getting Parcels#

First step in building distribution model is to get parcels. You can either bring your own parcels or provide location from where parcels will be downloaded.

There are three helper functions provided in SHIFT that enables users to fetch parcels

  • parcels_from_csv: Fetching parcels from csv. Only requirement for this csv is it needs to have geometry column. Shift uses geopandas to load geometries from this file. Currently we only support Point, Polygon and MultiPolygon shapes.

from shift import parcels_from_csv
points = parcels_from_csv("my_parcel.csv")

  • parcels_from_location: You can also fetch parcels by providing location. You can also provide point or polygon to fetch parcels.

from shift import parcels_from_location
from infrasys.quantites import Distance
points = parcels_from_location("Fort Worth, TX", Distance(400, "m"))

  • parcels_from_geodataframe: Finally, you can also fetch parcels directly from a geodataframe.

Now if you want to visualize these parcels. You can leverage plot manager.

from shift import PlotManager, GeoLocation, add_parcels_to_plot
import osmnx as ox
coordinate_center = GeoLocation(*reversed(ox.geocode("Fort Worth, TX")))
plot_manager = PlotManager(center=coordinate_center)
add_parcels_to_plot(points, plot_manager)
plot_manager.show()
