Weed Mapping (Sugar Cane – Brazil)

This page contains our Orthomosaic Dataset of RGB aerial images for Weed Mapping and Segmentation and its Ground Truth (GT). It depicts a sugar cane plantation in Northern Brazil, captured as a single UAV-acquired sugarcane field orthomosaic. The image was captured from an Horus Aeronaves (https://horusaeronaves.com/) fixed-wing UAV employing a visible light RGB Canon G9X camera.  The UAV captured the data following a flight altitude of 125 to 200 meters, resulting in an approximate  spatial resolution of 5cm/pixel.

The images can be downloaded at full resolution by either accessing the direct links under the illustrative low-resolution images below or by clicking at the images themselves.

Ground Truth

From the dataset an expert biologist produced a human-made ground truth (GT). The expert classified the whole image manually, using the GNU image manipulation program (GIMP). All pixels of the image were classified into three classes: crop row (green), weed (yellow) and background (red).  Out-of-boundaries pixels are black. This GT representation allows the direct usage of the GT in machine learning environments that employ the Pascal VOC standard.
