Landscape Ecology and Epidemiology of Malaria Associated with Rubber Plantations in Thailand: Integrated Approaches to Malaria Ecotoping

Table 1

The disadvantages and advantages of remotely sensed satellite imagery and UAV imagery.

Criteria	Satellite imagery	UAV imagery
(1) Scalability	Largely perspective landscape scale	Smaller perspective landscape scale; the UAV whose flying altitude is at 300 meters of scales to a coverage area of 1.5 to 2 km^2 per fight for the multirotors or up to 5 km^2 per fight for the fixed wing
(2) Coloring and brightness	Equitable image as often the cloud cover does not permit virtually clear vision	No equitable image but less likely to be deviated by the cloud cover; a series of aerial photos taken by the projective camera requires time-consuming
(3) Precision	Highly accurate and georeferenced image	Based on the calibration of georeferenced image before UAV image processing
(4) Ground resolution	Highly definite but very difficult to adjust the resolution	Easily adjusted to the desired resolution based on flying altitude
(5) Cost	Too costly as the purchase order usually requires time-consuming	Low cost and less time-consuming
(6) Timeliness	Outdated	Timely as desired
