Web Accessibility emerged as problem when disabled and elder people started interaction with web contents soon after the inception of World Wide Web. When web based GIS applications appeared on the scene of web and users of these kinds of applications increased, these applications faced the similar problem of accessibility. The intensity of web accessibility problems in GIS based applications has increased rapidly during recent years due to extensive interaction of user with maps. Web Accessibility problems faced by users of GIS applications are identified by content evaluation and user interaction. Users are involved in identification of accessibility problems because guidelines and automated tools are not sufficient for that purpose. User Centered Approach is used to include users in the development process and this has also helped in identification of accessibility problems of the users at early stages. The thesis report identify the accessibility issues in Web based GIS application by content evaluation and user interaction evaluation. MapQuest, a web based GIS application, is taken as a case study to identify the web accessibility problems in GIS applications. This thesis report has also studied that how accessibility of the web based GIS applications can be enhanced by using UCD approach in development process of GIS applications.
