Aggregated Live Feeds in ArcGIS


Live data bliver mere og mere en forventning fra brugerne af GIS systemer. Det giver ikke mening for mange at skulle kikke på år gamle data. Services til at se f.eks toge eller busser på et kort har ikke særlig stor interesse hvis det kun viser hvor køretøjet var kl. 13.08 d. 7. juni 2003 ...

We have developed a methodology on how to aggregate Internet accessible data (eg. USGS/NOAA xml, GeoRSS, and so on) as services through ArcGIS Server. We load the aggregated data into layers within ArcSDE, expose them as Spatial Views, and serve through ArcGIS server in near real time. Any client that can consume ArcGIS Server services can leverage these services (ArcGIS Desktop, ArcGIS Server, ArcGIS Explorer, etc). This technique was developed in response to the desire to show near real-time data (such as weather data) and analysis within all of our ESRI products. [...]
