1.安装postgreSQL及PostGIS

brew install postgre

brew install postgis

echo “” >> ~.bash_profile
echo “export PGDATA=${PGDATA}” >>.bash_profile
source ~/.bash_profile

sed -i ‘s/#logging_collector = off/logging_collector = on/‘ ${PGDATA}/postgresql.conf

2.初始化数据库实例gis

pg_ctl init gis
psql gis -c “CREATE DATABASE gis;”

3.在数据库实例gis中注册PostGIS扩展件

Enable PostGIS (includes raster)

psql gis -c “CREATE EXTENSION postgis;””

Enable Topology

psql gis -c “CREATE EXTENSION postgis_topology;”

Enable PostGIS Advanced 3D and other geoprocessing algorithms sfcgal not available with all distributions

psql gis -c “CREATE EXTENSION postgis_sfcgal;”

fuzzy matching needed for Tiger

psql gis -c “CREATE EXTENSION fuzzystrmatch;“

rule based standardizer

psql gis -c “CREATE EXTENSION address_standardizer;”

example rule data set

psql gis -c “CREATE EXTENSION address_standardizer_data_us;“

Enable US Tiger Geocoder

psql gis -c “CREATE EXTENSION postgis_tiger_geocoder;”

4.从OpenStreetMap网站下载特定城市(比如”BEIJING”)”OSM PBF”格式样例数据集，保存为beijing.osm.pbf。

5.安装“导入osm数据至postgreSQL数据库”的工具osm2pgsql

brew install osm2pgsql

6.将“OSM PBF”导入数据库实例gis。

osm2pgsql -c -d gis beijing.osm.pbf
