They have augmented the 'Create Tin' tool to do all of the processing like the old toolbar button did. The old 'Create TIN' did not include data, but the new one does.  I agree the help needs to be updated for version 10 and I have indicated as much on the feedback for the page. If you see something like that I encourage using that feedback button.  It is a little button with a pencil on it.  As far as the TIN Chris mentioned, it appears that you are using your boundary as a Hard Clip rather than Soft clip. I would create the TIN again and this time, specify a soft clip and remove the height for that feature. ... View more

To perform the on-the-fly you will need the Image Server Extension. You can still go ahead and project the raster to the new coordinate system.  With the mosaic dataset, make it the Web Mercator projection and then be sure that the rasters added are in the previous coordinate system. If you do not like the projection that the mosaic dataset chooses, then specify a different transformation. You can specify the transformation in the mosaic dataset properties under the default tab.  Add the desired transformation there.  Otherwise you will have to reproject it and then either determine a polygon to clip out the NoData introduced during the projection or specify the background value and turn it off in the map document. ...

The natural next step is to create a Terrain from the different surfaces, with the Terrain the other steps can be performed to determine the volume of trees. Separating individual trees may prove difficult, but stand volume should work.  Polygon Volume, Surface Volume and can be used to determine the stand volume. ... View more

With the LAS to multipoint input you can create a separate surface for just the trees.  In the help documentation, there are codes for vegetation(3-5). If you LAS file has those codes then the surface can be built for the trees.  You can generate another terrain based on the bare earth and then compare them for the heights. ... View more

Be sure that you have authorized under the MIME settings in IIS to allow those raster types to be recognized.  It is discussed here.  Without those settings, the files will fail during the download. ... View more

I would consider the cell size of the raster and the rasterized version of the polygons.  For the zone to be recognized, the centroid of the raster needs to fall within the area identified as a zone.  If you are lacking the information, I would consider resampling the input raster to a finer spatial resolution or smaller cell size and it may help with the correct number of zones being returned. ...

Can you indicate what version of the software you are using?  There is a bug report for version 9.3.1, but it is indicated that it is fixed in version 10.  If you are using ArcGIS 10, please create a support incident to report this behavior. ... View more

The Ascii to Raster tool will work, you could add the Ascii file directly or if you decide to create points from the text file with an event layer, then you can utilize any of the interpolation tools to model the values between the the field points. ... View more

You mean the color model conversion function within Mosaic Datasets?  To complete the described process, you could use the mosaic dataset to create the look and then export it, or just utilize the mosaic dataset.  That would be the recommended way to create the color model change.  The mosaic dataset should be fairly fast, if your script is causing performance problems. ...

3d Analyst would be the toolset to accomplish it. However the 3d buffer is not currently possible.  You can interpolate the streamline to match the elevation of the terrain.  The buffer may be problematic as you really want the 3d distance rather than the straight line distance.  The out of the box tool on buffering the 3d line will simply create the polygon.  With the normal buffering for the horizontal distance and then extrude the polygon up or down, you could create a 3 dimensional buffer similar to here to create your multipatch.  I am not sure how to create the variable buffer based on the slope distance. ...

There are steps for a complete uninstall that Esri Support can walk you through rather than just trying uninstall the software.  Depending on the situation, there can be 3rd party extensions that can cause the issues you are describing as well as the normal Windows related problems that can seem to randomly occur.  I would recommend contacting Support and describe the problem.  They should be able to determine if it is in fact necessary to perform the complete uninstall/reinstall or they could test it to see if it is workflow/data related. ...

Have you tried adding the Statistics function to the clipped area?  You may have to create referenced mosaic datasets and then perform these two functions (Clip and Statistics) to obtain the data you are desiring.  I do not think the On-the-Fly clip you are describing will create the desired results. ...

I would consider using the LAS to Multipoint tool to create a multipoint feature class.  Also you may consider specifying only the Bare Earth points to eliminate some of the excess data. The 2 gig limit imposed on shapefiles would not happen and the file maybe handled easier.  Perhaps the CLIP in ArcMap would work easier if it was a Multipoint.  The process you are describing is very memory intensive and I recommend shutting down all other applications prior to running the process. ...

Due to the change to GDAL from the previous raster utilities, the manner in which the georeferencing information is being read changed.  When this issue was discovered, there were service packs created to solve the issue.  Tifs at previous versions should display with the latest service packs. If they do not please log a Support incident to test and then add to the existing bug or create a new one.  I do recommend if you have updated the Georeferencing at 10 no service packs that the resulting raster will be problematic in previous versions of ArcMap and also with 10 installations with the Service Packs.  With the Service Pack installed the tifs georeferenced at 9.3.1 should be seen correctly and any raster georeferenced at 10 SP 2 should be seen correctly.  If in doubt, rectify the raster rather than update the georeferencing.  Please log a support call to be added to the specific bug reports or report new problems with those rasters you created. ...

If you can see the overviews, but not the source rasters then it is the permission to see the source raster that is the problem. Check the path used in the ISDEF to access the source rasters.  Be sure that the Service Provider/SOC has access to that data.  You may not have added the provider and SOC accounts to that folder.  If you the Branch office cannot help, then I recommend creating a Support Incident. ...
