The updating of small and medium scale vector terrain database in china has been carried out regularly for many years. But in difficult areas such as depopulated zone, the surveying and mapping work is limited to the impact of many objective factors such as traffic, climate and environment. In particular, the research on the production technology of geomorphic data relying on photogrammetric technology is of great significance. In order to improve the efficiency and applicability of basic surveying and mapping, the technology of geomorphic elements production based on existing geographic information data was discussed and studied, and the manufacturing flow was designed. For different data source conditions, several test areas were selected for production, accuracy verification and results analysis. Forming a complete production solution which can provide implementation suggestions for geomorphic data production under similar conditions.
