Spatial Sampling in the Ocean: A Modest Proposal
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
A new tool for creating sampling hexagons
by Tim Whiteaker, Research Associate, Center for Research in Water Resources, The University of Texas at Austin, twhit@mail.utexas.edu. I recently needed to create a mesh of hexagons covering a study area in the Arctic for a research proposal. These hexagons … Continue reading
Updating ArcGIS.com Hosted Feature Services with Python
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.
Filtering, performing analysis, and building a web map application with ArcGIS Online

Pioneering Real Time GIS with Social Streams
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
