Abstract: | Spatial profiling of community food security data can help the targeting of geographic areas and populations most vulnerable
to food insecurity. While multiple poverty mapping systems support spatial profiling, they often lack capabilities to disseminate
mapping results to a wide range of audiences and to spatially link qualitative data to quantitative analysis. To address these
limitations, this study presents a web mapping framework which integrates a variety of publicly available software tools to
enable spatial exploration of both quantitative and qualitative data. Specifically, our framework allows online choropleth
mapping and thematic data exploration through a mixture of free mapping Application Programming Interfaces (APIs) and open
source software tools for spatial data processing and desktop-like user interfaces. The study demonstrates this framework
by developing a web prototype for informing food insecurity issues in Bogotá, Colombia. The prototype implementation reveals
that the proposed framework facilitates the development of scalable and functionally-extensible mapping systems and the identification
of community-specific food insecurity problems (e.g., food kitchens inaccessible from workplaces of low-income residents).
This suggests that web-based cartographic visualization using publicly available software tools can be useful for spatial
examination of community food insecurity as well as for cost-effective distribution of the resulting map information. |
