GIS applications, whether they are hosted on a desktop or an Internet server, can pull data content from the Internet using links, feeds and services. GeoRSS is a standard for feeds in which the URL points to an XML file with geospatial tags. For example, by reading a feed that contains point coordinates, a GIS application can track moving objects. Services come in many formats that can be "mashed-up" in GIS applications. Beyond map and image services, GIS applications can take advantage of services specifically designed to query features, locate addresses, create travel routes, run geospatial models (geoprocessing), and more. This presentation will draw examples from the City and County of Honolulu's HONUA system for emergency management which uses a combination of links, feeds and services to provide a common operating picture that updates in real-time.
