Jacob, I've been working with a similar system.  I've been downloading 1950's imagery of my area of interest from http://earthexplorer.usgs.gov and they are scanned images of original aerial frames.  I've been processing them with agisoft photoscan to make them a seamless orthophoto by cropping out the frame edges and registration marks.  Once they are properly aligned in photoscan I add markers as ground control points.  I'm using GCPs in the older imagery that match my current imagery.  Once properly orthorectified in photoscan, I export the imagery with a world file.  I can drop that into ArcGIS and it matches quite well. I expect that some of the issue may be that your imagery is true airphotography, and it has not been orthorectified yet.  Do you have some sample images that I could take a look at? Good luck, Paul ... View more

Thank you for the input.  I have started down the road with the following steps: 1) Create file .gdb for housing rasters, feature classes (for clipping) and each primary mosaic dataset. 2) Populate each file .gdb with the relevant raster dataset 3) Add raster to the mosaic dataset, build footprints, boundaries and overviews 3) Map out clipping polygon as feature class in the file .gdb 4) Apply raster clip function to the mosaic dataset 5) Add each primary mosaic dataset to a derivative mosaic dataset 6) Modify the MinPS and MaxPS values to show all imagery at all levels 7) Set defaults to order imagery by attribute, ZOrder 😎 Modify the ZOrder atrribute for each entry in the derivative mosaic dataset to correctly order the imagery 9) Export the whole thing as a tile package to be published on our ArcGIS Server Unfortunately, I think I'll be re-doing this process from scratch AGAIN... I'm exporting the tile package in the ArcGIS Server/Bing/Google WGS84 Web Mercator (Aux Sphere) format and I'm seeing the initial results and they look a little jagged and blocky. The original source imagery is NAD83 Alaska State Plane Zone 5 (feet) or NAD83 UTM 5N (meters) and it was added to the mosaic datasets in the original formats.  I've never been impressed when transforming imagery from this format to WGS84 WMAS on the fly.  I've learned by experience that the best thing to do it to transform the data into WGS84 WMAS at the beginning and then create the pyramids on the data in it's new projection.  I have been using "bilinear" for all my imagery pyramids. I'm doing all this work on my GIS workstation (a Dell 3600 workstation-class machine) w/ 32GB ram and it looks like the tile package export will take a few days for an extent about 60k+ sq. km. Any input is greatly appreciated, Paul VanDyke ... View more
