Updating your hosted feature service for 10.2

In April 2013, we explained how you could use a Python script to automate the publishing and overwriting of your feature service on ArcGIS.com. This post explains how to perform that same workflow using ArcGIS 10.2 or 10.2.1. The following instructions will get you started, or, scroll to the bottom of this post for extra information on what’s changed at 10.2. Continue reading

Updating ArcGIS.com Hosted Feature Services with Python

Note: A this workflow has been updated for ArcGIS 10.2/10.2.1. Please read that post depending on your version. [January 24, 2014]

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:

Telling thematic stories in ArcGIS Online

By Kenneth Field (Research Cartographer), Damien Demaj (ArcGIS Online Cartography) and Linda Beale (Geoprocessing)

Telling thematic stories in ArcGIS OnlineAt the 2012 Esri Education GIS Conference and the 2012 Esri International User Conference, we demonstrated how you can build informative thematic maps using the ArcGIS System.  The purpose of the sessions was to take relatively simple datasets and create a range of alternative thematic map types that told a story in different ways.  This demonstrated the techniques for creating the maps using ArcGIS for Desktop as our authoring environment and ArcGIS Online as our publishing mechanism.  As the XXX Olympiad is currently taking place in London, UK we illustrated how alternative maps can be made to tell different stories of the relative success of nations over the period since the first Olympic games in 1896.

Developer Summit Europe

To build on the success of recent Developer Summit in California, we’ve decided to take the event on the road. Esri will be hosting 3 Dev Summits in Europe this September.

I hope developers from all over Europe and the world will come together in Rotterdam, Berlin or London (all 3 if you want). The technical sessions will focus on becoming more effective at building web, mobile and desktop applications. Senior Esri development staff will be presenting so you’ll get a chance to see what’s coming next. Registration information will be available soon but mark your calendar now and plan to join us in Europe.

Using a binning technique for point-based multiscale web maps

By Kenneth Field, Esri Research Cartographer

Presenting point-based data on a web map is challenging because of the problem of overlapping symbology, particularly as you zoom out of the map to view data at smaller scales. So-called push-pin web maps are very easy to make with ArcGIS Online but making the map make visual sense at the smaller scales requires a little more work.  In this blog entry we illustrate how data binning can be used to aggregate large point-based datasets into hexagonal polygons to overcome the problem and improve the web map across all scales.

Well count aggregation web map

By Mark Smithgall, Esri Cartographer

Well Map Aggregetation Web Count - Thumbnail

This well count aggregation web map shows how a complex data source, such as gas wells in a producing field, can be aggregated and portrayed in an easy-to-understand manner.  This was designed as an ArcGIS Online web map to show the aggregation number as a proportional symbol of wells per administrative area.  In this case, three levels of aggregation were used based on the most logical administrative areas:  parishes, Public Land Survey System (PLSS) townships, and PLSS sections.

Using alternative thematic basemaps with ArcGIS.com map viewer

By Kenneth Field, Esri Research Cartographer

The default projection for all basemaps in ArcGIS Online is Web Mercator.  In a previous blog entry, Bern Szukalski explained using custom basemaps as an alternative to Web Mercator and the ArcGIS Resource Center provides information on how to build online basemaps.  Mercator projections are very useful for certain mapping tasks but not so good for others because they dramatically exaggerate northern and southern latitudes.  This exaggeration deforms the shape and size of areas.  Whilst Web Mercator has become a widely adopted web mapping standard (because of the tiling system being well suited to this spatial reference), there are situations where you may want a different map projection. In thematic mapping, for instance, you might want to preserve areas or shapes or even use a more pleasing view of the world than Web Mercator provides at small scales.   This blog entry describes how you can switch out the default basemap for your own, simplified thematic basemap.
