During the research of FACC for AFAYBIS project,
DIGEST, S-57, German ALKIS-ATKIS-AFIS catalogue,
New Zealand ESA, South Africa, Iceland, Austria, and
Malaysia catalogues are examined.
In this manner, FACC of AFAYBIS is prepared using the
ISO 19110, TABIS, other country and international
institution's approaches, and they are taken as
consideration for the design.
AFAYBIS FACC includes the features which can take
part of designed spatial data set, feature attributes,
relationships, operations, definitions and descriptions.
The basis level of the classification in the catalogue is
feature, and it is available in digital form. Nevertheless,
all the features, operations of features, attributes of
features and relationships are defined with a unique
name.
4.1.2 Metadata: ISO 19115 Metadata standards are taken
as base for AFAYBIS project. Metadata is utilized to
describe the geographic data.
4.1.3 The Parameters of Projection and Datum: In
AFAYBIS project, most of the used data is produced in
European 1950 (ED 50) geodetic datum. 1/1000 and
1/5000 scaled existing maps are produced with 3° UTM
parameters. Since the 30° eastern central meridian is very
close to Istanbul, 3° wide zone is used for the maps.
Therefore, the errors in 3° wide zone maps are less than
6° wide zone maps. 27' eastern meridian is taken as
central meridian for part of Municipality of Silivri
administration boundary and around Municipality of
Catalca boundary (IBB, 2003).
The core data of AFAYBIS project is 1/1000 scaled.
Those data was produced using photogrammetrical
methods by Istanbul Metropolitan Municipality in
adjacent area, and related parameters are used which is
explained above. The data is up-to-date for 1997- 1999
years. In the beginning, other data than the core data will
put into the system by taking those data as reference.
However, if the INSPIRE and TUTGA (Turkish National
Fundamental GPS Network) projects are accepted, all the
data will be converted into these standards, and the
updates will be applied easily.
4.1.4 Quality and Time: There will be two types of data
transfer in AFAYBIS. Most of the data is the existing
data which has been produced for years in Turkey, bereft
of quality with the exception of some quality
components. There might be structure for international
quality for updating, after the system establishment.
The temporal changes of data will be solved by
versioning and attributes.
Both the data groups will take place in the metadata
records of data set.
4.1.5 Data Exchange: GML is appropriate for data
exchange according to the perspective of ISO and
INSPIRE. However, this will be valid after the system
implementation for updating and receiving the data from
the system.

4.2 The Product Standard
In general, the product standards are including the map
and screen layout view content, symbology, accuracy and
quality, documentation standards.
Reference product will be the maps in AFAYBIS. By-
product is reports etc... The quality of the map is directly
based on the existing data. Although there are several
symbols for disaster management, none of them have
international acceptance. It has been decided to use the
symbols mainly in use. There will be information about
the products in metadata.
4.3 The Process Standard
The process standard includes the process content and
documentation standards. There are software are
documentation dimensions. The general processes of
AFAYBIS project are as follows:
e Data input
e Data update
e Find and locate
e Planning
o Conventional planning: planning in
the preparation phase according to
grading results of the risk zones and
alarm degree.
o Unexpected situation planning:
planning according to the information
received from the base during
response phase
e Response data input and monitoring
In the project, application interfaces will be developed for
the entire process group. UML will be used for data
input-process- output loop of these interfaces.
4.4 The software Standard
The software standard includes the geometry, topology,
data storage structure, SQL, interoperability, web
mapping standards etc... This standard requires using
software which is appropriate for ISO/TC 211 and
OpenGIS standards.
4.5 The Implementation of GIS
There is already almost no standard for GIS
establishment. However, Rational Unified Process which
is followed for AFAYBIS, is accepted to be used in
several projects.
5. CONCLUSION
While the technology is became the top for the data
communication, the important issue has appeared to
manage the data appropriately. Nowadays, the data
management means to produce, update the
data/information in coordination, according to the
standards without duplication of data. Additionally this
procedure requires a communication infrastructure to be
appropriately structured and developed for available data
sharing and using.
As far as the importance of the data- information
exchange and share between the member and candidate
countries of EU considered, it is clear that the necessity
of preparation of the standards is inevitable.
