(Combined with the advantages of 3S technology in location acquisition and management, on the one hand, location-based on-site spatial data acquisition is not limited by time and space, which realizes real-time data acquisition, storage and query, and the whole data collection process is integrated; On the other hand, mobile GIS completely adopts electronic operation, which reduces the influence of many factors such as scanning digital resolution and vectorization accuracy, and improves the quality and availability of GIS spatial data. Thus, the accuracy and efficiency of soil data collection are improved.)
