Usability and user experience as key drivers for evaluating GIS application quality

Due to the increasing usage of GIS applications, evaluating their quality takes on high importance and requires a flexible modelling framework that to incorporate the special characteristics of GIS applications in spatial and temporal dimensions. Transforming GIS data into information and then presenting in a meaningful way is a significant challenge, and ultimately affects the user experience. In this paper, we apply a modelling framework to evaluate the external quality for a GIS application. In our evaluation, we focus on learnability with an aim toward improving the user experience. The modelling framework, 2Q2U (internal/external Quality, Quality in use, actual Usability and User experience), is designed to flexibly evaluate software applications for usability and user experience by flexibly combining and relating the concepts of actual usability and actual UX.
