京杭运河镇江段是重要的航运水道,桥梁多为大型公路桥或铁路桥,跨越宽阔的水面。主要桥梁自西向东(大致方向)包括:

高资河桥/高资桥: 位于丹徒区高资街道附近。

润扬大桥(公路桥): 虽然不是直接横跨运河主航道,但其南汊桥(悬索桥)跨越长江,其引桥和接线工程会跨越或邻近运河相关水道(如运粮河等),是区域重要通道。

镇江西高速桥: 沪蓉高速(G42)跨越运河的桥梁。

镇江西互通连接线桥: 连接镇江市区与高速公路的桥梁。

戴家门桥/润兴路大桥: 位于润州区,是市区西部跨越运河的重要通道(S243省道)。

檀山路桥: 连接镇江主城区与丹徒新区的主干道檀山路跨越运河的桥梁。

九华山路桥: 九华山路跨越运河的桥梁。

官塘桥: 位于官塘桥路,是市区南部跨越运河的重要通道。

沪宁城际铁路桥/京沪高铁桥: 高速铁路专用桥梁。

沪宁铁路桥: 京沪铁路(老线)跨越运河的桥梁。

丁卯桥路桥: 丁卯桥路(金港大道市区段)跨越运河的桥梁,是连接镇江主城区与丁卯、大港的重要通道。

谏壁公路桥/越河街桥: 位于谏壁镇,连接越河街,靠近谏壁船闸。

谏壁闸桥: 位于著名的谏壁船闸枢纽处,通常指船闸交通桥或附近跨越节制闸的桥梁,是连接运河两岸的关键节点。非常重要。

雩山桥: 位于丹阳市访仙镇附近(雩山脚下)。

陵口大桥: 位于丹阳市陵口镇,是跨越运河的公路桥。

二、 镇江市区古运河上的主要桥梁 古运河从平政桥(京口闸)进入市区,向东南流经市区,在谏壁汇入大运河主航道。这段河道较窄,桥梁密集且更具历史人文气息。主要桥梁自北向南(入江口到东南方向)包括:

平政桥: 位于古运河入江口(京口闸遗址附近),历史悠久,是古运河的起点标志之一。

新西门桥: 连接新西门内外。

中山桥: 市中心重要桥梁,连接大西路和中山路。

解放桥: 位于解放路上,靠近伯先公园。

虎踞桥: 历史悠久的古桥(现为复建),位于南门大街北端。

南水桥: 位于正东路西端。

珍珠桥: 跨越珍珠路。

塔山桥: 位于塔山路。

丁卯桥: 古桥名,现为区域地名(丁卯片区),该处古运河上有现代桥梁(如丁卯桥路桥跨越的是主运河,非此段古运河)。

谷阳桥: 位于谷阳路上。

丹徒闸桥: 位于古运河汇入谏壁大运河主航道之前的节制闸(丹徒闸)上。

需要注意的关键点 区分主运河与古运河: 京杭大运河镇江段(主航道)宽阔,是国家级航道,桥梁高大、跨度大、数量相对少些(主要是干线公路、铁路桥)。市区古运河是历史河道,穿城而过,河道窄,桥梁密集,多为城市道路桥,更具生活气息和历史感。

数量众多: 以上列出的是主要的、知名的桥梁。实际数量更多,尤其在城市支路和古运河段还会有不少小桥。

名称变化与具体位置: 部分桥梁可能有俗称或历史名称,具体位置描述可能随城市发展略有变化。高速公路桥、铁路桥通常没有特别的名字,常以线路名称指代。

谏壁枢纽: 谏壁船闸和谏壁闸桥是京杭大运河上的关键节点,非常重要。

动态变化: 随着城市建设和交通发展,新的桥梁可能会建设,旧的桥梁可能会改造或更名。

Co-Creation Workshop for Road Network Mapping in Karnali, Nepal

Date: 28 March 2024
Title: Planning & Co-Creation Workshop on Mapping Road Network of Karnali
Venue: Care Nepal, Sanepa
Organizer: Open Mapping Hub Asia Pacific
Led By: Rabi Shrestha, Sr. Field Mapping Expert & Prajwal Sharma, Jr. Field Mapping Expert

Project released for remote mapping

The rugged terrain of Nepal’s Karnali Province tells a story of resilience, isolation, and untapped potential. As the only province where road access remains severely limited—particularly in districts like Jumla—the need for a comprehensive and accurate road network is more urgent than ever. With this in mind, a collaborative Planning and Co-Creation Workshop was conducted to collectively address the challenges, gaps, and opportunities for mapping the road network of Karnali through open-source tools and community engagement.

The Nominatim QA tool added a new layer “Suspicious addr:state value”

  • If addr:state is the same addr:province. Depending on country addr:province might not be needed
  • If addr:state is the same as the country code
  • if addr:state is the same as the country name (in any language)

The layer is updated every day.

Give it a go. But not USA and Canada because I was too eager and made many edits today already.

‘ve found myself drawn to a particular challenge: properly mapping the Rhondda Valleys in South Wales. It’s a task that’s proving both fascinating and frustrating in equal measure, but one that’s teaching me invaluable lessons about the complexities of local geography.

My approach has been quite straightforward - I’ve chosen to focus primarily on Ystrad, the area I know most intimately. This isn’t just because it’s familiar territory, but because understanding one place thoroughly seems like the best foundation for expanding outwards. Every quirk I discover, every mapping technique I develop, and every local peculiarity I uncover in Ystrad becomes a tool I can apply to neighbouring areas.

One of the most surprising aspects of this mapping project has been discovering just how much the “official” maps get wrong. I’ve taken to photographing street name signs and house numbers wherever I go - a habit that’s revealed some genuinely baffling discrepancies between reality and what appears on both Ordnance Survey maps and Google Maps.

The most striking example I’ve encountered is Bryn Terrace in Ystrad. This is a very real street, with real houses, real residents, and real post delivered daily. Yet somehow, it’s completely absent from both OS and Google mapping data. Walking down it, photographing the street sign, and checking my GPS coordinates left me questioning whether I was experiencing some sort of cartographic twilight zone. How does an entire street simply not exist in the digital world when it’s so clearly part of the physical one?

The house numbering systems throughout the Rhondda have provided another source of bewilderment. What might seem like straightforward sequential numbering often reveals itself to be anything but. Streets that appear to follow odd/even patterns suddenly throw in a completely out-of-sequence number, or entire ranges seem to have been skipped altogether.

I wanted to share some analysis on a currently undefined part of the PWG Schema (Silver Tier specifically) that I originally posted on the OSM-US Slack. Note that this was discussed previously on the OSM forum, but the analysis here was conducted independently before reading that to.

The key question here: What footway= type, other tags and geometry (separate way from the incoming sidewalk or not) should be specified for the connector ways between the sidewalk centerline and curb nodes?

Currently, the page states only “highway=? + ?=?”; its hard to see how highway= could be anything but https://wiki.openstreetmap.org/wiki/Tag:highway=footway as nothing else seems more suitable and inventing a new highway type would be a major backward-compat break for little benefit; therefore, the decision then would be what https://wiki.openstreetmap.org/wiki/Key:footway tag to use.

原先要在 COSCUP 2025 時講一場,但由於演講場數夠就不佔時段。後來在中研院人社中心的演講有幾頁講 Overture PO 狀況。

信心指數沒有參考性可言。

你會批評 OpenStreetMap 資料的狀況,Overture 也會發生,並沒有神奇藥芳能避免。Overture POI 整體狀況,由於也是群眾編輯機制產生,因此 OpenStreetMap 會發生的問題,Overture POI 也會出現,例如資料過時,新的店家與舊的店家在同一地址都存在 Overture POI 資料集。

個人曾熱衷 Facebook Place Editor,修掉不少不正經的打卡點,如空姐的大腿等。如今 Place Editor 社群散掉了,沒什麼人在修正了。

地址對,圖徵在空照圖像,Overture POI 可能是正確的。不少台北的 POI 點預設點位置常出現在舊莊山區,好像選擇台北的預設位置。

至於對圖客來說,Overture 有用嗎?我覺得如果剛好 Overture POI 是正確的,那就可以複製其資訊過來。

Some websites allow users to post content with links to other sites and have previews for these links displayed alongside with the posts. Those are typically social media sites, and we’ll refer to them as “social media” in this diary entry. Examples of such sites include: - forums based on Discourse, particularly OpenStreetMap Community Forum - microblogging platforms based on Mastodon, particularly en.osm.town

There are many more of course, with some more widely known examples, such as Facebook and Twitter. We’re primarily interested in the listed above because they are directly related to OpenStreetMap.

A preview usually includes a page title followed by a longer description and an image. Typically when a submitter makes a post with a link, the social media site runs a bot to download the linked web page and scan it for metadata. The metadata usually includes textual attributes and links to preview images. The bot then downloads the images and assembles the final preview to be shown to other users.

Metadata

Here we’re interested in previews of pages on the OpenStreetMap website. Usually the links someone posts are to pages of map locations, editable osm elements (nodes, ways and relations), changesets and diary entries. All of those pages include metadata in one of the formats suitable to generate previews, The Open Graph protocol. The Open Graph metadata consists of several <meta> html elements inside the web page <head>.

The degree to which metadata on OpenStreetMap website pages allows generation of a useful previews however varies. Metadata on diary pages is usually sufficient to build reasonable previews. As an example, we can look at the html source of this diary entry:

Following a suggestion by @andygol, I decided to refresh the Highway Tag Usage Scheme used by the Ukrainian OSM community. The original work on this scheme began back in 2013 — see the discussion in the Highways of Ukraine topic. I’d like to share the progress made so far and invite the community to contribute further improvements.

분리수거함 위에 지붕이 있는 경우는 어떻게 편집해야 하나요? https://ifh.cc/v-bFfdNa 여러 재질에 따른 분리수거함들과 그 위에 지붕이 있습니다. 일단은 저는 분리수거함 유형의 점을 만들고 지붕 크기만큼 지붕을 그렸습니다. (다음 지도는 본인이 직접 찍은 사진안 분리수거함의 위치입니다. 분리수거함과 지붕 옆에도 초록색 대형 일반쓰레기 수거함이 있습니다)

F4 map에서는 지붕 모양 hipped-and-gabled가 mansard로 표현됩니다. 왜 그런 건가요? F4 map에서 경복궁 대다수의 지붕 모양이 실제로 OSM에서 태그된 hipped-and-gabled가 아닙니다. 때문에 중국 자금성의 지붕 모양은 hipped-and-gabled가 아니라 지붕의 모양의 조각들을 따로따로 생성한 것 같습니다.

There has been a recent surge of interest in mapping walking infrastructure in Melbourne. This is very exciting because many parts have been lacking for a long time.

I have been adding some things piecemeal over the years. Recently I have made a more concerted effort to get footpath and crossing data into the Map. Several other users have been doing a huge amount to make this happen.

Here I wanted to briefly share a summary of my approach to mapping these footpaths and crossings. As is custom for OSM, this is not prescriptive at all; just a description of how I am approaching this task. It is based on consistency of edits and consistency with existing and new data.

Footpaths

https://wiki.openstreetmap.org/wiki/Tag:highway=footway
https://wiki.openstreetmap.org/wiki/Tag:footway=sidewalk

I am also including the surface where known. Most footpaths are built of concrete, especially in older suburbs. The next most common would be asphalt, but there are still some unpaved footpaths - even in built-up areas. I think this is important to include for accessibility and route planning.

https://wiki.openstreetmap.org/wiki/Tag:surface=concrete

One important aspect here is that I am mapping footpath ways separately to the crossing ways. Which brings us to…

Crossings

https://wiki.openstreetmap.org/wiki/Tag:highway=crossing
https://wiki.openstreetmap.org/wiki/Key:crossing
https://wiki.openstreetmap.org/wiki/Key:crossing:island
https://wiki.openstreetmap.org/wiki/Key:crossing:markings

Here is an example of a simple T-intersection that shows my general approach to mapping ways for footpaths and crossings separately.

タスポが使えるたばこ自販機はhttps://wiki.openstreetmap.org/wiki/Tag:authentication:taspo=yesとタグ付けしてみることにしました。運転免許証、マイナンバーカード、パスポートで年齢確認をする自販機はそれぞれhttps://wiki.openstreetmap.org/wiki/Tag:authentication:JP:driving_licence=yes, https://wiki.openstreetmap.org/wiki/Tag:authentication:JP:individual_number_card=yes, https://wiki.openstreetmap.org/wiki/Tag:authentication:passport=yesとしてみます。

日本人への通じやすさの点でhttps://wiki.openstreetmap.org/wiki/Tag:authentication:JP:my_number_card=yesとも迷いましたが、どうも次期デザインのカードでは「マイナンバーカード」の愛称を使うのを止めるかもという話もでていますので。

In Japan, when you buy tobaccos from a vending machine, you first have to prove that you are 20+ years old. Since 2008, The Japan Tobacconist Federation has been issuing “taspo” smart cards to adult smokers. You can apply these cards to cigarettes vending machines to activate them. Back in 2008, 97% of the vending machines supported taspo for age verification.

Due to technical limitations, taspo system was announced to be shut down in March, 2026, and some vending machines are now retrofitted with new age verification modules that accept a driver’s license card, “My Number Card” (which is officially called Individual Number Card in English), and/or passports (ref: list of government-recognized age verification modules for cigarettes vending machines).

I started to tag taspo-compatible vending machines with https://wiki.openstreetmap.org/wiki/Tag:authentication:taspo=yes, and those with the other verification methods with https://wiki.openstreetmap.org/wiki/Tag:authentication:JP:driving_licence=yes, https://wiki.openstreetmap.org/wiki/Tag:authentication:JP:individual_number_card=yes, or https://wiki.openstreetmap.org/wiki/Tag:authentication:passport=yes, respectively.
