Welcome to another video.
In a previous one, I had talked about how to map thatched roofs
on OpenStreetMap,
and in this one, I want to talk about how to deal with
buildings where only part of the roof is thatched
and the other part might be slated or corrugated or something.
I'm talking about this example here, and it looks like it's all thatched,
but there's part of it there in the back
that isn't.
So, this is the one we're gonna deal with.
Here, in this survey, it says it's in Gattabawn,
but it's actually in Rathlogan
in West Kilkenny.
It is here.
There's the motorway, the Dublin - Cork motorway,
and it's here; it's just across the graveyard, so it might be worth visiting.
I haven't been there yet.
I will hopefully go at some point.
So, there it is.
I will go and edit. I'm already logged in with my username, the usual,
and I click on "edit".
And I'll just make the data layer invisible,
so you can see what it looks like.
This part here is thatched,
as you can hopefully see,
and this part is not. I can't see what the roof material is,
and it might actually be an extension from the picture here,
because it seems to be here,
but there's nothing in the photograph.
I think this part here is called a wind break.
And then we have this garage or something
which is this part here.
It is mapped as one building,
and we're gonna improve on that, first of all,
by defining it as a house, because that is what it is.
That's the house,
and it has four parts: it has the
thatched part with the gabled roof,
a whatever roof type this is - gabled,
and then it seems to have two extensions here
with probably skillion roofs.
So, we're gonna make up this from four building parts.
This will give us good practice.
And
first of all, we have to define a new building relation,
because we have to put all these four parts into that relation,
and we click on "new relation" here on the left,
and just choose "relation",
and the type is "building"
So far, so good; that makes sense
and the outline of the building - the role is "outline".
Also makes a lot of sense.
So, that's the first part done.
And we can add more information to this later on.
And then, I'm going to start to draw the bit that has the thatched roof.
I'll start here in the corner go up to here, across
and back to try to make it a rectangle.
It's not going to be perfect.
And then, I can either go down to "area"
or I can click on "building",
scroll down and add ":part" here.
"building:part=yes"
or I could have just redefined "area=yes" into "building:part=yes".
I'll do that with the next one, I think.
And then I have to add this to the relation,
and I just click here
and it's just called "relation",
because I don't know if this house has a name,
and this role in the relation is "part", because it's a building part.
And then, I can add the roof material,
"roof:material=thatch",
and in the picture, it looks like it's gabled, and also
on satellite view, it looks like it's gabled, so we can add that as well.
"roof:shape=gabled",
and it seems to be only one building level.
And we can add that actually up here or we can type in "building:levels=1".
And there don't seem to be - very difficult to say in this picture -
there are no windows in the roof, so there's no roof level, so to speak,
and then the next bit here,
the next rectangle.
and to finish drawing this, I just hit the ESCape key,
and it's automatically highlighted.
And as I said, I'm going to do this different now,
Scroll down, at the bottom usually is "area",
and then I'll just replace "area" here with "building:part".
And this also is a gabled roof,
so "roof:shape=gabled".
And I think that this direction here is longer than this one,
so I have to add "roof:orientation=across";
that's for the 3D mapping
which I talked about in one or two previous videos which i will link up in the corner.
So this is this one. I can't add the building material, because I don't know.
It's also one building level.
And then the next bit is this one here.
One extension;
I'll go for "area" again and replace it with "building:part",
and of course, I've forgotten something - as usual.
"roof:shape=skillion".
I highlight this one and the last one, because I forgot to add them to the relation,
like so, and give them the role "part".
And the last bit then, the last piece of the puzzle, so to speak, is this little bit here,
and I'll go with the other method: "building:part=yes",
add it to the relation
as a part,
and the roof shape is also "skillion".
And the extensions are usually the same building height, so they're
level one,
and then, I will highlight them all and to square them off, because obviously, I can't draw perfect squares
highlight them all and hit the q key on my keyboard,
and that should square them off.
I don't know, if you could see that now, but believe me - they're all squared off now.
And that's all we have to do.
I could add also that there's a wall here, and there's a wall here
and a driveway here or service road,
This is it.
And I will upload this now,
call it "split building". I've seen that ... I've done that before
and at the hashtag #thatch as i did before.
Source "Esri", and I also add "street-level photos", because of the picture in this survey
which I will talk about in an upcoming video.
And then I can upload this.
And if I wait for a while and refresh, it shouldn't show anything new apart from
the wall and the road here.
If you don't do it in building parts in relation, you would have gotten four different parts
shown as four squares; they're all in the one thing, but it doesn't look as nice, you know.
And you could add then, if you knew it,
if for example, I got in contact with the owners, and they could tell me
when the part that is thatched was built, I could add that to this part of the building,
and then I could add the dates for the extensions as well.
I probably won't find out - maybe somebody will,
but that is something we could do, could add dates for every extension.
So you see that didn't change anything to the building, to what it looked like and
it added the wall and the driveway,
but the data is there. If i open the data layer here,
you see it has those four bits,
this is the whole house; it might be
difficult to click on the single piece now, but you can always choose them
on the side here so that's the one the thatched one,
and that's how you do that.
And I hope you found that interesting.
