| Abstract: | The breakthrough developments in geospatial technologies and the increasing availability of spatial data make geoinformation a business and a decisional element to the management. Hence, it is important to have a management plan to factor in practical and feasible data sources, in building geo applications. The authors of this paper are motivated by the fact that right data sources could outclass in-house resources in various application scenarios. This paper outlines pragmatic cases for the tangible benefits of the existing potential data and expeditious patterns for digital earth. This work also proposes ‘good-enough’ solutions based on the pragmatic cases, available literature, and the 3D city model developed that could be sufficient in contriving the objectives of the common public usage and open business models. To demonstrate this approach, the paper encapsulated the low-cost development of virtual 3D city model using publicly available cadastral data and web services. |
