A
bstract: Use of the Romanian position determination (ROMPOS), a new option for a new generation of
information systems using geo8spatial information. Data provided by the Romanian position determination
system (ROMPOS) could be used in various applications such as positioning and monitoring of still or moving
objects, in navigation, measurement of surface irrigation, environmental protection, transportation, etc. This
new approach introduces the concept of handling the problem of GIS support decision making involving
handling of satellite images in order to facilitate access to decision makers to discover, access and integrate
geospatial information in decision making, many fields and research. A very useful application is to manage
environmental risks and pollution factors with different substances, soil, air, water and other factors, but also
for competitive management for decision makers at central and local levels in various problems that are
encountered in many environmental projects in our country.

1 Introduction
The Romanian position determination (ROMPOS)
opens a new option for information systems using
geospatial information. Data obtained through the
Romanian position determination (ROMPOS)
could be used in various applications such as
positioning and monitoring of still or moving
objects, project management and naval aviation,
surface measured, irrigation, protection
environment, transport, etc.
New approach to current problems can introduces
the concept of handling GIS support
decision8making, including a geo8spatial image
manipulation to facilitate access to decision
makers purchase, access and integration of
geospatial information in scenarios involving
decision making knowledgeable in many areas of
research and activity at local and central level,
European or global. A very useful application is
the management of the risks involving
environmental factors and pollution of various
substances that affect the soil, air, water and other
factors, but also made in terms of management
competitive for making bodies of decisions at local
and central level on various issues that are
encountered in many environmental projects and project management in our country, but in Europe
and elsewhere.
Aspects of position determination system
ROMANIAN (ROMPOS).
Recently, the National Agency for Cadastre and
Land Registration (ANCPI) included among its
projects to modernize national geodetic GPS
network, a position determination Romanian
(ROMPOS). Because currently, I8surătorile are
using modern services position determination, and
it is based on satellite positioning technologies,
GNSS (Global Navigation Satellite System),
National Agency for Cadastre and Land
Registration (ANCPI) through the Department of
Geodesy and Cartography, bought and installed a
set of such devices, forming a network of
permanent geodetic measuring stations, also
known as permanent GNSS stations (GPS). The
permanent stations are equipped with antennas
GNSS receivers that are capable of receiving
GNSS signals, including, in particular,
NAVSTAR8GPS (USA) and GLONASS (Russia),
and in the future will include also the positioning
system and European Galileo and global
positioning system in China, COMPAS, etc. [2].

In a first stage, between 2004 and 2008, these
positions were only used for placing and
maintaining the European reference system
(ETRS89) using the GRS880 ellipsoid, which
became official in Romania, in 2009, in addition to
the old coordinate system S842, using the ellipsoid
Krasowski, and applications for determining the
position of the post8processing mode. Based on the
National Network GNSS Permanent Stations
(RN8SGP) 8 Class [12]
During a second phase of development of
RN8SGP, after September 2008, the system went
from providing data for post8processing
positioning positioning in real time. The
integration of post8processing and real8time
positioning systems, ANCPI completed
determination Romanian positioning system called
ROMPOS.

2.System features Romanian position
determination ROMPOS
Characteristics Romanian position determination
system, generically called ROMPOS.
ROMPOS system relies on a national network of
permanent GNSS stations (GPS + GLONASS),
installed by the National Agency for Cadastre and
Land Registration. Base stations operate all the
time, 24 hours out of 24, and provides real8time
data and also the data were collected at
predetermined intervals (1 hour, 24 hours) [12].
♦ reference stations are interconnected, including
the borders of neighboring countries that have
national GNSS networks[25] [26] [27] [28] [28].
♦ location of reference stations were chosen so as
to ensure long8term stability for GNSS antennas
and signal reception. Location and receivers are
chosen to provide "visibility" of the horizon, free
from obstacles where possible, to avoid potential
sources of interference and multipath effects.
Using properly calibrated antennas can reduce
multipath effects, the new generation antennas,
which were purchased by ANCPI in 2008 were
calibrated using the best techniques available
worldwide (individual absolute calibration for
each antenna), [18];
♦ reference stations using only receivers and
antennas with dual8frequency, geodetic class;
♦ stations continuously receive data from satellites
NAVSTAR8GPS (all channels) and the Russian
GLONASS satellites (over 36 stations). Once
Galileo is operational, it will be mandatory for all
permanent positions using data from satellites of
the system and the only optional NAVSTAR GPS
and GLONASS satellites; ♦ permanent station coordinates are determined
with high accuracy (less than 1 cm) in ETRS889
reference system (European Terrestrial Reference
System 1989), by increasing the density of GNSS
stations (Bucharest, Bacau, Baia Mare, Constanta
Deva), embedded in the European Network of
Reference (EUREF), [5].
♦ Positions antennas reference stations are checked
periodically to detect any possible changes due to
tectonic movements and from other factors;
♦ A quality management system will be
implemented in order to help users to achieve the
expected results in accordance with the
requirements for accuracy, integrity, and
availability of the system. A minimum of 99%
availability and integrity will be guaranteed. Cases
of failures, interruptions and low quality will be
identified automatically in real time and treated as
soon as possible [5].
♦ national reference stations are compatible with
most other GNSS systems type. The national
system will ensure that it is interoperable with the
European System EUPOS similar.
The Romanian position determination (ROMPOS)
ANCPI is provided for all users, through the
National Center for Services ROMPOS.
National Center ROMPOS Services was
established in the Department of Geodesy and
Cartography 8 Service for Geodesy and replaced
RN8SGP Monitoring and Control Center. RN8SGP
Monitoring and Control Center was designed to
monitor and control the activity of RN8SGP for the
automatic transfer of data recorded at stations to a
central database server. The data consisted of
records transferred from NAVSTAR8GPS and
GLONASS satellites with different rates (1S, 5S,
30 seconds), and were used to determine the
positions of post8processing mode, and now the
service ROMPOS real time [7] [8] [9] [10].
This service is extremely necessary for projects
related to project management, sustainable
development and environmental protection.

Data obtained through this service is useful and
can be integrated into a geographic information
system (GIS) data with remote sensing,
photogrammetry and classical data are acquired
with total stations[12], [13], [14], [15], ], [19].

3. Environmental protection and
sustainable development projects in
urban areas.

General issues on environmental protection and
sustainable development projects in urban areas.
In urban areas, environmental protection and
sustainable development projects must be
managed properly because resources are limited.
These issues cause a number of issues such as:
• urban authorities should know that land is
available for development, the legal aspect to
occupy a piece of land, and what are the conditions
and rights to do so.
• urban authorities need to know how to use the
land, you must know the location, type and sources
of income.
• urban authorities need to know the exact location,
use, condition and value of the buildings, and also,
they need to know where and what land is available
for expansion in the near future.
• Lack of accurate information on land, buildings,
natural resources and result in increased revenue
unplanned settlements, poor quality of service to
citizens, low income and poverty for local citizens.
[9]
The duty of a working group to discuss the draft
environmental and sustainable development
projects, research and formulation of projects and
action plans to solve a specific problem. In order to
collect, organize and use a lot of information
necessary for the planning and implementation of
environmental issues, a GIS is an obvious tool to
be used in the central and local decision8making
[8] .
Environment and better conditions of life of the
people in the cities and the immediate objective of
any project is that as soon as possible, cities and
towns will be able to identify and prioritize issues
and to formulate and implement policies for
sustainable development in partnership with other
parts of the public sector, private sector and the
wider community.
Information in any city is crucial to planning and
its management. Issues include the following
information:
 how to determine which data and information
are needed for the desired purpose,  How to get the data, if any, or how to collect and
how to store, so they are easily accessible, how to
interpret data and resolve the underlying issues
such as quality, contradictions and incomplete
data.
Other problems are: to determine what information
is needed, when and in what form, and how to
disseminate what is necessary.

4. Environmental management,
environmental protection and
sustainable development information
system in urban areas

Environmental management, environmental
protection and sustainable development
information system in urban areas is the formal
measures to capture specific information and fixed
procedures to retrieve this information. This refers
to the collection of all information relevant to
environmental planning and management process,
environmental protection and sustainable
development in urban areas [1].
Information system for sustainable development in
urban areas include gathering information about
various environmental issues with a city or town is
facing in the context of Romania's accession to the
EU and supports sustainable development and
environmental process continues to support
strategy formulation and action planning,
including mapping and data acquisition
conventional total stations, photogrammetry, and
remote sensing using GNSS technology and, not
least, refers to the collection of information
necessary to institutionalize this process [7] .
Important tips and advice on the implementation of
environmental management, environmental
protection and sustainable development
information system in urban areas.
 Appointment of a consultant based GIS. It is
clear from the activities of more than a GIS
consultant and a contractor involved in the
development of GIS. Consultants and contractors
are required in financial management, human
resources development, training, data acquisition,
public opinion, planning, project development, etc.
in order to maintain a systematic approach and
coordination, a municipality needs a general
consultant, to bring together and solve all problems
to come. [9]
 Prepare a strategy sufficiently developed
information system will be a component of
geographic information systems in cities, towns,

villages and in decision8making. An information
strategy is required to lead the development and
implementation of information systems for
different types [9].
 The strategy will establish a framework to judge
the investment in infrastructure systems that exist
and are proposed, and establish a framework for
setting priorities. It also identifies the systems and
resources to support and investment in the medium
term major technical and management policies that
determine the basic means and the rules by which
information systems will be developed and
managed are identified [10].
 failure of information technology providers to
respond quickly to changing needs, because there
is no medium and long term to see what is needed.
 Inability of users to share data due to
inconsistent data definitions.
 difficulties in maintaining and preserving
adequate basic skills to plan and introduce new
systems.
 Develop new business opportunities and
policies, making the introduction of new ways of
business processes possible, while proving access
to new and timely information.
 Better management of information resources
sharing data, changing data standards and data
definitions.
 better allocation of human, financial and
technical, in accordance with the objectives and
policies of the business.
 Efficient use of limited resources by
coordinating approach to development is done in a
logical order, using a standardized approach.
 Reducing the cost of emergency planning and
fewer opportunities that did not hit their target.

5 Conclusions
Strategy implementation of environmental
management, environmental protection and
sustainable development information system in
urban areas, will manage to correct many problems
in terms of implementation and to create support
and request information from the central and local .
Internal and external collaboration is very good
and necessary for the implementation strategy of
environmental management. This is possible
through a local consultant and well8organized
central coordinates the GIS, GNSS, and
technology ROMPOS. There are still many
challenges ahead, but the collaboration of all
stakeholders and the public8private partnership
should be maintained and should coexist on these
environmental projects. References:
