1. Introduction and background
The managers of Natura 2000 sites are currently confronted with changes to their areas due to
anthropogenic as well climatic impacts. Habitat compositions are changing following a changing
climate and modifications in land use. Nature conservation strategies have to understand those
changes as in order to be able to react appropriately.
In the HABIT-CHANGE the project consortium developed scenarios and indicators that help to
describe this change, its drivers and effects. The aim of the project is to evaluate existing
management strategies is to provide nature park managers with
This technical documentation provides a step-by-step guide how we designed and set up the IT
infrastructure for this Decision Support System. See: http://webgis.eurac.edu/habit/
2. User Requirements
Open Source Software:
>Apache Webserver
>MySQL database
>PHP scripting language
It is the most widely used software for the development of Web applications.
The Apache Friends project has bundled these software in a package called XAMPP, to make it more
comfortable. Everything is pre-configured and ready to use, just download, install and start.
http://www.apachefriends.org/en/xampp-windows.html
There are also versions for several Linux distributions, a Mac OS X “beta” version (first steps of
development), as well as a smaller portable version, called XAMPP Portable Lite. (up to this date just
for Windows)
With the Portable Lite configuration it runs from your removable media. You can use it on your USB
flash drive or your external hard drive. You can download it here:
http://www.apachefriends.org/en/xampp-windows.html#646
[4]
After the installation is complete, you will find XAMPP under Start | Programs | XAMPP. Or when you
decide to use the portable version, please go to the folder where you unzipped it. (e.g.
C:\xampplite\xampp-control.exe)
You can use the XAMPP Control Panel to start/stop all server and also install/uninstall services.
If the Apache Webserver is started (green color), type “localhost/xampp” in a new browser tab.
(Firefox,Chrome are recommended) to see it online and the status of their components.

3. Data sets
The DSS web application communicates with database tables. As mentioned before a MySQL
database is used and needs to be filled.
Please download these 4 Excel (csv) files
http://webgis.eurac.edu/habit/doc/habitat.csv
http://webgis.eurac.edu/habit/doc/pressure.csv
http://webgis.eurac.edu/habit/doc/impact.csv
http://webgis.eurac.edu/habit/doc/response.csv
Every file contains the data records of a specific database table.
(respective “Habitat”, “Pressure”, “Impact” and “Response”)
4. Database – Design and set up
Now go to “localhost/phpmyadmin”. You will see the web database management tool of the MySQL
database called phpMyAdmin. Click on the Database tab in the main menu.
Create a new database by typing “habit_change_dss”, also define the character encoding with
“utf8_general_ci”. (see attached picture)
Press the “Create” button.
[6]
Select the just created database by choosing “habit_change_dss” from the left menu.
Now the tables of the database have to be generated and filled with the information of the
downloaded excel files.
(important: this example assumes that all excel files are stored in C:\Test)
Click on the SQL tab in the main menu:
Copy the SQL statements below into the SQL query window (see picture)
Press the “Go” button. Do this procedure for every single table.
CREATE TABLE habitat
(
habitat_id int not null primary key auto_increment,
habitat_level1 smallint,
habitat_l1_desc varchar(200),
habitat_level2 smallint,
habitat_l2_desc varchar(200),
habitat_type char(5),
habitat_type_desc varchar(200)
);
LOAD DATA LOCAL INFILE '/Test/habitat.csv' INTO TABLE habitat FIELDS TERMINATED BY ';' LINES
TERMINATED BY '\n';

EUROPE Programme co-financed by the ERDF
[7]
CREATE TABLE pressure
(
pressure_id int not null primary key auto_increment,
pressure_code smallint,
pressure varchar(200),
pressure_type varchar(50),
pressure_subtype varchar(50),
habitat_level1 varchar(50),
created_by varchar(50)
);
LOAD DATA LOCAL INFILE '/Test/pressure.csv' INTO TABLE pressure FIELDS TERMINATED BY ';' LINES
TERMINATED BY '\n';
-------------------------------------------------------------------------------------------------------------------------------------CREATE TABLE impact
(
impact_id int not null primary key auto_increment,
impact_code smallint,
impact text,
impact_type varchar(50),
habitat_level1 varchar(50),
created_by varchar(50)
);
LOAD DATA LOCAL INFILE '/Test/impact.csv' INTO TABLE impact FIELDS TERMINATED BY ';' LINES
TERMINATED BY '\n';
-------------------------------------------------------------------------------------------------------------------------------------CREATE TABLE response
(
response_id int not null primary key auto_increment,
response_code smallint,
response_option text,
response_type varchar(50),
source varchar(50),
habitat_level1 varchar(50),
created_by varchar(50)
);
[8]
LOAD DATA LOCAL INFILE '/Test/response.csv' INTO TABLE response FIELDS TERMINATED BY ';' LINES
TERMINATED BY '\n';
The table “hpir_chains” will be used to store the Habitat-Pressure-Impact-Response (hpir-) chains
created by the user with the DSS web application.
CREATE TABLE hpir_chains
(
hpir_id int not null primary key auto_increment,
habitat_id integer,
pressure_id integer,
impact_id integer,
response_id integer,
created_by varchar(50)
);
With the table “habit_members” you can define which user will have full access to the database (can
create chains) and which user will have limited access, can just read the database.
The predefined user “guest”, will automatically have this kind of limited reading role.
CREATE TABLE habit_members
(
user_id int not null primary key auto_increment,
username varchar(50),
password varchar(50)
);
INSERT INTO habit_members (username, password) VALUES ('guest', MD5('guest'));
INSERT INTO habit_members (username, password) VALUES ('user1', MD5('pass1'));

EUROPE Programme co-financed by the ERDF
[9]
When the table import is done, you will see a database structure like in the picture above.
Now the database is ready. When you click “browse”, you can see the content of each table.
5. Web application
The last step is to copy the program files into Apache’s “Hyper Text Documents" htdocs folder.
It is located within your xampp main folder.
[10]
Please download the program files: http://webgis.eurac.edu/habit/doc/dss_webapp.zip
That’s all, now you can start the DSS web application, and start creating chains:
http://localhost/habitChange
