GeoAccess - Plant Health & Invasive Species Mapping

Aerial mapping can quickly and efficiently provide a means to assess the health and condition of a wide range of vegetation types and identify invasive species. The maps are a powerful tool for agronomists, farmers, growers and vegetation management teams to locate areas of concern quickly and allow ground-truthing to determine the problems and remedy the situation in much quicker time and make significant cost-savings.

The Detail

Visible-spectrum images captured by the drone can be used to produce plant health maps using the Visible Atmospheric Resistant Index (VARI). Used in conjunction with a high-resolution ortho-mosaic this enables a snapshot of the health and condition of a wide range of vegetation types to be obtained in relatively short time. Plant health maps can be exported as several file formats, including shapefile (.shp) for use in agricultural software; GeoTIFF for GIS and JPEG for general viewing, for use in:
