Hi Megan, You may be encountering a bug that is now resolved in ArcGIS 10.1: NIM060270  Compressing and Uncompressing a file geodatabase with the  Preview Tab open in ArcCatalog corrupts the last feature class previewed As a workaround, try exporting the feature class to a shapefile and see if you are able to preview the shapefile. ...

Hi Lila, Spatial Resolution refers to the cell size (the area covered on the ground and represented by a single cell).  See here under 'Types of Resolution'.  Therefore, if the cell size is 5 x 5 meters, the resolution is 5 meters. You can check the cell size by right-clicking on the raster dataset > Properties > Source tab.  If your coordinate system is in a Geographic WGS 84 coordinate system, you will want to project your raster to a projected coordinate system with Meters for the linear unit.  You can do this using the Project Raster tool. ...

Try copying the MDB to your local disk and see if you receive the same error. ... View more

You won't have to do any additional steps to convert you MDB to a PGD.  For example, if I create a MDB in Access I can immediately begin to use this with ArcGIS.  I can import/export feature classes, create tables, etc. with the database. ... View more

Hi Randy, Personal Geodatabases are Microsoft Access databases that can store, query, and manage both spatial and nonspatial data.  See here.  You should have no problem accessing a Microsoft Access MDB using ArcGIS 10.0. ... View more

Hi Ken, I would ask the user that sent you the geodatabase to create a new geodatabase using the Create File GDB tool.  With this tool they can specify a specific version of the geodatabase, i.e. (9.2, 9.3. 10.0, etc).  Have them specify 9.3 and then copy/paste the data to this geodatabase. ...

Hi Mike, It looks like you may have discovered a bug.  I was able to reproduce the same behavior using ArcGIS 10.1 SP1 and SQL Server.  I would recommend following up with Tech Support to verify this, and to have this bug logged with your customer information attached to it. As for your workaround, I don't see any problems using this.  I ran a test and everything appeared to work.  I also verified that the delta (A & D) tables update correctly, as well as the SDE_STATES table. ...

Hi Stephen, Does the raster contain a colormap?  If it does, this is a bug and the raster dataset won't open in 10.0.  As a workaround, use the Copy Raster tool to export the raster dataset to the 10.0 geodatabase and check the option 'Colormap to RGB'.  This will create a 3 band raster, but all of the colors will be maintained. ...

Here is an example: mxd = arcpy.mapping.MapDocument("CURRENT") df = arcpy.mapping.ListDataFrames(mxd)[0] df.zoomToSelectedFeatures() ... View more

You could use something like: import arcpy input = arcpy.GetParameterAsText(0) cur = arcpy.SearchCursor(input) for row in cur:     geom = row.Shape     X = geom.centroid.X     Y = geom.centroid.Y     XY = str(X) + ", " + str(Y)     del row, cur arcpy.AddMessage(XY) Here the X,Y coordinates are stored in a variable XY.  For the input parameter, you will want to set the data type as Feature Set. ...

If all of these services are accessing data from your SDE Workgroup geodatabases, you are at your maximum connections.  Set your 'Maximum number of instance per machine' to 1.  You can do this by right-clicking on each service > Service Properties > Pooling.  This way an additional database connection is not attempted if a simultaneous request is made on a service. ...

Hi Kevin, Set the data type to Feature Layer for the input parameter instead of Feature Class. ... View more

What version of ArcGIS are you running?  With the original code I sent and you test data, it reported each segment touched another segment successfully.  I am currently using ArcGIS 10.1 SP1. ... View more

Hi John, The extent is created from two XY locations from two mouse clicks.  If you want the extent, you would click in the lower left corner and the upper right corner for the area of interest.  If you just want a single location you would just specify one mouse click and execute the tool. ...
