So by your description, it sounds like you are using version 10 and putting the output in the default.gdb.  Do you know if you have it set to overwrite existing results in the options?  Also it sounds as if you are also using the Results tab to re run the analysis. Is this correct?  If you are using this workflow, the results will be overwritten.  I would not think you would need to export them, but you will have to change the output name when you reuse the command via the Results window.  The output should reside in the default gdb.  So you will have to change the name each time. ...

Also can you check to see if the SOC account has permission to see the source rasters and overviews.  Also confirm that the server can see the rasters via the path used in the image service.  Are there other services running on that machine?  It also might be easier to have someone look over your shoulder, for that I recommend creating a Support call if the above solutions do not solve the issue. ...

So the original raster was in a file geodatabase, but works outside of a geodatabase?  Is it still reproducible or just in that particular ArcMap session? ... View more

Do you have the Image Server Extension?  Without the extension, you will not be able to publish the mosaic dataset in the mxd.  If you have the extension, be sure that you are using UNC paths and that the SOC has explicit permission to access the source rasters and overviews. ... View more

As a point of information, when draping polygons on top of surfaces, bear in mind that only the outline of the polygon will match the surface.  If the surface is particularly complex, there will be display errors.  If you are interested in having an object that will follow the surface, I recommend using the Interpolate Polygon to Multipatch.  This tool will create a multipatch that will mold to the surface and not poke through. ...

While the rolling the middle button or 'scroll' wheel will move the scene, I have always found right clicking and dragging mouse as more effective.  If you encounter the same issue, please try some of the other techniques listed here. ... View more

Aidan, Spaces are part of it, be sure to not include a special character or a leading name with a number.  You will need to make a name like 01-13.tif into t_01_13.tif.  While the error indicates only spaces, it could also mean invalid characters.  What are the names of the inputs you are using? ...

To echo what Eric said, you will have to make NoData values for the smaller raster to be 0.  So you must recopy the smaller raster and specify a spatial extent to match the larger raster. Then the Con statement to convert the NoData pixels to 0 can be used.  If there is a null value in the equation the product will be ignored.  So utilize the spatial extent of the largest raster when converting and then use the Con statement.  So the empty NoData areas will be converted to 0 and when the rasters are added you will only have the value of the larger raster. ...

The lookup tool will create a raster that has the value that you are looking for.  This concept of dot notation does not exist in python processing used in the Python Window, so you will have to create a new raster with the value desired and the processing can be done.   There is an enhancement request that exists to return that functionality.  Please log a support incident to add to that enhancement request. ...

It appears that you did not install the 'complete' version and may need to modify the install and then install that extension. Go to Control Panel < Add/Remove Programs and select ArcGIS Desktop.  When you select modify, you should see a menu that indicates what extensions are installed.  Select the option to install the extension and then try the previous procedure again. ...

The mosaic dataset just like an isdef does not import the raster data.  The source data for a mosaic dataset will remain in it's raw form as defined when you add the data to mosaic dataset.  The only data that a mosaic dataset will create is the overviews just like it would for an isdef.  So the issue you allude to of having to import the data is not correct.  There is also more control in the mosaic dataset to compress the overviews that it creates.  So in terms of data storage the mosaic dataset should be smaller.  Please take a look at the help documentation, which may answer your questions more thoroughly and discuss migrating to a mosaic dataset.  Don't be confused by the 'mosaic' in mosaic dataset. The only 'mosaicking' that it is doing is virtual in terms of creating the look, not importing the source rasters. ... View more

There are particular options to set the basic display of rasters, but for specific symbology you will have to create either a dummy file with all the possible values of all the rasters and then import the symbology.  If you are using 10, the properties options are here and then the options at 9.3.1 are here. If you have a set of classifed values for rasters and want to see your data displayed correctly create a dummy raster with values that will always be valid. Otherwise the symbology will have issues when applied to data that does not fall within the parameters.  So if you are looking to display change in percent, be sure your dummy raster has values that span far outside the percentages that will appear in your data.  So if your data generally fluctuates between -20 % and 60% be sure to make a dummy raster with max and min values that are at least -40 % and 80%. ...

I would continue with what Tim said and consider creating a series of multi point files in a geodatabase feature dataset with the Ascii to 3d Feature Class.  Once the files are in the feature Dataset, then you can create a terrain with them and then eventually convert the terrain to a raster if you so desire. Be sure to use the point file information tool, prior to running the two tools to obtain the point spacing.   There are a great series of blog posts discussing terrain workflows. ... View more

With the point file you have described, you have all the information necessary. Simply use the Add XY Coordinates tool to add the coordinates of each point.  Since you file has z values, the z value will also be added beside the X and Y coordinate. ... View more

You can use a toolbox. Its in Data Management Tools -> Raster -> Raster Processing -> Clip In here, you can tell it to clip to an irregularly shaped polygon. After you specify the shapefile to clip to as your Output Extent, then you also need to ensure that you put a checkmark beside the 'Use Input Features for Clipping Geometry' option. Is that what you needed? Don has the correct workflow.  Use the clip under Data Management > Raster > Raster Processing. If you do not specify the input geometry, you will receive the bounding extents of the polygon.  The output format of the raster is controlled by adding extensions. So .jpg for jpeg, .tif for tiff and so forth.  The only limit is the raster to be output must have the band combination/bit depth for the desired format.  Extract by Mask will also perform the clip, but Spatial Analyst is required. ...
