I saw that you changed the Vanimo-Aitape Road from Secondary to Primary Road. That road is currently in such a bad shape that it does not make a lot of sense to classify it as a Primary Road. See the PNG National Road Strategy, that classifies this section as a "missing link": https://www.works.gov.pg/files/DoW_NRNS.pdf

And would it be possible for you to please write proper comments regarding your changes in the future?

If you want to mark the area around a church, please use the tag landuse=religious. The way you have been marking these areas currently is as church buildings, but the building tag should only be applied to the buildings themselves. Also, campsites are areas where tourist put up tents, not work camps.

The Tag "unmaintained track" should only be used for logging and plantation tracks or access to gardens, not for roads connecting villages (regardless of how badly maintained the roads are).

Hi gibranhalil,

With airports, please make sure that you use the correct IATA and ICAO codes (these two are always different, never the same). Many you can access on the ourairports.com website. Also, OSM uses meters, not feet.

Best wishes,

The Coastline here is placed way out in the ocean in my opinion. Maybe good to recheck it and have a look at the wiki on the coastline-river transit place: osm.wiki/Proposed_Features/Coastline-River_transit_placement

Sorry, disregard the statement about mud, just realized that you must have just moved some nodes, not created this particular landuse.

Hi Nicxon,
Oil palm plantations should actually be tagged as orchards, not farmland (see the OSM wiki). The same would be true for coconut and rubber plantations, by the way. And what you classified as mud, is probably better tagged as shingle (pebbles and gravel deposited by flowing water). I will make the necessary corrections. But thanks for your effort in drawing land use areas, it is highly appreciated.

Hi. You laid this river over an existing but more poorly mapped creek. I will fix this, but please take care not to overlap rivers or roads over already existing features.

What criteria did you use in modifying the road types? I suggest you have a look at the East Africa Tagging Guidelines, which are the basis on which to make decisions also for Papua New Guinea. The tertiary roads that you reverted to unclassified should in my view qualify as important enough to be tagged as tertiary roads.

The golf course does not have an official name, I mean, at least as far as I and my friend know. It was just called "the golf course". Makes sense to put it down as "Lihir golf course".

Friend of mine who worked for Newcrest on the island. It does not really have an official name.

Could you please tag buildings such as these as buildings and not sheds? These are family houses, not workshops or storage houses. Also, it would be good if you could make the buildings square (press q after you have tagged them, or right click and then choose the rectangular tool).

Why? It is clearly a residential road. If, then this should be connected to the main highway, and the surface tag should be changed to dirt.

This road has a clear connecting function, therefore should not be classified as track. Track, according to OSM guidelines, should be used only for agricultural / forestry use. And since this is Papua New Guinea, where planes are often much more important than roads, you will encounter a lot of "floating" roads, as they lead away from airstrips (which hasn't been marked here yet), to other villages. One could argue that this could be classified as a path (as there most likely is no vehicle around to use this road), no?

Again, why track? Track should be for agricultural / forestry purposes according to the OSM guidelines. This is a connecting road from the shore up to Salamaua Secondary School. If not unclassified, then what else?

Why track? Track, according to OSM guidelines should be used for roads for mostly agricultural use, forest tracks etc. This road here goes straight through a village. If at all marked as road and not path (as it does not have any connectivity to anywhere else), then it should probably be mapped as residential, no?

Why remove it completely and not just change it to path? There clearly is a path visible on the satellite pictures leading from the Sepik River (where people get off the boat) to the village with airstrip.

Thanks, my mistake. Must have been in a hurry...

Hi. Why change it to unclassified? This is an asphalted road that has enough space for two vehicles to pass, and it connects larger villages (and an important national high school). According to the East Africa Tagging Guideline, that should be followed in the case of Papua New Guinea, this road should classify as a Tertiary way.

Hi,

Great that you are drawing in Oil Palm Plantations. They should be tagged as orchards, though, not farmland. See:
landuse=orchard
