Yeah, I would just label them as it is signed. No one cares about octane rating systems. They care about what it says in the car owner manual and where they can get gas that matches that number. It is implied that the numbers follow whatever rating system is prescribed by law in the country the gas station is in. Since all cars sold within a given country will follow the same rating system as all the gas stations in that country, the rating systems are a non-issue. So just tag it as fuel:octane_87, fuel:octane_89, etc. That sounds logical. I probably won't end up tagging them a whole lot since virtually all gas stations (tagged amenity=fuel) currently sell 3 variations of unleaded gasoline. Not Sure about the kerosene. fuel:kerosene=yes would seem logical but I'm not sure what the non-taxable use has to do with things. Looks like there's a handful of people using fuel:kerosone=yes, so I'll go with that. As far as non-taxable use, I believe it is common practice in the US and elsewhere to put dye in diesel fuel and kerosene to mark the fuel for non-taxable use. Taxable use is basically using it to power a vehicle that drives on the public roads. Non-taxable use is things like kerosene lamps or heaters. Farm tractors might also use dyed diesel fuel. Basically, if it has dye in it, it is sold cheaper than if it doesn't (less tax). While we're on the topic of fuel types... I've been wondering about diesel. The JOSM preset has 3 different diesel checkboxes. One is for bio diesel which is fine. But is there any chemical difference between Diesel and Diesel for Heavy Goods Vehicles? Or is this tag just clarifying the physical characteristics of the pump? (enough space and clearance for a big rig to maneuver to the pump) Yes, it is for the physical characteristics of the pump, but it has more to do with the nozzle. Fuel nozzles that are used on big trucks don't necessarily fit inside diesel cars. Big trucks have larger fuel tanks, so they need a bigger nozzle to help them fill up faster.

I believe that this has to do with road-use taxes. Part of the price you pay for gasoline is actually a tax that goes into special road construction and repair funds. The kerosene for sale at the station is probably for non-vehicular uses (generators and lamps perhaps) and thus does not include the road-use tax. While we're on the topic of fuel types...

(enough space and clearance for a big rig to maneuver to the pump) Or is this tag for something else entirely? Possibly, I know around here there are stations that sell diesel at pumps side-by-side with the gasoline pumps - you'd never get a large tractor-trailer in there to fuel up. There are also a few stations (aside from the large truck stops on the Interstate) that have separate stations for tractor-trailers to fuel up. They actually have pumps on both sides of the vehicle that are connected to one payment system so that tanks on both sides of the vehicle can be fueled simultaneously. -- Jeff Ollie ___ Talk-us mailing list Talk-us@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-us
[Talk-us] NHD data conversion
I was watching with anticipation the conversation about pre-converting NHD data for the whole US, but it seems to have died down since June. I think I'm the target audience for this effort (I'm willing to put in time merging the data in carefully, but I'm not conversant in the command-line tools to prepare it) so I'm curious what the status is. -- Ben ___ Talk-us mailing list Talk-us@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-us
