Import Shapefile into Oracle 10g

Step 1
Download tool Oracle Shapefile Converter at http://www.oracle.com/technology/software/products/spatial/index.html and extract it into any directory.
Open the directory correspond with your operating system (ex: directory shp2sdo_nt for MS Windows), called CONVERT_HOME.
Call the directory that contains your shapefiles is SHAPE_HOME.
Call the directory that installs Oracle 10g is ORACLE_HOME.

Step 2
1. Open console, run the following commands:
> cd $SHAPE_HOME
> set path="$CONVERT_HOME"

2. Run shp2sdo converter:

• on Windows NT

shp2sdo.exe <file_name> <table_name> -g <geom_name> -d -x (<minx>,<maxx>) -y (<miny>,<maxy>) -s <SRS> -t <tolerance> -v

• on Sun Sparc Solaris or Linux

shp2sdo.exe <file_name> <table_name> -g <geom_name> -d -x \(<minx>,<maxx>\) -y \(<miny>,<maxy>\) -s <SRS> -t <tolerance> -v

Ex:
shp2sdo.exe tuyendg spa_tuyendg -g geom -d -x (575977.125,577368.125) -y (1195219.125,1196522.0) -s 32648 -t 0.5 -v

Note: Type shp2sdo.exe -h for help.


Step 3
After running shp2sdo converter, it creates 2 files:

• *.sql : to create oracle table.

• *.ctrl : to store data.

1. Open iSQL*Plus with database that you want to import, execute the content in *.sql (ex: @spa_tuyendg.sql).

2. Open file *.ctrl, insert line " CHARACTERSET UTF8" after line "LOAD DATA" and save it.

3. Open console, use Oracle SQL*Loader by running the following commands:
> set path="$ORACLE_HOME/product/10.1.0/db_1/BIN"
> sqlldr <username>/<password> <table_name>
Ex: sqlldr SYSTEM/oracle spa_tuyendg


Step 4
Open iSQL*Plus, execute the following commands:
CREATE INDEX <index_name> ON <table_name>(<geom_name>) INDEXTYPE IS MDSYS.SPATIAL_INDEX;
EXECUTE SDO_MIGRATE.TO_CURRENT('<table_name>','<geom_name>');

Ex:
CREATE INDEX spa_tuyendg_spatial_idx ON spa_tuyendg(geom) INDEXTYPE IS MDSYS.SPATIAL_INDEX;
EXECUTE SDO_MIGRATE.TO_CURRENT('SPA_TUYENDG','GEOM');

Import spatial data (shapefile) into PostgreSQL

1. Open console, execute following commands:
cd $ShapeDir
shp2pgsql -W UTF-8 <filename>.shp <schema>.<tablename> ><filename>.sql

2. Open file that has just created, insert string "WITH OIDS" before character ";" of command CREATE TABLE, and then save that file.

3. Continue to execute the command:
psql -h <hostname> -U <username> -d <databasename> -f <filename>.sql

4. Open pgAdmin3 (or phpPgAdmin), open Query Tool and input following lines:
CREATE INDEX <indexname> ON <tablename> USING gist (<spatial_attribute>);
VACUUM ANALYZE <tablename>

Ex:
shp2pgsql -W UTF-8 hcm_road.shp public.hcm_road > hcm_road.sql

psql -h 127.0.0.1 -U postgres -d hcmcity -f hcm_road.sql

CREATE INDEX hcm_road_the_geom_gist ON hcm_road USING gist (the_geom);

VACUUM ANALYZE hcm_road

* Note: if you want to export data from PostgreSQL to shapefile, using command pgsql2shp.

Install PostgreSQL 8.2 with PostGIS on Ubuntu

On Ubuntu 7.10
Open console, execute following command:
sudo apt-get install postgresql-8.2 postgresql-client-8.2 postgresql-client-common postgresql-common postgresql-server-dev-8.2 postgresql-contrib-8.2 libgeos-dev proj postgis postgresql-8.2-postgis

Note: /usr/lib/postgresql/8.2/lib ---> directory contains file liblwgeom.so


On Ubuntu 7.04
1. Open console, execute following command:
sudo apt-get install postgresql-8.2 postgresql-client-8.2 postgresql-client-common postgresql-common postgresql-server-dev-8.2 postgresql-contrib-8.2 libgeos-dev proj flex postgis

2. Download postgis-1.3.x.tar.gz and decompress.

3. Execute following commands:
cd ${postgis-1.3.x}
./configure

Cài đặt xvnkb trên Ubuntu

1. Cài đặt các package :
sudo apt-get install build-essential
sudo apt-get install xorg-dev

2. Download xvnkb-0.2.9a.tar.bz2 và decompress.
3. Thực hiện các lệnh sau :
cd xvnkb-0.2.9a/
./autogen.sh
./configure --use-extstroke

4. Sửa file config.h :
gedit config.h

thành :

#define __VK_CONFIG_H
#define VK_CHECK_SPELLING
#define VK_USE_EXTSTROKE
#define VK_NEED_UCHAR

(bỏ đi một vài dòng bị lỗi)

5. Compile & Install
make
sudo make install

6. Nếu muốn xvnkb tự động chạy lúc khởi động, bạn vào menu System > Preferences > Sessions, chọn New và nhập vào ô Command như sau: xvnkb --method=telex --charset=utf8 (trong đó method là telex, vni hoặc viqr; charset là utf8, tcvn, viscii, vps hoặc viqr). Bây giờ xvnkb sẽ khởi động mặc định với kiểu gõ (method) và bảng mã (charset) mà bạn đã chọn.

Get UTF-8 string from file *.properties to web page

Để lấy được chuỗi utf-8 từ file *.properties thì file đó phải thỏa các điều kiện :
- Định dạng của file là utf-8.
- Chuỗi nhập vào file là utf-8.
Từ file *.properties, ta dùng câu lệnh native2ascii trên console hoặc dùng thẻ native2ascii của Ant để chuyển các chuỗi utf-8 về dạng mà trang web có thể đọc được.
Ví dụ : Chào mọi người
--> Ch\u00e0o m\u1ecdi ng\u01b0\u1eddi

1. Dùng câu lệnh native2ascii trên console :
Cách dùng như sau :
native2ascii -encoding utf8 sourcefile destfile
Nếu destfile không có thì nó sẽ đè chồng lên sourcefile.

2. Dùng thẻ native2ascii của Ant :
Cách dùng như sau :


Thuộc tính ext là tùy chọn, dùng để thêm phần mở rộng (extension) của tên file cũ. Chỉ khi nào thư mục src trùng với thư mục dest thì phải có thuộc tính ext để tạo 1 file mới.

Ví dụ :


--> Kết quả trả về file : messages_en.properties
