Elevating the RRE framework for Geospatial Analysis with Visual Programming Platforms: An Exploration with Geospatial Analytics Extension for KNIME

Lingbo Liu , Fahui Wang*，Xiaokang Fu, Tobias Koetter ，Kevin Sturm, Weihe Wendy Guan, Shuming Bao

A specific use case was introduced to demonstrate the practical application of the Geospatial Analytics Extension for KNIME, aiming to validate its efficacy through textbook replication and a focused study on spatial accessibility.

Anchored in the RRE framework, we present a case study detailing spatial accessibility to hospitals within East Baton Rouge Parish (Baton Rouge). The study evaluates access for residents across varying census block groups to five acute hospitals. Data pinpointing the location and bed capacity of these hospitals is sourced from the Louisiana Hospital Association's 2021 directory. Supplementary data concerning census block groups, including population demographics and road networks in EBRP, is informed by the 2020 Census.
