A Keyhole Markup Language (KML) file is a great way to view GIS data outside of ArcMap. Although there are many different ways to package and make data available, KML provides a simple format that can be viewed in a myriad of applications and can also be easily distributed to others.

Map layers can be converted to KML through the tools within the To KML toolset (ArcToolbox > Conversion Tools > To KML).

Although the tools within this toolset produce a KML quickly, the output lacks attribute data if not set up correctly. As in the example below, the KML only has the feature name. The name comes from the label expression of the ArcMap layer.

As you can see in the following screen shot, the Major Lakes Feature Class has some valuable attribute data that could be helpful if added to a KML file.Steps to Add Attribute Data to KML Files
1. Open Layer Properties of the layer to be converted to KML.
2. Click on the HTML Popup Tab
3. Check “Show content for this layer using the HTML Popup tool 4. Select the desired HTML formatting.
a. The table of visible fields is the default option and best for HTML content embedded inside geodatabase fields.
b. The URL is best for pointing features at a set of predefined HTML pages.
c. The formatted page based on an XSL template is best for advanced formatting.
5. Verify the HTML format.

A HTML Verification window will display an example of the popup.

Once you have the desired results, proceed to use either the Layer to KML tool or the Map to KML tool to create the KML file.

After you add the KML file to your application, you can see the added attributes for the features by clicking on it.

Hi all, my name is John, and I am a member of the ArcGIS Server team at Esri Support Services. Today I would like to share a few tips and knowledgebase articles that are useful for troubleshooting issues with ArcGIS Mobile 10:

1. The .wmpk (ArcGIS Windows Mobile Package) file generated from Mobile Project Center (MPC) is actually a compressed file. You may change the extension to .zip and upzip the file. You will see the .amp file and other .xml files.
2. The .amp file is the mobile project’s configuration file. You can use a text editor to open the file and check the MobileService URL and all other information configured in MPC. This is an easy way to check a mobile project without repeating the workflow. The MobileService URL should be using a fully qualified domain name or public IP address if the mobile project is intended to be used outside the internal network.
3. Below is a list of knowledgebase articles that reference common issues related to ArcGIS Mobile 10 project deployment and mobile cache:

FAQ: Is the Mobile Cache the same thing as the Server Cache? If not, why is it different?
ArcGIS Mobile uses sqlite database as the mobile cache storage format

Error: "MobileServer requires a custom extent to be set. The default extent is not acceptable (union of all layers"
Before publishing a map service with mobile data access capabilities, set the custom extent in ArcMap.

Error: "Failed to open the project. Error opening mobile cache"
The mobile cache needs to be manually copied over to the mobile project folder.

Error: "Error opening mobile cache" when deploying the mobile application on mobile device
A specific folder structure needs to be set on the mobile device.

FAQ: Can the ArcGIS Mobile application be customized?

The ArcGIS 10 Service Pack 1 (Desktop) Load Objects Command Patch is now available for download from the ArcGIS Resource Center. The download URL is
