Can I project images or grids real-time in Arcview 3.x?
ArcView 3.x cannot project images on-the-fly, it can only project vector (feature) files on-the-fly. ArcView, ArcEditor, and ArcInfo version 8.x and 9.x can project rasters on-the-fly. To project you images to different projection you will need an application like ISIS, ENVI, Arc/Info, or other image processing package. Although if you own Spatial Analyst, Kenneth R. McVay, has written an extension called Grid Projector that might be useful. Jeff Jenness has also generated a Grid Projector extension (and many other great tools).
