7/13/09–As mentioned when we announced the new ArcGIS Online Sharing Application a few weeks ago, better sharing of geographic information is enabled in part via new ArcGIS technology that allows layers referencing feature or raster data to be packaged into a single “layer package”, comprised of both the layer cartography and data. These layer packages can be shared with other users via files, e-mail, or the new ArcGIS Online sharing capability.
Learn about Layer Packages, ArcMap, ArcGIS Online, and ArcGIS Explorer 900 in the GIS Education Community Blog.
For tutorials on layer packages, see A tutorial for creating good layer packages and Creating layer packages part 2 – using group layers in the ArcGIS Explorer blog.
7/9/09—Several new maps were added to ArcGIS Online this past week. As mentioned in our earlier announcement in May, this includes several maps in the Google Maps/Bing Maps tiling scheme. These consist of 12 USA demographic maps featuring recently released 2009 data from ESRI’s demographic data team, a world terrain basemap and a world reference overlay map designed for use with thematic maps like demographics, and a world basemap from DeLorme. Also included is a new world topographic map that was compiled to uniform cartography from best available sources assembled from data providers such as the USGS, EPA, FAO, NPS, AND, and TANA. Learn more about the world topographic map in the ESRI Mapping Center.
In addition, a few final updates and additions were made to maps in the traditional ArcGIS Online tiling scheme. This includes a new World IKONOS Cities Imagery map with high-resolution imagery for over 700 metro areas around the world, designed to be overlaid on the USA Prime Imagery or other imagery basemaps. Lastly, there was an update to our world user imagery map with high-resolution imagery for the State of Pennsylvania and Ventura County, California.

6/23/09–The World Imagery services (ESRI_Imagery_World and ESRI_Imagery_World_2D) were updated with more recent imagery for the United States and with new high-resolution coverage for metropolitan areas around the world. The services now include GeoEye IKONOS 1m imagery for more than 875 cities and 1,200 towns worldwide plus USGS 15m Landsat imagery for Antarctica. In addition, approximately 40% of the imagery in the United States was updated with more recent imagery.

The routing capabilities are based on Tele Atlas 2008 reference data for North America and Tele Atlas 2007 reference data for Europe. The routing services enable you to generate routes and driving directions for two or more points with a limit of 5,000 routes per year, including 10 route stops and 25 barriers per route. For external commercial use of ArcGIS Online routing tools, or if you want to create more than 5,000 routes per year, subscriptions are available in blocks of 5,000 routes, including 20 route stops and 250 barriers per route.
For information on using the routing tools with the ArcGIS software of your choice, see Using free routing tools on the task server.
6/2/09-This evening from 5 PM PST to midnight, ArcGIS Online will undergo system upgrades to improve our infrastructure. These system upgrades will provide a more robust environment to support ArcGIS Online services usage today and as it continues to grow. Tonight’s upgrades will be made for the system that supports ArcGIS Online premium (subscription) map services (i.e., premium.arcgisonline.com). We anticipate minimal impact to your applications during this time, but you may need to reconnect to the ArcGIS Online premium servers. However, if you experience any ongoing service availability or performance issues as a result of this change, please post a description of them to this blog.

5/6/09—At the ESRI Developer Summit, ESRI announced that it would be
migrating its hosted ArcGIS Online map services to the Google Maps/Bing Maps (Microsoft
Virtual Earth) tiling scheme with the next major update in
2009. This change is in response to feedback from many ArcGIS users who
have requested that ESRI use a common map tiling
scheme matching other popular online map providers. The new services
will particularly enable ArcGIS web developers to more easily combine
popular web map services with ArcGIS Online map services including
those from Microsoft Virtual Earth, Google Maps, and other providers
that use the same web map tiling scheme.
ESRI will introduce the updated services with the next major update
Online map services planned for Q3 of this year. A few new map services
will be released in advance of the full service migration, which will
allow a preview of ArcGIS Online map services in this new tiling
scheme. ESRI will continue to host the existing ArcGIS Online map
services (e.g., World Street Map, World Imagery, etc.) in their
existing ArcGIS Online tiling scheme through Q1 of 2010 in order to
give users ample time to migrate their maps and applications to the new
3/16/09—Address locators for Europe and North America, and a world places locator are now available on the ArcGIS Online Task Server. These free tasks are available to use in your ArcGIS applications.
The geocoding and place finding capabilities are based on Tele Atlas 2008 reference data for North America and Tele Atlas 2007 reference data for Europe. The address locator services support single address, reverse, and batch geocoding of up to 1,000 batch geocodes in a year. For external commercial use of ArcGIS Online tasks, or if you want to perform more than 1,000 batch geocodes in a year, you must purchase a subscription.
For information on using the locators with the ArcGIS software of your choice, see Using free geocoding tools on the task server.
3/6/09—ArcGIS Online was updated Friday night, March 6, to address an issue that was reported recently when connecting to ArcGIS Online map services in web applications. Common web application errors encountered were:
- “An error occurred while processing your request.” or
- “Client found response content type of ‘text/html’, but expected ‘text/xml’.”
If you experience any ongoing service availability or performance issues related to this change, please post a description of them to this blog or contact ESRI Support.
2/3/09—The World User Imagery 2D map and 3D globes, CSP_Imagery_World_2D and CSP_Imagery_World, were updated with imagery for the UK Channel Islands, Portugal, and San Diego County 2007 fire areas. The UK Channel Islands map content is 1m resolution, aerial imagery
provided courtesy of DigiMap Ltd. The Portugal map content is 1m
resolution aerial imagery for the entire country of Portugal, provided
