Using the heritage list of protected buildings and monuments of wikipedia, I managed to map all such buildings in Mechelen en Lier.

The result can be viewed on the geschichtskarten, e.g. Lier

Up to the next town. Antwerp ?

Great! Thanks a lot! I also like to map heritage buildings.

I don't know if you already know a little hint on how to map these buildings much quicker. In wikipedia you have the coordinates. With following link, it's possible to show them on a google map (thanks to kmlexport): (for example)

If you delete the "&redir=google" it's possible to download the kml file of all coordinates within a wikipedia-article. Then you convert the kml to gpx file on or with GPSBabel application.

You get a list of waypoints which you can import into JOSM. This way its in my view much quicker to map heritage buildings.

Have fun! :-)

Oh another hint I got some week ago: there are heritage presets for JOSM. This way its more comfortable to map heritage buildings. You find it here: You can include them into JOSM in the JOSM-Properties -> Presets "Denkmaleigenschaften". See post:

I saw that you tagged buildings this way: image = I think it's enough to only write File:Antwerpen_Brandweerkazerne_Halenstraat1.psd.jpg

Have fun. :-)

Hi Poppei82,

thanks a lot for both hints. I didn't know about the kml export link. I'll have a go at it.

I wrote some presets for JOSM myself (BENELUX) that has dedicated settings for the Flemish information. It tweaked o.a. for monuments that are listed by Onroerend Erfgoed. The is the Flemish institute responsible for listing the historic buildings.

Nevertheless, I'll have a look at the preset that you mention. Maybe I can use some ideas to improve my own preset a bit.

Regarding the partial/full link to commons wikimedia. It's just easier to copy the full link than part of it :-)

With the OpenData plugin of JOSM, one can directly import kml files. So there is no need to convert them first with another tool

Maybe it's possible to merge both presets? I see that the presets I mentioned are interenational for several countries. So maybe it would be better to include Flemish presets? I don't know, I am not the maintainer.

Sure, the commons-link is easier to copy. :-)

Thanks for the hint that I can import KML directly! Great!

Nice work you did in Lier. Seems to be a nice city. :-)

Oh, have you already seen the NoImage-GPX in the lower right corner? There you get waypoints of heritage buildings which have no photo. Perhaps you've heard about the Wiki Loves Monuments photo contest. This could be usefull, if you do some walks in this nice city. :-) I will also upload some photos of heritage buildings in September.

Have fun! :-)

Thanks for the compliment on the work in Lier. It sure is a nice town. The work that I did makes it tempting for me to visit it again after all those years. However, I usually try to find walks that our dogs like as well. A visit to a town is not high on their list of fun things, especially not with the current temperatures :-)

Your description of the KML file got me thinking. Maybe I should try to write a python script that keeps even a bit more information from wikipedia. I might be able to directly create an OSM file with the address information, links to the heritage website, a description and so on. I'll give it a try later on

As for the presets, the BENELUX one is mainly targeted to Flemish mappers. It contains more items than only heritage. e.g. fixed operators for mailboxes. It's also completely translated in Dutch.

I can use the idea from the heritage preset to include a dropdown for the type of building. The heritage preset is more focussed on the heritage "rules" and therefore includes more data such as a start date of the protection. This information is not in wikipedia. I don't really dare to use more information from the OnroerendErfgoed website. My preset has more fields for the different types of names (name, old_name, addr:housename, alt_name)

It would be better to have 1 big preset, but a dedicated one per country has the benefit that one can set some default values for operators and other country specific data (maxspeed rules with trafiic zones= be:rural e.g)

I knew about the No Image GPX link, as I did all the translation work to Dutch and English :-). I used such a GPX-file for a walk near Bornem. Still have to upload the images though.

Cool! I already asked for such a script which could make it possible to automatically transfer this wikipedia knowledge into OSM. I think this would be another nice project which integrates the both free sources of knowldge. However I am no coder. :-( If you need a tester or translator it woukd be a pleasure for me.

I also asked for this NoImage-GPX feature and one day after my forum post it got implemented. Thanks to the coder who did great work!

Nice that you translated this page! I think this page is not only a heritage for citys and so on, but also an important heritage for the mankind. Everyone can get free access into heritage all over the world! No only the facts but also where they are located. That's an amazing project!

As I saw the presets last time, also the specific neds for Poland's heritage buildings were implemented. So that perhaps it is already international and fits into country-specific information. Woud be great to have one tool that is specialized on heritage wherever it is located. I think it is no problem to tell the preset that for Belgium there are other default values. But as I mentioned before, I am sadly no programmer. Also I think you don't need to fill in all information.
