根据研究的城市地理范围确定
bounds=[左下经度,左下纬度,右上经度,右上纬度]
如果你有研究区域的shp或geojson文件,也可以用下面代码直接计算
#读取研究范围
area = gpd.read_file('Data/研究区域.shp')
#获取研究区域的bounds
bounds = area.unary_union.bounds
你好,我想跟进一下这个问题,如果bounds设置为在南半球的话,比如bounds = [153.0084,-27.4875,153.0516, -27.5219] ,使用 tbd.plot_map( ) 会报错:ValueError: Width and height must be >= 0

bounds = [153.0084,-27.4875,153.0516, -27.5219] 应改为[153.0084, -27.5219,153.0516,-27.4875]
import transbigdata as tbd
import matplotlib.pyplot as plt
# bounds = [lon1,lat1,lon2,lat2],其中lon1<lon2,lat1<lat2
bounds = [153.0084, -27.5219,153.0516,-27.4875]
tbd.plot_map(plt,bounds)
plt.show()
谢谢!
请问,对于一个数据,bounds 值如何选取
