Reproject imagery to match ESRI coordinate system and basemap tiling scheme
This may be more of an ESRI question but I've been trying in vain to reproject our ortho imagery so I can use it with some ESRI basemaps in a site. Does anyone who has successfully done this have any tips?

When I had this issue rather than reproject the imagery to a new dataset I simply added some ESRI data to ArcMap in order to set the coordinate system and then added my own imagery so it reprojectyed on the fly. I then removed the ESRI data and generated my cache from it using the ESRI tile scheme settings. I'm not sure how dynamic imagery would perform, but I have no isues with my cache. 0 -
That's a great idea! I'll give that a try. 0 -
Whenever we publish imagery through an image service using ArcCatalog, it defaults to WGS84. 0 -
We follow the same procedure as Lee to create caches of our imagery in multiple coordinate systems. Luckily, our city isn't a huge entity so our caches aren't prohibitively huge to follow this method. 0 -
I would suggest creating a mosaic dataset with the web mercator projection and add your imagery to it. You can cache and serve this mosaic dataset out as an image service or even as a tile package(TPK). You can do the same for any other projection and thereby avoid reprojecting the raw raster data.
Web Mercator is not a useful projection for us and so we cache all our own basemaps with a custom tiling scheme based on state plane.0
