Hi again :)
I just changed that: "farmland" isn't all wrong but a better tag for tree plantations is landuse=orchard,trees=coconut_palms.

cheers,
Matthias

Hi Nishanta,
there's an unclassified highway parallel to where you mapped thalangomuwa polkatuwa road. Didn't you just want to upgrade that to highway=tertiary? If not, you have to remove it, otherwise there will be confusion.

cheers,
Matthias

Hi, welcome to OSM! :)
A few notes on this edit:
please don't name things with what they *are*, only with how they are *called*. You can use building=house (as you did on a few already) to indicate that this is a residence as opposed to say building=industrial, and if a house should have a name like "Monkwell Manor" "The White House" or so, you can name it of course, but usually houses don't have names. And there was one node on the northeasternmost houses that was itself tagged as a building - it shows up as a little house icon in JOSM. It's easy to overlook, you probably knew already that you tag either the outline or a single node, right?

I've fixed a few things:

Please stop downgrading existing roads. This one even has an official name ans is mapped as paved (apparently, Bing imagery is fairly outdated, but even so it's clear this is more than an agricultural/forestry road) so "track" is completely wrong. Adding badly categorized ways isn't exactly nice but as long as I can clean it up, whatever. But changing existing roads in a way that will break routing is vandalism and I'll just revert it if you keep doing that.

OK, thanks! I guess someone should make a separate area for that at some point but for now I'll just add the buildings :)

cheers,
Matthias

Hi Alejandara,
please don't do this. Those reservoirs are not wetlands and the residential streets are not tracks. The HOT job is to *help* local mapping, right?

cheers,
Matthias

Hi,
you mapped that hospital within another hospital. Is that the name of a specific clinic building?

Also, parking_aisle ... no :)
Looks like tagging for the renderer, to make that street look smaller, right? It's also a small unpaved street serving all the residential area. highway=service was wrong before already of course.

cheers,
Matthias

Hello again :)
Those "tracks" are proper unpaved residential highways indeed. See wiki: highway=track
"Do not use tracks to represent unpaved streets in built-up areas [1], that would be considered tagging for the renderer. In this situation, classify them as usual according to the conventions in your country, and also provide a surface=* tag."

Hola Alejandra,
please don't change all those lakes to wetlands! As you can often see from one straight-ish edge, these are artificial irrigation reservoirs; Sri Lanka has very few natural lakes. So the reservoirs are usually very shallow, warm, and almost universally overgrown with water plants, so they look more like swamps although they're not. Often people tag them as natural=water, water=lake which isn't strictly right either but close. I usually use landuse=reservoir, reservoir_type=water_storage.

cheers,
Matthias

Hi Olla,
I've been observing this. The SL provincial governments seem to have been mapping a lot of data related to water and disaster management on OSM lately; there are fairly large groups of people involved in trainings, field surveys and what seems to be manual transfer of data from some kind of official GIS. Therefore I assume *what* the guys map is fairly reliable, unfortunately the same can't be said about other data qualities. They have some weird ideas about tagging - relatively few untagged ways, complicated technical refs or generic descriptions as names, made-up tags etc.
I'd say leave it in unless it's obviously wrong, like waterway catchments mapped as natural=water and such. I've been trying to clean up the tagging for a while, haven't gotten around to finding the responsible organizations for some better coordination though.

cheers,
Matthias

Hi Tom,
does this fountain in Saphang Len pond actually exist? I've left VTE so I can't check but it's not on the satellite pics.

cheers,
Matthias

Hi,

please don't use water=tank, it doesn't exist as a tag. You want landuse=reservoir, reservoir_type=water_storage for artificial tanks, natural=water, water=lake for natural lakes.

cheers,
Matthias

Hi,

please don't use water=tank, it doesn't exist. You want landuse=reservoir reservoir_type=water_storage.

cheers,
Matthias

Hi,
I noticed you are adding quite a few untagged ways. JOSM should warn you about issues like this before upload - please fix all errors and warnings like this when you add data. Otherwise your work is basically lost as it won't show up anywhere without tags.

cheers,
Matthias

Hi, thanks for tracing! Keep in mind this is rural Sri Lanka though: those are regular unpaved residential streets that people drive on, not "open to all non-motorized vehicles and not intended for motorized vehicles unless tagged so separately" as paths are by default. Their surface may well look similar to the path here highway=path but for routing purposes it's important to remember they're really meant for motor vehicles, too, in this part of the world.

cheers,
Matthias

OMG, pu-leeze! Don't do that!
Why in the world are you setting tags like layer=-5 and smoothness=horrible on a concrete road?! Look at the examples: smoothness=* How does the road look like? Do you need an off-road vehicle to drive on the concrete road?
It's nice if you can contribute local knowledge about names and such, but to avoid causing more work for others, please read a bit on what the tags actually mean.

cheers,
Matthias

Hi,
please don't name your streets with generic names like "residential" - that's *what* the street is and expressed by highway=residential already, it's not how it is *called*. If you don't know the name, just leave it blank.
Also, layer=-4 is strange, did that have any particular purpose?

cheers,
Matthias

Hi Amy,
did you actually use Bing there? Because from what I see on Bing here, the southern and northeastern bit of that loop is definitely an irrigation canal, not a highway. I'd say unclassified is fine for the southernmost stretch, but the northern one should be a grass or dirt track.
I might be wrong, Bing might be outdated and your more up to date GPX say something different but I thought it worth checking.

cheers,
Matthias

Hi,

please don't name things with *what* they are, only with what their actual *name* is. I.e. a path should not have name=Path and natural=rock not name=Rock. It adds no useful information and looks confusing on the map. It's just fine to leave those fields blank if you don't know it or something like a path just doesn't have a name.

cheers,
Matthias
