The world today has evolved into an information society. Information is key to the operation of government and all sectors of the economy. Good information is needed to formulate informed decisions. The information needs to be accurate and accessed at the required time. Online access of basic information by citizens through the creation of one stops is the concept that most governments are advocating for. This is known as e-government which is the subject of discussion of this study. This study concentrates on spatial data and Public Sector information. Enhanced access to spatial data and other public sector information has a bearing on good governance, sustainable development and eventually the adoption of open government by nations. A comprehensive study is done in major government departments to determine what public sector information, access mechanisms, interagency exchange and availability of information to the public. Available electronic services are assessed as part of e-government evaluation using a set of indicators. Spatial data access is reviewed from different stakeholders including public sector, local government, Non-governmental organisations and private sector agencies. Factors motivating and impeding organisations to share spatial data and PSI are also analysed. The benefits of sharing key information across government are discussed. This study evaluates spatial data access and key public sector information. E-government is assessed to analyse access of key government services by the public. This readiness is in the end, the key to open government. This study borrows concepts from the fields of Public Administration, E-government, Economics and Spatial Data Infrastructures. The world is building towards knowledge economies in which openness in terms in information, knowledge and governance is crucial. Public participation should be encouraged in planning and governance issues and in the creation of community based spatial data sets.
