Question

I have a geospatial plot dataframe, and want to plot it.

I am working on a Jupyter notebook running by Databricks.

I downloaded a shapefile (https://data.london.gov.uk/download/statistical-gis-boundary-files-london/9ba8c833-6370-4b11-abdc-314aa020d5e0/statistical-gis-boundaries-london.zip), and manage to subset only a section of London using:

import geopandas as gpd
import descartes
import pandas as pd
import matplotlib.pyplot as plt
fp = '/dbfs/FileStore/tables/LondonShapeFile/OA_2011_London_gen_MHW.shp'
map_df = gpd.read_file(fp, encoding="utf-8")
orp = map_df[map_df['WD11NM_BF']=='Orpington']
print(orp.shape)
orp.plot()

I get:

(50, 18)
Out[95]: <matplotlib.axes._subplots.AxesSubplot at 0x7f064e8df5c0>

I did not get a plot, so tried:

%matplotlib inline

but got:

%matplotlib inline is not supported in Databricks.
You can display matplotlib figures using display(). For an example, see https://docs.databricks.com/user-guide/visualizations/matplotlib-and-ggplot.html

Following the suggested example on https://docs.databricks.com/user-guide/visualizations/matplotlib-and-ggplot.html works,

import numpy as np
df3 = pd.DataFrame(np.random.randn(1000, 2), columns=['B', 'C']).cumsum()
df3['A'] = pd.Series(list(range(len(df3))))
dd=df3.plot(x='A', y='B')
display(dd.figure)

but when I try to implement something similar with the geopandas df, I get multiple errors:

orp.dipslay()

Answer 1

DataBricks不能正常工作，因此我按照以下步骤在笔记本电脑（Windows 10）上运行它并可以正常工作。

Windows 10 installation of geopandas
1) I go this website to download the following installation files (.whl):
    https://www.lfd.uci.edu/~gohlke/pythonlibs/
        1.1) Shapely
        1.2) GDAL and
        1.3) Fiona
2) Go to the download file and run in anaconda prompt
     pip install < *.whl>  for Shapely, GDAL and Fiona

Answer 2

此解决方案最终奏效了

fp = '/dbfs/FileStore/tables/LondonShapeFile/OA_2011_London_gen_MHW.shp'
map_df = gpd.read_file(fp, encoding="utf-8")
print(map_df.shape)
ldn = map_df.plot()
display(ldn.figure)

jupyter notebook does not show geospatial plot when running in databricks
