    Yes, the use of Syslor solutions is truly unlimited. Once you subscribe, you can use the applications on all your sites, with no limit on the number of surveys, layouts, projects or users, and no credit or token system.
    Why does syslor not charge on a pay-as-you-go basis like other solutions?
    Syslor has opted for a subscription model in order to simplify the use of solutions in the field. Pay-as-you-go billing (tokens, credits, actions) complicates cost tracking and can discourage the use of tools. With Syslor, teams can work freely and continuously, without worrying about a meter, while keeping control of their budget.
    Does the subscription include access to the web portal?
    Yes, access to Syslor's web portal is included in all subscriptions.
    Does the subscription include application updates?
    Yes, application updates are included in subscriptions.
    Does the subscription include access to RTK services?
    No, RTK services are independent and require a specific subscription. Contact us for our rates.
    Does the price depend on the number of users?
    The price is the same regardless of the number of users registered on the platform (the licence is linked to the receiver).
    Data
    Where is my data stored and how is it secured?
    The data is stored on a sovereign European cloud infrastructure hosted by OVH. It is backed up securely and geo-redundantly across several separate sites to ensure its availability and limit any risk of data loss.
    How is my data organised on the web portal?
    The data is organised by company and then by project, to facilitate its management and use. At company level, the portal centralises users, settings, corrections, receivers and attribute libraries. Each project then groups together data from the various Syslor solutions (EasyField, EasyView, EasyScan, EasyMap), which can be viewed and downloaded online at any time.
    How long are my data stored?
    By default, your data is retained for a period of 10 years..
    Technology
    How does GNSS RTK positioning work?
    GNSS RTK positioning relies on receiving satellite signals corrected in real time to achieve centimetre-level accuracy. A GNSS/GPS receiver picks up signals from satellite constellations, while an RTK network provides corrections to compensate for errors and greatly improve positioning accuracy in the field.For a detailed explanation of the principles of GNSS and RTK, please see our dedicated article: Understanding the fundamentals of GNSS.
    How does photogrammetry used by Syslor work?
    The photogrammetry used by Syslor is based on video recordings made directly in the field using the EasyScan application on a smartphone or tablet. These videos are then processed to generate orthophotos and 3D models, which can be used in the Syslor portal for data visualisation and vectorisation. For more information on this subject, see our dedicated article: Photogrammetry: principles, methods and use cases.
    What is Augmented Reality applied to underground networks?
    Augmented reality applied to underground networks consists of superimposing network data onto the image of the terrain in real time. It allows the position of networks to be visualised directly on site, without reopening trenches, via a smartphone or tablet, in order to make operations safer, limit the risk of damage and facilitate understanding of the subsoil.
    How are orthophotos and point clouds generated?
    Orthophotos and point clouds are generated using photogrammetry from video recordings made with the EasyScan application. The user simply films the open trench with a smartphone or tablet. The video is then processed to produce a georeferenced 3D point cloud and a usable orthophoto, which can be accessed directly in the Syslor environment for viewing, tracing and exporting data.
    How does Syslor guarantee centimetre-level accuracy?

    Centimetre accuracy can be achieved in photogrammetric surveys carried out with EasyScan, subject to the use of ground control points.

    The solution is based on:

    • EasyScan photogrammetric capture,
    • GNSS positioning,
    • integration of control points,
    • and processing carried out according to controlled protocols.
