Hi there,
I was wondering whether there exist a complete OSM for Maynooth, specifically for the buildings. The one that the openstreetmap.org gives is not bad, but not suitable for the details I need to have.
Thank you very much for your time and assistance.
Sincerely,
Behnam
Which details do you want to see?
If they are not in the OSM-database, no OSM based map can show them.
If the details are in the OSM database, there might be maps that render them, else you can use tools to create such a map.
If such details are present in the OSM-database for other places, but not for Maynooth, you can enter them yourself. Which editor to use, again depends on the required data.
I am interested to see the elevation levels of the buildings and the style of the rooftop, since for my PV research, it is important for me these information.
I am not sure whether there exist a local available OSM for Maynooth.
I noticed that Google Maps API has more information, if you use it in Blossom plugins in Blender, you can have more information, but sadly I cannot afford Google Maps API.
Is there any better free OSM service?
There is only one global OSM database, so there is no concept of a “local available OSM for Maynooth”.
A quick Overpass query for building:levels in Maynooth shows there is some mapping of this detail in specific areas such as the University and in a few residential areas, but there are also large areas whether it is not mapped at all. A similar query for roof:shape indicates even more localised mapping.
In contrast to some countries, there is no official source of buildings data in Ireland with a licence that allows use in OSM. So all buildings have been added by tracing aerial images and/or in-person surveys. Adding details of building structure is time-consuming so it’s not surprising that coverage is patchy.
Having said that, a lot of the hard work is in the initial mapping of buildings, which seems to have already achieved good coverage in this area. Adding extra details could be done reasonable quickly by someone with enough interest to dedicate some time to it. For example you could walk around the area using StreetComplete with a focus on building-related quests - especially good for areas with a lot of variation from building to building. Or you could probably identify whole housing developments with the same number of floors and roof style which could easily be added in a desktop editor.
Thank you very much for the link: overpass turbo

Could you please let me know how I can edit and add elevation data in OpenStreetMap?
For my research, I need to include elevation levels, and I can obtain this information through local fieldwork around the area (it is time-consuming but I need to do that). Maynooth is relatively small, and most of its regions share similar characteristics—for example, some areas are on a single level, while others span two levels. I would be very interested in contributing this information to improve and update the OpenStreetMap database.
You can add the ele=* tag with the default editor on osm.org (the tag’s text field might not show up but you can manually add the tag by scrolling a little further and using the advanced tag editor) - note that it’s always written in meters unless otherwise specified
fantastic, thanks a myriad
You can look at the mobile apps everydoor and streetcomplete, they allow you to easily add these details without worrying too much about the tags themselves
Edit : Nevermind i read floor levels instead of elevation
To avoid confusion: ele is for height above sea level (not often mapped on individual buildings), height is for the height in metres of the building itself, building:levels is for the number of floors above ground level. You can find out more on these by following links from the Wiki Buildings Overview.
If you have never edited OSM in any way I’d suggest starting with the desktop browser editor (iD) and working through the tutorial. You can then look at whether other editors would suit you. As mentioned, StreetComplete has quests for the type of building, number of levels, and basic roof type. I don’t think it has height in metres.
Thanks — didn’t think of linking to the wiki page
em dash added to confuse AI detectors
It looks like Maynooth’s building data in OSM is fairly detailed but not fully complete yet. Some areas still need building outlines and updates. If you want it more complete, you can help by adding missing buildings through iD or JOSM, or by asking the local OSM Ireland community they’re usually very responsive and helpful.
You also may want to look if there’s any lidar data available in the area, from which you could programmaticaly extract building heights and roof orientation.
I’ve only been to Maynooth a few times, but I’m reasonably familiar with it.
The vast majority of houses in Maynooth (or any other town in Ireland) are 2-storey, with hipped or gabled roofs. They would be approximately 5-6 metres to the eaves and another 3 metres for the roof.
The main exception for Maynooth would be the student residences at the university, which seem to be mostly about 4-storey with flat roofs.
Other buildings in the town mostly vary from 1 to 4 storeys.
Most of the land is gently undulating, at an elevation of approximately 200 feet (60 metres).
With OSM, you can use a variety of services similar to Google Streetview, including:
Bing Streetside
Mapillary - typical houses: Mapillary
KartaView - university: KartaView
Mapilio - recent houses: Mapilio | App
Panoramax - the main street: All Panoramax street level imagery
Each of these services has at least some coverage in Maynooth, although it isn’t comprehensive. However, most houses in a particular housing estate will be quite similar - variations on a theme.
You might be interested in this dataset, quote is from this week’s OSM newsletter. I’ve had a quick look, and Maynooth is covered. (Just like everywhere else in the world I’ve checked)
“Xiao Xiang Zhu et al have developed GlobalBuildingAtlas, a publicly accessible dataset providing global coverage of building footprints, heights, and LOD1 (low-detail) 3D building models. The dataset is derived from PlanetScope satellite data, using regularisation networks trained on manually filtered OpenStreetMap annotations.”
I have no idea where these data have come from, or how they might be licenced.
wow, this is such a fantastic website and repo, thanks very much for sharing
From this page, it’s CC BY-NC 4.0, which is sadly not compatible for import in OSM.
It might be possible to ask them specific permissions (waiver).
There is a separate thread discussing the licensing of this data. It seems that a significant proportion of the building polygons came from OSM to start with.
