I think Jason has managed to summarise very well what I was driving at. The lack of standards has inhibited and will inhibit future use of national projects such as historic landscapes and urban surveys. Many SMRs are now grappling with how best to depict the historic environment on CAD and GIS, for polygons and lines, and also points. There is also the issue of whether it is possible to define standard symbol sets for heritage features, especially as the OS seem less keen on showing archaeological sites on their digital maps. These are clearly areas for the heritage sector to address and there don't seem to be any other contendors than FISH. English Heritage started a spatial standards working party some time ago but that soon fizzled out. As Jason says, it is time something was done while the problem is relatively small, but the problem is growing fast.
