Abstract: The Institute for Creative Technologies (ICT) has pursued the creation of One World Terrain (OWT), which aims to provide a set of 3D global terrain capabilities and services that can replicate the coverage and complexities of the operational environment. Research was conducted in support of One World Terrain through development of best practices for the delivery of a raster mosaic via cloud hosting service, created using OptimizeRasters Geoprocoessing Toolbox and the Mosaic Dataset Configuration Script. Though ultimately successful in developing the raster mosaic and hosting it online; JPEG compression lossiness was a key issue with the larger Rose Bowl dataset. Additionally, hosting the imagery via ArcGIS Online was found to increase the compressed file size; making it comparable to the original file size of the data. Future testing should consider usage of an enterprise server to avoid this issue. MRF LERC compression was identified as the ideal file configuration; and ArcGIS Online was identified as a poor enterprise hosting medium. We have also identified a variety of ways to improve the MDCS script in order to automate the whole process more efficiently.
