I’ve built a model from LiDAR data and CAD linework, both of which are projected in my local county system, and both of which display fine with perfect alignment. However – I decided to add some background imagery from the HEC-RAS web imagery options, and the ones that display at all show my project in the ocean off South America.
Obviously this is a projection problem – does RAS not reproject the imagery to match the project projection (that’s quite a sentence, but you follow me)? I’ve got local orthoimagery that I could probably reproject into the local projection in Arc but this seems like a significant problem – or maybe I’m just being dumb and missing something obvious.
