Question

我使用pysal / cenpy提取了地理信息，但是对象通过调用质心返回了错误

import cenpy as cen
import pysal as ps
import geopandas as gpd 

dataset = 'ACSSF5Y2015'
con = cen.base.Connection(dataset)

con.set_mapservice('tigerWMS_ACS2017') 
geotmp = con.mapservice.query(layer=84, where='STATE=' + str(1))
type(geotmp)
#pandas.core.frame.DataFrame
type(geotmp.geometry[0])
#pysal.cg.shapes.Polygon

geotmp.geometry.centroid
AttributeError: 'Series' object has no attribute 'centroid'

在gds-scipy16

的内置数据集中进行了检查

type(data_table)
#pandas.core.frame.DataFrame
type(data_table.geometry[0])
#pysal.cg.shapes.Polygon

data_table.geometry[0].centroid
#(-94.90336786329912, 48.771730563701574)

如何更正错误？

尽管这不能直接回答您的问题，但有一个ffmpeg -i input.mp4 -vf "drawtext=enable='between(t,0,5)':fontfile=font.ttf:text='Some caption':x=60:y=640:fontsize=40:fontcolor=#f0f0f0@0.9" -vcodec libx264 -crf 27 -preset ultrafast -strict -2 -acodec copy output.mp4的较新的预发行版本，它更加简化，可以避免您上面描述的问题（请参见下面的示例）。 Instructions for installing the pre-release can be found here和a gist demonstrating functionality here。

cenpy

import cenpy
cenpy.__version__

>>> '1.0.0dev'

florida = cenpy.products.Decennial2010().from_state('Florida')

>>> Matched: Florida to Florida, FL within layer States

type(florida)

>>> geopandas.geodataframe.GeoDataFrame

type(florida.geometry[0])

>>> shapely.geometry.polygon.Polygon

print(florida.geometry[0].centroid)

pysal多边形对象不返回质心
