New Support Center Contest Winners

When we launched our new Geocortex Support Center in 2011, we challenged members to participate in our Discussion Forums by sharing knowledge,  and helping to build a strong, vibrant Geocortex user community. Prizes were offered to acknowledge key community contributors. The first contest was such a success that we ran a follow-up contest that ended on Valentine's Day (Feb 14).

A drum roll please....

After reviewing five months' of forum contributions and feedback, the Geocortex Support Team is ready to announce the winners!

Congratulations to Brad Fisher, our MVP and winner of the $1000 prize. Brad's work with Critigen on the Thames Tunnel  enterprise GIS, built on ArcGIS Server and Geocortex, provides effective tools to analyse, visualize and access information. Brad cites Geocortex’s ability to rapidly deploy feature-rich, secure map browsers as central to this important project's success. Brad has been consistently active on the Forums for the  duration of this contest, and has been a great community contributor.

Kudos also to Mike Hargreaves, another significant and helpful contributor to the Forums, who has been selected for the $500 prize. Mike is responsible  for the delivery of both WebADF and Geocortex Viewer for Silverlight interactive maps for both internal and public-facing audiences in the City of Santa Rosa.

A big "Thanks!" to both of you.

Although Brad and Mike are being specifically acknowledged, the Latitude Geographics Team salutes all contributors to the Geocortex Discussion Forums. We're thrilled to see this community thrive, grow, and help each other succeed with Geocortex software.

We're readying the next Support Center contributor contest...

Stay posted. We're really pleased with what the community has provided to date, and want to encourage contributions to the new Geocortex Code Gallery. Another iteration of our contest will run again soon.


Add Data Location

I regularly use data from different sources (SDE connections, network drives, over a VPN, etc).  In the past, I often found that if I closed out of ArcMap, the next time I opened it and tried to add data it would have to spend time trying to re-connect to a folder that was no longer accessible.  Sometimes this could take ages.

I used to get around this by trying to remember to add some local data to ArcMap before I closed it (not a very reliable work-around, as more often than not I would forget to do this).

The more reliable solution is a quick Options setting in ArcMap.  Under Tools > Options > General Tab, uncheck "Return to last used location when Add Data dialog first used".


ArcMap layer list and map colors are different

I found a solution for an irritating problem - some of the symbol colors in my ArcMap layer list were different than those in my map:

wrong colors

Turns out it required a simple display setting change. Right click on the desktop and hit properties to open the Display Properties window. Click the Effects button under the Appearance tab:

Select the "ClearType" method to smooth edges of screen fonts:

Problem solved!

Field Data Types

Have you ever tried to join data in ArcMap only to find that the field you are trying to join on does not appear in the drop down menu?

join_field2

Chances are your field data types do not match. For example, if one of your joining fields is type "Text" and the other is type "Double", ArcMap does not recognize a match between values in those fields. Text will be read as a string of characters (which can include numbers), and Double will be read as a numerical value. A text number does not equal a numerical number as far as ArcMap is concerned.

The simple solution is to convert the field data type in one of your datasets to match the other, and then you should be able to join them.


More Info on Tool Errors and Warnings with 9.3

ArcGIS Desktop 9.3 help offers a new section on Tool errors and warnings, which can be a great help when you receive an error code but are not sure what it means. Search for your error code, or navigate through the 9.3 help index (under Geoprocessing tool reference) for a list of error codes from 1 to the infamous 999999. They offer a description and solution for each error code which can help get you on your way faster. Don't forget to search the ESRI Support Center User Forums as well if you are still stuck - chances are someone else has experienced the same issue and you can pick up some tips.

Caching Imagery with a Raster Catalog

One way to increase the performance of imagery in your map service is to cache it. Since it greatly reduces the amount of time required to render the imagery on your map, caching will allow you to show your imagery at a far greater extent than you could if it were being brought in dynamically. While imagery may lend itself to caching, I find on occasion it can be a bit troublesome to get the caching going. I had a bout of Error 999999 with my latest caching project - turns out 1400 sid images covering an entire county was a little more than ArcCatalog could chew. Fair enough, I had experienced similar issues before where I couldn't even get my ArcGIS Server map service to start because I was throwing too much imagery at it.

Enter the Raster Catalog. Using an unmanaged raster catalog as opposed to a managed raster catalog saved me a bundle of raster catalog loading time. While the managed raster catalog can take as long, or longer, than your cache creation time - so in my case, a day or two - the unmanaged raster catalog takes far less time to create and load - for me, under two hours.

And thanks (many, many thanks) to ESRI Support and the Color Balancing option in ArcMap, my previous misconception that raster catalog image quality had to be poor compared with the original imagery, is a thing of the past - and I have the completed cache to prove it.


Tabbed pages in Sharepoint

I’m always on the lookout for ways to improve our Sharepoint sites, especially for ideas on better organizing content on the page. I recently found this page template for a tabbed Sharepoint web page. I immediately uploaded the template and put it to work on several internal projects. Suddenly gigantic pages of confusing information were all tidy and well organized!

Implementing the page is really simple. You just upload the file and get to work, adding web parts like you would any other page in Sharepoint. You change the names of the tabs by modifying the web part and choosing to edit the source instead of using the rich text editor. It also works well in Sharepoint Designer, if you’re doing more complicated pages.

Shortly after testing it out on our intranet, I was tasked with updating our forums on the Geocortex Support Center. With the release of Geocortex 2.0, we decided to add forums specific to API development for our new REST, Flex, JavaScript, and Silverlight APIs, which was a perfect time to update the Discussion Forum page. The tabbed interface gave me a way to present all of our forums without making our visitors scroll down the page to see them, giving the page a nice, crisp new look.


MXD file size

Have you ever noticed that your MXD file size sometimes increases, even when you haven't added any new data or symbology? I had noticed it a number of times but until now could offer no explanation for it. I was interested to learn that MXD files may grow in size after being saved multiple times because they can become fragmented. Saving a fragmented map document as a new document may reduce its file size.


Suddenly ArcCatalog won't open...?

The ESRI user forums saved the day once again. I couldn't get ArcCatalog to work all of a sudden - it was taking a very long time to open, and when it finally did open, it wasn't responsive and kept hanging. If you are experiencing the same problem, try renaming your Normal.gxt and ArcCatalog.gx and let ArcGIS recreate them on its next startup. The problem could be that they have become corrupt. You will find them in the folder C:\Documents and Settings\User Name\Application Data\ESRI\ArcCatalog - where User Name is the user name you use to log on to the computer.

I renamed both files, and ArcCatalog started up in no time.
