A more efficient way of integrating Watershed Boundary Dataset (WBD) into web-based Agricultural Integrated Management System (AIMS)
Proceedings of the 2022 Mississippi Water Resources Conference

Year: 2022 Authors: Sahin A.N., Ozeren Y.

Agricultural Integrated Management System (AIMS) is a web-based tool developed by The National Center for Computational Hydroscience and Engineering (NCCHE) University of Mississippi, and USDA-ARS National Sedimentation Laboratory, for watershed conservation management planning. AIMS is intended to provide a user-friendly environment for data analysis and watershed modeling with automated input data preparation capabilities from seamless geospatial data for any watershed in the United States. Watershed Boundary Dataset (WBD) is used to define the simulation boundaries of AIMS models including the topographic landscape analysis tool TopAGNPS. One of the advancements of the new AIMS environment is GeoJSON data format to represent geospatial features, which required conversion of WBD hydrologic unit boundaries into GeoJSON data format, and re-establishment of the hydrologic unit hierarchy. The conversion enables inter-operation between backend Python and Java modules, and the watershed simulation models running under AIMS, including TopAGNPS, for locally transferring remote or saved structured data independently from the map servers. This allows importing the geospatial data as an object with its hierarchy for backend operations without requiring additional parsing or server-side operations (authentication, data transfer, etc.). This method also increases the stability, security, and speed of the system and decreases its dependency of it on external resources. The key features of the new AIMS platform including the updated WBD will be presented.
