Web mapping performance is often constrained by the speed of access to the underlying geospatial data. A comparison of different file formats, image organization techniques, compression, caching and other factors will be discussed in the context of their impact on performance for raster data access intensive applications. Results will be presented for the particular case of web mapping with MapServer on top of the GDAL raster data access library.
