Cost for plant survey has been dramatically reduced due to the development of mobile technology to obtain pictures with their GPS coordination. We developed a PlantGPS system consisting of an Android application specialized for collecting plant pictures and their locations using mobile devices, a server-side component for uploading data, and a web-based interface for managing and analyzing data. As examples of application of our PlantGPS system, surveys of “plants in Nangsae (Daksum) Island” and “ferns in Chollipo arboretum” were conducted. Results showed that our PlantGPS system could be used to quickly survey plant distribution in restricted area with reasonable time and effort.
