With the development of agricultural production data, more and more three-dimensional visualization of monitoring data has become the focus of agricultural information technology research. The application of ArcGIS visualization technology, 3D visualization of auxiliary plug-in, and the national Spark Program demonstration area of farmland monitoring data obtained in Jilin province Nong’an County Helong town of application. In this study, the use of C++ language, the introduction of three-dimensional visualization library SDK, compiled auxiliary plug-in ArcGIS software, optimize the joint jiulongzhen farmland monitoring data 3D visualization. The experimental results show that the preparation of the postprocessing plug-ins integrated into ArcGis software can optimize the 3D visualization of monitoring data, the two-dimensional spatial variability of thematic map than the traditional representation of 3D data more natural, more clear, more intuitive, is of great significance for promoting the development of modern agriculture.
