There are a multitude of reasons that the image service will not turn on.  For instance, what were the paths used in the creations, UNC or drive letter?  Does the Image Server Provider have permission to see the source rasters or overviews?  There are plenty of issues where it may lack permissions, especially if something changed on the server side.  Can you be more specific about the error?  If you are also that frustrated, I recommend creating a Support incident and then have an analyst look over the permissions with you. ...

Are you making the mosaic dataset 16 bit when you create it?  Also what is the output bit depth specified in the mosaic dataset?  Are you choosing to display them as 16 or as 8 bit unsigned?  I would recommend specifying the desired bit depth to start with and then consider what the output of the mosaic dataset is specified.  There may be issues encountered if the mosaic dataset if the bit depths are mismatched. ...

The variables are fields in the point file.  You have to add those fields to the point file.  Variables in a tool will not use them.  What type of field did you make them?  If you are still having issues with the point file if the variables are there, then please log a Support call and have someone take a look at your data with you. ...

When you are publishing a mosaic dataset you are getting that error?  Or you are publishing an iscdef through a mosaic dataset and receiving that error?  The image server authorization is not necessary when publishing a Mosaic Dataset.  However, I would consider all the permissions necessary when publishing through ArcGIS Server (source rasters, overviews & GDB).  If all of the permissions are correct, but you are still getting a license error, then I would confirm you have the Image Server license and the Image Server Extension license.  You need the extension to publish mosaic datasets and you need the standard Image Server license to publish iscdefs. ...

You will need to create the land cover raster. If you have a 3 band raster, you will need to perform either a supervised or unsupervised classification to create the raster.  Do this for both sets of data.  Once you create the rasters, you will need to compare the two rasters for the change analysis.  There are many examples on how to do this, including this link.  Also here is supervised classification. Here is the information about image classification. Also here is the information on LUCAT Tools. So there is a process, but it will require you to process the data, not just run a tool. ...

First it seems as if you are on the right path with looking at the memory and video card.  Be sure that you have the most up to date driver for your video card and try to not run too many other processes while in ArcScene.  To check your system, I recommend this tool.  Also the Terrain process, is not that complicated, unless you want to delve past some of the defaults for the pyramids.  Yes Breaklines can be used to create the Terrain, although mass points derived from LAS points are the usual input, with breaklines to augment it.  Also the Terrain once created will not display in ArcScene, but you should get better display in ArcMap.  The terrain's use of pyramids will improve the performance. ...

The gray is usually an indication that you cannot see the overviews (permissions)or they have not been built.  If you are having issues with seeing the SID at finer scales and the performance is slow, then consider stripping out the overviews in the SID when adding it to a mosaic dataset. This workflow will create more overviews during the Build Overview step, but will increase the performance.  If you are still having issues, I recommend creating a Support Incident and have an analyst take a look at your service with you. ...

The final step once you have performed the con statement and processed it back to an integer as described, would be to export the vat from the original raster and then join it back. ... View more

Based on your description, what you would need is lidar points. This could help with the collection of all of that data.  There would be multple returns and then you could then break them down into different surfaces to model all of the 3d features.  There are tools within ArcMap, but require 3d Analyst. Here is the help document on the terrain workflows.   Here is also more information on the multiple returns that I was discussing.   You have to probably obtain the full lidar dataset and then create surfaces based on the different returns, select the return value in the LAS to Multipoint tool and then you should be able to model all that you are looking for. ...

You could try changing the credentials of the Service Provider to run as the SOC and then be sure to be using UNC path instead of drive letters.  What does the ArcGIS Server Log say? ... View more

The purely grey symbol is usually indicative of the overview or source raster not being displayed.  Are the permissions correct for the Image Server or SOC account to access the raster or overview? ... View more

If you have a raster created from the lidar points then simply multiplying the raster by the conversion factor, 0.32808399.  You cannot modify the actual las points with the raster calculator just the raster created from them.  Alternatively, you can also just use the Times tool to create the same effect. ...

The angular results seem to be the result of missing data or extreme differences between the elevations.  You might consider trying to utilize the Conversion tools to convert to a raster and then resample to a finer resolution and then convert back to the TIN.  Also you may prefer the surface created by the Topo to Raster tool.  What you will need is more data to make it less angular.  How you prefer to get that data is another issue. ...

There are plenty of interpolation tools available, just understand how each will create the continuous surface.  Once the surface is created, you can use the Extract Values to Point or Add Surface Information tool to collect the information at those other points. ... View more

Bear in mind the uncompressed size of the raster(check the properties on the source tab in ArcMap), jp2s can be highly compressed and the size of the new raster may be larger than the original raster.  For an idea of what the expectations could be, convert the clipping polygon to a graphic, select the graphic, right click the raster and then Data > Export Data and when the dialogue opens up, selected graphic.  This will give you an idea of the size of the raster you are creating.   You are probably creating a raster much larger than the original. ...
