Questionnaire
An ad-hoc questionnaire has been designed and submitted in June-July 2023 to better understand the audience of the NAUTILUS project. Here are the questions that have been asked:
1) Are you interested in a benchmark dataset for underwater geospatial applications?
2) What is your background?
3) Which applications are you interested in?
4) What is the depth range at which your activities take place:
5) How large is the area in your typical applications?
6) What is the spatial resolution required in your typical applications?
7) What kind of data are you interested in?
8) Which geomatic techniques do you use for your project or are you interested in?
9) Which data acquisition platform would better fit your project?
10) Which of the following activities within the NAUTILUS project would you be interested in?
Here follows a brief summary of the report (download the full report).
48 People have answered the first Nautilus questionnaire (25% of the total contacted people). Everybody positively replied being interested in a benchmark dataset for UW geospatial application. The majority of the participants have an academic background (83%).
Three macroarea have been defined, based on the application domains of the participants:
A: Cultural Heritage
B: Marine ecology, biology and environmental monitoring
C: Seafloor mapping and industrial application
The composition of the macroareas is balanced (37, 33 and 40 people respectively for macroareas A, B and C).
41/48 people have indicated a depth range of the activities within 10 m depth, with some other people (37/48) indicating 10-40 m depth. Most of the application have a size area comprised between 1 and 100 sqm, with a required spatial resolution comprised between 1 and 5 cm. Almost 100% of the participants are interested in 3D data, 93% of the sample uses underwater photogrammetry as acquisition technique and 1/3 of the participants acquire data via a scuba diving operator.
You can now access the full report of the questionnaire in the deliverables page.
Possible topics that will be covered during the interviews to meet the project objectives:
Multimedia geometry for underwater image and range measurements
Geometric calibration, colour correction and restoration, validation of systems for underwater 3D measurements
Combined above-water, through-water and underwater techniques for 3D modelling and mapping of coastal habitat
Lidar, photo and spectrally derived bathymetry for seafloor and water surface measurement
Spaceborne techniques and applications for coastal mapping
AI-driven solutions for through-water, underwater and habitat mapping applications
Algorithms and methods for underwater localization, navigation and mapping, including, SLAM, visual inertial odometry, augmented and virtual reality applications
Sensors’ integration and performance evaluation of UAVs, UUVs (ROVs and AUVs), towed vehicles and diver operated systems
Underwater applications and methods in archaeology, habitat mapping and monitoring, industrial metrology and inspections, volumetric reconstruction for flow tracking
