It can come into play if you check the Unsplit Lines parameter in the DISSOVLE GP tool. By doing so, lines are only dissolved when two lines have an end vertex in common. Regards, Robert LeClair Esri-Denver

This behavior makes sense. If your input for the Euclidean Distance GP tool is a raster with all cell values being 0 and 1's, then these are all valid values. As a result, there is no cell to cell distance to measure. What you need to do is determine the cells values to measure from. For example, let's say you're interested in only the cell value of 1 and not the 0's. Then you would need to run the Set Null GP tool first to set the zero values to NoData. The parameters would be as follows: Input conditional raster: your input raster Expression: Value = 0 Input false raster or constant value: 1 Output raster: new raster The output "new raster" will only have values of 1 and NoData. From there, run the Euclidean Distance on the new raster. What is the result? Please advise. Regards, Robert LeClair Esri-Denver

Julia - do you have an ArcMap Join to your raster by chance? If so, I'd recommend the following steps to resolve this issue: 1. Disable the Background process (Geoprocessing menu > Geoprocessing Options) 2. Increase the "Maximum number of unique values to renderer" value to maximum number (Customize Menu > ArcMap Options > Raster tab > Raster dataset) 3. Set the internet security level to Low (Internet Explorer > Internet Options > Security) Does the error message persist? Please advise. Regards, Robert LeClair Esri-Denver

Jim - right click on the data frame and choose Properties from the context menu. Click the General tab and towards the bottom, click the dropdown for Label Engine and select ESRI Standard Label Engine. Voila - back to standard labeling. Hope this helps, Robert LeClair Esri-Denver

Darlene - Here's a thought - instead of using the CON function, try the Raster Calculator instead with the following syntax: Con(IsNull("Corrected_DEM"),�?�Original_DEM, "Corrected_DEM") What is the result? Please advise. Regards, Robert

Understand Darlene - no worries. I too am an "old" dog as well - ArcInfo Workstation (v. 5.0). Progressed through ArcView 1.0, 2.0, 3.x and now the ArcGIS releases v. 8-10.0. Cheers!

Darlene - interesting...I'm assuming your rasters are in the same projection, correct? If you're interested, you can send me your rasters to rleclair at esri dot com. I can work with the scenario and attempt to resolve it. Please advise.

Darlene - Would this work in the tool GUI: Input conditional raster: CORRECTED_DEM Expression: NOT("VALUE" IS NULL) Input true raster: CORRECTED_DEM Input false raster: ORIGINAL_DEM Good luck! Robert LeClair Esri-Denver

Dave - The fastest and easiest way to populate your subtype field is use "Select by Attributes" and select the records based on a particular attribute value. For example, Type = "Interstate". From there, use the Field Calculator and calculate the subtype field to the appropriate subtype code (i.e. Subtype_Field = 1) Do this workflow for the remaining 14 subtype codes. There are other ways to select features as well - manual approach and then use the Field Calculator. Hope this helps! Robert LeClair Esri-Denver

Stephanie - I'm not a VB Script or Python person and I'm sure there's some code that would do it easier than my suggestion. There's the Standardize Addresses that breaks up your addresses into multiple fields. From there you can create a new address field and concatenate the address fields you wish to keep into one field and delete the rest. Good luck! Robert LeClair Esri-Denver

Nicolai - by chance are you using VBA code blocks for the field calculations? These are no longer supported in the ArcGIS v. 10 field calculator. Possible workaround: Use Python or VB Script code blocks in the Field Calculator. Another possibility is to request a VBA authorization file from Esri keycodes - http://blogs.esri.com/Dev/blogs/arcgisdesktop/archive/2009/10/28/ArcGIS-Desktop-and-VBA_3F00_.aspx Good luck!

The workflow IsNull and Con functionality outlined here: http://help.arcgis.com/en/arcgisdesktop/10.0/help/index.html#//009z000000ms000000.htm could be combined in ModelBuilder and run as a single process. The user would set the necessary parameters for input to apply to different input raster datasets. Just a thought... Regards, Robert LeClair Esri-Denver

Hi Ferran - Instead of the raster calculator, I would use the CON geoprocessing tool in the Spatial Analyst toolbox. The syntax for the GP tool would be as follows: in_conditional_raster = your input raster in_true_raster_or_constant = 0 in_false_raster_or_constant = your input raster where_clause = VALUE IS NULL If the raster cell evaluates as TRUE (i.e. IS NULL), the cell gets a value of 0. Else if the raster cells evaluates FALSE (i.e. IS NOT NULL), then the raster cell gets the original input raster cell value. Good luck! Robert LeClair Esri-Denver

Do the data types for the attribute field match the data type for your domain? For example, text to text, short integer to short integer, float to float, etc... This is one reason why one would not see a coded value domain available for an attribute field. Regards, Robert LeClair Esri-Denver
