Moving Service Layer Credits 10.1

If you’ve started using 10.1 you’ll notice the new service layer credits of basemaps appears in the layout window. What you might not know, is that while you can’t remove the service layer credits due to licensing agreements, you can move them using the dynamic text function.

Go to main menu at Insert > Dynamic Text > Service Layer Credits

You’ll then have the flexibility to move, resize, and change the font of the text.

Workspace Clip Geoprocessing model

I’ve had a few requests in recent training courses for a model that will clip a base dataset to a specific project area. Say, for example, you have several regional datasets like roads, rivers, cities, and vegetation, and you need to clip them all to your study area. What’s a quick and easy way to do it? I recently found this great geoprocessing model called Workspace Clip.

This model takes base data stored in a workspace  folder, geodatabase, or feature dataset, and creates a subset based on a study area. If, for example, I have an urban planning project for an area in Wollongong, I can run the model to create a subset of my regional data based on my project boundary. You can see the output below. The top image shows the original dataset, and the bottom image displays the clipped output.

The model quickly created base data for my new project, so I can begin analysis and planning faster!

Geotiff issue in version 10

If you are having issues with GeoTIFF images that were viewable in ArcGIS 9.3.1 but not visible in ArcGIS 10 read on!

  1. Click Customize on the Main menu and click ArcMap Options (or ArcCatalog Options, depending on the application you are using).
  2. Click the Raster tab in the Options window.
  3. Within the Raster tab, click Raster Dataset and check the Use world file to define the coordinates of the raster check box.
  4. Click OK.

The Tif images are now viewable in ArcGIS Desktop 10! See this help item for more information.

Uninstalling service packs at 10

Need to roll back to a previous service pack or uninstall a patch? A new function with version 10 is the ability to unistall service packs. This is helpful if you run into an error or performance issue and need to test if the service pack is involved.

If you are using Windows XP, you can use the Add/Remove Programs window to view and uninstall service packs or patches. For more details visit this link.

But if you’re using Windows 7, the workflow is slightly different.

i)     Open Control Panel

ii)    Navigate ‘Programs and Features’-> ‘View installed updates’

iii)  Navigate ‘ArcGIS Desktop 10 Service Pack x’-> Right Click and Uninstall.

A PDF Version of ArcGIS 9.3 Style Galleries

Recently, I had the task of symbolising a road reporting map for a local client. To help this client choose appropriate symbololgy to create the look and feel they wanted for the map, I needed a document showing the contents of Esri’s style galleries. After a bit of digging, I found this PDF  showing a catalog of the symbols included with the 9.3 release:

It’s an excellent starting point if you need to plan or document symbology at the beginning of a project.
[Note: Even though ArcGIS 10 does not yet have a version of this 9.3 document, many of the symbols are the same. If a version of this document becomes available for ArcGIS 10, we will be sure to post it—so stay tuned!]

Extending ArcGIS 10 editing capabilities with new add-ins

I was exploring ArcGIS.com this morning and came across an excellent resource I wasn’t aware of and wanted to share.  It’s called ArcGIS Editing Labs.

This site is a warehouse for various tools and models designed to enhance your editing experience and improve editing workflows. Two tools in particular caught my eye: the Auto Complete Freehand Construction Tool and the Cut Polygons With Circle Tool.

Time-Enabled Rasters

Visualizing change over time is an effective way to analyze local or global trends and predict future scenarios.

In GIS, much information of this type—for example, sea-surface temperature, annual births, labour market statistics, vegetation type, land-use data—is commonly stored in raster format, and it’s very useful to see these data animated. So how do you make your rasters time-aware? An easy way to is to take advantage of two new features available in Version 10: time-enabled layers and the mosaic dataset.

Follow these steps to create an animation showing change in sea surface temperature over time, or vegetation change in South-West QLD. There’s a tonne of data to show change over time—and now we have an easy way to visualize it in ArcGIS!
