The objective of this survey paper is to summarize and synthesize the published articles, focused on the fusion of optical SAR and synthetic aperture radar remote sensing data into a systematic literature review, SLR based on the pre -published on the indexed database linked to this subject. subject and describing the latest developments. Systematic literature review atau sering disingkat SLR atau dalam bahasa indonesia disebut tinjauan pustaka sistematis adalah metode literature review yang mengidentifikasi, menilai, dan menginterpretasi, The best proposals arrive in a timely manner and clearly explain why readers should pay attention to the proposed topic .

This paper conducts a systematic literature review, SLR, on automation of SLR studies to collect and summarize the current state of the art necessary to define a framework for further research activities. lists the steps in the systematic review process, as proposed by 4. Synonyms used in the literature have been noted. Research progress, in terms of published literature, on unmanned aerial vehicles (UAVs) has observed exponential growth, as shown in the graph below. The graph represents the published literature indexed by the Web of Science for the keyword "UAV" over the years, and it shows that more articles on drones have been published. Systematic literature reviews, SLRs, have become a standard tool in many areas of management research, but are often presented in a much less rigorous manner than other research. the main differences between related studies are presented. The literature appears to contain few systematic analyzes on the application of Deep Learning in crop yield prediction. There are not many reviews analyzing and evaluating current work on this topic in an objective manner. Guidelines for writing a systematic review. 1. Introduction. A key characteristic of any academic activity is having a sufficient understanding of the area being studied and therefore knowledge of previous research. Undertaking a literature review with an analysis of the results on a specific question is necessary to demonstrate its sufficiency.
