Land
With the demands on land constantly increasing, it’s more important than ever to study land use, land erosion, and soil properties, and to map variations in biology and vegetation. To find out more about investigating mineral deposits, check out Geological Sciences, Minerals, and Mining. Land researchers can use analytical instruments to calibrate and validate airborne satellite images and carry out ground- and lab-based experiments.
