ANALYSIS OF VEGETATION AND THE ENVIRONMENT USING DRONES
Vegetation and environmental properties can be determined and analysed with the help of satellite images or aerial photographs from planes. However, aerial surveys with aircraft are very expensive due to staff and fuel costs. Satellite data only have a low spatial and temporal resolution. Furthermore, the images are linked to the satellite’s orbit. Satellite images are therefore, often unsuitable for tasks in the area of environmental analysis and vegetation analysis.
The development of smaller and lighter hyper- and multispectral sensors has opened up new opportunities for recording and assessing vegetation and environmental properties over the visible spectrum with drones. Applications in the areas of precision farming, renaturation, detection of stress factors, assessment of the conditions of water bodies, etc. can thus be realised quickly in a cost-effective manner. In addition, the land cover and land utilisation can be classified in a reliable manner using the high spectral information density.
In addition to the corresponding georeferenced land cover maps, time series analyses, for example as part of a change detection, can also be performed. The experts at SPECTAIR can also produce additional 3D terrain models and elevation models on request.
