@theel0ja : The orthophotos provided by the Helsinki region seems to have a higher quality than the national MML orthophotos. They are open under the CC BY 4.0 license and distribution is actively encouraged: https://hri.fi/en_gb/helsinki-region-gis-data-freely-at-your-disposal/.
Would you mind asking for confirmation in an e-mail to hri.fi that their data is used in OSM? Your request would need to mention that OSM is using the ODbL license and that attribution will be made at the https://wiki.openstreetmap.org/wiki/Contributors#Finland page.
I can then help adding the orthophotos for the region (Helsinki, Espoo, Vantaa, Kauniainen) to ELI and JOSM.
Thanks @theel0ja! As @NKAmapper rightly said, we need a confirmation that this data can be used in OSM. Unfortunately, CC-BY isn't fully compatible with OSM's ODbL, as that blogpost you linked to explains. Once you have a confirmation, I'll be very happy to add this.
This is the format we have used in Norway for most of our requests:
"I am one of many contributors to OpenStreetMap, a free, editable map of the whole world that is being built by volunteers and released with an open-content license.
We have seen that Helsinki Region Infoshare has released orthophotos and other open datasets under the CC BY 4.0 license. We would like to get your confirmation that these datasets may be used by OpenStreetMap.
OpenStreetMap is using the ODbL license for its data. Attribution to Helsinki Region Infoshare will be made at OSM Contributors."
Great! You now have the permission to use not only the orthophotos but also all the other open datasets from HRI.
I would recommend that you now post both your enquiry and the reply from HRI to the Finnish OSM forum so that the permission is recorded there and that anyone may comment.
I will now prepare for getting the orthophotos into ELI and JOSM.
I believe this didn't go quite according to the copyright regulations. Firstly HRI isn't the owner of any of these dataset and thus isn't eligible to give out any rights associated with the datasets. The municipial orthophotos are owned by the municipalities (Helsinki, Espoo etc.) themselves and the Helsinki Region orthophoto is joint acquisition by HSY, HSL, Helsinki, Espoo and other municipalities so there are multiple owners of that datasets. See https://forum.openstreetmap.org/viewtopic.php?pid=710304 for more information.
Hi Markku!
Thanks for bringing this to our attention. I see three things here:
- What should the right name and attribution be?
- HRI looks like the correct point of contact for this kind of inquiries to me. @theel0ja was explicit about OpenStreetMap being licensed under the ODbL. Ms Lahti at HRI is the project manager of HRI and works at the City of Helsinki Executive Office - in other words, she's not just any random clown. Have you been in touch with her to clear this up?
- Could you or Henna-Kaisa from HSY please see about quickly getting us an unambiguous permission like the one you linked in the forum?
Hello all. Answers to your questions below...
What should the right name and attribution be?
- The required attribution depends on which photo set was used? Could you or someone else please specify which orthophoto was used in this case? If it was (this one) then the attribution question was already answered by Henna-Kaisa@HSY here. The name for the photo could then be eg. "Capital Area Ortophoto 2017"
HRI looks like the correct point of contact for this kind of inquiries to me. @theel0ja was explicit about OpenStreetMap being licensed under the ODbL. Ms Lahti at HRI is the project manager of HRI and works at the City of Helsinki Executive Office - in other words, she's not just any random clown. Have you been in touch with her to clear this up?
- I had a meeting at HRI (with Ms Lahti and others) on wednesday 5.9. where I came aware of this "HRI ortophoto" in ID editor. This raised some questions at the meeting so I started to investigate what it was all about. After that I've mailed Lahti and others but haven't had the opportunity to discuss this issue with them.
- I know Ms Lahti and indeed know she's no "random clown" :-) However everything isn't always what it looks like. HRI does indeed help to open up a lot of data. But they're seldom (or never?) the owner of the data themselves. Their main focus is to promote open data eg. by creating this open data catalog for the region where data from many different copyright owners (municipalities, cities and other govermental authorities) are collected and distributed. @theel0ja was indeed explicit about OpenStreetMap being ODbL based but to me it looked like HRI's answer was more or less a standard answer containing basic CCBY40-licence instructions like "the original data source should be mentioned somewhere". My guess is that they didn't quite understand what the "OSM-part" of the question requires. I'll ensure this thing on monday by contacting HRI. Furthermore it looked to me like @theel0ja misinterpreted HRI's message (example) regarding the right copyright attribution just as I already mentioned in my OSM-forum message.
Could you or Henna-Kaisa from HSY please see about quickly getting us an unambiguous permission like the one you linked in the forum?
- HSY was the main administrator of this ortophoto project so I would pass the task to them. But It probably requires acceptance from all parties involved - so I can't promise any quick response. This list of involved parties includes municipalities that aren't part of the HRI steering group so I can't see how the steering group could be authorized by the data owners as suggested by @NKAmapper.
After finding https://josm.openstreetmap.de/wiki/Maps/Finland and the URL-line with the link https://kartta.hsy.fi/geoserver/ows?SERVICE=WMS&FORMAT=image/jpeg&TRANSPARENT=TRUE&VERSION=1.1.1&SERVICE=WMS&REQUEST=GetMap&LAYERS=taustakartat_ja_aluejaot:Ortoilmakuva_2017&STYLES=&SRS={proj}&WIDTH={width}&HEIGHT={height}&BBOX={bbox}. I would say my guess about the photo being the "Capital Area Ortophoto 2017" was spot on. So the attribution would be ... "Pääkaupunkiseudun ortoilmakuva (C) Espoon, Helsingin ja Vantaan kaupungit, Kirkkonummen ja Nurmijärven kunnat sekä HSL ja HSY, 2017" and the copyright owners : Espoo, Helsinki, Vantaa, Kirkkonummi, Nurmijärvi, HSL & HSY.
I just phoned Tanja Lahti @ HRI - she confirmed that my assumption (below) was right.
HRI's answer was more or less a standard answer containing basic CCBY40-licence instructions like "the original data source should be mentioned somewhere". My guess is that they didn't quite understand what the "OSM-part" of the question requires. I'll ensure this thing on monday by contacting HRI.
This case seems still to be open and at least ID-editor still claims these to be HRI ortophotos. Could someone please change the name and attribution of the photo to the ones i presented above (7 sep)?
In development version, it has been changed.
http://preview.ideditor.com/master/#background=hri-orto&disable_features=boundaries&map=14.62/60.1908/24.9075
Correct, the name and attribution text were updated in ELI a month ago: #554 diff
However, iD has not had a new release since 29 August. I could ask over at iD if they could do a special update for this imagery.
If only we could ask @bhousel when the next version of iD will be released :)
Now the attributions seems to be updated to the production releases of ID & JOSM. So, this task could probably be closed unless we wouldn't like to add another ortophoto? :-) This 5 cm resolution ortophoto over Helsinki city is far more detailed than this regional ortophoto (20 cm). Could this be added to the list as well? I believe it would be largely appreciated in the OSM community. I can ask for the needed permissions from the city as I allready have contacts there. But first could someone confirm that ID & JOSM can use this WMS-service? info : https://www.avoindata.fi/data/fi/dataset/helsingin-ortokuva-2018 ... WMS : https://kartta.hel.fi/ws/geoserver/avoindata/wms
Yes, the WMS works, and I agree that the quality is much better. Here is the url: https://kartta.hel.fi/ws/geoserver/avoindata/ows?SERVICE=WMS&FORMAT=image/jpeg&TRANSPARENT=TRUE&VERSION=1.1.1&SERVICE=WMS&REQUEST=GetMap&LAYERS=avoindata:Ortoilmakuva_2018_5cm&STYLES=&SRS={proj}&WIDTH={width}&HEIGHT={height}&BBOX={bbox}
I can help in adding it to JOSM and ELI (iD) if you get the permission and post it to the Finland forum. You may use the same wording in your request as shown earlier in this thread. You may want to phrase your request so that OSM gets the permission for all their orthophotos (not just 2018), so that this process does not need to be repeated next year. You may even want to ask them for permission to use all their open data in one go (this is what I usually do).
I believe this quality is available also from some of the other larger cities in Finland, if you would be interested in asking for even more permissions (or you could ask others at the forum).
Hello again! Sorry for the delay in answering. I believe that Helsinki is quite unique in Finland to offer this accurate aerial imagery as open data. I haven't heard of this kind of service from other cities. I'll push this issue foward this week by contacting the city of Helsinki and try to get their permission to this - which I believe will be quite easy as I already had some discussions about this last year and then they already agreed to give the permission or actually wodered why I even asked them for it. For them it was quite clear that if the OSM-editor just presented the copyright-attribution according to CCBY40-regulations then the new objects created with the editor could be licenced as OdBL according to OSM. I'll use a modified version of the request used earlier and ask the permissions for all their ortophotos. But I won't ask the permission for all their data. That I believe will complicate things to much as they publish open data that they're not the only copyright-owner too (as we earlier experienced with the HRI ortophoto) and they also publish vector data. With vector data we've used a different "permission scheme" at least here in Finland. With Vector data organizations have issued a permission like this one ... https://wiki.openstreetmap.org/w/images/7/75/HSL_permission.pdf

Hello!
I am one of many contributors to OpenStreetMap, a free, editable map of the whole world that is being built by volunteers and released with an open-content license.
We have seen that Helsinki City has released an ortophoto covering whole of Helsinki with 5 cm resolution under the CC BY 4.0 license.
https://www.avoindata.fi/data/fi/dataset/helsingin-ortokuva-2018
We would like to get your confirmation that this and also other later on released CC BY 4.0-licensed ortophotos from Helsiki City may be used in the different OpenStreetMap-editors.
OpenStreetMap is using the ODbL (https://opendatacommons.org/licenses/odbl/) license for its data. Attribution to Helsinki City ortophotos in accordance with the CC BY 4.0 license will naturally be presented when publishing the ortophotos in the OpenStreetMap-editors.
Sincerely, Markku Huotari

It seems that Timo has not actually granted any permission to OSM but merely quoted some of the key terms of CC BY 4.0. As explained here, Timo's last quote about additional restrictions is actually a problem because ODbL is more strict than CC BY 4.0 regarding the use of DRM.
What is needed from Timo is either a confirmation to your request, which would then be an explicit permission for OSM to use the orthophotos under ODbL. Such a confirmation may also be given in form of a waiver similar to the PDF which you have linked to a couple of messages earlier here.
