深海游弋的鱼 – 默默的点滴

1.安装PostGIS插件

sudo apt-get install PostGIS
sudo apt-get install postgresql-9.3-postgis

1 2	sudo apt-get install PostGIS sudo apt-get install postgresql-9.3-postgis

2.开启PostgreSql对于PostGIS 的支持，在psql 或者 PgAdmin 中执行命令

-- Enable PostGIS (includes raster)
CREATE EXTENSION postgis;
-- Enable Topology
CREATE EXTENSION postgis_topology;
-- fuzzy matching needed for Tiger
CREATE EXTENSION fuzzystrmatch;
-- Enable US Tiger Geocoder
CREATE EXTENSION postgis_tiger_geocoder;

-- Enable PostGIS (includes raster)

CREATE EXTENSION postgis;

-- Enable Topology

CREATE EXTENSION postgis_topology;

-- fuzzy matching needed for Tiger

CREATE EXTENSION fuzzystrmatch;

-- Enable US Tiger Geocoder

CREATE EXTENSION postgis_tiger_geocoder;

3.测试例子

-- Create table with spatial column
CREATE TABLE mytable ( 
  id SERIAL PRIMARY KEY,
  geom GEOMETRY(Point, 26910),
  name VARCHAR(128)
); 

-- Add a spatial index
CREATE INDEX mytable_gix
  ON mytable 
  USING GIST (geom); 

-- Add a point
INSERT INTO mytable (geom) VALUES (
  ST_GeomFromText('POINT(0 0)', 26910)
);

-- Query for nearby points
SELECT id, name
FROM mytable
WHERE ST_DWithin(
  geom, 
  ST_GeomFromText('POINT(0 0)', 26910),
  1000
);

-- Create table with spatial column

CREATE TABLE mytable (

id SERIAL PRIMARY KEY,

geom GEOMETRY(Point, 26910),

name VARCHAR(128)

);

-- Add a spatial index

CREATE INDEX mytable_gix

ON mytable

USING GIST (geom);

-- Add a point

INSERT INTO mytable (geom) VALUES (

ST_GeomFromText('POINT(0 0)', 26910)

);

-- Query for nearby points

SELECT id, name

FROM mytable

WHERE ST_DWithin(

geom,

ST_GeomFromText('POINT(0 0)', 26910),

1000

);
