Well, I finally got around to trying to undelete the bit of trail in Redwood National Park between Tall Trees and Emerald Ridge, which didn’t take long because I’d already done the hard bit of finding which way that was by finding the deletion changeset. Unfortunately, there’s a lot of things in this area that nag at me. For instance, while I was (not) discovering if there was any reason the trail was deleted, I sorted out the nag about getting the seasonal bridges correctly tags for that attribute. Maybe. It could be “seasonal=summer/autumn” (used on the bridges) or “seasonal=dry_season” used on the trail. Does dry season start when the rains end or when the creek starts to get low too? Because that creek stays high into the dry, making summer/autumn possibly more accurate. Dry/wet season also can require some lookup. If I saw something was “wet_season” in the southwest US deserts, a few years ago I’d expect that means winter, but now I know it might actually mean July and August, when the monsoonal moisture comes through, but when the southwest US coast I grew up on has average monthly rainfall of 0.04 inches.

Most generous with the naggings are the “Orick Horse Trails”, a stacked set of loops built for horseback riding on the west side of Redwood Creek. They are built from good gravel service roads still in use by the park and old tracks decaying back to trail and a bit of trail too. Mostly it’s roads the public can’t drive. Before getting on with the subject of this entry, I had to deal with some really boneheaded stuff I’d done when getting them mapped at all some 2 years ago. Some of it is so boneheaded, it probably needs a content warning if any mappers are actually reading this. In one instance I apparently added in tiger: tags. Sure, if you don’t understand a tag, don’t delete it. But adding it in could be bad too! But there’s a wiki entry for these and you can delete them if the information is already included (or found inaccurate anyway). Apparently I set some “not:name” values that really should have been “old_name” as, while they are not currently what the trails are called, they are seen on the signs. It’s not wrong, just old. Then there’s the apex bad boneheaded what of setting those service roads to “designated” for vehicles. This was probably meant to convey that designated people could drive them, but that’s not what it means. It means those roads are meant for driving, which is very much wrong! So I had to do some fixing of the boneheaded.

Once I’d cleaned up the stupid I’d done before, and some random tagging of some of the service roads back to track roads plus one path into a track road by a random Amazon employee, I could get back to what was actually bothering me about this trail system constructed of roads. Whose point of view should the map reflect? I have this pie-in-the-sky idea it should be all things to all people. You tag it well with all the things and the land manager can come along and render it one way and get a map showing their roads that only they may use. The public can come along and use a standard renderer and be told there’s these trails you can circle around on. I’m pretty sure that’s not entirely wrong an impression, either. Answer: you don’t have to chose. Everyone gets their viewpoint.

How I get there, it seems at first glance, is to say it’s a road if I see a road. When it’s good gravel I would drive in my Scion if I had the key, it’s a road. These service roads are not all good, but most are. Land manager sees road including being able to drive it. I see road, which is a different experience to hike, but I can’t drive it. So I concluded mark it as a road. They need to be distinguished for the actual track roads in the area, some of which have been removed, some are removing themselves without help. That’s easy, because they’re service roads. They access bits of the National Park by employees.

But there’s problems with this. It ends up hiding the loops of trail. Those attributes that can be applied to paths certainly are discouraged from application to service roads (or track roads) in iD. And what kind is it? General access Park Service employees, which doesn’t seem to be a sort generally. It’s driveway and emergency services and such. If none of these fit, maybe you should be looking for a better tag, like highway=path, the wiki says, hinting that maybe my point of view should be it’s a trail, not a road.

The mountain bikers, who happen to be excluded from this bit of horse trail although generally allowed on horse trail in the area, certainly like to view this sort of thing as trail. It’s a “two track” as opposed to a “one track”, although they really are good roads and one very wide track. It’s talked about as trail.

It’s not really that rare a situation. The Arcata Community Forest has a collection of service roads and trails that the public’s trails follow. When I hiked in regional parks in the San Francisco Bay area, I’ve even seen signs warning me that (gasp!) the trail I was on was about to get too narrow for emergency vehicles, presumably so I know it’s a bad idea to settle into having a heart attack further along. These places do tend to mark it all as trails (highway=path).

So I’ve let go of my point of view it’s a road because someone can drive it. Diverted the idea that the land manager sees it as a road. I’ve changed things to highway=path so it’s all trails, then marked the road areas as 3 meters wide. And I suppose there’s a certain point of view that the land manager is perfectly capable of driving trails that are wider than the vehicle, so maybe it still preserves that all things to all people once it’s got enough tagging idea.

And it nicely distinguishes the trails from the leftover track roads, which should be treated with suspicion in this area. Although I know one that’s nice and I didn’t notice any “no access” signs on it.

Oh, yeah, and then I applied some lifecycle tags. See above about track roads getting removed and removing themselves. A removed:highway where I was actually looking for the thing to be sure I went the right way and never saw it seems sensible. A disused:highway where the trail leaves maintained road and no one but animals has been on the rest has a bit of logic. However, that seems to leave them unrendered. Whatever for the removed/overgrown one you can’t see, but the disused one is now a very distinct invitation for a wrong turn. I mean, there’s a line of rocks across the road and it gets distinctly dirtier, but there are people who can miss those clues. It would be nice if they knew ahead of time they are coming to a junction. “Will not confuse existing applications.” says the wiki. Um, the fact that it isn’t in prime shape doesn’t mean that track road doesn’t need to be rendered for walkers. If disused:highway means it doesn’t render, that qualifies as confusing existing applications. (Well, from my point of view.)

I also went and tried to improve Elam Camp and mark the trailhead. (I was sure I marked the trailhead when I hiked the levees…) The camp includes a corral. I’ve searched for how to tag these and only got one forum post asking about it. They were actually describing an arena and got answers that might do well for the sort of corral that cows and sheep get rounded up into. It doesn’t seem quite right for the little boxes for keeping stock in temporarily at camps and trailheads like the one at Elam.

Oh, the Redwood Creek levees in Orick… I should mark them as trail too? They are built by Army Corp of Engineers. The county has some responsibilities to them. The park service maintains them for walking, at least that’s what the ranger I talked to claimed. Also, no dogs, no matter what you see people actually doing.


Dear community,

anyone has an idea where to find shape files from Latam/Peru? Best wishes and hugs, Anne

Hello community. While I was mapping, I noticed there are not many electrical charging stations yet on OSM. Since the world is fighting to lower the carbon emissions, and electrical vehicles are bought in high demand.

We should not forget to add public electric charging stations on the maps. It can help a lot to be the first all in one service that you not need to install another centralized app for finding your nearest charging station.
@OSM user diaries EN 🇬🇧 Yes, it's important. Also, we should not forget to ask politicians for better public transport, the stops are already in the map and hopefully more will emerge to be added.

Assessing the quality of electric vehicle charging station data (with a specific focus on the "capacity" tag)














Today, I spent the day working on my Open Street Mapping project. Specifically, I was focused on using Leaflet mapping for sports team transport management. This project is very important to me, as I believe that it will make a huge difference in the way that sports teams are able to travel to their various events.

First, I spent some time exploring the different features of Open Street Mapping, and learning how to use Leaflet to create interactive maps. I was amazed at how much data is available on Open Street Mapping - everything from street names to building outlines to points of interest.

Next, I began to work on my project in earnest. I started by creating a map of the area where the sports teams are located, and then began to add in the locations of all the different sports facilities and venues where they might need to travel to. I also added in information about the different modes of transportation that the teams might use - everything from buses to trains to airplanes.

As I worked, I was struck by how much easier this project was making things for the sports teams. With this interactive map, they will be able to quickly and easily see the best routes to take to their various events, and will be able to avoid traffic and other delays. They will also be able to see all of the different transportation options that are available to them, and will be able to choose the one that is most convenient and cost-effective.

Overall, I am very excited about this project and the potential impact that it could have. I am looking forward to continuing to work on it, and to seeing the ways in which it will make a difference in the lives of sports teams and their fans.

2023, here I am and still going strong. December 2021 Kumbirai Matingo just posted in a WhatsApp Group, ‘Anyone interested in OSM, please inbox’. I didn’t know what OpenStreetMap was or what it was all about but I was keen. I honestly wanted an activity to take me away from the boredom of staying at home hoping that the COVID-19 infection rate would decrease and go back to school. There I was in OSM_Zimbabwe steering committee not sure what OpenStreetMap was.

Fortunately in January 2022, Zim was hosting the Africa Monthly Mapathon. 28 January 2022 the first day I added a feature on the OpenStreetMap, Mutasa District Zimbabwe. Thanks to @Last Mufoya. ##to be continued



Mein Weg zu OSM


Der nicht aktuelle Stand der OSM-Karte im Rahmen des Ausbaus der (Eisenbahn) S-Bahnlinie 13 (S 13) von Troisdorf nach Bonn-Oberkassel motivierte mich im Mai 2020 bei Openstreetmap aktiv zu werden. Der Bonner OSM-Stammtisch, der sich einmal im Monat trifft (diskutieren führt oft schneller zur Erkenntnis), hat mir beim Einstieg in das Mappen geholfen. Er ist auch heute noch eine gute Unterstützung

Aktivitäten


Bei verschiedenen Mappings fiel mir auf, dass bei Eisenbahnweichen oft das Tag railway=switch fehlte. Ich stellte mich der Herausforderung, die entsprechenden Node zu finden: Mit Overpass-Turbo wurden die Eisenbahnstrecken selektiert, mit einer Datenbankanwendung die “verdächtigen” Node’s identifiziert, als Overpass-Query in die Zwischenablage exportiert und in der Karte markiert. Die Entwicklung nahm einige Monate in Anspruch. Das Know-how als Dipl.-Ing. der Elektrotechnik mit Schwerpunkt Datenverarbeitung und viel Erfahrung in der Basic-Programmierung halfen. In den DACH-Ländern sollte es keine ungetaggten Eisenbahnweichen geben.

Die nächste Herausforderung bestand darin, die Daten dieser Weichen zu ergänzen. Dabei ist es hilfreich, wenn die Daten symbolisch dargestellt werden. Ein entsprechender MAPCSS-Stil musste her! Dieser sollte die Konfiguration der Weichen und wesentliche Daten darstellen.

Weitere MAPCSS Styles helfen, die Richtung des OSM-Weges und die Geschwindigkeiten anzuzeigen.

Zur Zeit arbeite ich an einem Style für die Darstellung von Eisenbahnsignalen.

JURD’S LAKE Woodland vestiges of the picturesque

Jurd’s Lake was part of the picturesque grounds of Weston Grove House, the former estate of Southampton MP William Chamberlayne in the 19th Century.

Today it is an area of established woodland, with pleasant flowery glades to explore. You may even find broad-leaved helleborine during the early summer.

The small lake and reed beds are a unique habitat. Willow warblers have previously nested here. Through careful landscape managernent a variety of butterflies can be found including purple hairstreak, small skipper and six spot burnet moth.

Himalayan balsam is widely found in the area, spread along the stream. The seed heads explode firing their seeds distances of over 20 feet. Although it looks attractive the fast-growing plant competes with native species and the shallow roots errode the stream bank.

SPECIES TO LOOK OUT FOR • Broad-leaved helleborine (ochid) • Purple hairstreak (butterfly) • Six spot burnet (moth)

Did You Know? Not all moths fly at night. There are several day flying moths including thesiz spot burnet moth.
