Is the lidar imported into a multipoint feature class?  If so then the straight conversion would have to include converting the multipoint features into individual points. Once the individual points are created then perhaps the values could be read like this.  I am wondering if you have used the RGB symbology of the LAS files within ArcMap through a LAS Dataset and then try to export that into a raster. You can also export the LAS Dataset with the LAS Dataset to Raster tool and select RGB.  This might actually be more time efficient, since depending on the LAS file, you may be creating millions of points from the multipoint feature class.  I have never tried this workflow, but perhaps this may get you closer to your desired output. ...

You might get a better result by making the Raster Resolution of the raster you are draping match the original raster resolution.  By default, the raster resolution will be more coarse than the original to save processing time.  However, the best option may be to use the bare earth DEM and then add 3d Symbology or multipatches of the trees to get the best effect. ...

This blog can help expose the fields with the BLOB characterization within them. I am more familiar with the Intensity field, but I suppose within your data that information can also be exposed.  Have you tried looking at the fields in ArcCatalog? ... View more

Have you tried the Raster to Point tool?  That may work better than that workflow from 9.0. ... View more

I would recommend trying to look at the added rasters to be sure none of them are corrupt or somehow different(ie undefined projection).  If they are fine, then try to create a mosaic dataset in a file geodatabase and add the data that you just added.  If that succeeds then I would call into create a Support incident as something is not correct.  Usually that error would appear when there is an issue with the extent of the added rasters.  In this case, it may be the extent is not correct, corrupt or the projection it is in will not fit in the coordinate system of the existing mosaic dataset. You can also try to add the new imagery a little at a time and see if you can determine which raster may be causing the issue. ... View more

Which version of ArcMap are you using?  The rft should work for the information provided.  What is the published service doing? ... View more

Consider using the skip factor for the long processing.  It is outlined here, but the recommendation is to identify a reasonable skip factor value is to divide the number of columns by 1,000 and use the quotient (integer) as the skip factor. ... View more

I think I am following the description.  You have 4 individual rasters with each representing a particular band. It seems you have processed the bands to remove the NoData and now want to combine them?  If that is the case, then use the Composite Bands tool. It will create a single raster with 4 bands.  Hopefully the NoData issue will be resolved by your attempt, but at worse will need to be handled at this point. ... View more

Image classification can be accomplished through supervised or unsupervised.  For more object-oriented classification, you may be interested in eCognition or Feature Analyst. ... View more

You will have to emulate that account on the remote server if you are only able to access it via that account. So you are on the right track. Whatever account you can see the source rasters from on your local machine, must also be emulated on the server. Usually if you are publishing the service, it is important to keep the SOC account emulated on systems running 10.0 and under and emulating the ArcGIS Server account is required. The account must be added explicitly, simply making it open to 'Everyone' usually doesn't suffice. Per the help, during the setup you'll be asked to provide one account that will access your GIS resources and data and run the ArcGIS Server service. This account is the ArcGIS Server account. At 10.1, there is no postinstallation to complete, and there are no SOM, SOC, or ArcGIS web services accounts to configure. ... View more

What you will need to do is create a raster function template from your symbology and then apply to the published image service. This should preserve what you are doing and allow the image service to be classified as desired when added to ArcMap or blended into a web map.  Configuring an image service to use a raster function template You add the .rft.xml files to the image service when you configure the parameters for it before publishing. Steps:    If the image service is published and running, stop it.     Access the image service properties.     From the left menu of the Service Editor dialog box, click Function.     Click the Manage button to open the Manage Raster Function Templates dialog box.     Add one or more .rft.xml files to the list.     Optionally, choose a raster function template to apply by default by selecting it in the Default drop-down menu.     Click OK to close the dialog boxes.     Publish the image service. ...

There is an extension that should be used to view the rasters in ArcMap.  Here is the install guide. From the website, it appears that you must contact them to download it.  Best of luck. ... View more

Glad that worked out.  As a former Support Analyst, I have used this technique before.  Since tifs can be created from a multitude of programs and there is a standard published, there are still instances that the best technique is to save the raster over in ArcMap and then see if it displays better.  Also bilinear pyramids are always seem to do better with 1 bit rasters. ...

If the rasters are one bit, then the issue is probably with the conversion of one bit to the copy or the pyramids that are 8 bit.  You can also look at the pyramids and the resampling method. ... View more

There is no 'Image Server' stand alone anymore.  So if they asked you for an image service, then you will need the Image Server Extension.  At 9.2 - 10, there was a completely different setup to perform and a toolbar.  Now the image server extension grants the ability to publish mosaic datasets and mosaic datasets can be created via geoprocessing tools in ArcToolbox. There is no need for a separate toolbar nor different install. ... View more
