Hi, you need to fix these invalid multipolygon relation in two separate areas.

Hi, you can choose Esri imagery instead of Bing which displays the buildings

I have fixed the wooded multipolygon area now

Hi, looks like there are a few mapping errors to do with how you construct multipolygons to fix here

I have reverted this changeset and will leave to the mapper to remap the business to a more suitable location

Hi, you have placed a business name on a roadway centreline. Please place the business at the building site you operate from and preferably with more details.

Hi, you have added your digital marketing company to a power substation in Berwick. Your website says your office is located in
Cranbourne North. You should locate this at the office you operate from.

Hi, we map houses by zooming in and precisely drawing the outline of the house itself instead of the plot of land it sits on.
If you wish to display the plot shape then map the fence lines accurately is a good alternative.

Hi, this appears to be missing it’s outer
relation/20052530#map=18/-27.550730/153.158080

Hi, the multipolygons is invalid as outer ways cannot share a side.
Can you use simple polygons instead or use a one simple polygon encompassing the lot.

Hi, are you going to monitor this situation and update the map as soon as the tree is cleared?

I think it is ok now. I made the big sand hill a multipolygon. The wood is a mp but not including the small segment of sand along the beach. Patches of wood in the big sand hill are outers for the wood mp and inners for the big sand hill mp.
I took the tag natural=wood off the patches of trees in the sand hill because they are tagged as wood in the wood relation.
There is another area of sand joining the big sand hill but probably not considered part of the big sand hill so I made that a multipolygon so I could use the shared segment in both.
Hope this helps.
If you get deeply into micro-mapping complex natural areas you may need to use simple polygons with overlapping sides as mp may not be able to be resolved.

If you prefer I can try to fix if you put the area back.

Hi, a few problems here due to invalid multipolygon structure.

Josm validator detects these but it
probably easiest to read the wiki and check the invalid types.

Hi, I have reverted this. You need to map your business to the physical address you operate from instead of the edge of a park.

I have fixed this now

Hi, you have joined some paths to the powerline in many places. You should zoom in much further as paths should not connect to powerlines.

Hi, these are incorrect tags for a gate on land.
seamark:type=gate
waterway=lock_gate
Here is the wiki for the gate you want...
barrier=gate

Fixed in changeset/176379076

I have reverted this changeset as I am unable to verify the physical address.
