Transterritorial - The mac portion may be the problem depending on the path and also whether that drive can be accessible from the MAC side as well. The most stable version of ArcGIS on MAC is still when it is loaded via Bootcamp. I think that for the rest, if these DEMs are Esri GRIDs you should consider the path to the raster.  I have seen issues with spaces, leading number file names and special characters.  If the path to your raster contains these, then I would recommend changing the path or moving the rasters.  In terms of spaces in the path, I have seen issues on certain systems and not other systems on the same network.  Personally, I have added up to 14 spaces in the folder path for my test machine and not had an issue.  However, I have also see a space being the cause of a problem for a user.  So consider the path wisely. If you are still having issues, then I recommend opening a Support Incident and we can take a look at what may be causing the issue. ... View more

I would process the attempts in ArcMap, since ArcScene utilized video card memory, once you are out of it - crashes.  You can always run the tool in ArcMap and view results in ArcScene. ... View more

You said that your TINs have the same extent, I would consider moving one just inside or just outside the spatial extent or utilize the Extrude between and keep the TINs the same extent, but make the polygon being used just inside.  I have discussed this workflow before in this blog to create a block diagram. ...

This can be a tricky problem when programs export their data to a format that is recognized in ArcMap as something else.  I encourage you to take a look at the supported raster information. If your raster extension appears there, but the description is different then be prepared for issues.  Beside the .dem (USGS) format another usual issue is the .map format, as ArcGIS supports PCRaster's version not Mapinfo's .map. ...

If your original data was in UTM and you projected the data to a new coordinate system, then did you change datums?  If so did you specify a transformation in the map document?  You may need a transformation specified for the data to line up correctly. Please refer to this blog which discusses how to determine the proper transformation. ... View more

Are you right clicking and select 'Identify'?  It works fine that way for me?  Or are you trying to just use the identify tool?  When I right click the profile graph, select Identify then I see cross hairs on the location on the line. ... View more

Why not interpolate the line created with the horizontal position to match the existing DEM?  That would avoid the snapping issue and trying to choose the correct one.  The interpolated vertical would be more dependent on the horizontal accuracy provided, but should avoid the issue of trying to choose the correct vertical line to choose. ...

So you are digitizing the lines by snapping between known control points?  Is that correct?  Well, I would recommend the break lines for the crown of the road, edges, and the curb and gutter to create a better surface for contouring.  I am not sure if I would just start creating the lines by snapping any control points together.  To force the surface to model that as a line, be sure to specify the input as a hard line when creating the TIN or editing it. ...

So you can see the source rasters correctly when creating the mosaic dataset and generating the overviews, but cannot when you attempt to publish them?  Is that correct?  Have you registered the 'data store' with ArcGIS Server?  Also how are you accessing the data?  A good test is to use the path used when creating the mosaic dataset in Windows Explorer from the Server machine.  If that machine cannot recognize that path, then you will have to modify the path so that the machine can see it.  It has been my experience that different networks and operating systems are more tolerant of '$' shares and paths with spaces and characters. ...

Generally speaking, the RPC or rational polynomial coefficients are created by the sensor, usually a satellite.  In most cases, the RPCs are included with satellite imagery, as mentioned here.  In terms of ortho rectifying your UAV data, then if the RPCs were not generated in the process then you must find a way to create check points based on surveyed ground control points that should have ideally been collected prior to flying the project.  There are other software packages that can help you orthorectify with manually added checkpoints, like ENVI. ...

In REST, you can use the Identify operation to query an individual location and return a value.  The identify operation is performed on an image service resource. It identifies the content of an image service for a given location and a given mosaic rule. The location can be a point or a polygon. The identify operation is supported by all kinds of image services (Mosaic Datasets, Raster Datasets). The result of this operation includes the pixel value of the mosaic for a given mosaic rule, a resolution (pixel size), and a set of catalog items that overlap the given geometry. The single pixel value is that of the mosaic at the centroid of the specified location. If there are multiple rasters overlapping the location, the visibility of a raster is determined by the order of the rasters defined in the mosaic rule. It also contains a set of catalog items that overlap the given geometry. The catalog items are ordered based on the mosaic rule. A list of catalog item visibilities gives the percentage contribution of the item to overall mosaic. Or Query on a bounding box of coordinates, per the help The query operation is performed on an image service resource. It queries the raster catalog by applying the filter specified by the user. The result of this operation is either a set of features in the raster catalog or an array of raster ids (if returnIdsOnly is set to true). Also there are geoprocessing tools that can also be used for specific point locations like, Sample, Extract Values to Point and Add Surface Information. ... View more

Why not take the xyz data, create points via an XY Event Layer in WGS 1984. Then project the points to UTM and then either interpolate a raster or convert it to a raster there with the cell size of 5 meters. The point to raster or feature to raster tool will not interpolate between the gaps, if you have any, but otherwise should work. ... View more
