Re: [Talk-it] Mappa per Garmin del Piemonte da dati CTRN e OSM
Hi group! I have published the development package for the CTRN-OSM-GPS map. This package contains all scripts and styles I wrote, plus some helpful bits like QGIS style files for the CTRN, and map icons. The package can be looked at and downloaded from this mercurial repository at bitbucket: https://bitbucket.org/kfj/ctrn-osm-gps-dev My method of converting ESRI shapefiles with ogr2osm into an intermediate representation in OSM format and then directly into a garmin map with mkgmap may interest other map-makers out there - so even if you're not from the Piedmont you may find the package interesting. It has taken me quite a while to figure out this technique, and it can be used for any ESRI shapefile (plus other OGR-compatible data sources), uses free tools only and is entirely script-driven. The use of free tools was especially important to me - this sector has a lot of software which isn't free, or has strings attached, or the free version is crippleware... I'm sure you know what I'm talking about. And to automate the whole conversion process, GUI-driven tools aren't the best choice, so doing everything with scripts is a nice solution :) I have previously been critisized for my licensing of the CTRN-OSM-GPS map (it's CC-BY-NC-SA), even though I feel it's an appropriate license and suitable for my combined work from several sources - see http://lists.openstreetmap.org/pipermail/talk-it/2012-November/031707.html I hope my publication shows that I do not intend to keep others from emulating my work and that I want to bring forward the use of open data. Yet again, please forgive me for posting in english; if anyone feels like translating this posting, please do so, and thanks in advance!

Is very unconfortable have to activate area by area, it should be better if there was only a big area instead of many little areas Ora capisco quello che vuoi dire. Questo perché la CTRN è organizzata in piccole sezioni rettangolari, circa un migliaio di loro, e per ogni sezione ci sono diversi shapefile. Ho combinato le corrispondenti shapefile di 16 sezioni adiacenti (come 66.019.000-66.019.150) nelle piastrelle più grandi (66.019.000), perché altrimenti ci sono troppi, ma naturalmente ci sono ancora un sacco di piastrelle. Potete dare un'occhiata al layout della mappa originale di dati.piemonte.it. Non so se è possibile mettere in valigia tutto in grandi aree (pensiamo come siamo volutamente diviso i dati OSM in sezioni gestibili invece di fare uno grande -. Che è l'6.324.000 [1-4] img nella mia mappa), ma cercherò di scoprire quando trovo il tempo. Che cosa si può fare per ora è questo: dividere il gmapsupp.img (con gmt) scegliere solo le sezioni che si usa unirsi a quelli in un piccolo gmapsupp.img Poi si dovrà solo quelle aree che avete messo in posto tutto il Piemonte e la scelta diventa molto più facile. *** english original Now I see what you mean. This is because the CTRN is organized in small rectangular sections, roughly a thousand of them, and for every section there are several shapefiles. I've combined the corresponding shapefiles of 16 adjoining sections (like 66019000 - 66019150) into larger tiles (66019000) because otherwise there are too many, but of course there are still a lot of tiles. You can have a look at the layout of the original map at dati.piemonte.it. I don't know if it's feasible to pack everything into large areas (think how we deliberately split the osm data into manageable sections instead of just making one big one - that's the 6324000[1-4].img in my map), but I'll try and find out when I find the time. What you can do for now is this: split the gmapsupp.img (with gmt) pick only the sections you use join those into a small gmapsupp.img Then you will only have those areas which you have put in instead the whole of the Piedmont and the selection becomes much easier.

La mappa sembra bellissima, peccato però che non ci sono le linee srtm. Oggi vado a fare un giro in bici e la provo. Ho tradotto la mia risposta con Google e incluso il testo inglese di sotto nel caso la traduzione non ha senso: Se non riesci a vedere le curve di livello sulla vostra unità GPS, c'è un problema tecnico. Si prega di scrivere quale unità GPS si sta utilizzando. Sul mio Etrex Vista HCx, le linee di contorno sono ben visibili - fino a un passo ingrandimento ragionevole. Le curve di livello sulla mia mappa sono in realtà molto meglio di SRTM. Essi sono presi direttamente dalla CTRN. I contorni minori sono 10m. Il DEM sottostante ha una risoluzione 10m, anche se alcune zone sono interpolati. Ho scelto di non generare linee di contorno del DEM (che è stato anche messo in linea per il riutilizzo da parte delle autorità piemontesi), ma di utilizzare le linee di contorno CTRN readymade, al fine di rimanere il più vicino possibile all'originale (e salvare il lavoro ;-). Il superiore disponibile DEM dalla CTRN era la mia motivazione principale per farne una mappa GPS. La seconda ragione principale era la precisione dei fiumi e dei torrenti, che OSM non può sperare di raggiungere in tempi brevi - a meno che non vengono importati i dati CTRN, che è una mossa sosterrei, e sostenendo che la mossa era un altro motivo per fare la mappa: a mostrano come la topografia precisa combinata con up-to-date dati OSM può fare davvero un buon programma. Buona pedalata ;-) * english original: If you can't see contour lines on your GPS unit, there is a technical problem. Please write which GPS unit you're using. On my etrex vista hcx, the contour lines are well visible - up to a reasonable magnification step. The contour lines on my map are actually much better than SRTM. They are taken directly from the CTRN. The minor contours are 10m. The underlying DEM has 10m resolution, though some areas are interpolated. I have chosen not to generate contour lines from the DEM (which has also been put online for reuse by the piemontese authorities) but to use the readymade CTRN contour lines, in order to stay as close to the original as possible (and save work ;-). The superior DEM available from the CTRN was my main motivation for making it into a GPS map. The second major reason was the precision of the rivers and streams, which OSM cannot hope to achieve anytime soon - unless the CTRN data are imported, which is a move I would support, and supporting that move was another reason to make the map: to show how precise topography combined with up-to-date OSM data can make a really good map.

Avevo paura che c'era un problema con la mappa! Very well. I had feared there was a problem with the map! Ho trovato molti dati che su osm non ci sono, e questo fa piacere Si. La CTRN ha un sacco di dettagli, ma non è stato aggiornato da un po 'e ci sono vecchie caratteristiche nella mappa di cose che non ci sono più, mentre è mancante cose nuove. La mappa è pensato principalmente per gli escursionisti, e dovrebbe essere utile per mapper pure. La CTRN non è molto buono per sentieri, ma un sacco di escursionisti ora contribuiscono a OSM, così CTRN + OSM sembra una buona combinazione. Indeed. The CTRN has a lot of detail, but it has not been updated in a while and there are old features in the map of things which are no longer there, while it's missing new things. The map is mainly meant for walkers, and it should be useful for mappers as well. The CTRN isn't very good for footpaths, but a lot of walkers now contribute to OSM, so CTRN+OSM seems like a good combination. Trovo difficoltoso attivare e disattivare la mappa ad aree, come posso modificare la mappa in modo che quando attivo i poligoni siano attivi per tutta la mappa e non solo per l'area scelta, in modo da avere meno voci nel menù da attivare una ad una. Questo bit non capisco - probabilmente si utilizza caratteristiche del C60 che il mio etrex non ha. Per quanto riguarda la modifica della mappa va, è realizzato con strumenti gratuiti standard (ogr2osm, mkgmap) con i file di stile e simboli che ho disegnato (dove non sta usando simboli standard). Sarò felice di condividere il mio flusso di lavoro, in modo da poter modificare a vostro gusto. This bit I don't understand - probably you are using features of the C60 which my etrex does not have. As far as modifying the map goes, it is made with standard free tools (ogr2osm, mkgmap) with style files and symbols which I have designed (where it's not using standard symbols). I'll happily share my workflow, so you can modify it to your taste. Se ti serve spazio per la mappa sul mio sito ne ho, non sarebbe un problema ospitarla. Relativo all'istituzione della mappa, la ringrazio molto per l'offerta. Mi metterò in contatto con voi fuori lista in modo da poter discutere gli aspetti tecnici. Concerning the hosting of the map, thank you very much for the offer. I'll get in touch with you off-list so we can discuss the technicalities. ** BAD ENGLISH *** I use the maps on a gps60csx, the contour are shown, I had not seen the first time, the map function properly. I found a lot of in this map that arent in OSM, i am very happy to use a well detailed map. I have difficult when i turn on and off the map features, every feature is divided by area, and i have to switch on and off many voices How can I change the map so that when active a feature this is active for all map map and not just for the chosen area, in order to have fewer items in the menu to activate one by one.

[Talk-it] GPS map of Piemonte from CTRN and OSM data
Dear members of the ML! Since I'm new on the list, let me introduce myself first: my name is Kay, I've been contributing to OSM for some time now as user kfj: http://www.openstreetmap.org/user/kfj I am german, but I spend much time in the Piedmont, and this is where I do my mapping. My italian is clumsy, so I write in english. I have created a GPS vector map of the Piedmont. The map is intended mainly for hiking and similar outdoor activities; I have also found it useful for mapping. It is a synopsis of the CTRN vettoriale 1:10.000 (1991-2005) and OSM data. It's in garmin image format and runs on my etrex vista hcx, but it should also run on other GPS units using the same data format. The map is currently at beta stage, so I have decided to offer it to a limited audience for evaluation. While I have processed the whole area covered by the CTRN, I have also made a smaller map of just the northern tip of the piemontese territory. This smaller section may serve to establish that the map will function on your side - the complete map weighs in at some 300MB, so the amount of traffic needed just to find out it doesn't work for you after all would be a waste of resources. You can find the sample map here: http://ubuntuone.com/70ApLzr7jlglmg8BVl9ldN and the complete map here: http://ubuntuone.com/6wok0LEk30quYb3ontLs8R These files are zip-compressed folders containing the map (in garmin.img format; I trust you know what to do with such a file) plus a README and some files picked from the CTRN data. If you just want to know more about the technicalities of the map, you can download the README file separately from here: http://ubuntuone.com/0An1JJJwgsrqtm6YleYnBy I release the maps under CC-BY-NC-SA license, see http://creativecommons.org/licenses/by-nc-sa/3.0/ I'd appreciate comments - especially concerning the usability on various GPS devices and also of grave problems with the maps, but I can't promise to fix reported bugs as my resources are limited. The technical details can be found in the README accompanying the map. So far I haven't published my own tool chain - a set of shell scripts and the various styles and TYP file. I intend to do so eventually, to allow interested parties to emulate and improve my work, but I'd prefer to have some feedback first. This mail was initially sent to talk-it-piemonte, where it was suggested that it should be posted to talk-it as well. I've had the first reports coming in already, and one piece of good news is that the map runs on the c62 as well. A word of caution: if you install the full map after the sample map, you'll have to delete the sample. Both together won't work, I assume this is because I used the same product ID for both. On the etrex which can't handle multiple maps this isn't an issue. Eventually the sample map will be taken offline. Kay F.

Re: [Talk-it] GPS map of Piemonte from CTRN and OSM data
to share my work (rather than just enjoying it myself), and to do this in a legally proper fashion, I had to spend days researching and corresponding and creating my own styles (rather than using ready-made ones, which would have introduced yet more licensing issues) to satisfy all the license requirements. If my understanding of the legal matters is wrong, please point out specifically where you see conflicts. The ODBL should have made my work simpler, and when I read through it carefully I found that there are some subtle changes in the treatment of derived works (compared to the previous license) which give me more freedom in licensing the final product than the previous license. Ps: next friday and saturday there is the national italian conference about openstreetmap in Torino :) You are welcome also with a presentation of your job Thank you for the invitation! But I won't be able to attend, as I'm not in Italy at all. With a bit of luck, my map will have been used by some of the community and they may discuss it and spread the word even if I'm not there.
