Spatial Information System in the Context of Developing Spatial Data Infrastructure

Abstract

This study focuses on the spatial information system in the context of developing spatial data infrastructure, developing spatial data infrastructure in the context of this study is  a spatial data infrastructure whose operational capacity does not satisfy the standards befitting of a functional or operational spatial data infrastructure. The researcher assumes spatial information system as the sum of the spatial data and spatial information obtained from a geographic information system manipulation, synthesized to give spatial information system useful for information exchange and sharing in spatial data infrastructure. Qualitative review of relevant texts and web information were used for the subjective analysis of the information obtained. The result obtained revealed a glaring gap difference in the understanding, performance and readiness of spatial information among the three geospatial communities analyzed, indicative of the context in which spatial information is held for spatial data infrastructure performance. An attempt was made to proffer requirements necessary for spatial data infrastructure.
