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

The checkerboard appears usually when you have either not generated overviews or lost access to the overviews or source rasters.  What does it look like in ArcMap when you look at the raster prior to exporting? ... View more

The raster must be a classified into two colors, per the help on ArcScan.  You cannot use it to edit a 3 band RGB raster if that is the color one you have. ... View more

If you need a SID then refer to GeoExpress from Lizard Tech directly.  You could output to a Tiff with YcbCR compression have some of the compression. ... View more

Raster Painting would work if you had two values as you would for ArcScan, but since you sound like that is not what you want, you might consider the workflow for how to use the Con Statement to alter the value for just those select ones. ... View more
