Tyler - I believe this has to do with the Business Analyst extension.  First question - have you purchased BA?  If not, then you would not be able to access the python components for BA. If you have a BA license, then you can access extensions via Python.  Please refer to the following webhelp: http://help.arcgis.com/en/arcgisdesktop/10.0/help/index.html#//002z0000000z000000 Hope this helps.

I don't believe there is a way to do this IN ArcGIS Online but you could create the ArcMap Join in the Desktop software, export the layer to a new shapefile, and then import the new shapefile into ArcGIS Online. Hope this helps! Robert LeClair Esri-Denver ... View more

Juliane, A few ways to do this: One way to do this is if you have a polygon feature class for water, set this as a Mask in the Raster Analysis Environment Settings.  From there, open the Raster Calculator and set the map algebra statement to be bathymetry raster as the only input and define the output raster.  The mask will "clip" the raster for those areas that the water and bathymetry raster intersect. Another way is to use the Extract by Mask geoprocessing tool - even easier!  Define the bathymetry as the input raster, the water as the mask, and define the output raster. Good luck!

Giacomo - A few options to consider - ArcGIS for Home Use Program (Version 10.0) - http://www.esri.com/arcgis-for-home/index.html ArcGIS for Desktop Free 60-day Trial - http://www.esri.com/software/arcgis/arcgis-for-desktop/60-day-trial.html Good luck! Robert LeClair Esri-Denver ... View more

I see - Esri GRID format is similar in composition to an ArcInfo coverage (i.e. a folder/workspace/etc) in the sense that it requires the INFO directory.  The INFO directory stores the attributes for the raster dataset as well as other items.  So if you're boss only emailed you the GRID folder without the INFO folder, then bad things are amiss.  This may be the root of the problem. ...

Abdalla - What is the format of your raster datasets and are they stored in SDE by chance?  If so, it could be a permissions issue. Regards, Robert ... View more

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.

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 ...
