There are a plethora of unanswered questions here. Are you using a shapefile? Do the coordinate systems of the two datasets match? As Dan mentioned, without more information it is difficult to make a suggestion. ... View more

So is the raster not able to be seen in the map, but will be in the table of contents?  The spatial reference error should not prevent it from being viewed, it indicates that the spatial reference is not recognized.  Can you right click on the raster in the table of contents and 'Zoom to Layer?'   If it still will not display then I recommend creating a Support call to have someone take a look at it with you. ...

The coarsest overview should cover the entire area as it should match the boundary file.  I would consider with your modified boundary, redefining and rebuilding all of the overviews. It appears as if the overview you have indicated is only a partial and has not caught up with the entire dataset.  Have you tried deleting the overviews and re defining them?  If you have tested that procedure then I recommend creating a Support incident to determine what may have happened. I have not had trouble creating mosaic datasets at SP2, then rebuilding the footprints as you have done and not lost the coarsest overview. ... View more

Can you indicate how large of an area you are processing?  Generally speaking the tool is not recommended if the size of the area being analyzed is larger that one degree of latitude.  In the help, there are other recommendations including the sky size, coordinate system and output options. In terms of the memory issue, the tool is very memory intensive and successive runs will create problems.  Have you considered using spawnV? Here are some forum posts that indicate some success with deleting the geoprocessor that way for intensive runs.  There are also more tips here. ... View more

To echo, what Curtis mentioned.  Take a look at the help documentation for the tool to understand what you should be comparing. If you are looking for someone to break it down with you, to see exactly what may be occurring, I encourage you to create a Support Incident and the Analyst should be able to explain it. ----------------------------------------------------------------------------------------------------------------------- Rectangle     The x,y position for the processing cell within the neighborhood, with respect to the upper left corner of the neighborhood, is determined by the following equations:      x = (width of the neighborhood + 1)/2      y = (height of the neighborhood + 1)/2     If the input number of cells is even, the x,y coordinates are computed using truncation.     For example, in a 5 x 5 cell neighborhood, the x- and y-values are 3,3. In a 4 x 4 neighborhood, the x- and y-values are 2,2.     The units for the width and height values can be defined in cells or in map units.     Focal statistics with rectangle neighborhood illustration ...

Since the clients are backward compatible, I believe by installing the latest version, the version of Microstation should be able to see the image service. I am not sure if upgrading versions of ArcGIS Image Server will correct the issue, from your previous description it appeared that issue was that the service was not seen at that version of Microstation.  The new client should allow the image service to be seen if the versions are now compatible.  You cannot add Image Services to ArcScene, only ArcGlobe and ArcMap. Per help, "You can simply add ArcGIS Online maps or imagery as a basemap layer in your ArcMap or ArcGlobe documents (as well as in ArcGIS Explorer)." ... View more

In a word, it is to maintain the spatial reference.  In Sketchup, the modeling is easy, but maintaining the spatial reference is not.  If you were to import a .skp through the Import 3d File Tool, the spatial reference will not be.  Per help,  "GeoVRML is the only format that has a defined coordinate system. The other formats tend to use local coordinate systems (in other words, centered on 0,0,0). In the latter case, the output shapes will need to be georeferenced." So make the necessary textures and custom look in Sketchup, and then Replace the spatially correct feature in ArcScene with the texturized model. Here is a tutorial discussing how to. ... View more

There are known issues with NoData values with ISDEF Image Services.  In order to accommodate the NoData, I would recommend creating Mosaic Datasets that can handle the NoData better and allow the statistics to be generated correctly if you are using ArcGIS 10. At ArcGIS 10, the footprints can be rebuilt properly and the statistics generated will be correct.  If you are using a prior version, then manual editing of the isdef is required. For more information about how to edit it properly, log a Support Incident. ... View more

There could be a few reasons why that error is occurring.  Since that error is related to python coding not working, there could be a lot of reasons.  Due to the complexity of some of the fixes, I would recommend logging a support call.  Sometimes there can be other third party software that is interfering and sometimes there are files that need to be deleted. Create a support incident and the Analyst will be able to walk you through the troubleshooting steps. ... View more

Per the help, image services can be added to mosaic datasets (isdef, iscdef, isref and rpdef).   There is also information on migrating to mosaic datasets.  Adding a 'mosaic dataset' raster type should bring in the original data. There may be a need to adjust the Min/Max PS when you have so many different mosaic datasets to ensure proper display. As the spatial extent of the new combined mosaic dataset will be vastly different from the original one.  I am not sure what processes may not be included during your import, but I would recommend placing a Support call for specific help with your complex dataset. ...

At ArcGIS 10, the terrain can be used in analysis depending on which one you select.  The TIN and Terrain Management Toolbox have some of the tools you can use on a Terrain.  Prior to 10, the terrain could not be used as inputs, but with the release of 10 it all changed. ... View more

Be sure you are using the most updated MicroStation Client. They should all be backward compatible.  This one is compatible with MicroStation 8.05 and 8.09 (V8 XM). ... View more

With polygons you can extrude the building footprints in ArcScene and then you can use the Layer 3d to Features tool.  This will create a multipatch feature class that will look like 3d buildings. Blog post on 3d Buildings Philadelphia 3d City Layer 3d to Feature Class ... View more

The Interpolate Shape tool will make the polygon 3d. It will create vertices that have the elevation value of the raster used to interpolate to.  The new file that is created will be exactly as the original one, but be a Polygon ZM and have 3d values.  So when you bring it into ArcScene the polygon will have values that reflect the new z vertex values.  The Add Surface Information tool will add the following.     Points�??z     Multipoints�??z minimum, z maximum, z mean     Polylines�??z minimum, z maximum, z mean, surface length, minimum slope, maximum slope, average slope ...

Perhaps a tool such as Multipart to singlepart will create a feature for each polygon and then run the Tabulate Area on each polygon will allow the process to complete.  http://help.arcgis.com/en/arcgisdesktop/10.0/help/index.html#//00170000003r000000.htm ... View more
