Many of the menus and processes, such as the new geoprocessing toolset for example, have changed in ArcGIS 10.0. One of the biggest changes in ArcGIS 10.0 is the switch from Image Server to Mosaic Datasets. 
Previously, in Image Server, you could use the Advanced menu to manually control the options when adding rasters to an image service.
However, there are several situations where rasters added to an ISDEF should not apply the internal overviews that are present with some raster formats. SIDs, and other rasters with multiple levels of pyramids, can affect the performance of image services. Since image services use overviews to increase performance, increasing the number of overviews will improve the performance. 
When SIDs are added to an image service with the Advanced process under the General Tab, there is an option to "Include internal overviews". If this option is unchecked the raster will be added without bringing in the pyramids that are in the raster. For highly compressed rasters like SIDs, there can be many levels of overviews built into the raster which affects the number of overviews created by the mosaic dataset or ISDEF. 
In order to replicate the same workflow in ArcGIS 10.0, the Add Rasters To Mosaic Dataset tool includes a section of Raster Pyramid Options. In order to prevent the internal pyramids from being added to the mosaic dataset, set the value to zero (0). This increases the number of overviews that will need to be created, but the performance should be improved. If this option is not used, the overviews that are inherent with the SID will be used in place of overviews. So, the choice from a design perspective is  whether to utilize the overviews of the rasters added to the mosaic dataset or to create new overviews for the mosaic dataset. This pyramid option is available for all raster formats, not just SIDs.

Add Rasters to Mosaic Dataset dialogue with Raster Pyramid Options



To recap, the ability to apply or ignore the internal pyramids and pyramids of input rasters is available in the Raster Pyramid Options section of the Add Raster to Mosaic Dataset tool. Jeff S. - Geodata Raster Support Analyst
When using ArcSDE geodatabases, you may have noticed a change within the 10.0 release in how the upgrade process is now handled. Instead of using the Post Installation Wizard and selecting Repository Setup, as in previous releases, there is a new upgrade process. Upgrading your geodatabase is now performed within ArcCatalog using the new Upgrade Geodatabase (Data Management) tool.
The Upgrade Geodatabase (Data Management) Tool can be accessed in ArcCatalog via the Database Properties of a database connection under the General tab > Upgrade Status or within the Upgrade Geodatabase geoprocessing tool referencing an existing connection. For ArcSDE geodatabases, a direct connection to the geodatabase is necessary to run the upgrade.
 Post Installation Wizard at 10.0:
The Post Installation Wizard in 10.0 can be used for the following:
  • Defining Database and SDE DBA User - Creating new ArcSDE enterprise geodatabases
  • Repository Setup - Populate system repository tables (for new geodatabases only)
  • Authorize ArcSDE - Perform Software Authorization of the geodatabase
  • Create ArcSDE Service - If using application server service (when not using direct connections)

More changes are on the horizon to incorporate Post Installation functionality into the client tools for the 10.1 release, so stay tuned!

As you may already know, ArcScripts has been closed for adding new scripts. It was a valuable resource for sharing your tools with the community, but there is the new and improved Geoprocessing Model and Script Tool Gallery.

Whether or not you took advantage of ArcScripts in the past, now is the time to jump head-first into the new gallery. Spend some time browsing the tools that are available. Download and rate the tools, submit comments about the tools, and share the tools with your friends via social media.

This resource wouldn't be possible without the ArcGIS community.  Since you're reading this blog, you're part of this community. It's people like you taking the time to share resources that make this gallery so valuable. 

So, take a moment and think about the models you have built and the scripts you have written. Would others in this community find these same tools useful for their workflows? If so, consider uploading them to the Geoprocessing Model and Script Tool Gallery. The process is simple and can be done in just a few steps.

  1. Browse to the Geoprocessing content section of the ArcGIS Resource Center.


  2. Find the Model and Script Tool Gallery link on the left side of the page.

Here, you'll also find the following helpful resources: Submission guidelines and Submission checklist. The submission guidelines page will provide tips for organizing your data. The submission checklist page will help make sure you haven't left anything out, such as scrubbing your data, setting relative paths, or removing old results from the map document results window.

     3. Compile the tools and data into a ZIP folder according to the submission documents.

     4. From the Model and Script Tool Gallery page, click Add an Entry.

    

      5. On Add Gallery page, enter the information about your submission, upload a zip file for the tool and
          add a thumbnail graphic. Click the Submit button and you're done.

By following these quick and easy steps, you'll be on your way to sharing knowledge and experience with the ArcGIS community, helping others become more efficient in their workflows and processes.

The ArcGIS 10.0 Service Pack 2 (Desktop, Engine, Server) Geocoding general Maintenance Patch is now live at the Resource Center.

The patch addresses issues with locators in ArcGIS Desktop, Engine and Server that can cause the application to hang when an address contains specific characters. It also addresses an issue in ArcGIS Server, where the output spatial reference of a locator sticks and overwrites the default spatial reference of that locator.

For more details and to download the patch, please visit:

You’ve Got Mail

Posted by geonetadmin Jun 7, 2011
Let's pretend you've been tasked to build a geoprocessing model to automate some of your department's data management tasks while everyone is out of the office. Since ModelBuilder doesn't have any magic buttons for scheduling times to run or people to email, you're going to have to go "outside of the box" to make this happen and be the office hero.

Thankfully, there's already a handy technical article that outlines the steps for using Windows task scheduler to run the script at a prescribed time:HowTo:  Schedule a geoprocessing script to run at prescribed times

So, now things are running smoothly... until your boss requests an email be generated confirming successful completion of the job. You can either get to the office at dawn to verify and send out this email, or you could let Python do the work for you!

The script below is written to work so that an email is generated once the called model completes. When the model has finished, the email's subject displays, "Python script has completed," and the message body is populated with the geoprocessor results messages. The script can also be modified easily to meet new requirements as they are identified.Download Python ScriptDarrin C. - Desktop Support Analyst

Viewing a series of rasters according to a timeline usually ends with turning on/off the layers to produce the desired visual affect. This process, along with many other techniques for looking at data over time, has been fairly challenging. 

In ArcGIS 10, the ability to time-enable spatial data has opened a whole new dimension to the visualization of information.

Imagery, temperature and precipitation are just a few examples that can be placed into a mosaic dataset or raster catalog to represent a change over time. The following example enables time on a mosaic dataset. However, similar steps can be followed to activate time on a raster catalog.  

Preparing your data:

1. Create a new mosaic dataset and add in the rasters.

(For detailed steps see: The workflow and tools to create mosaic datasets)

2. Open the attribute table of the mosaic dataset footprint.

3. Add a new ‘date' type field.

4. Populate the field with the corresponding time values.

Enabling time on your data:

1. Right-click on the mosaic dataset in ArcMap > Properties > Time tab.

2. Select the Time Field.

3. Click Calculate to populate the time step interval and the layer time extent.

4. Adjust the time step interval to the desired value.

5. Click OK.

6.      Open the Time Slider window from the Tools toolbar.

 

7.      Enable time on map from the Time Slider window.

 

8.      Use the time slider to step through each raster in the mosaic dataset.

 

Now with time enabled functionality, your rasters can know what time it is and provide you with an excellent option for visualizing data changes over time.
