You moved buildings of On Shing Terrace SW 5 meters against its actual position

Offset found: moving 3 meters north may be better in accuracy

I know there is an offset when using Esri imagery

Ref: changeset/73642861

fixed

There is an unrectified offset error around Mongkok area of "Esri World Imagery". You may use this link (http://www.mapwarper.net/maps/40670) to assess some of your works.

offset似乎誤差超過20米..

southbound lane is temporary closed now

Reverted at changeset #63246449: Multi-storey buildings must be positioned at its base, not its roof.

This is a carpark dedicated for coaches (total 31 spaces) according to TD website

呢d應該都係以前mapper用Bing衛星圖拉線留低既蘇州屎黎，因為昔日Bing衛星圖香港部分地區有扭曲同走位現象

我有d擔心，你用果個offset，會唔會誤差太大(同政府地圖比較)

吐露港公路擴闊工程及龍山隧道工程正在進行，期間會將大窩西支路重新定線

just resembling my own survey results by comparison to improve accuracy (Government map doesn't provide locations of zebra crossings but I have)

I created the new oneway path by referencing actual coordinates from Government map as the given aerial image looks a bit distorted

Coordinates of roads and buildings nearby have to be rectified soon
