I recently wrote about using the JOSM Conflation plugin to identify traffic lights in OSM missing from the TfNSW’s open data.

Now TfNSW have released some data on enforcement cameras, so I’ll try again using JOSM.

1. Download the CSV data
2. Rename the Lat (1) and Long (1) headers to Latitude and Longitude. 3 Open the CSVs in JOSM.
3. Select all the imported nodes from the Fixed Speed Cameras and replace all the tags with highway=speed_camera
4. In JOSM, download existing speed cameras as a new layer from overpass with ((type:node and highway=speed_camera) or (type:relation and enforcement=maxspeed)) in "NSW, AU"

5. Conflate

6. Select all the nodes from Red Light Speed Cameras, and replace all the tags with highway=speed_camera
7. Conflate again.

I have created 3 or 4 blogs over the last 15 years. Unfortunately I lost interest after the first entry and never made a second.

Maybe this will be different?

Recently, I came across an OpenStreetMap changeset with “Review requested” tag. The change was addition of a bus route relation in Istanbul, by Alikam.

I navigated to IETT’s (the governing body of Istanbul’s transport network) website to cross reference the route maps. I noticed that there were some minor differences between the route on IETT’s website and Alikam’s version on OSM. The route wasn’t following the exact roads. This wasn’t a major issue but I still commented on the changeset, mentioning discrepancies between the two versions. Alikam, who’s an urban planning student and OSM contributor with a priority on transport network, wrote back a few hours later to tell that the major junction at that point had been rebuilt as part of the construction of a new underground line. Apparently due to that major change in the highway infrastructure, the bus route have been changed as well. But as of this writing, IETT haven’t updated their website to reflect the relevant changes. Meanwhile, thanks to Alikam and all the contributors like them, OpenStreetMap is more up to date than the official source for Istanbul’s transport network.

This wasn’t a major issue, but it makes one think if there are other cases where people rely on the official/private/closed data and left stranded or were late to a very important meeting (I’ll give you a clue, answer is yes).

So kudos to Alikam and all those great contributors of this wonderful open community.

At 10:30 am 9/18/2020 I joined OpenStreet, looking for a volunteer opportunity as I approach retirement.

At OpenStreetMap related conferences, I always look forward to the technical talks so that I can learn and improve my mapping skills. Equally important are the community building talks, this gives me great perspective on how mapping communities are nurtured around the world especially for countries whom I share the local context and culture.

For a crowdsourcing online community like us, however, community stories are often relegated as side tracks or lightning talks in a smaller room. If we truly believe that the strength of OSM is the community, these stories should be front and center in our interactions especially during conferences.

This is what we tried to do within our own community events. Here are two events I helped co-organized that is aimed at increasing the audience listening to our community stories.

State of the [country] talks are plenary sessions in the State of the Map Asia in 2016.

We decided that all country status reports at SoTM-Asia in 2016 will be reported to the plenary. This ensures that everyone hear and learn how each country are building their own community.

Tried to upload edits in newest JOSM but validation crashed the program with out of memory. Allocated 4GB, but JOSM said gib more clay, so added 2GB more. Still failed. All six cores of my (uber powerful FX) were pegged at 100%, eventually I had to kill java. Tried with the previous version with the same result. Finally, after a few restarts, I uploaded my edits without any validation checking. That’s a first for me.

It’s kinda strange. I only got about 800 objects to upload and it failed. I regularly uploaded more than that, almost double, successfully while also fixing all the validation flags that I can fix. The only thing different that I can think of is that I used the remote control feature for fixing a couple of notes from main openstreetmap website.

Anyways… happy mapping!

Hi! Thanks for your recent fixes!

I have a question to you as a pilot: I touched up many airports in OSM, and I was always wondering: how do real pilots use OSM if at all, what is helpful to pilots and people working airports, are there certain details that should not be posted due to security considerations, any details that are available on commercial maps that are just confusing when they present in osm?..

Would you be willing to write about this, maybe in an OSM diary entry?

Thanks!

---

When considering airports, you must put into account security awareness. All mappers should make sure when mapping an airport to not change any fencing prior to your edits unless it is because of new satellite imagery. Also, DO NOT publish info about codes or key locations. This can cause serious problems. Pilots do not use OSM because of the lack of measurements as pilots need them.

oh my god there are so many garages in my town. its packed enough that most houses dont have attached garages but most have space in the back of the property to put one along a side road. twice the zone work as any other suburban area. god.

edit: just realized these diaries get put into a public feed. a lot are more organized than stupid ramblings like this, or serve as announcements. think ‘journals’ or ‘notes’ would be a more fitting term if that’s the intended use for this. I read ‘diary’ and assumed it was just for writing whatever

Mapping

For a good part of a year I have been marking street level imagery instead of Aerial Imagery.

I though Aerial Imagery was zoomed out a lot and Street Level imagery was close to the ground. Sorry.

If you are a user of OsmAnd Maps for iOS, you might have to refrain from using the current version (3.14) to edit OSM POIs. I just figured out that, after editing a bunch of POI opening hours in my suburb, the changeset also affected the locations of the POIs, even though I did not touch that.

It looks like the editor rounds the coordinates of the POIs to 6 significant figures, which might look like a move of only a few meters on the map, but the changes get more drastic as you move away from the equator and the meridian. I suspect people editing in Oceania and East Asia will see more obvious changes.

In this picture, from data in eastern so-called Australia, the arrowheads roughly show where the POIs should be, and the green line shows the longitude where they were moved:

It’s very silly question but I like to describe my opinion. Once upon a time I could’t know how to use map let alone edit. When I stated my journey with OSM tried to add my own locality’s data first as a beginner mapper all of us do it like me. There are lots of mapping organization in the whole world but openStreetMap is totally different from them.

We can’t edit all the mapping sites but osm gives us this opportunity to edit in here. The community is always being ahead for humanitarian works instead of business purpose use. May some guys are using for business purpose but humanitarian action is first priority.

I would like describe myself an OSM Mapper. Happy Mapping.

What are these diaries for I wonder?

Today was my first proper contribution to OSM. I made over 100 edits using the StreetComplete Android app plus a couple of manual edits using the website. For a while at least, this is going to be a fun excuse to get some exercise.

My plan, I think, is to…

• Learn more about the philosophy behind OSM (I’m interested in the cycle, transport and humanitarian maps)
• Get a bit more familiar with the tools and mapping
• Maybe try to come up with some specific ways to contribute that interest me. I’d like to add more of the BTN BikeShare hubs for starters.

My goal outside OSM is to learn QGIS and more generally how to make maps, for Wikipedia but also for my own personal interest.

We’ll see.

Kind of a noisy campground

Have you ever thought “Gee I wonder if you took #OpenStreetMap data for North America, and coloured the image based on the distance to the nearest building?”

No? What kind of person are you?

A few days ago I wrote about my plans to map the Mountains-to-Sea Trail, putting each segment into its own relation (and then putting all relations into the main MtS Trail relation). This has now been completed!

There are a few more things that need to happen to complete this trail.

• Alternate routes need to be added.
• Drinking water, toilets, and other points of interest need to be mapped along the trail.
• Roadways need to be aligned (trails look pretty good, I think).

It will definitely take a while to complete these tasks but perhaps if done by section it will make it a slightly easier to keep track of the tasks.
