 Development of an Interactive Web Interface for Spatial Data Warehousing Track: Metadata and Data Publishing Author(s): Nathan Eaton Finding a specific file to download is an inherent problem with many online spatial data clearinghouses. This is particularly true for locating files that are part of a tiled data set such as digital orthophoto quarter quads (DOQQs) or local, high-resolution aerial photos. Interactive index maps used in conjunction with dynamic, database driven Web pages can provide a flexible, yet simple solution to this problem. This paper presents the methodology for developing the Indiana Spatial Data Portal (ISDP), an online spatial data distribution system, which utilizes ImageMapper (an ArcGIS extension by Alta-4) and dynamic, data-driven Web pages based on Microsoft SQL Server and Macromedia ColdFusion. The ISDP provides a single, interactive interface for downloading DOQQs, DOQ mosaics, digital raster graphics (24K, 100K, and 250K), and county mosaics from the National Agricultural Imagery Program. Discussion will include functional aspects and limitations of ImageMapper along with database design decisions and ColdFusion coding options. The ISDP is available online at www.indiana.edu/~gisdata.
