Nature of the offer
Use GeoCassini to have the digital twin of your territory, by subscription, from 1 euro per km per month.
What does the territory digital twin contain in Geocassini?
In the basic offer, the digital twin of territory is produced by a cloud of 3D colorized points with centimeter precision produced by the lidar process. The absolute precision is 3 to 5 cm in x,y,z and the relative precision of 1cm in the same area.
The offer can be enriched
• by the 180° or 360° photos taken during the lidar acquisitions
• by additional aerial lidar coverage of the area concerned.
This lidar coverage includes at least 40 points per m² with an accuracy of less than 15 cm in x,y and less than 10 cm in z.
To note It is quite possible to mix terrestrial lidar data with IGN aerial lidar data (20 points / m²) available in
Open Data under GeoCassini.
Example : extract of the general view of CHOLET (49)
How does the offer work ?
• The offer is intended for any GeoCassini CLIENT with at least one EXPERT subscription.
• Pricing is based on:
– the number and nature of the GeoCassini subscriptions opened by CLIENT
– the content desired by the CLIENT (terrestrial point clouds, panoramic photos, additional LIDAR coverage)
– the length of tracks concerned for land acquisitions
– the surface concerned for aerial coverage
– the duration of the subscription
• Updates are managed contractually
Example : view place TRAVOT (CHOLET)
