Practical Aspects of Ikonos Imagery for Mapping

Availability of high-resolution imagery, such as IKONOS (from Space Imaging Corp), has opened new possibilities for satellite-based mapping. This paper aims to share the practical experience of authors in using IKONOS imagery for mapping application in a production environment. Authors are involved in an IKONOS based land-cover mapping project jointly undertaken by Intergraph Philippines Corporation and the National Mapping and Resource Information Authority (NAMRIA), of the Philippines . As IKONOS imagery applications are still in its immerging phase, it is felt that the experiences shared herewith will benefit those considering the use of IKONOS imagery as one of the data sources for mapping applications. This paper aims to present some of the features that differentiate IKONOS imagery for mapping applications from other commercially available satellite imagery.
