Geodata Community
For customers with large volumes of data, NoSQL databases provide a useful, highly scalable alternative to the traditional RDBMS. Developers can add support for read-only visualization and mapping of NoSQL data sources, such as MongoDB, into ArcGIS.
Plug-in data sources are a long standing method for displaying data in ArcGIS that is stored in non-traditional formats. MongoDB is an open source NoSQL document storage database featuring replication and data partitioning across multiple machines, robust ad hoc query support, and support for spatial indexing of simple points.
Developers can use the example code provided here as a starting point and reference for their own NoSQL plug-in data sources. Using the code sample will require Visual Studio 2010 C#, MongoDB’s .net driver, and the .NET Assemblies for ArcGIS.
Thomas Breed, who supplied the info for this post, talked about Plug-in data sources and MongoDB in the Effective Geodatabase Programming session at this year’s Developer Conference. You can find a video of that session HERE, Flash Gordon to about the 33:30 mark for the spiel on Plug-in data sources.
NetCDF (network Common Data Form) is a file format for storing multidimensional scientific data (variables) such as temperature, humidity, pressure, wind speed, and direction. Each of these variables can be displayed through a dimension (such as time, date, or depth) in ArcGIS by making a layer or table view from the netCDF file. The layer or table view represents one “slice” of the dimension (for example a single date or depth).

The cloud is the future of information technology.
This is the point Steve Riley was driving home in his keynote presentation at the 2012 Esri Dev Summit today. Being the CTO of Riverbed Technology, as well as having Amazon and Microsoft on his resume, he’s got some legit experience lending credit to his intelligent and animated dialog this morning on the paradigm shift into a cloud infrastructure.
“Change happens. You have to adapt or die” Riley pointed out. Adaptation is key to human progress. The wine press turned into a printing press (did that turn into twitter?). Smart organizations are getting in front of cloud technology and Riley laid out several steps he called architecture lessons for building a successful cloud implementation.

The geodatabase team is down here in Palm Springs for the 2012 Esri Developer Summit, and it’s the largest one yet with 1700 attendees!
The plenary session gave a good overview of the new functionality coming with 10.1, which is set to be released in June.
The morning was filled with well spoken Esri employees, most with amazing accents, giving everyone a glimpse into the future release.
Some highlights were new enhancements with ArcGIS 10.1 for Server, including new improved tools in server manager, publishing and sharing of services is now much easier, there were some good demos surrounding published geoprocessing services, lots of great ArcGIS Online improvements to facilitate building great maps and apps, and some good scripting examples which led to the unveiling of a new Python resource where you can find useful samples to enhance your GIS workflows: Cafe Python.

We’ve heard lots of feedback over the last few days from users who want to find the old “Insert your favorite” blog. Unfortunately the redirects we had in place when we deployed the new ArcGIS Blog pointed to its home page instead of these specific locations, leading to many unhappy readers. We have most of these redirects in place now & will have the rest completed today. If you’d rather not wait, here’s a table matching the old individual blogs to their corresponding URLs and RSS feeds in the new unified blog.

ArcGIS 10.0 Service Pack 4 (SP4) for English, is now available to our users for download via the ArcGIS Resource Center. This Service Pack contains performance improvements and maintenance fixes. Here are links to the downloads:
Release Note: ArcGIS 10.0 Service Pack 4 for the other five languages (French, German, Japanese, Simplified Chinese and Spanish) will be released in the next two weeks. A follow up blog entry will be posted to announce the availability once they are ready.
Have a question? Want to talk GIS? Looking for some good ideas? Jump into the conversation!
A few weeks back we rolled out some new features that we hope will improve the forums’ usefulness. One of the new features is the ability for those who post questions in the forums to rate the replies. In addition, any logged in user can also join in and vote on the various replies and conversations in order to help us identify the best information, helping you find good information more quickly. Another huge benefit to the new voting tools is that it helps us all identify, recognize, and reward those forums users who contribute the most helpful information.
Until June 2010, our old discussion forums (now archived) supported what we called the “Forums MVP Program”. Once every 6 months we would identify the Top 10 members of the community and make them eligible for MVP recognition and some valuable prizes.
