摘要：
Fast image generation from vector or raster data for map navigation by Web clients is an important Web application today. Raster data obviously account for the larger Volume of the underlying data sets served through WMS and other such interfaces. Dedicated server implementations prevail because an often heard argument is that general-purpose server software, such as database systems, cannot be efficient enough for such high-volume application scenarios. In this paper we refute that. We investigate just-in-time compilation of query fragments in two variants, for CPU and CPU; as implemented in the general purpose raster FUNIS rasdaman. Results suggest that array databases are suitable for realtime geo raster services.
