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

Once you create the slope raster, you can use the Reclassify tool to convert to a raster with the different slopes indicated or use the Extract by Attribute to select a certain selection.  Furthermore there are options with the CON statement to sort through the values.  So there are options. ...

With the Spatial Statistics tools, you can use the tool called 'Mean Center', does that help?  I am not sure how Zonal Statistics and the point density raster will help you determine the center.  The point density or kernel density  can create a raster and then focus the density, the highest point I suppose could be the center. ...

When you get around to testing it, I would recommend trying the Add Surface Information tool to determine the height of the point on the DEM and then compare it to the inherent z elevation. This should be the most direct test to determine if the point is indeed below the surface.  If it is, then you can consider whether the elevation is incorrect for the surface or if there are other issues.  If it is the same, then I would recommend creating the point at the desired height again that is above the surface. Let me know if you have questions when you get off the sideline. ... View more

So you have a series of points, collected at 5 cm increments and are looking to create a raster?  You could try a Spline to interpolate between the points, or if you have 3d Analyst you could create a TIN or Terrain to visualize it.  Each would create a continuous surface.  I suggested the Spline to rubbersheet and maintain the heights at the point.  Does that help?  It might also be interesting to convert the points to 3d and visualize in ArcScene to see if there are any issues with the data prior to interpolation. ...

Here is a blog that discusses how to adjust the background processing.  Can you provide any other information about the rasters you are trying to add?  Location ? Network or Local? Bit Depth? Number of bands? File Size?  When was the geodatabase created or does it happen with a new one? ... View more
