Normalized Difference Vegetation Index (NDVI) Imaging
NDVI compares Near Infrared and Red light. It is great for measuring healthy, green vegetation over a wide range of conditions. We have equipped our drones with a multispectral IR sensor to efficiently capture this data in combination with normal RGB bands.
NDVI is a an index that describes the difference between visible and near-infrared reflectance of vegetation cover and can be used to estimate the density of green on an area of land.
UAV Ontario provides aerial survey for farms, provincial/municipal conservation areas and land trusts to gather information pertaining to plant population, disease, flowering, pest detection, plant height and condition.
Case Study - Luther Marsh
Grand Valley, Ontario
UAV Ontario was selected to provide RGB, NIR and NDVI vegetation models for Luther Marsh to the Grand River Conservation Authority. We surveyed the property and marked several horizontal control points for our aerial map several hundred acres.
The resulting outputs were delivered as both raw data and orthomosaic photos for their environmental science team to disseminate the areas and abundance of invasive phragmites throughout the marsh, particularly in areas that were not easily accessible by land or water.
