Python Geopy到shapefile

尝试使用geopy返回的纬度和经度创建形状文件。如果我给它一组数字（44.977753，-93.2650108），shapefile creator零件行可以工作，但它不能处理返回的数据lat_long。我的想法是它需要一个“，”但是我不知道

from geopy.geocoders import GoogleV3
import csv
import ogr, os
def geopy(): 

    loc = raw_input("What location? ")
    geolocator =  GoogleV3()
    location = geolocator.geocode(loc, exactly_one=True) 
    if location != None:
        Address = location.address
        lat_long = location.latitude, location.longitude
        latitude = str(location.latitude)
        longitude = str(location.longitude)  
        print Address, latitude, longitude
        print""


    else:
        print "There is no geographic information to return for the word in input. \n"    

# Input data
    pointCoord = lat_long
    fieldName = 'test'
    fieldType = ogr.OFTString
    fieldValue = 'test'
    outSHPfn = "output file"
# create the spatial reference, WGS84
    srs = osr.SpatialReference()
    srs.ImportFromEPSG(4326)

# Create the output shapefile
    shpDriver = ogr.GetDriverByName("ESRI Shapefile")
    if os.path.exists(outSHPfn):
        shpDriver.DeleteDataSource(outSHPfn)
    outDataSource = shpDriver.CreateDataSource(outSHPfn)
    outLayer = outDataSource.CreateLayer(outSHPfn, srs, geom_type = ogr.wkbPoint )

#create point geometry
    point = ogr.Geometry(ogr.wkbPoint)
    point.AddPoint(pointCoord[0],pointCoord[1])

# create a field
    idField = ogr.FieldDefn(fieldName, fieldType)
    outLayer.CreateField(idField)

# Create the feature and set values
    featureDefn = outLayer.GetLayerDefn()
    outFeature = ogr.Feature(featureDefn)
    outFeature.SetGeometry(point)
    outFeature.SetField(fieldName, fieldValue)
    outLayer.CreateFeature(outFeature)    

geopy()

需要添加一个循环以将纬度和经度放入列表中。这段代码将创建您指定的任何位置的点形状文件
