Do you need to import data after equipping a Telecoms GIS (geographic information system)? Be sure to verify data consistency with a range of controls. In this infographic, we explain the risks associated with data inconsistency and the reasons inspection is important.
The need for Telecoms GIS data verification
There are three reasons it is imperative that you inspect data to import into the newly implemented Telecoms GIS:
- Inspection prevents the database from becoming corrupted. Errors are commonplace when importing big data into a geographical information system. Inspecting the nature of data helps prevent these errors from having an impact on the database or worse still, on operations.
- Confirm the network entered into the GIS system. An inspection is not superfluous once the telecoms network has been integrated. The goal is to ensure no entry error is present and that service provider deliveries to clients have been taken into account.
- Ensure work database consistency. To facilitate collaboration between the project’s many parties, it is imperative that the information present in the database be reliable.
What inspections are necessary?
Depending on your specific requirements, a variety of SIG Telecom data type inspections can be done:
- Formalism verification. This means checking that codes or certain fields are unique from one another, that the proper data encoding and field format have been used.
- Attribute completion checks. Completion of attribute fields is not always necessary—it depends on FTTH project deployment. Be sure you check that all required fields have been completed.
- Geometry checks. Multiple errors can occur when dealing with databases: null lines, topological blockages between cables and node extremities, non-compliance with the coordinate system, incorrect positioning of subscriber points in the structure, and so on.
- Consistency checks between tables and fields. That means checking that the proper equipment is connected to technical points, that fiber numbers do not exceed the cable module, etc.
- Engineering rules. The rules announced in a CCTP must be followed to the letter. That is why it is essential to check the equipment type in rooms, to verify the dimension and capacity of cables according to the size of their infrastructure, to ensure consistency between actual and cartographic cable length, and to detect isolated points.
The data imported into your Telecoms GIS will be pivotal for any future operations. Are they reliable? Are they error-free? These are just some of the questions you will need to answer when inspecting multiple orders. This in turn offers the best guarantee of optimal working conditions.
