Drones are advantageous in their ability to detect small-sized features, as they produce high-resolution imagery at the sub-meter level. This is particularly important in vector-borne studies because water bodies/containers suitable for mosquito breeding are frequently small. The top row shows a comparison of the pixel size produced by a drone in contrast to two commonly used freely available satellite imageries. The middle row demonstrates changes in the landscape composition across a 2-month window, as captured by drones, which otherwise might be overlooked by satellite images. The bottom row shows imageries with common bands that are available in the sensor often used in drones: RBG cameras (left), multispectral cameras that have NIR and red edge band (middle) and an NDVI composite using red and NIR bands (right). MS, Mass spectrometry; NDVI, normalized difference vegetation index; NIR, near infrared; RBG, red, green and blue color model
