小编给大家分享一下mongodb导入shapefile数据的方法,希望大家阅读完这篇文章后大所收获,下面让我们一起去探讨方法吧!

两种解决方案:

一、将整个shapefile转为GeoJSON然后直接导入mongoDB数据库中

首先,将shapefile数据转为WGS84地理坐标,然后使用GDAL的命令行工具ogr2ogr进行格式的转换,转换命令如下:

ogr2ogr-fgeoJSONcontinents.jsoncontinents.shp

删除生成JSON文件的前两行{ "type": "FeatureCollection",和最后一行}。

最后,使用mongodb的mongoimport工具进行导入:

mongoimport--dbworld--collectioncontinents<continents.json

这样子整个shapefile文件在mongodb中是以一个document存在的。

二、更加细粒度的存储方法是将shapefile中的每个feature取出来转为GeoJSON存入mongodb

具体实现代码入下(Java版本):

packagecn.tzy.mongodb;importjava.io.File;importjava.io.IOException;importjava.io.StringWriter;importorg.bson.Document;importorg.geotools.data.FileDataStore;importorg.geotools.data.FileDataStoreFinder;importorg.geotools.data.simple.SimpleFeatureIterator;importorg.geotools.data.simple.SimpleFeatureSource;importorg.geotools.geojson.feature.FeatureJSON;importorg.opengis.feature.simple.SimpleFeature;importcom.mongodb.MongoClient;importcom.mongodb.client.MongoCollection;importcom.mongodb.client.MongoDatabase;publicclassMongoEx{publicstaticvoidmain(String[]args)throwsIOException{finalStringIP_ADDRESS="127.0.0.1";finalStringDB_NAME="SpatialFeatures";finalStringCOLLECTION_NAME="continents";finalStringSHAPE_FILE="/home/theone/Data/World/continent.shp";MongoClientclient=newMongoClient(IP_ADDRESS,27017);MongoDatabasedb=client.getDatabase(DB_NAME);db.createCollection(COLLECTION_NAME);MongoCollection<Document>coll=db.getCollection(COLLECTION_NAME);FileshapeFile=newFile(SHAPE_FILE);FileDataStorestore=FileDataStoreFinder.getDataStore(shapeFile);SimpleFeatureSourcesfSource=store.getFeatureSource();SimpleFeatureIteratorsfIter=sfSource.getFeatures().features();//依次取出每一个Feature转为GeoJSON格式,然后插入到collection中while(sfIter.hasNext()){SimpleFeaturefeature=(SimpleFeature)sfIter.next();FeatureJSONfjson=newFeatureJSON();StringWriterwriter=newStringWriter();fjson.writeFeature(feature,writer);Stringsjson=writer.toString();Documentdoc=Document.parse(sjson);coll.insertOne(doc);}client.close();}}
