MULTISPECTRAL

Multispectral imaging captures and records light across a range of wavelengths within the electromagnetic spectrum, including those outside of the visible spectrum, such as infrared and ultra-violet. As a result, multispectral imaging provides the ability to extract additional information which the human eye or standard industrial vision cameras fail to capture.

And this extra information has tremendous value to those in agriculture, forestry,  land management and archaeology.

Agriculture 

Multispectral cameras detect subtle changes in plants, such as those in the red edge band, to identify stress from disease, pests, drought, or nutrient deficiencies before they are visible to the naked eye. This is useful for not arable or pastoral farming, particularly in the upland hills and mountains of Wales, where sustainable farming meets pressures from habitat degradation and declining biodiversity. 

Forestry

By having access to multispectral data and obtaining vegetation index data such as NDRE and NDVI, foresters can assess forest and woodland health, monitor deforestation a track tree and canopy growth. This is particularly useful in early identification of disease and pest infestation to allow for timely action to protect valuable forest resources.

Land Management

Multispectral data can assist in the planning and management of land utility, from topographical assessment of new sites to managing and monitoring of use or disused sites. In North Wales, data from multispectral cameras can be used to track water egress and plant coverage in spoil tips to provide risk surveys for old mining spoils and tips. 

Archaeology

UAVs use multispectral cameras to provide non destructive or invasive ways to survey and identify archaeological features not visible to the naked eye. Archaeological features, such as buried walls and earthworks can be picked out using multispectral data, allowing for accurate and timely survey data.
