OpenStreetMap (OSM) is a recent emerging area in computational science. There are several unexplored issues in the quality assessment of OSM. Firstly, researchers are using various established assessment methods by comparing OSM with authoritative dataset. However, these methods are unsuitable to assess OSM data quality in the case of the non-availability of authoritative data. In such a scenario, the intrinsic quality indicators can be used to assess the quality. Secondly, a framework for data assessment specific to different geographic information system (GIS) domains is not available. In this light, the current study presents an extension of the Quantum GIS (QGIS) processing toolbox by using existing functionalities and writing new scripts to handle spatial data. This would enable researchers to assess the completeness of spatial data using intrinsic indicators. The study also proposed a heuristic approach to test the road navigability of OSM data. The developed models are applied on Punjab (India) OSM data. The results suggest that the OSM project in Punjab (India) is progressing at a slow peace, and contributors’ motivation is required to enhance the fitness of data. It is concluded that the scripts developed to provide an intuitive method to assess the OSM data based on quality indicators can be easily utilized for evaluating the fitness-of-use of the data of any region.

E-commerce websites are doing extremely well despite the global slowdown in the traditional brick-and-mortar retail industry. Web page design, search options, and graphical layout may greatly influence the customer base of any e-commerce website. This paper intends to identify the most influential elements of a graphical interface and their effect on consumers’ visual attention. Visual layouts having major influence on customers’ decisions during online shopping were investigated using eye-gaze tracking. Data from 76 respondents were collected to identify parts of the graphical interface attaining maximum user attention in terms of first fixation of eye-gaze and fixation count. Heat maps were used to visualize the results. The results revealed a clear impact of graphical interface on gaining user attention. Further, the experiment also revealed gender-specific visual preferences toward various parts of graphical user interface. The results may further be extended to evaluate product design, packaging design, promotional design, and graphical interfaces of websites.
