Since the underlying distribution of snails is partially known, often being focal, developing pragmatic spatial models that interpolate snail information across under-sampled regions is required to understand and assess current and future risk of schistosomiasis.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Methods<\/jats:title>\n                <jats:p>A secondary geospatial analysis of recently collected malacological and environmental survey data was undertaken. Using a Bayesian Poisson latent Gaussian process model, abundance data were fitted for <jats:italic>Bulinus<\/jats:italic> and <jats:italic>Biomphalaria<\/jats:italic>. Interpolating the abundance of snails along the shoreline (given their relative distance along the shoreline) was achieved by smoothing, using extracted environmental rainfall, land surface temperature (LST), evapotranspiration, normalised difference vegetation index (NDVI) and soil type covariate data for all predicted locations. Our adopted model used a combination of two-dimensional (2D) and one dimensional (1D) mapping.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Results<\/jats:title>\n                <jats:p>A significant association between normalised difference vegetation index (NDVI) and abundance of <jats:italic>Bulinus<\/jats:italic> spp. was detected (log risk ratio \u2212\u00a00.83, 95% CrI \u2212\u00a01.57, \u2212\u00a00.09). A qualitatively similar association was found between NDVI and <jats:italic>Biomphalaria<\/jats:italic> sp. but was not statistically significant (log risk ratio \u2212\u00a01.42, 95% CrI \u2212\u00a03.09, 0.10). Analyses of all other environmental data were considered non-significant.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Conclusions<\/jats:title>\n                <jats:p>The spatial range in which interpolation of snail distributions is possible appears &lt; 10km owing to fine-scale biotic and abiotic heterogeneities. The forthcoming challenge is to refine geospatial sampling frameworks with future opportunities to map schistosomiasis within actual or predicted snail distributions.
