Abdalla - In ArcCatalog, right click on the raster and select "Calculate Statistics" from the context menu.  You can then go into the Properties of the raster and see the Min, Max, Mean, StdDev, etc.  Hope this helps. Regards, Robert LeClair Esri-Denver ... View more

Bryan - Sometimes this error message is related to field names or table names not have the correct naming conventions.  I would recommend looking at Raster30 to verify that the field names don't violate conventions.  Please see the following URL for details:  http://support.esri.com/index.cfm?fa=knowledgebase.techarticles.articleShow&d=23087 Question for you - are you points stored in a Personal for Access geodatabase and is the output being created in the same Personal for Access Geodatabase?  If so, try to replicate the workflow in a file geodatabase.  Does the error message persist?  NIM062662 talks about this:  http://support.esri.com/en/bugs/nimbus/role/beta10_1/TklNMDYyNjYy Good luck!

Directly - no.  In ArcGIS 10, use the "Create File GDB" geoprocessing tool to create a 9.3 schema file geodatabase.  In the Catalog 10.0 window (or ArcCatalog 10.0), drag/drop features classes from your 10.0 geodatabase to the 9.3 geodatabase.  Then open a blank ArcMap 9.3 document and point to the 9.3 geodatabase feature class data. Good luck! Robert LeClair Esri-Denver ... View more

I have a book on my bookshelf to remind me of the "good ole" days - Arc Macro Language:  Developing Arc/INFO Menus and Macros with AML.  It's available on Amazon at the following URL:  http://www.amazon.com/Arc-Macro-Language-Vrsion-7-1-1/dp/1879102188 Good luck!

In ArcCatalog, right click on the Feature Class and select Properties.  In the Feature Class Properties window, select the Indexes tab.  Towards the bottom the Index GUI, select Recalculate for the Spatial Index.  It will update the Spatial Index for that feature class.  There's also a tool called Calculate Default Spatial Grid Index in the Data Management toolbox -> Feature Class toolset. Good luck! Robert LeClair Esri-Denver ... View more

Hi Chris - There's an Interpolate Shape tool located in the 3D Analyst Tools -> Functional Surface toolset that may do the trick.  It's output is a geodatabase feature class but you can export it to a PolygonZ shapefile if you like. Regards, Robert LeClair Esri-Denver ... View more

Pierre-Luc, If all your text/string fields have the same format, P4593, for example.  Then you could use the Right VB syntax to extract the 4 right most characters.  In this case my formula would be: NewField = Right ( [StringField], 4) This would extract the right 4 "characters" --- 4593 --- and put it into the Double field.  If the [StringField] is like P45931, then you would update the formula to be: NewField = Right ( [StringField], 5) Then 45931 is calculated into the NewField field. Hope this helps! Robert LeClair Esri-Denver ... View more

No, I don't believe so.  From the Help: The structure of the ASCII file consists of header information containing a set of keywords, followed by cell values in row-major order. There are two variations of the structure of the ASCII file. One identifies the origin by the coordinates of the lower left corner of the lower left cell, or as the center of the lower left cell. The format of the file in general is:     NCOLS xxx     NROWS xxx     XLLCORNER xxx     YLLCORNER xxx     CELLSIZE xxx     NODATA_VALUE xxx     row 1     row 2     .     .     row n The definitions of the keywords are as follows: NCOLS and NROWS are the number of columns and rows in the raster defined by the ASCII file. XLLCORNER and XLLCORNER are the coordinates of the lower left corner of the lower left cell. You can also use XLLCENTER and XLLCENTER to specify the origin by the coordinates of the center of the lower left cell. CELLSIZE is the cell size of the raster. NODATA_VALUE is the value that is to represent NoData cells. Cell values should be delimited by spaces. No carriage returns are necessary at the end of each row in the ASCII file. The number of columns in the header is used to determine when a new row begins. An example of an ASCII raster file is:     NCOLS 480     NROWS 450     XLLCORNER 378922     YLLCORNER 4072345     CELLSIZE 30     NODATA_VALUE -32768     43 2 45 7 3 56 2 5 23 65 34 6 32 54 57 34     35 45 65 34 2 6 78 4 2 6 89 3 2 7 45 23 5 ...

Here's a workflow you may want to consider: Run the ASCII to Raster GP tool (Conversion toolbox) If you have Spatial Analyst, run the Contour GP tool to create contours. (SA toolbox - Surface toolset) What you may discover is that the Contour tool will create stairstep contour lines.  To resolve this, run the FocalStats tool with a MEAN Statistics type and a default 3x3 rectangle neighborhood after you run the ASCII to Raster GP tool and then run the Contour GP tool.  This will create smoother contour lines.

Strange - working on my side over here.  I would recommend checking again and/or your internet connection. Regards, Robert LeClair Esri-Denver ... View more

I would recommend using the Feature Outline Masks (Cartography) tool (ArcInfo license) with the input layer being your annotation feature class, define the output and optional parameters.  Set the Layer Properties for the mask layer to no color, no outline.  Go to Advanced Drawing Options in Data Frame Properties and set the properties for Layer Masking.  Voila - "cuts" in the contour lines for your anno. Doesn't get away from the issue "I don't like the font" though... Robert LeClair Esri-Denver ... View more

If you have an ArcView license, you would only be able view (i.e. read-only access) relationship classes.  To create/modify relationship classes, you would require an ArcEditor or ArcInfo license level.  Please refer to the following link for additional information:  http://help.arcgis.com/en/arcgisdesktop/10.0/help/index.html#//004t00000007000000.htm http://help.arcgis.com/en/arcgisdesktop/10.0/help/index.html#/Relationships_and_ArcGIS/004t00000001000000/ Regards, Robert LeClair Esri-Denver ...

You may want to consider just adding the single raster dataset to ArcMap then.  As you mention, just click Add Data and point to where your raster datasets are stored. ... View more

In ArcMap, go to the properties for your Raster Catalog and create a SQL Query on the Definition Query tab.  Click OK.  Only those rasters that meet the SQL query conditions will show. Cheers, Robert LeClair Esri-Denver ... View more
