The iOS/Android application 'e-SoilMap' for creating a new user-oriented soil map

摘要

To enhance the efficiency of soil information in the field survey, we developed the mobile application called "e-SoilMap" for creating a new user-oriented soil map. This application has the following three unique functions: annotatable map, data sharing over the cloud and offline support for allowing the user to create a high-value-added soil map in their Internet space. Both iOS and Android versions of the mobile application mainly consist of three key components: (1) a map manager, (2) a soil manager and (3) a user manager. The map manager is responsible for displaying background maps to the user. The soil manager displays a soil map and related soil information, which are provided by the National Institute for Agro-Environmental Sciences (NIAES), on the background maps. And the user manager is responsible for creating an annotatable map and sharing the user data in the cloud. The "e-SoilMap" provides soil information to users using location-based spatial query processing and allows the creation of annotatable pins on the soil map. The main target of this application was designed to be a wide variety of technical fields such as agronomic assessment, engineering applications, hydrology and hydrogeologic assessments, environmental assessment and policy decisions
