Tuning GDAL Raster Performance
Mr Frank Warmerdam
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.
Frank Warmerdam has been a contract geospatial software developer focused on data access and interchange since 1998. He is the founder of the GDAL/OGR project, and contributing to projects such as MapServer, PROJ.4, OpenEV, libtiff and libgeotiff. He is a founding member and director of the Open Source Geospatial Foundation (OSGeo). He is a graduate of the University of Waterloo, with a honours BMath majoring in Computer Science.
