使用Python 将shapefile导入mongodb

使用Python 将shapefile导入mongodb

随着big data时代的到来，各个行业都在考虑能不能把big data的思路、方法引入进来，GIS行业也不能免俗。

下面就介绍一下如何将shapefile导入mongodb中

1首先安装pyshp 和pymongo 库

2 安装mongodb，并正确运行

3 执行下面的python脚本

import pymongo

from pymongo.connection import Connection

def readSHPPoint(append):

fileP = u'E:\\data\\supermarket_webMercator\\supermarket.shp'

sf = shapefile.Reader(fileP)

shapeRecs = sf.shapeRecords()

mongodb_server='192.168.120.100'

mongodb_port = 27017

mongodb_collection ='supermarket'

mongodb_db = 'gisdb'

connection = Connection(mongodb_server, mongodb_port)

print 'Getting database %s' % mongodb_db

db = connection[mongodb_db]

print 'Getting the collection %s' % mongodb_collection

collection = db[mongodb_collection]

if append == False:

print 'Removing features from the collection...'

collection.remove({})

print 'Starting loading features...'

for shaperec in shapeRecs:

mongofeat = {}

#'{x='',y=''}'

strX = "%.3f" % shaperec.shape.points[0][0]

strY = "%.3f" % shaperec.shape.points[0][1]

mongogeom = '{x="'+strX+'",y="'+strY+'"}'

print mongogeom

mongofeat['geom'] = mongogeom

mongofeat['name'] = shaperec.record[1].decode('GB2312').encode('utf-8')

collection.insert(mongofeat)

#create 2d index

collection.create_index([("geom", pymongo.GEO2D)])

if __name__ == "__main__":

readSHPPoint(False)

目前mongodb只支持点类型的数据，并提供空间索引。

使用mongodb可以很方便的满足高并发的并且简单的需求，例如POI的周边查询API查询
