The main purpose of this study was to identify the topics and research trends of international cadastral research using LDA. To achieve this goal, I reviewed the literature on LDA and international cadastral study and formulated four research questions that are topics of cadastral researchers, distribution of topics, the most influential topics and changes of topics over time. To answer these research questions, I analyzed 370 papers published in the FIG Peer Review Journal between January 1, 2008, and October 31, 2017, using LDA. As a result of the analysis, I confirmed that there are twelve major topics in international cadastral research. And the most influential topic of these topics was identified as topic 2(cadastral information systems), and topic 5(land development and land administration) was also confirmed as playing an important role in the overall document. These two topics have been the most popular topics whose trendlines have been very active over the past decade and will play a leading role in future cadastral research. KCI Citation Count: 3
