Individual trees are fine, just more work. It can be difficult to separate the trees from the forest when the trees form a canopy. Rows of trees are common along fences, roads and paths in cities.

Fixed. A street lies on the Jacka/Taylor admin border which is the source of the error.

I can see what has happened and will fix it.

This change set should not include changes to the administration boundaries for Jacka / Taylor. Are you say the boundary was moved, or that a relation was removed from the boudary line (the line can be used in multiple relations). The relation for the admin boundary should not have chaged. Thanks for your email. I will make some checks.

A dozen cows seen in the paddock here osm.org/?mlat=-35.2771&mlon=149.0719#map=16/-35.2771/149.0719

Yes, true. Not many farms left in Canberra. Some hobby farms, e.g. these 2. Close to the city for work. Some animals. Private property. Very small "paddocks" 30x40m are usually for horse(s) - see north William Hovell Drive .

Another point. A paddock (meadow) is a closed relation. If the fence is missing or its got holes big enough for a truck to drive through, then it is not a paddock. "closed fencing and gates"=meadow and "unfence area (or gaps)"=grassland. Fenclines are visible in OSM.

Agree. Small, working farms in this area. I am not suggesting one cow. If a grassland is not used for agriculture but a meadow is, what is the difference? I think one cow in the paddock is enough to change the tag. "no cows"=gassland

Yes, it is a paddock. Two small farms, Glenloch and the one beside it. Previously "meadow" for grazing. Grassland implies that there is no agriculture. Both are grass though. Does seeing a cow count?

The Arboretum is a small and well defined area.

What evidence do you have that the relation is correct, or need? The satellite photos provide no information about this. :-)

Relation was in error. Satelite photos are out of date. See Whitlam updates today. Wrong fence lines in Glenoch section. Surveying continues

For 2. LPI NSW basemap has value of peak 139m and cliff height above sea level 100m. Same as previously.

I have walked the area often with GPS.
Cliffs height vary continuously due to the nature of the terrain. Move 10m in either direction and the height is likely to change. Height above sea level or vertical drop? Many cliffs are not exactly vertical either. The real world is a messy place
I try to make a good estimate of the max height of the cliff and stop drawing cliffs when they are so low they see to be threat or no all that steep.
Here is source data for the sections.
1. Cape St George Historic Lighthouse is 67 m abover sea level. It drops pretty much straight in to the sea. I estimated the cliffs here at 50 m.

2. Headland north of Steamer's Beach has a peak about 130m above sea level, but the cliffs are low at about max 100m. There is a magnificent view from Steamer's Beach. Cliff height estimate with a DEM – Digital Elevation Model - LDIR data I think.

I have deleted my change to the river poligon. Please feel welcome to check it

correction "area marked Whitlam"

Thanks for the link. There is record of a change here. I did not make any changes to the river. An area "beach" was added adjacent to the river. That may have something to do with it.
In any case there is still the assumption about my intent which is simply incorrect.
Again, be careful of the word "blind".

Thanks for your comment about the life cycle prefix

Valley Track has been there for years. A new pipeline was buit from the water tanks at the top of the hill to Whitlam in the south. For the last 6 months this area of Hawker has been block off behind fences and a detour provided. I expect them to open the track again once the project works is completed.
