The object of the contract is the detection and georeferencing of networks in the context of additional investigations before work and / or in the context of precision control in planimetry and altimetry, as well as the realization of image basemaps in PCRS format as part of pre-work studies or as part of punctual updates. The goal is to precisely locate and georeference existing structures and the plan fund

it is a question of raising and making photo backgrounds in PCRS format, with the possibility of vectorization from the photos, in the PCRS standard in SHAPE format

these are digitization and/or transformation works from existing sources (background plans on paper, image support, dxf, dwg, shp?) with the aim of enriching the GIS. They may concern either drinking water networks or heating networks

it is a question of detecting and georeferenceing electrical networks (Public Lighting, Signalling, Very Low Voltage Networks, etc.) and /or other networks as part of additional non-intrusive investigations before work and of controlling the accuracy in planimetry and altimetry of the georeferencing of electrical networks and / or PCRS
