MapStudy is an integrated framework for creating survey applications to test cartographic design and interactions in a web map environment. It allows researchers to design map-based surveys with different map libraries, layers, interactions and question types. The framework includes modular components for maps, questions and server functionality. Researchers can use MapStudy to set up customized online surveys and collect data on user interactions to inform map design. Future work will expand its map libraries, interactions and question flexibility to support more complex user studies.
