About This Course
Unmanned Airborne Vehicles (UAVs) equipped with consumer-grade imaging/ranging and direct geo-referencing systems have been proven as a potential Remote Sensing platform that could satisfy the needs of a wide range of civilian applications. The continuous developments in direct georeferencing and Remote Sensing (i.e., passive and active imaging sensors in the visible and infrared range – RGB cameras and LiDAR) is providing the professional geospatial community with ever-growing opportunities to provide accurate 3D information used in environmental research to collect information about the Earth, such as vegetation and tree species.
This 4-day course aims to provide participants with an integrated
end-to-end perspective going from measurement techniques to end-
user applications, covering issues related to LiDAR sensors coupled on aircraft and UAVs, computing exercises on the processing of 3D point clouds to produce geospatial products.
Any researchers (PhD and MSc students, post-docs, primary investigators) and environmental professionals who are specialised in a variety of Earth Science disciplines and wish to expand and improve their knowledge and skills.
Availability – 30 places
Duration – 4 days
Contact hours – Approx. 24 hours
ECT’s – Equal to 2 ECT’s
Language – English
The course will be divided into theoretical lectures to introduce and explain key concepts and theories, and practices with computing exercises on the processing of LiDAR data and point clouds. Afternoon practicals will be based on the topics covered in the morning lectures.
Assumed quantitative knowledge
Familiarity with Geographic Information Systems and geospatial data (i.e., raster and vector data) could be useful, but not mandatory. A basic understanding of physics radiation and proprieties of electromagnetic spectrum could be also useful, but not required.
Assumed computer background
No prior experience with LiDAR processing software, point cloud data or any programming language is required.
Equipment and software requirements
Attendees of the course must use a computer with any Operating System installed (GNU/Linux, MS Windows or MacOS). The course will use Open-Source software (FOSS) and some proprietary software which will be downloaded, installed and configured during the lectures.
PLEASE READ – CANCELLATION POLICY
Cancellations are accepted up to 28 days before the course start date subject to a 25% cancellation fee. Cancellations later than this may be considered, contact email@example.com. Failure to attend will result in the full cost of the course being charged. In the unfortunate event that a course is cancelled due to unforeseen circumstances a full refund of the course fees will be credited.
