Spatial filters

Spatial filters are a way for SoilHive users to narrow down the information they are querying and make that more relevant for their research.

Types of spatial filters

Agroecological zones

Based on the The Agro-Ecological Zones (AEZ) modeling framework, developed by the FAO and IIASA, uses land evaluationt principles and various climatic variables to assess natural resources and identify suitable agricultural land use options

Land Cover

Based on the Copernicus Global Land Service (CGLS) provides a series of biogeophysical products (i.e. Leaf Area Index, Land Surface Temperature, soil moisture, etc.) on the status and evolution of land surface at global scale.

Soil Groups

This filter refers to the categories defined by The World Reference Base for Soil Resources (WRB), an international soil classification system developed by the International Union of Soil Sciences (IUSS). These groups classify soils based on their physical and chemical properties, providing a standardized framework for naming soils and creating legends for soil maps. The fourth edition, released in 2022, is the most current version and is used globally to ensure consistency in soil classification and mapping.

Endpoints

• GET /v1/spatial-filters: retrieves all available spatial filters.
• POST /v1/spatial-filters/queries: allows querying specific spatial filters based on an area of interest.

One filter for each spatial filter type can be used and the query will return the intersection of those 3 filters within the area of interest.
