How to update using two tables?
UPDATE road_for_update u SET the_geom = r.the_geom FROM roads r WHERE r.rd_id = u.rd_id;

How to change a column type with Cast?
ALTER TABLE roads ALTER COLUMN class_new TYPE integer USING class_new::integer;

How to add a geometry column to a table?
EXAMPLE: SELECT AddGeometryColumn(‘public’, ‘poi’, ‘the_geom’, 4326, ‘POINT’, 2)

Changing column names with spaces?
ALTER TABLE class_aroundme RENAME "level 1" TO level_1;

Setting kernel shmmax for postgres
sysctl -w kernel.shmmax=134217728
Note: For permanent changes see /etc/sysctl.cfg11. How to backup table(s) from pg_dump?
pg_dump poi_beijing -t class -t poi_class -f $BACKUPDIR/test_$MYDATE.sql

Postgres Clients Update: Navicat and EMS

rupert — Sun, 27 Jul 2008 16:37:42 +0000

Navicat already produced some lite (free) versions for Postgres both for Windows and Mac. Browse over the feature matrix to find out which version works for you. Note that all versions allow you to edit the record which I can’t do in pgadmin3.

A quick look at EMS on Windows (VMWare) is also a note worthy client. Though the MDI interface is a bit complex, one good feature is to able to see your spatial geometry as text and the corresponding SRID immediately…

Postgres PostGis PostInstall

rupert — Fri, 06 Jun 2008 23:34:36 +0000

1. Edit pg_hba.conf

# "local" is for Unix domain socket connections only
local   all         all                               trust
# IPv4 local connections:
host    all         all         127.0.0.1/32          md5
host    all         all         192.168.1.0 255.255.255.0       md5
# IPv6 local connections:
#host    all         all         ::1/128               trust

2. Edit postgres.conf

55
56 listen_addresses = '*' # what IP address(es) to listen on;
57 # comma-separated list of addresses;
58 # defaults to 'localhost', '*' = all
59 # (change requires restart)

4. For CentOS5.1, create symbolic links:
ln -s /usr/local/lib/libproj.so.0 /usr/lib/libproj.so.0
ln -s /usr/local/lib/libgeos_c.so.1 /usr/lib/libgeos_c.so.1
ldconfig
/etc/init.d/postgresql stop
/etc/init.d/postgresql start

3. Postgis Post Install

createdb -E utf8 template_routing
createlang plpgsql template_routing
psql -d template_routing -f /usr/share/postgresql-8.3-postgis/lwpostgis.sql 
psql -d template_routing -f /usr/share/postgresql-8.3-postgis/spatial_ref_sys.sql 
psql -d template_routing -f /usr/share/postlbs/routing_core.sql

Migrating data from Postgres8.2 to Postgres8.3

rupert — Wed, 07 May 2008 00:56:28 +0000

One of my hurdles recently is migrating data from my Debian Lenny Desktop Box (Postgres8.2.7/Postgis1.3.1) to my new MacBookPro Leopard(Postgres8.3.1/Postgis1.3.3). I found it out the hard way by inspecting the dump files manually. Here are the results:

1. I strongly suggest if you have a big dump file (mine is 500MB) to split the schema from the data.

pg_dump -C -s -h 127.0.0.1 -U lbs -W beijing > beijing_20080507_schema.sql
pg_dump -a -d -h 127.0.0.1 -U lbs -W beijing > beijing_20080507_schema.sql

2. pg_dump from an 8.2 would have statically linked liblwgeom to /usr/lib/postgresql/8.2/liblwgeom. You should change that to whereever your liblwgeom resides, mine is on /usr/local/pgsql/lib/liblwgeom. Just do a simple search and replace using vim on your file_schema.sql

3. After editing the schema, we can now restore the structure of the database. Check for errors and manually update the schema if needs be.

psql -h 127.0.0.1 -U beijing_4326 < beijing_20080507_schema.sql

4. Ok, so now we have the structure ready, we can also check this from pgAdmin3. Have a good look on the functions and table structures if they are fully restored.

5. Let’s load the data.

psql -h 127.0.0.1 -U beijing_4326 < beijing_20080507_data.sql

Installing PostGres8.3 and Postgis1.3.2 on Windows

rupert — Tue, 04 Mar 2008 00:15:05 +0000

It seems very nice for the new PostGres8.3 installer to bundle up third party libraries installation with the new admin pack feature. Using this feature, you can install PostGis, nPgsql, etc. The installation was painless and smooth this time. I have to backup all my data though using pg_dump.

To lessen the learning curve on installing PostGres + PostGis together, I made a short flash movie here. There is no audio in the tutorial. The idea was to introduce PostGres to my Chinese staff. I have to remove PostGreSQL 8.2 first before installing 8.3.

Installing R on Windows and Debian

rupert — Fri, 16 Nov 2007 01:15:59 +0000

‘R’ is a statistical package. For an overview, please go to www.r-project.org
My intention was to remove the point outliers from a given set of point geometries.

I just recently installed R both on my Windows XP and Debian. Regina’s www.bostongis.com is an excellent tutorial in getting involved with R. I do suggest you head first to PLR Part 1: Up and Running with PL/R (PLR) in PostgreSQL: An almost Idiot’s Guide to get you started.

The install instructions for Windows works flawlessly. I have to hold back to R-2.5 though as I plan to use RPy (Python for R), see details below. To install ‘R’ in Debian, there’s a couple of settings that we need to take care of…

1. Install r-base
sudo apt-get install r-base

2. Install plr on postgres
sudo apt-get install postgresql-8.2-plr

3. Using R in a database
psql -d beijing -U lbs -h 127.0.0.1 < /usr/share/postgresql/8.2/plr.sql

4. Set the R_HOME environment variable
/etc/postgresql/8.2/main/environment
R_HOME='/usr/lib/R'

5. Restart Debian.

RPy, R for Python, is another alternative to use R in Python. I installed it both in Windows and Debian. Note that I reverted to R-2.5 on Windows to be compatible with RPy. For Debian, Im currently using R-2.6.

For the Windows Binary Installation,

1. Read the RPy Main Site

2. Install prerequisites:

- NumPy
- Win32 Extensions Download

3. Afterwards, install the main package, RPy Download

In Debian, its a straight forward…sudo apt-get install python-rpy

Switching Back and Forth in MySQL and PostGres

rupert — Fri, 02 Nov 2007 09:12:53 +0000

There is no way I could accomplish better data manipulation between MySQL and PostGres without Navicat. Just to be clear, I do not work for Navicat. These tools were able to help me export data out of MySQL and import it to PostGres. It is just one of those products that really deserve credit.

Take note though that you can not see the “messages” displayed by the “raise command” in PL/PGSQL when using Navicat 8 for PostGres. I have to switch back to using pgAdmin III or my standard command line.

Exporting from Postgres to Mapinfo

rupert — Mon, 27 Aug 2007 12:00:36 +0000

I had a problem when using ogr2ogr and converting a postgres table to a road table. My postgres table containa a utf-8 road name which is all in chinese. The mapinfo road table created by ogr2ogr seems to contain the correct geometry and other fields that is in utf-8. However, all my chinese characters is all messed up. So, I have to export the file and open it to mapinfo.

1. In Postgres, to export to a file..
cybersoftbjv1=# set client_encoding = gbk; SET cybersoftbjv1=# \o road.txt; cybersoftbjv1=# select rd_id, cn_name from roads where cn_name <> ''; cybersoftbjv1=# \q

2. Open the file in vim, and do a “%s/ //g”. This would replace all ” ” to “”.
Note: This is reasonable for chinese since chinese dont have spaces. However english prases and sentences differ.

3. Open the file in mapinfo and replace the other columns using Table -> Update.

If anybody has any other way to specify the client encoding in ogr2ogr that would be perfect…

Creating Road Topology

rupert — Wed, 22 Aug 2007 12:40:35 +0000

Im trying out ways to create a topology of edges and vertices for a road network. Currently, there are three ways I know of:

1. Using ArcGIS build coverage line.
– This includes the use of ArcGIS. Exporting the feature into tics, arcs and nodes, then afterwards assembling them all together. Its functional but have not fully tested the quality of the road topology. Also, assembling them back together through the spatial objects comparison will take some time. It would be better *If* ArcGIS could create the nodes wrt to the base table.

2. Using PostGres, postlbs functions.
– Use of SELECT ASSIGN_VERTEX_ID(‘table_name’, double_precision_distance. So far this bails on me on my first test on my win-xp laptop. We can test this on Linux if the response is the same.

3. Using Mapinfo Basic Scripts provided by J.
– Haven’t gone indepth with these for now, but looking forward to it.

4. Using Grass
– As documented in pgrouting.postlbs.org site’s Topology Creation

CF-Postgres ODBC Connection

Buffering points

rupert — Sat, 07 Jul 2007 16:52:43 +0000

Here is a post in buffering points and combining them using GeomUnion. Works in GEOS3.0.0, so note that your POSTGIS installation in windows contains a lower version of GEOS.

DROP FUNCTION combineGeometry();
 
CREATE FUNCTION combineGeometry() RETURNS Void AS'
DECLARE
	--define datatypes here
	updateCount integer DEFAULT 0;
	geom_record RECORD;
	geom_current RECORD;
	geom_final RECORD;
	mytotal integer DEFAULT 0;
 
BEGIN
 
	--get the total
	SELECT count(*) as mycount FROM busstopv1_buffer_20_temp INTO mytotal;
 
	-- 1,2,3,4,5
	FOR geom_record IN SELECT * FROM busstopv1_buffer_20 LOOP
 
		--get the current geom of the record
		SELECT *
		FROM 		busstopv1_buffer_20_temp b
		WHERE 		b.gid = geom_record.gid INTO geom_current;
 
		RAISE INFO ''RECORD GID: %'', geom_record.gid;
		RAISE INFO ''===========TOTAL COUNT: %=============='', mytotal;
 
		--find the intersection of the current geom with other spatial entities
		--and loop through that. For each loop, update the geom.
 
		IF geom_current IS NULL THEN
			CONTINUE;
		END IF;
		FOR geom_final IN
			SELECT GeomUnion(b0.the_geom, geom_current.the_geom ) AS geom_current_union, b0.gid
			FROM busstopv1_buffer_20_temp b0
			WHERE b0.gid <> geom_current.gid
			AND Intersects(b0.the_geom, geom_current.the_geom) = ''t''
			ORDER BY gid ASC LOOP
 
			--geom_current.gid = geom_record.gid
			UPDATE busstopv1_buffer_20_temp
			SET the_geom = GeomUnion( the_geom, geom_final.geom_current_union )
			WHERE gid = geom_current.gid;
			RAISE INFO ''UPDATED GID:%'', geom_current.gid;
 
			DELETE FROM busstopv1_buffer_20_temp WHERE gid = geom_final.gid;
			RAISE INFO ''DELETED GID:%'', geom_final.gid;
 
			mytotal = mytotal - 1;
 
		END LOOP;
 
	END LOOP;
END;'
LANGUAGE plpgsql;
 
SELECT combineGeometry();

Next step.. trying out CGAL.

Preparing routing data for pgRouting

rupert — Tue, 10 Apr 2007 09:23:35 +0000

1. It is important that you already have postgres, postgis, pgRouting installed in your machine.

A. The schema. Below is the sample schema that is a derivative of the kanagawa sample data from pgRouting. Take note of the source and target nodes, as well as the length and the node coordinates (x1,y1; x2,y2) of the line.

cybersoftbj=# \dt
List of relations
 Schema |       Name       | Type  |  Owner
--------+------------------+-------+----------
 public | geometry_columns | TABLE | postgres
 public | roads            | TABLE | postgres
 public | spatial_ref_sys  | TABLE | postgres
(3 rows)

cybersoftbj=# \d roads
TABLE "public.roads"
COLUMN   |          Type          |                      Modifiers
------------+------------------------+-----------------------------------------------------
gid        | integer                | NOT NULL DEFAULT NEXTVAL('roads_gid_seq'::regclass)
rd_id      | bigint
yutu_id    | integer
block_id   | bigint
heirarchy  | character varying(5)
cn_name    | character varying(75)
py_name    | character varying(100)
source     | bigint
target     | bigint
x1         | numeric
y1         | numeric
x2         | numeric
y2         | numeric
costlength | numeric
the_geom   | geometry

A. Extracting the coordinates of the line segments from Mapinfo.

1. I have to format the data structure as follows…

…here is the roads table after weeding out some unnecessary columns…

… adding the source,target,x1,y1,x2,y2,costlength…

2. Using ObjectGeography. Download the MapBasic Reference

ObjectGeography( object, attribute )

ObjectGeography( object, “1″ ) <– gives you the beginning x coord of the point

3. Export the tab file to a shape file for ArchMap.

Loading Mapinfo table to PostGis

rupert — Wed, 04 Apr 2007 21:25:06 +0000

AFAIK, there are only two ways to load data to PostGIS:
1. Using Insert statements
2. Using Utilities.

Utilities include shp2pgsql which is found in “C:\Program Files\PostgreSQL\8.2\bin\” or “/usr/local/pgsql/bin”. To load Mapinfo table, I have used the OGR utilities from FWTools for Windows. and used gdal1.3.2 (since it contains ogr) for Unix.

OGR2OGR CheatSheet should be a good kickstart for basic understanding. For the impatient..

ogr2ogr -f "PostGreSQL" -nlt LINESTRING -a_srs "EPSG:4326" PG:"host=localhost user=username password=mypassword dbname=mydb mytab.TAB -select columnName

ogr2ogr -f "PostgreSQL" PG:"host=myhost user=myloginname dbname=mydbname password=mypassword" mytabfile.tab -nln newtablename -select columnName

Bear in mind that you should select out the columns from your mapfile (mine is chinese) especially if you have a diffent encoding in your column which matches your database (postgres). You might get a “Terminating translation prematurely after failed translation of layer [layername]” error. Since Mapinfo stores the text to ASCII, my workaround is to export the tabfile to a UTF-8 textfile then upload it to PostGres. Hoping the primary ids would match to make the necessary updates…

An alternative to load Chinese text from Mapinfo to PostGIS is the ff:
1. In Mapinfo use the Universal Translator to export the table into a shape file.
2. Once you have the shape file, you can directly use the shp2pgsql.

shp2pgsql -W “gbk” -s 4326 lbjrdnt_small_polyline roads > roads.sql

Creating a Spatial Table in PostGIS

rupert — Wed, 04 Apr 2007 20:06:43 +0000

Creating the spatial table from scratch…

[postgres@rupert-linux ~]$ su - postgres
[postgres@rupert-linux ~]$ createdb _E UTF-8 template_postgis
CREATE DATABASE
[postgres@rupert-linux ~]$ createlang plpgsql template_postgis
[postgres@rupert-linux ~]$ psql -f /usr/local/pgsql/share/lwpostgis.sql -d template_postgis
CREATE FUNCTION
CREATE FUNCTION
CREATE FUNCTION
CREATE FUNCTION
CREATE FUNCTION
COMMIT
postgres@rupert-linux ~]$ psql -f /usr/local/pgsql/share/spatial_ref_sys.sql -d template_postgis
[postgres@rupert-linux ~]$ psql

Alternatively you could also create your spatial table from a template…

     14 postgres=# CREATE DATABASE gistest TEMPLATE=template_postgis;
     15 CREATE DATABASE

I have also added the routing functions using routing.sql and routing_postgis.sql

[postgres@rupert-linux ~]$ psql -f /usr/local/pgsql/share/contrib/routing.sql -d template_postgis
[postgres@rupert-linux ~]$ psql -f /usr/local/pgsql/share/contrib/routing_postgis.sql -d template_postgis

FYI…

The spatial_ref_sys table contains the ESPG codes and projections. Currently it has 3162 records.

gistest=# \d spatial_ref_sys;
 srid      | integer                 | NOT NULL
 auth_name | character varying(256)  |
 auth_srid | integer                 |
 srtext    | character varying(2048) |
 proj4text | character varying(2048) |

The geometry_columns contains the geometry type of the table you just created..

gistest=# \d geometry_columns;
 f_table_catalog   | character varying(256) | NOT NULL
 f_table_schema    | character varying(256) | NOT NULL
 f_table_name      | character varying(256) | NOT NULL
 f_geometry_column | character varying(256) | NOT NULL
 coord_dimension   | integer                | NOT NULL
 srid              | integer                | NOT NULL
 type              | character varying(30)  | NOT NULL

Installing PostGres, PostGIS, pgRouting in Linux

rupert — Tue, 03 Apr 2007 15:05:09 +0000

A. Installing PostGres

A.1. Download and install the source: postgresql-8.2.3.tar.gz

[root@rupert-linux routing]tar -xvzf postgresql-8.1.2.tar.gz
[root@rupert-linux routing]LDFLAGS=-lstdc++
[root@rupert-linux routing]./configure --prefix=/usr/local/pgsql --with-perl --with-python --with-krb5 --with-openssl
[root@rupert-linux routing]make
[root@rupert-linux routing]make install
 
A.2. Post Compile Operations:
 
[root@rupert-linux routing]/usr/sbin/adduser postgres
 
[root@rupert-linux routing]mkdir /usr/local/pgsql/data
 
[root@rupert-linux routing]chown postgres /usr/local/pgsql/data/
 
[root@rupert-linux routing]su - postgres
 
[root@rupert-linux routing]/usr/local/pgsql/bin/initdb -D /usr/local/pgsql/data/

Note: If youre default locale is not EN, say chinese, then you would get:

The files belonging to this database system will be owned by user “postgres”.
This user must also own the server process.

The database cluster will be initialized with locale zh_CN.GB18030.
initdb: could not find suitable encoding for locale “zh_CN.GB18030″

A.3. Edit environment variables. Add the ff to your .bash_profile

[root@rupert-linux routing] vi /root/.bash_profile
PATH=$PATH:$HOME/bin:/bin:/sbin:/usr/bin:/usr/sbin:/usr/local/bin:/usr/local/sbin:/usr/local/mysql/bin:$JAVA_HOME/bin:/usr/local/pgsql/bin
export PGLIB=/usr/local/pgsql/lib
