I am not sure what a FIT file is, but in ArcScene you can control the quality of the raster as described in this blog.  Remember that ArcScene loads everything into memory, so that larger rasters can cause other display and performance issues if the quality is raised. I recommend testing out different sizes and qualities to see what works best for you. ... View more

I am not sure what to say about your testing. What was the overview factor you chose?  What did the Analyze Mosaic Dataset reveal?  I am also not sure what you did with rebuilding the footprints, most of the time the reason to rebuild the footprints has to do with the presence of NoData in the rasters. The footprints will remove that information from being displayed. If the source rasters are beings referenced too much then it would not be an accurate comparison.  I would pay attention to the spread in the Min/Max PS with the mosaic dataset.  If you have a large range then that may be the issue.  Ideally with the overview only raster this should happen really quickly.  So the Max PS of the source rasters should be much lower than with the pyramids. In testing here, the mosaic dataset has always performed faster when designed correctly. Also with the more data you add, the more the performance difference will be revealed.  The larger the mosaicked raster dataset gets, the more unwieldy it will become. I am including the help documentation on the recommended mosaic dataset building and a discussion of overviews vs pyramids.  Another consideration should also be the time it will take to produce the raster dataset.  The mosaic dataset creation process is much faster than creating the raster dataset.  For further performance once you have the image service created, caching will push the image service to even better performance.  I would further recommend contacting Support to demonstrate the performance issue that you are seeing. ...

Remember the speed of the mosaic dataset comes from having optimized source rasters and the use of the overviews.  In terms of your questions, I think that you could try it each way.  For instance, when adding the rasters to the mosaic dataset, you can choose in the options to set the max pyramid level to zero.  Then generate overviews normally.  This will force the mosaic dataset to ignore your pyramids and generate more overviews.  In some circumstances, this is preferable. However, I would still create a similar test mosaic dataset with the pyramids added to see how that performs.  The hardest part of making recommendations like this is that while there are recommendations that work in some situations, each raster dataset might be slightly different.  Finally, I would leave off the option to generate pyramids as you already have them and I would think there is not as much difference with regard to performance between the versions of geodatabase. What will be different is the functionality that is only available at 10.2 will be lost.  Also don't forget to Analyze your mosaic dataset for specific recommendations. ... View more

Esri GRIDs are 32 bit float by default. I am unsure what an ArcGrid is, but if you mean Esri GRID raster or an extensionless raster then it should be float already.  I would be sure to project your data from WGS 1984 if you desire to use the NED files directly. Be sure that you have the elevations in meters and then choose a coordinate system based on meters.  That will make your calculations come out correctly. ... View more

The exported multipatch should exhibit the same qualities as the extruded polygon.  If you are not getting the same effect, then I would consider what has changed.  Are you using a different coordinate system or switching units?  Something has changed and I would look into the creation of the multipatch as their isn't a mechanism in ArcGlobe/ArcScene to modify a multipatch. You could start from the polygon in City Engine and then drag/edit it there. ... View more

Have you tried to delineate the triangles?  That may be the best option, unless you have a polygon at the outside of your data to use as the clip. ... View more

What is the input format prior to the clip?  If it is trying to create a 32 bit raster then that is the problem.  I would stick to a .tif, Esri GRID or .img format. PNG is usually not an output format for hillshades.  Check the Supported Raster Formats for ideas on format and look at .png and notice that you can only have certain output formats. ... View more

Consider the coordinate systems you have in the map document. Ideally, you should have one reference raster in the coordinate system you are trying to put the unreferenced file.  Any combination of multiple coordinate systems or particularly if the data frame and the target coordinate system are wildly different. ...

For file based mosaic datasets, the default location is in a folder where the geodatabase is located.  The location for SDE mosaic datasets defaults to inside the database.  You must use the Define Overviews to alter this location.  There are settings for the compression, resampling method and compression quality that can be altered within that tool, but the overviews are always tifs. ...

Normally you would look at the source properties on the sid, but at this point I would suggest to follow Luke's suggestion of the viewer. If you cannot see the sids with the viewer, then they have been corrupted and will need to be downloaded or if they download is correct the vendor needs to be contacted to upload the correct version. ...

Have you tried the Clip tool?  With the geometry option chosen, the output should be what you want.  With your Extract by Mask output, did you check to see if a stretch was applied to it? Or more importantly, check the symbology options were different?  I would start there, the tool will not change the values unless it needs to resample and then only slightly.  However, if there were no statistics before or not a stretch applied, then the look of the raster will be different. ...

Lisa Nice blog post, that was the one that I provided in the hyperlink of the word blog above. If the overviews are the checkerboard, then you have to confirm on the attribute table of the footprint that they were actually generated.  If they were generated, then try to use the path specified by them where you are trying to access the mosaic dataset.  You should not be able to hit that folder if it is a permission issue, so you will have to allow the user to access those overviews via folder sharing/security.  If they have not been generated, then use the Build Overviews tool.  Remember that the checkerboard is the default behavior when either the source raster or overview cannot be seen, but has been created. ...

If there are three bands and it appears as color infrared now, then you may have a different issue. The red band probably has been replaced by the infrared band, giving it the reddish appearance.  With that in mind, you do not have a red band now. I don't know if that specifically answers your question or how willing you are to experiment with re creating a red band, but my initial take is that the infrared band is the first band in that case.  Here are some common band combinations. ...

The only 3d portion of a 3d polygon is the edges.  Are you trying to harvest the inner section as well?  If so then I recommend converting the polygon to a Multipatch and then the surface to a multipatch as well. Then you could use the Intersect 3d.  Or if the 3d polygon is at a constant elevation, consider the Surface Volume tool or the Polygon Volume tool after you convert the raster to a TIN. ...

Match-AT can be used to add RPCs in after the fact.  I know you could use the ground control to georeference, but in terms of making them RPCs, not sure how that works. ... View more
