Abstract:Testing multivariate geovisualizations, for example glyph designs, for their perceptual qualities requires suitable test data. Synthetic data can be useful for evaluating different data characteristics and their perceptibility through different designs. Real data may not contain all relevant data characteristics, for example with regard to spatial distributions or trends, which may be interesting for testing. Additionally, real data may contain a lot of noise or randomness. Even though, real data are imperativ… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
