There is a local R user group in Portland, Oregon. R is a free software environment for statistical computing and graphics (http://www.r-project.org/). Their goal is to support and share R experience and knowledge among its users in the Portland community. They would like to hear how you use and enjoy the R language and statistical programming environment.

There are a ton of resources about using and understanding Spatial Statistics. The Esri Spatial Statistics team created this blog to make sure that everyone knows where to find them.

As we are discovering, there are often things we want to do but ArcGIS is not able to do them. Esri has created a Tool Gallery for people to share tools they have created when ArcGIS cannot do what they want. If you are thinking about creating a tool to do something you need, it is worth checking here first so that you don’t have to re-create the wheel.

Thanks to Max for bringing this paper by Mark Dale to our attention:
If you have shapefile or geodatabse feature class that you want to separate into several shapefiles or feature classes based on a specific attribute, you can do so relatively painlessly via XTools Pro. XTools is an extension that should be loaded onto any OSU owned computer that also has ArcGIS (at least this is the case for all computers in Digital Earth).
Once you have XTools toolbar added to your map, you can find the ‘Split Layer by Attributes’ tool under ‘Feature Conversions’. Caution: the tool requires the same input and output file types to work correctly (i.e., shapefile –> shapefiles or geodatabase feature class –> geodatabase feature classes).
There are many other useful tools worth exploring in XTools Pro (www.xtoolspro.com).
