Kyle - are your cell sizes in the 3 rasters the same and what is the resampling parameter you're using in the Environment Settings? Regards, Robert LeClair Esri-Denver

A few things you may wish to try: - Right click on the folder containing the GDB, Go to properties > Security, Click add and grant read/write access to "everyone" - Right-click on the .gdb folder in Windows Explorer, go to Properties and uncheck the box next to 'Read-Only'.

One possibility for the Error 000229 code is after installing SP1 for Desktop Background Geoprocessing (64-bit) AND storing one's data in a Personal for MS Access geodatabase, the clip operation will fail. You may read more about this at: http://resources.arcgis.com/en/help/main/10.1/index.html#//002100000040000000 If this is not the case, then I would recommend calling Esri Support Services (Desktop) to create an incident so that an analyst may resolve the error.

Use the CAD to Geodatabase GP tool, fill in the mandatory parameters and click the Environments button. In the Environment Settings, click the Z Values dropdown and under the Output has Z Values, select Enable. It "should" preserve the Z values. Follow the same logic for M Values in the Environment Settings. Good luck!

Floyd - at 9.3.x, the Split Lines at Point (Data Management) doesn't exist as it does at 10.0. One option is to download the 10.1 Evaluation copy (Advanced) and complete your work. Please see the following URL for details: http://www.esri.com/software/arcgis/arcgis-for-desktop/free-trial Regards, Robert LeClair Esri-Denver

Derrick - I've yet to find anything within ArcGIS that creates cartograms, but I did find ScapeToad (free) that uses shapefiles as input/output. I haven't used it myself but it would seem to address your workflow. Regards, Robert LeClair Esri-Denver

Sarah - Have you considered using Hot Spot Analysis (Spatial Statistics Toolbox) rather than Kernel Density? There is a methodology one can use to regarding XY locations and distance band calculations. Some resources to consider: http://blogs.esri.com/esri/arcgis/2010/07/13/spatial-statistics-resources/ http://resources.arcgis.com/en/help/main/10.1/index.html#/Hot_Spot_Analysis_Getis_Ord_Gi/005p00000010000000/ Hope this helps!

Okay, I'm assuming this is your workflow - please correct me if I'm wrong. You have x number of rasters to create your cost surface. You used the RECLASSIFY GP tool to reclassify your rasters to the same "scale." Once all your input rasters have been reclassified to the same scale, you used the WEIGHTED OVERLAY GP tool to create your cost surface. Now you want the cost surface to have "good" cells dedicated to the preferred alternative. So what I would try is the EXTRACT BY MASK GP tool with the original cost raster as the input, the route as the Input Raster or Feature Mask Data and create a new raster (RASTER1) that is for the route. Then I would use the CON GP tool that uses an expression where VALUE IS NULL - would get a zero and non-NULLs would get a 1 or a 4 depending on what is considered "good" by you and create a new raster (RASTER2). The last step is to use the CON GP tool again where: Input Conditional Raster: RASTER2 Expression Optional: VALUE = 1 (or 4 - depends on what's good) Input True Raster or Constant Value: 1 (or 4 - depends what's good) Input False Raster or Constant Value (optional): Original Cost Surface Raster Output Raster: RASTER3 So in SUM, what this "should" do is extract those raster cells that "overlap" with the preferred corridor. Then you set a condition where it's preferred cell value or NULL. Then you set a condition where if it's preferred cell value, the raster cell gets a 1 (or 4) and the other cells get the original cost cell value. "Should" work...good luck!

To my knowledge, the web course was written for ArcGIS 10.0 but the concepts still apply at 9.3.x. With regard to 1=good and 4=bad, it's a human interpretation versus a computer interpretation. When you use the Weighted Overlay tool to create your cost surface, you have the option to create an evaluation scale of any form you wish. It's up to you to determine what's "bad" and what's "good." The key is to be consistent through the entire workflow. Make sense?

One workflow is to use the MINUS geoprocessing tool from the Spatial Analyst extension. Basically, it's subtracts the cell value in the 2nd raster from the cell value in the 1st raster and writes a new raster with the cell differences. Regards, Robert LeClair Esri-Denver

Jared - One way to learn more about the least cost path workflow is to register for the Distance Analysis using ArcGIS 10 web course. It goes into straight line distance and least cost path analysis workflows that may assist you. I teach the now retired Spatial Analyst class for Esri - feel free to email at rleclair@esri.com if you have specific questions. Regards, Robert LeClair Esri-Denver

Dave - The short answer to your question is - yes, each subtype can have it's own domain. One attribute field will be an integer and used for your subtype. Another attibute field (text, integer, float, etc.) will be for your attribute domain. The long answer is: In the Catalog window in ArcMap, right click the feature class and click properties. Select the Subtypes tab to build your subtypes based upon a short or long integer field type. On the lower right of the Subtypes panel, you'll click the Domains button to build attribute domains. You can build a specific attribute domain for aerial or buried if you wish or just one big attribute domain for both - depends on the attributes. Make sure your attribute domain field type (text, integer, float, etc.) matches the attribute field type (text, integer, float, etc.) After you build the domain(s), click OK and return to the subtype panel. At the top of the Subtype panel, select the first subtype - aerial or buried and then navigate towards the bottom of the subtype panel - you'll see "Default attributes and domains" - and for the ownership field, click the domain box to apply the specific domain to the subtype. Repeat this for the 2nd subtype. Click OK. Now you have a specific domain for a specific subtype. This workflow is described here: http://resources.arcgis.com/en/help/main/10.1/index.html#/Associating_default_values_and_domains_with_tables_and_feature_classes/001s00000009000000/ Hope this helps.
