 This dataset contains a series of multispectral image slices captured at the embankment dams and dikes 
 of the Belo Monte Hydroelectric Complex, located in the state of Pará, northern Brazil. Each image is 
 paired with its respective NDRE vegetation index values, binary segmentation mask and multiclass 
-segmentation mask
+segmentation mask.
+
+The multispectral images were captured by the Micasense RedEdge-P multispectral sensor embedded in a 
+DJI M210 V2 UAV. Radiometric calibration was performed for all images based on the known reflectance
+values of a calibration panel. All images were used to process a Digital Ortophoto Map, which was then 
+sliced into the 256x256x5 image patches that are contained in this dataset.
+
+Each image file is composed of six channels:
+
+1. Red band reflectance
+2. Green band reflectance
+3. Blue band reflectance
+4. Red Edge band reflectance
+5. Near-infrared band reflectance
+6. Binary cutline
+
+The vegetation index (NDRE) values were calculated based on the spectral bands and the segmentation masks
+were manually annotated using the CVAT software.
