Abstract:Spatial Information remains key to any societal development and its importance is greater seen in most decisions in our society. Current trends have this information easily accessible via the internet, through different services and products. These services, though of great importance are not easily accessible to people in the southern contexts where the Internet is out of reach for many. Fortunately, the mobile phone in its basic form has an almost ubiquitous presence in these societies. Stemming from this presence, the mobile phone can then serve as an efficient communication platform. In this research project we explore the means of providing crucial spatial information to people in the southern contexts in two-way SMS services involving an SDI node. To propose the architectural framework, we review and scan current or ongoing projects defining and deriving the possible SMS and SDI functionality. The functionality derived is used to create a messaging scenario of a messaging service for rain information. This scenario is used to create a test use case for the SMS-SDI node messaging. The use case, using the systems approach in a service oriented environment, is used in the architecture formulation for the two-way SMS system involving an SDI node. The proposing the architectural framework we also highlight the limitations of the SMS technology and those of the SDI technology and how integration can be made possible. The proposed architecture is implemented for the use case and reviewed. The review leads to a general framework architecture that provides the means in which SMSs can be used in conjunction with SDI nodes to communicate spatial information in a two way manner. Keywords Short Message Service, SDI node, two-way architecture, SDI-SMS architecture, Spatial Data Infrastructure
