Information and communication technologies (ICTs) are playing an increasingly vital role in the daily lives of people, revolutionising work and leisure and changing the rules of doing business. In the realm of government, ICT applications or e-government are promising to enhance the delivery of public goods and services to citizens not only by improving the process and management of government, but also by redefining the traditional concepts of citizenship. e-government is the use of information and communication technology, combined with organisational change and new skills to improve public services. There are two main types of web-based applications for spatial data-based e-government applications over the internet: (a) interactive web-based maps that can be queried on the internet and (b) spatial databased e-government information that can be accessed by the clients or public on the internet. In Turkey, although there is a remarkable improvement in the non-spatial data-based e-government applications, there has been little progress in spatial data-based e-government applications. This paper discusses spatial data-based e-government applications developed so far to allow the user to access e-government spatial information through the internet. The paper presents results of a pilot application of the system design developed to carry out emunicipality applications.
