This workflow includes

• the producers of the basic data
• all the traditional players who operate it (design offices, construction companies, community technical services, …),
• new players in the use of this data (infra networks, connected objects, asset managers, technical data platforms (DT / DICT), urban models, open data, augmented reality, mixed reality)
• those involved in updating the data
  The traditional “topos points” are often replaced by point clouds from lidar surveys.
  The acquisition is much faster, the data produced is precise, dense and comprehensive.
  Their uses go beyond the simple topographical plan. The latter has less and less existence on its own; it is akin to a property of consumption, as opposed to point clouds which constitute a real resource.
• If it is established to design a project, the latter, completed, makes it obsolete.
• The advent of “simplified plans” calls into question its legitimacy.
• Network detection surveys are most often summarized in wire shape files.
