Detection of buried networks and georeferencing

Augmented reality

Augmented reality in the field is gaining precision and stability. Developers are now using a precision GPS connected to their tablet and the RTK signal from the Orpheon network to display a 3D model directly at the place of use or construction at 1:1 scale.

Augmented reality more precise and stable thanks to centimetric corrections

This augmented reality is integrated directly into the images captured by the tablet’s integrated camera, live and allows excellent immersion which multiplies the projection capacity of field professionals or investors by putting them face to face with the various invisible underground elements such as buried networks or projecting their projects into reality. Augmented reality gives them a good overview of the integration of projects within existing architecture or of the constraints of the close environment by showing what is difficult, if not impossible, to move.

In addition, it is possible to interact from the screen on the projected 3D model and to take advantage of many features integrated into these applications, which also offer a wealth of additional information, judicious notes and many other contents that enrich the project.

In industry too, augmented reality is becoming an excellent way to promote a project: factory, production line, products.

Orpheon brings precision and stability

The centimetric precision provided by the use of a precision GPS associated with the RTK correction signal from the Orpheon network then becomes essential and greatly facilitates the tasks of developers. Objects integrated in augmented reality are thus very quickly and correctly placed in the projected space without oscillation.

A Full GNSS network: one step ahead

Our customers connect to our NRTK real-time corrections services with their GNSS-compatible equipment and take full advantage of the new Galileo and BeiDou corrections in addition to traditional GPS and Glonass. The addition of these very many additional satellites brings more precision and availability even in the most difficult conditions of use..  (voir article 22 Operational Galileo Satellites accessible with the Orpheon network)

Democratization of technology

The arrival of high-performance and rugged tablets or smartphones with increased autonomy, but also the democratization of precision GPS favors the emergence of many projects to which the Orphéon network responds perfectly.

Declaration of work near buried networks (DT DICT)

The work planned near pipelines and buried networks must be declared to their operators, before their execution, by means of the declaration of project of works (DT) by the client, and the declaration of intent to start work (DICT) by the contractor. Any declaration must be preceded by a consultation of the one-stop shop, accessible online, which lists all the networks present in the territory.

Simplified street plan (PCRS)

A single base plan for work near sensitive underground networks.

The role of topography in a GIS is to serve as a reference and support layer for a large number of application domains. It is an instrument at the service of the management and development of the heritage of communities.

• Its value is based on its ability to be shared and on the multiplicity of uses of each of its actors.
• It is limited to the most useful objects but it in no way sacrifices centimetric precision, which guarantees the accuracy of the information and its subsequent reuse.
• It is defined by accuracy class within the meaning of the 2003 decree and not by a scale of representation.
• It has no business content.
• Study plans and projects may use this base.
• It must meet the objectives of the reform of DT-DICT by allowing dematerialized exchanges during receipts of DT or DICT.
• Its constitution is at the initiative of the community within the framework of pooling between the network managers and the communities. It is maintained by the community.
• It is in line with the recommendations made by the CNIG within the framework of the large-scale reference system in dense urban areas (RGE ZUD).

The PCRS nomenclature describes the apparent boundaries of the road.

• It is a list of objects characterized by their accuracy class which replaces the concept of traditional topographic map:
• The final representation of each object is specific to each application and can refer to a symbol specific to each user, however a default representation will be defined.
• The consistency guarantee is based on the accuracy class to which all survey operations are necessarily attached.
• The attribute data accompanying each object of the PCRS will contain at least the genealogy of its acquisition (date of creation, origin, type, survey or resulting from transformation). Other attribute data may characterize each object (e.g. nature of the boundary: tar, low wall, etc.)
• This nomenclature lists only the necessary and sufficient objects constituting a base.
• Objects are defined in X, Y and Z.
• In this PCRS, there is no data existing elsewhere such as the business data of network operators (flush) or existing data in national databases (single cadastral parcel representation RPCU, national address database BAN). These external data can be viewed using appropriate processing (eg shifting the name of the routes to facilitate reading) and by geo-referencing (RGF93).

The PCRS alone may sometimes prove insufficient for certain operations when more detailed and precise information is required. This is why some municipalities are tempted to go even further in the process, by directly adopting a very large-scale reference system (RTGE), to make it possible to increase the security of interventions on the networks, but also to facilitate the interoperability of data between structures.
