| Abstract: |
| Purpose As the volume of soil survey data increases，the existing analysis and mapping efficiency cannot meet the output demand of results. A set of data analysis and mapping software set is needed to reduce the analysis and mapping threshold of soil survey data，improve the mapping efficiency，and help the effective precipitation of soil survey results.Method This article is based on the software design pattern of B/S architecture and utilizes WebGIS technology for user interaction with mapping features. It employs virtualization technology to isolate the algorithmic environment，stream-based file read/write techniques to handle large data input/output，and webGL rendering and shading techniques for mapping visualization. From the perspective of both algorithmic development and application，logical relationships and interaction modes between components of the soil mapping tool are designed.Result A soil survey mapping software was designed and implemented，which integrated several algorithm functions including IDW inverse distance weighted interpolation algorithm，Kriging interpolation algorithm，and random forest algorithm. In addition，functional modules for soil quality evaluation，soil fertility evaluation，and soil suitability evaluation were developed. The software also achieved the atomization of operational steps，standardization of calculation processes，and configurability of calculation parameters.Conclusion On the premise of ensuring accuracy，it effectively reduces the difficulty of soil mapping and improves the efficiency of soil mapping. |
