The DGPS service consists of 12 DGPS stations on the Norwegian coast. Each DGPS station has reference stations that monitor all visible satellites (over 8 degrees elevation) and calculates a correction value for each satellite. These corrections are transmitted over the Norwegian Coastal Administration's maritime radio beacon in the frequency band from 283.5 kHz to 315 kHz, and they can be received by users equipped with a DGPS radio beacon receiver. The user's GPS receiver uses the received corrections to improve the accuracy of the positioning it calculates. Within the specified coverage area for the DGPS service, the user will achieve a positioning accuracy better than 10 metres (2 drms, 95 per cent probability). Experience shows that the positioning accuracy is typically in the range of 1 to 3 metres. In addition to improved positioning accuracy, the DGPS service will also provide integrity alarms for GPS. The DGPS service should have an availability of 99.5 per cent, calculated over a two-year period. The DGPS service is linked to GPS. The Norwegian Coastal Administration, other Norwegian agencies or Norwegian authorities do not have any control over the technical and operational conditions for GPS

3. Problem Statement
 Limited Precision and Accuracy: Traditional surveying
methods relying on manual measurements and optical
instruments, often result in limited precision and accuracy.
 Time-Consuming Procedures:
 Susceptibility to Environmental Factors: Adverse weather
conditions, challenging terrains, and environmental obstructions
can negatively impact the reliability of traditional surveying
equipment.
 Human-Induced Errors:
 Cost Inefficiencies:
 Insufficient Accessibility:
 Inadequate Integration of Data: Lack of seamless integration
between different data sources and surveying tools

4. Problem Solutions
• Addressing these challenges is imperative for meeting the
evolving demands of modern development projects,
urbanization, and environmental conservation efforts.
• There is a pressing need for innovative solutions that leverage
advanced technologies, such as DGPS and DREONE, to
overcome the limitations of traditional surveying methods.
• These technologies have the potential to enhance precision,
streamline processes, and provide a more comprehensive and
accurate understanding of surveyed landscapes.

5. Justification for Project Title
• The proposed project, "Optimizing Land Surveying
Precision: Integration of DGPS and DREONE Technology
for Enhanced Geospatial Mapping," aims to tackle these
challenges head-on by integrating state-of-the-art technologies
into the land surveying workflow. Through this integration, the
project seeks to improve overall precision, reduce time and cost
inefficiencies, and contribute to a more sustainable and
informed approach to land management and development.

6. Objective of Project
• The objective of this to envisage the DGPS based survey to collect the survey data
about the natural and man-made features of the land, as well as its elevation.
• To digitize the contour map of the ground and existing features on the surface of
the earth or slightly above or below the earth’s surface.
• To generate a digital map.
• An Analysis report on carrying a DGPS survey and digital elevation model also
comparison between GPS and DGPS data.
