TerraImaging, Germany/The Netherlands, successfully finalised high precision airborne data capture of the Maltese archipelago, from ocean floor to church spires, and work is well underway to complete one of the first fully integrated Topograhic Lidar, Bathymetric Lidar and SWATHE bathymetry datasets of a nation’s Economic Exclusion Zone around the island up to one nautical mile and 200m depth. This is part of a project to develop a national environmental monitoring infrastructure and capacity.
The project, carried out by TerraImaging and its partners, will contribute to a baseline survey of the Maltese Islands and is to complement multibeam dataand topographical Lidar and oblique imagery to produce an integrated 3D perspective of the Maltese Islands.
All flight operations ran successfully, only disrupted occasionally by the strong winds and low clouds and some bad weather periods.
The project combines 3D data and high resolution spatial data, acquired with the latest generation of equipment. The terrain of the islands has been scanned with a Riegl 680i lidar system (point density better than 4 Pt./m², accuracy better than 10cm). Another first-timer for Malta was the acquisition of oblique images acquired during the aerial survey with an A3 digital camera (oblique and Nadir imagery, resolution 15cm). Unlike traditional aerial photography which only gives an overhead view, oblique images are aerial photographs that are taken at an angle. This means that a feature, such as a house or a building, can be seen from the front, back and sides. This is a recent technology which dynamically changes the use of visual information systems. Digital aerial images were also acquired with the aim to update MEPA's current digital aerial maps. The summer months just saw another 3D scan being taken, this time measuring sea depths up to 200m within 1 nautical mile from the coastline.
The project is co-financed by the European Regional Development Fund for the Maltese Environment and Planning Authority , which provides 85% of the project’s funding and the Government of Malta, which finances the rest under Operational Programme 1 - Cohesion Policy 2007-2013 - Investing in Competitiveness for a Better Quality of Life.
The ocean floor around the islands has been scanned with a Hawkeye IIB bathymetric laser system (depth from 0 to 15m, grid of 2 x 2m). A SWATHE bathymetry system took care of deeper areas up to 200m. This resultant 3D bathymetric scan and the 3D terrain scan will then be merged to form an integrated 3D perspective for the Maltese Islands. The data will help MEPA to manage and plan the highly populated island in a more efficient way.
In the meantime, data on air, water, radiation and soil will also be acquired within the project, which will be completed in June 2013. Dr. Elaine Sciberras, Project Leader for this ERDF project, noted that "the project will enable Malta to obtain valuable environmental information both for EU reporting obligations as well as to improve environmental policies and planning. The innovative aerial data acquired is crucial to providing a 3D spatial element to the environmental data being acquired. This will enable enhanced environmental analysis and planning." The ERDF project also involves enhancement of the national monitoring programmes on air, water, radiation, soil and noise, the procurement of equipment, and training of staff.
All data from the project will be viewable from a web portal. This portal, known as a Shared Environmental Information System (SEIS), will be launched towards the end of the project.
In the coming months, TerraImaging will be processing the data acquired from the aerial surveys and will work on the integration of all different datasources.
