I'm trying to time-enable a series of images (NTFs) with 10.0 and having an issue being able to see the images as anything other than black. I've created individual source mosaics for each year of imagery, and build overviews and calc'd statistics, and these look great. I've then been able to combine them into another mosaic dataset (a derived mosaic) using the Table raster type... and additionally had to calc over the _MaxPS and _MinPS and _Cat values that aren't carried across; additionally, I'd created the Year field and set the Start/End Time Field in Properties. Using the time-slider, the foot prints and images turn on/off properly. But both this mosaic, and if I create a Reference Mosaic, the images are simply black. They become visible in ArcMap if I set Statistics to 'Current Display Extent', however, I don't want the user to have to do this in a viewer. Since the individual images have already had their statistics caculated (and had their overviews successfully generated) in their respective year mosaic before being loaded into the multiyear mosaic, I don't understand why they don't simply display.  Instead of loading into a mosaic as Table format, I have also tried loading them simply as the default type Raster, but this has the same issue. Has anyone else run into this/is there a solution, or perhaps a function I could use on the properties of the mosaic itself to calc statistics from the current extent? In the past I have gotten around this by adding the mosaic to arcmap setting the Statistics to 'Current Display Extent' and saving it as a .lyr file that I then published, but this severely impacted the service (took up to 10-20 seconds to display in a flex viewer). Any help would be appreciated! ... View more

Hello, I have a dataset that contains multipart features (most frequently for major highways, but also present through out much of the dataset).  The roads also have fields (short integer) for oneway and elevation (1,2,3).  Because end-end point connectivity is used to model when using elevation values, I can't get the network to function properly. I have applied the multipart to single part tool on the dataset which eliminates the multipart issue, however, this doesn't solve the end-end point problem. I have run feature to line tool to split the lines where roads intersect and then I can build the network with elevation value and it mostly works, however this splitting creates chaos in many areas, particularly around on/off ramp interchanges.  Aside from manually going in to these areas and re-attributing lines, is there another tool I could use? Has anyone else experienced issues with elevation values and multipart roads? Thanks in advance, Dave ... View more
