Generating a caption for an aerial image describing its content in comprehensive way is less studied but important task as it has applications agriculture, defence, disaster management and many more areas. Though different approaches were followed natural generation, generating remains challenging due to special nature. Use of emerging techniques Artificial Intelligence (AI) Natural Language Processing (NLP) domains resulted generation accepted quality captions images. However lot needs be done fully utilize potential task. This paper presents detail survey the various by researchers The datasets available experimentation, criteria used performance evaluation future directions are also discussed.
