Crop diseases and pests monitoring based on remote sensing: a survey

Crop diseases and pests have caused substantial yield losses every year in china, so the monitoring for crop diseases and pests accurately and timely is urgent. Remote sensing technologies offer an efficient and nondestructive way to acquire crop information over relatively large areas quickly. Crop diseases and pets monitoring based on remote sensing is becoming a promising research filed. This paper introduced four kinds of methods for crop diseases and pests information acquisition by remote sensing first. Then five classes of crop diseases and pests information analyzing techniques based on remote sensing are discussed. Finally, this article talked about some remaining problems of remote sensing based crop diseases and pests monitoring and pointed out the future development directions of this filed.
