# The Construction of a Digital Agricultural GIS Application Suite
## 3 Result and Discussion
### Component Design Considerations
These results are presented as time-series data, with a statistical analysis showcasing the frequency and severity of pest and disease occurrences. Cultivation suitability evaluation component: This component has the function of analyzing and displaying the planting suitability of different crop types and different natural conditions. The crop types to be evaluated for suitability, such as rice, corn, potatoes, etc., are selected according to evaluation indicators including topography, water, light, etc., and planting suitability results are determined according to the set growth condition threshold. Finally, planting suitability layers are displayed on the map. Agricultural object space component: Using the multi-granularity spatial-temporal object management method for reference, the agricultural object space is established step by step according to the tree structure of the agricultural object. This component has the function of displaying the spatial tree structure of agricultural objects and displaying the information of agricultural multi-granularity spatial-temporal objects. The objects are classified into layers in the form of a tree map, and the classification method is China-provincial level-city level-district-county-township-land. Each level of object information is displayed from the eight aspects of time and space reference, spatial position, spatial form, composition structure, correlation relationship, cognitive ability, behavioral ability, and attribute characteristics. \begin{table}

Table 1: Cont. Agricultural thematic map component: With an agricultural thematic information map display function, this component classifies agricultural thematic maps, provides selection boxes for map settings and indicator settings, and then visually displays custom thematic layers. The interface design of each component follows the principle of consistency, abstracts the business logic of each component, focuses on the information capacity of the component and the relationship between the combination and layout of the component, and designs a well-consistent component interface based on the map and operation logic. On this basis, the above components are realized based on the low-code development platform magic-editor and microservice technology, and if we take the agricultural thematic map component and cultivation suitability evaluation component as examples, their effects are shown in Figures 5 and 6.
