In February I boldy announced my plan to map my hometown during the year, and I think it is time to look back at how everything worked out. First off: I did not get to complete my plans, nevertheless there were many changes to Zirl and the surrounding area that improved the map a lot:

• Most of the buildings in Zirl have been drawn from aerial images. Some of them by me, but many of them also by other friendly helpers (thanks!)
• I did some ground sourveys as well, which allowed me to correct the shape of buildings if necessary, add address tags and some other information like points of interest. I only managed to do this for a couple of streets, but it has clearly shown me that drawing buildings from an aerial images is not enough.
• In April user mariusmueller added address tags from a goverment database called Tiris. At first I was not sure if this was ok copyright-wise, but since OpenStreetMap.org has now added “Land Tirol” to it’s copyright page, everything should be ok. Thanks mariuesmueller for your help!

So what is left to do? Buildings and addresses have been added, but a ground survey to verify building shape, addresses, etc. and to add other points of interest (shops, fire hydrants, parking spaces, …) is still needed. So my plan for 2013 is to do just that.

Vor ein paar Monaten habe ich den Plan gefasst, meine Heimatgemeinde zu erfassen. Ein großer Teil der Häuser ist bereits anhand von Luftbildern eingezeichnet. Das Mappen von Hausnummern gestaltete sich jedoch als langsamer und aufwändiger Prozess, unter anderem auch weil die Gemeinde ohne Vorausschau Hausnummern vergeben hat, so dass man sich jetzt mit Krücken wie 1a, 1b oder gar ungeordneten Hausnummern helfen muss.

Umso mehr hat es mich gefreut (und überrascht), als plötzlich sämtliche Hausnummern durch einen fleißigen Mapper eigetragen wurden, anscheinend anhand von Tiris-Daten. Ich kenne mich bei rechtlichen Angelegenheiten leider nicht aus, daher meine Frage: Ist es erlaubt, Hausnummern und deren Position von Tiris zu übernehmen? Im Wiki konnte ich leider dazu nichts finden.

Falls ja, wäre das wunderbar, denn so könnte man den langweiligsten Teil (das Erfassen von Adressen) auslassen und gleich zu den spannenden Teilen wie Häuser zeichnen, POIs eintragen, etc. springen.

My goal for 2012 is to map my home town, Zirl. Luckily many streets are already done (though the access attributes are often missing), but I want to go one step further and have every house with address and points of interest (shops, doctors, ...) mapped.

I have created a plan for when I want to do what. During the month of February I will use the currently drawn streets and my GPS tracks to align Bing maps and then use that to draw every house. I will just tag them as building=yes and not add street or housenumber tags, since it is hard to tell from aerial view. As you can see, I have already started with this.

In March (as temperature permits) I will begin walking every street. I will correct wrong street paths, add access=* tags and add information about building type and address. I will also use my hiking tours to get a (hopefully) complete view of the hiking trails around Zirl. This will go on until the end of July, only interrupted by some time after the license switch where I will remap nodes that had to be deleted (though that should not be too many). I do not plan on remapping before the switch.

I hope to be done in August, when I will start my second ground survey and will go around and make sure that all data is correct, especially addresses and house shapes.

I hope that I will be done with this before it gets too cold to run around with a GPS (can't use gloves because then I can't take notes), so that I can spend the rest of the year checking the map from my computer.

It will be an interesting year for OSM and Zirl!
