Buenas gente Al hilo de lo que dije en un anterior correo me gustaría informaros que estos días en la lista de correo de tagging se está debatiendo sobre las unclassified (un usuario planteaba que sus unclassified...tenían referencia, lo que va en contra de la misma definición de "no clasificada". Pues bien, al explicar la situación española en la que las categorías de OSM no encajan exactamente en la clasificación administrativa en algunos casos se han dado respuestas interesantes que para los que no seais de la lista de tagging os hago llegar:
Martin Koppenhoefer dieterdre...@gmail.com via openstreetmap.org in Germany and Italy (and probably some more places) the difference is between a road section without grade level intersections (and with ramps) vs not. Trunk is used in these areas for roads that are built to a standard similar to a motorway but not legally designated as motorway. It is not about access restrictions (there is the orthogonal motorroad=yes property for this). Kevin Kenny kevin.b.kenny+...@gmail.com via openstreetmap.org One issue is that we have the "UK English is the language of tagging" rule - which widely gets interpreted as "highway classification must be force-fit into the UK system." The US system presents a complex problem for this, since most highway classification is delegated to the states, and they all have their own local schemes. In many counties in the US, rural roads are unnamed and have only reference numbers. A farm road may be "County Road 2200N" (which is a different classification from, say, "County Highway 23", and typically shown only on small blade signs, not banner signs) or "State Farm and Market Road #2134". As I understand it, it would fit pretty closely with what "unclassified" roads - which are a formal classification in the UK! - are understood to be. Near where I live, numbered 'US', 'State' and many 'County' roads do NOT reflect the governing body - they are all managed by the state department of transportation. Historically, they had other structures, but responsibilities were reallocated. The 'US' highway numbers are coordinated with neighbouring states, but the administration is by the state. There are also numbered but (nearly) unsigned 'reference routes' also maintained by the state to 'State' highway standards. I say 'nearly' unsigned because they do often have inconspicuous chaining markers with their numbers. Rather than labeling the governing body, the 'US', 'State' and 'County' designations around here reflect the grade of importance, expected level of traffic and expected quality of maintenance. Given that the designation reflects relative importance rather than administrative jurisdiction, despite the labeling, I'm comfortable with having US, State, and County numbered roads be 'primary', 'secondary' and 'tertiary' - but in the places where the counties number virtually every road, there is a need for a tier below 'tertiary' - and 'unclassified' seems to be it; it's a working category that might otherwise be 'quaternary.' Salut i mapes yopaseopor PD: Me he mirado un poco el mapa de la "piel de toro" y he "pintado" como quedaría el mapa de la Red de Carreteras del Estado si se aplicara la propuesta que propuse. Y ya que estamos os sugiero que hagais lo propio, en breve podríamos tener un inventario o un mapa del trazado y categoría "real" que podrían tener las carreteras nacionales en nuestro país. Aquí os lo adjunto. https://i.imgur.com/SicS3Gu.jpg
