Apologies for the newbie / basic question, but it seems to be a fairly simple concept which I can't get to work properly, and I'd be really grateful for a pointer or two!
I have a load of different georeferenced raster tif maps loaded into ArcGIS (9.2). If I update the content of one of these maps in a program outside of GIS, (i.e. photoshop or equivalent,) I want the most up to date map to show in ArcMap the next time I open it. It's linking to the file in windows, so surely it's straightforward enough to refresh the link?
Right now, I don't know how to do this without either removing the map from the GIS file and re-adding it, or navigating to the file in windows and deleting the .aux and .rrd files, which is annoying. Surely there is a setting or an easy function I can use to do this? (Please say yes?!)
I would be much obliged if anyone could offer any advice.
P.S. I am just learning to GIS, and have no Python experience as yet, so please be gentle!
