Brian, I'm hoping that you are the one who posted me a message last week. I've been on holiday and read a message quickly without downloading and now the original has disappeared. I think someone is missing an opportunity. I bought some Digital Contour Data from the Ordnance Survey to plot contour templates for a physical model. The Digital Contour Data worked fine but I thought it would be nice to have a computer model as well. I discovered Vistapro and was astonished that such powerful software was available at the price ( well done that man John Hinckley Although the contour data is not ideal, I have managed to convert it to DEM format with some very nice results. As far as prices go, my recollection is that the initial price for a 20km squae was 30 pounds. I haven't a clue about how the OS would n for DEM converted distribution etc. but the data didn't seem expensive to me. It would seem crazy the OS should pass up the opportunity for a mass market for their data. VRLI should also be aware that the UK is one of the few (only?) countries that has the data to provide DEMs at this moment for it total land area. Unfortunately, I am pretty sure that even without reading the OS licence small print I cannot share any of my converted DEMS with anyone else (sob!). I hope this long message is of interest to someone if you are not the Brian in question. Paul

Paul: 20 km's cover a bit larger area than the USGS quads (about 14km), and the price is reasonable for the serious enthusiast, but for a typical 'data set' that VRLI sells (about 20 USGS quads) for about $35, it would cost on the order of $600 (don't know exact conversion, but $1.6/pound is reasonably close) for a similar set of OS data. I do remember that VRLI could not re-sell without paying the fee for each copy sold. VRLI gets complaints at $35/set, I can imagine the screams they'd hear at $600. <grin> It's definitely something that serious individuals should look into, but it is not practical for VRLI to convert and re-sell the data.

Thanks for the info Paul. Presumably you could share your method of obtaining the results for others crazy enough to want to do it? Maybe Clint would post it in the library? How about polling the uk members to see if there is enough strngth of opinion to form a pressure group to convince HMG that this data should be in the public domain as is the case with USGS data ? I'd have no objection to paying a reasonable handling fee, but most of the surveys were done with taxpayer's money _before_ the OS was privatised! Maybe we could put an item in the VRLI newsletters (amiga _and_ PC) how about it Clint? Brian PS (HMG = Her Majesty's Government)

Brian: I'll be glad to post information on how to convert OS files if I ever get ahold of it. <grin> I will pass along the request for an item in the newsletter to VRLI. I am just a part time contractor to VRLI for tech support here on CIS, so I can't make any decisions as to what they include, but I will pass it along to those in charge. Clint <VRLI>
