Description
This GIS data layer comes from the partnership approach GeoBretagne and in particular the Orthophotography and MNT business cluster.
The orthophotography and MNT business cluster is a working group that aims to bring together stakeholders interested in a shared acquisition of aerial orthophotography and a digital field model (MNT).
It is organised with departmental business centres which, depending on the acquisition schedule provided for in orthophotographs, evaluates the technical specifications and manages tenders and partnerships related to acquisitions.
__Objectives__
The objectives of the orthophotography and MNT business cluster are as follows:
• acquire and finance orthophotography and precision free of rights MNT in the regional territory,
• organise the wide dissemination of this data,
• widening the problem to include satellite data and derived data.
