# Developing and Testing a User-Focused, Web GIS-Based Food Asset Map for an Under-Resourced Community in Northeastern Connecticut

## TL;DR

A user-focused food asset map was developed to help an under-resourced community in Connecticut access healthy food resources more easily.

## Contribution

This study introduces a web-based GIS tool designed to improve food access and digital inclusion in low-income communities.

## Key findings

- Food-secure participants showed higher usability success compared to food-insecure individuals.
- Users with better diets and higher digital literacy were more likely to pass usability tests.
- The map was generally perceived as easy to navigate, especially by food-secure users.

## Abstract

Background/Objectives: Access to healthy and affordable food remains a challenge for under-resourced communities due to uneven food distribution and the need for reliable transportation. This study developed and evaluated an interactive Geographic Information System (GIS)-based food asset map for a low-income community in Windham, Connecticut to improve awareness of food resources and expand opportunities for fresh food access. Methods: Using the human-centered design (HCD) framework and the Asset-Based Community Development (ABCD) model, the map integrates food locations, transportation routes, and assistance eligibility. Internal pilot testing (n = 8) identified usability issues, leading to updates such as mobile compatibility and user guides. Usability testing (n = 74) assessed navigation performance and user feedback through task-based evaluations and surveys. Categorical map usability, sociodemographic, diet, and health characteristics were tested for participants with food security (yes/no) or digital literacy (passed/failed). Results: Food-secure participants showed higher usability success than food-insecure individuals (p < 0.05), while those relying on food assistance faced greater challenges (p < 0.05). Individuals rating their diet as “very good/excellent” were most likely to pass the map usability testing (p < 0.05), whereas younger, college-educated, employed participants and those with vehicles trended toward passing (p < 0.1). Participants generally reported the map easy to navigate, especially those with food security. Conclusions: The asset map promotes food resource awareness and addresses barriers such as limited public transportation information. Additional efforts are needed to support food-insecure users in utilizing digital food access resources. This study contributes to initiatives to improve food access, digital inclusion, and community engagement in under-resourced communities.
