Oil palm is a major economic crop and the area of land converted to oil palm cultivation in the tropics has expanded rapidly. Oil palm has become the world's largest source of vegetable oil and it provides tremendous regional economic benefits. However, the expansion of oil palm cultivation has led to the loss of forests, arable land, and peatland, which has caused severe ecological and environmental problems. Application of 3S (RS, GIS, GNSS) technology is useful for the collection, analysis, and management of spatial information, and is essential for both optimizations of the spatial distribution of land use and sustainable development. This paper analyzes the progress of 3S technology application in oil palm research on the basis of a literature review and scientometric analysis. The factors affecting the precision of oil palm mapping are also discussed. We established that papers describing 3S technology application in oil palm research are based primarily on the study of land cover change, and that scientific institutions and researchers in Malaysia, the United States, China, Indonesia, and the United Kingdom are the major contributors. Currently, the application of 3S technology in oil palm research includes oil palm mapping, oil palm land change monitoring, oil palm tree counting, tree age estimation, aboveground biomass and carbon storage estimation, suitability analysis, yield estimation, pest and disease monitoring, and plantation management. The accuracy of mapping is not correlated significantly with the year of publication of specific literature but is correlated with RS data sources and classification methods. The use of 3S technology in oil palm research is currently dominated by RS, which has been used in diverse fields of oil palm research. GIS technology is used mainly for oil palm land change mapping, suitability analysis, plantation management, and pest and disease monitoring, while GNSS is used largely as an additional tool in pest and disease monitoring and plantation management.
