Using Docker Container Postgres
- Create local to save postgres data
docker volume create pg_data
- Create instance posgres with postgis extension
docker run --name=trajectory-data-postgis -d -e POSTGRES_USER=postgres -e POSTGRES_PASS=postgres -e POSTGRES_DBNAME=trajectory-data -e ALLOW_IP_RANGE=0.0.0.0/0 -p 5432:5432 -v pg_data:/var/lib/postgresql --restart=always kartoza/postgis:9.6-2.4
Extra Queries
Create table
- Create table to save output
CREATE TABLE matched_points (
id serial primary key,
natural_id integer,
datetime timestamp,
longitude double precision,
latitude double precision,
edge_id bigint,
offset double precision,
geometry point
);- Create table with content
CREATE TABLE dataset (
id serial primary key,
natural_id integer,
datetime timestamp,
longitude double precision,
latitude double precision
);Aditional columns
- Add column for geometry
ALTER TABLE dataset ADD COLUMN geom GEOMETRY;- Add aditional column for serial id in dataset
ALTER TABLE dataset ADD COLUMN ID SERIAL PRIMARY KEY;Aditional update values
- Create geometrys for each dataset location
update dataset
set geom = ST_SetSRID(ST_MakePoint(t.long, t.lat), 4326)
from (
select id, longitude as long,
latitude as lat from dataset) as t
WHERE t.id = dataset.id;Aditional queries
- Search by date interval
SELECT * FROM dataset WHERE date_time::date >= date '2008-02-02' AND date_time::date < date '2008-02-03';
