2. Current status of the EGNSS adoption in Mapping (1/2)
EGNOS is providing free accuracy improvement that is widely available
GNSS provides an efficient technology for mapping and are widely used by organisations such as utility companies as well as regional and local authorities.
The use of GNSS in mapping often means services with centimetre level accuracy and substantial costs (e.g., infrastructure, equipment, software, service)…
EGNOS can contribute to the growth of the GNSS use by reducing those costs… g

3. Current status of the EGNSS adoption in Mapping (1/2)
EGNOS is providing free accuracy improvement that is widely available
For many mapping applications meter level accuracy is sufficient
Applications such as thematic mapping for small and medium municipalities, forestry and park management as well as surveying of utility infrastructures can benefit from EGNOS.
Most of the devices used for Mapping are already EGNOS-ready. Thus, EGNOS also allows more and more non-professionals to access GNSS mapping technologies g

4. Key market trends
EGNOS is gaining grounds for main users: farmers, utilities and municipalities

5. Galileo value proposition for Surveying (1/2)
Supporting technical evidence and impact areas of Galileo in mapping and surveying segments
Galileo will drive dual frequency capacity and accelerate global coverage together with GPS.
Higher elevation of satellites and their number guarantee better availability of the service worldwide
Higher contingency thanks to three in-orbit spare satellites
Positioning at locations with poor sightline of the sky will become feasible as twice as many satellites will be visible
Enhanced geometry will improve the precision of positioning
Stronger signal compared to GPS, which would be able to pass more easily through some objects, such as tree canopy

6. Galileo value proposition for Surveying (2/2)
Combined GPS-III(IIF)/Galileo dual-constellation impact
Surveying market is highly competitive
Plans for full GPS-III deployment in 2021 earliest
The more satellites the better

Combined GPS-III(IIF)/Galileo dual-constellation impact
Users using dual-frequency dual-constellation receivers will be able to start utilising the fully operational dual-frequency services by as early as 2015 (accelerated by five years); accelerated adoption of inexpensive, high-precision GNSS receivers; value of high-precision data (horizontal and vertical) is expected to reduce substantially
Mapping and surveying markets are highly competitive
New possibilities facilitated by the Galileo service will be quickly picked up by the leading manufacturers and companies
Plans for full GPS-III deployment in 2021 earliest
If initial navigation services are provided already in initial operational phase, Galileo will gain advantage to establish itself in the market
Even with GPS-III Galileo will have benefit associated with users seeing more satellites, which is particular benefit in built up urban areas

7. Areas of interest for GNSS research in Mapping and Surveying
Use of Mapping based on EGNOS will be complemented with Galileo providing benefits for Surveying
The emergence of new constellations and multiple frequencies along with decreasing device prices will open up the market of Mapping and Surveying
EGNOS to be complemented with Galileo
GNSS devices more and more accessible at lower cost (EGNOS enabled)
…and with increased performance (leveraging Galileo)
Technology trends for EGNSS
Galileo CS (HP surveying)
Accuracy, continuity
Reliability with AUT (tbc)
Resistance against multipath
EGNOS and Galileo OS DF (basic precision for mapping)
Autonomous basic accuracy solution for low cost

8. Growth by mapping and surveying application
Shipments of GNSS devices by application
In land-surveying, more and more non-traditional surveyors
In hydrographic surveying, exploitation of maritime areas increases
Examples of applications: thematic mapping for municipalities, forestry and park management, surveying of utility infrastructures…

10. Discussion
Are there Galileo enabled receivers certified for CAP field boundary measurements?
Which is the maximum internal error for the receivers imposed by EU Regulation for CAP?
Cadastral surveys are important for restoration work after natural disasters. Do you think of any other mapping application that can be used for such a situation? Can you think of other applications for Cadastral surveys?
Do you know of any initiative from mapping communities that are fostering the use of GNSS devices in their specific interests (such as Open Street Map or Google Map Maker for general purposes)?
Not yet but EGNOS is being used. The European Commission regulation (11/2009) requires the use of tools ‘of a proven quality’ for the measurement of agricultural parcels being claimed for subsides under the Common Agricultural Policy (CAP). To provide sufficient evaluation of the reliability and accuracy of GNSS receivers and ortho-images, the Joint Research Centre (JRC) issued a validation protocol for area measurements based on the ISO 5275 norm.
In the link below, it is showed the EGNOS enabled receivers for CAP field boundary measurements.
2.  The maximum internal error imposed by EU Regulation is 1.5 m
