At the Esri Oceans Summit there were several “hallway conversations” about a lack of spatial sampling tools in ArcGIS and how this had led people to use Hawth’s Tools (now Geospatial Modelling Environment) and other approaches in order to perform … Continue reading

More organizations are moving towards using ArcGIS.com hosted feature services to serve data. One common task that has become a popular question of late is, “How do I automatically update the data within this hosted service?” For example, your organization may want to push nightly updates to keep synchronized with the daily changes made by your Desktop users. One of the easiest ways this can be done as this blog describes, is by overwriting the feature service completely with an updated one.
The following Python script demonstrates how to:
- Turn a map document into a sddraft.
- Modify the XML inside with the appropriate settings.
- Analyze the draft for errors.
- Stage the sddraft into a .sd (service definition) file.
- Upload the service to ArcGIS.com. Note that this code shares the feature service with everyone on ArcGIS.com.
With ArcGIS Online, individuals, governments, and organizations alike can create and share compelling map stories. For example, by using just two map layers, law enforcement officials could use ArcGIS Online to determine the locations where crimes are occurring, perform spatial … Continue reading

Jump-start your conference a day early by joining us for the 20th annual pre-conference Water Resources Workshop on Sunday July 7th. The Water Resources Workshop is a FREE, full day workshop focused on emerging trends in the integration of GIS and Water Resources and how you can use them in your work.
The proliferation of mobile, social and sensor data has given us a new playground for analysis and visualization. It is an area we’ve beenparticularlyexcited about from our earliest experiments with streaming data. Since joining ESRI we’ve had the opportunity to focus on these emerging data sources, and integrate them into the larger concept of Real Time GIS. Baking our ideas into this broader framework gave us the opportunity to fully move past Tweets on a map. Continue reading
By Damien Demaj Late last year I introduced ArcGIS users to sports analytics, an emerging and exciting field within the GIS industry. Using ArcGIS for sports analytics can be read here. Recently I expanded the work by using a number … Continue reading
