This is a cross-post from my blog

I have always been excited about the opportunities open street level imagery (SLI) offers to OSM. I helped launch OpenStreetView (now Kartaview) back when I worked at Telenav and was an early contributor to Mapillary as well. Recently, I’ve had the opportunity to work more closely with the great folks at Mapillary. This re-kindled my excitement for SLI & OSM! Good things are rolling out and will continue to roll out in 2023, so stay tuned! The Mapillary blog is the best source for announcements.

Most recently, Mapillary added support for 360° video upload to their desktop uploader and the CLI tools! This is great news for anyone with a supported camera, like the GoPro MAX. I happen to have one of those so time to try it out!

The Mapillary help pages include great and authoritative guides on using 360° cameras including specific instructions for using the GoPro MAX. This post is just me summarizing my own experience.

Preparing

You only need to do these steps once.

  1. Get the latest version of the Mapillary Desktop Uploader available for Windows, Linux and MacOS.
  2. Install the Uploader onto your computer.
  3. Open the Uploader and log into your Mapillary account.

Capturing

  1. Make sure your GoPro MAX is fully charged and set to 360° video. I used 5.6k and 30fps1.

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.

BRAZIL - SÃO SEBASTIÃO - (SP) - AREAS AFFECTED BY FLOODS, FLOODS AND LANDSIDES ON FEBRUARY 19, 2023 Brazil On February 19, 2023, the cities of the North Coast of São Paulo were hit by more than 600 mm of rain in 24 hours, with São Sebastião being the most affected and with the highest number of deaths so far.

The neighborhoods that were most impacted are: Baleia, Barra do Sahy, Boiçucanga, Camburi and Juquehy.

Mapping in the City of São Sebastião/SP - Brazil will be carried out by beginner and advanced mappers and aims to

DESCRIPTION For this mapping, use the Bing image.

Many buildings are very close but not really touching. Try to map them as closely as possible without allowing them to connect with each other or the streets.

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.

Thought I’d give editing my home town a go again ( have been here before). Please forgive me for any mistakes, it will not have been intentional. I see some issues with POIs for example a police station that doesn’t exist anymore the adjacent firestation is still there with POI. Do I remove the POI or just remove the info attached? When it’s a shop or a former bank I think I probably should remove the info and leave the point….. if anyone has any pointers on where to get guidance on this that would be nice, otherwise I’ll keep looking for guidance!

This year, I promised myself to contribute every day in order to catch my absence since my registration in 2015.

I really enjoy mapping and I take even just 5 min every day to edit in OSM.

Yesterday, I totally thought, I had already mapped. Since we are dealing with electricity on this rainy season (yes, in my city, when it rains, sometimes there is power failure which turns off our wifi :D ). So, I broke my daily activity.

https://github.com/bvl2016/30DayMapChallenge2021/blob/main/maps/OSM_Failure.jpg

I hope for the coming day to contribute more.

PS : don’t know how to import image here :D

Beside national parks, there are form of flora and fauna protections which falls into the category of Nature Reserve.

One example I know by personal experience is sectors of rivers where fishing is forbidden or regulated, usually to protect the ecosystem.

OSM holds the Nature Reserve tag already.

The class of protection is also a good way to describe, but fish reserves are not listed explicitly. Also it seems that is applies to boundaries only.

…research in progress… suggestions are welcome!

If you’re a member of OpenStreetMap U.S., check your inbox and vote in this year’s election for the open seats on the board of directors. There are some familiar names and some new ones, but each of them is well-qualified and eager to serve the community. For the first time in a while, you won’t see my name on there. After four straight years on the board, I’m wrapping things up and stepping aside to let those with fresh energy take the organization forward from here.

Four years ago, when I first ran, the organization had just hired Maggie as our new executive director. We were still transitioning from years of depending on an all-volunteer board to keep the lights on. Putting an on annual conference was enough to keep our hands full. Formal partnerships with other organizations were still a ways off. Did anyone notice we hadn’t officially become a local chapter yet?

I’m writing this entry mainly to say that I intend to put maxspeed tags on a lot more Champaign streets now that I have the information I need to be on pretty firm ground in doing so. That information is in the form of the default (read: non-posted) speed limits on roads in Illinois and Champaign.

First, the Illinois state laws on this. According to the Illinois Vehicle Code the speed limit in urban areas regardless of whether it’s residential, a business district, or an industrial area is 30 MPH unless otherwise posted. In alleys it’s 15 MPH. The one exception is near schools where the limit is 20 MPH, but signs must be posted in those areas.

The Champaign Code of Ordinances is the same with one exception: the university district. Here the unposted speed limit goes down to 25 MPH. If you’re wondering what the definition of that district is, it’s in the definition section but I’ll quote it here since it’s short enough:

University District means that area within the following boundary: Start at University and First, proceed east along University south row line to Wright, proceed south on Wright (extended) along City limit line (located at the back of east curb) to Windsor, proceed west on Windsor along north row line to Neil, proceed north on Neil along east row line to Springfield, proceed east on Springfield along south row line to First, proceed north on First along east row line to beginning.

Keep in mind it does not include the section of the University of Illinois that’s in Urbana. I’m focusing on Champaign so I’ll leave it to you to look up Urbana’s code on this.

The point of all this is that unless a speed limit is otherwise posted or a street or road goes through the University District it’s safe to set maxspeed=30 mph on streets and roads and maxspeed=15 mph on alleys, even without a sign.

Since 06 February when the first earthquake struck Turkey and Syria, more than 6,500 mappers have mobilised to contribute to the response through the creation and improvement of OpenStreetMap data.

On 09 Feb, I wrote a diary post about whether the OSM data being contributed by mappers and validators in Turkey and Syria was helping anybody. This one builds on that theme…

Below is a selection of maps and map products being used by responders that incorporate OpenStreetMap data (gathered through searching data sources on maps and data products on ReliefWeb, the MSF Geo Centre and through what people are reporting on the HOT disaster-mapping slack channel).

I am Austrian and have been working with GIS (Geographic Information Systems) in Vienna until I retired to Ireland in 2020.

I always liked maps and I got interested in OpenStreetMap at some point, recognizing the great potential of it. I also got interested in Irish placenames after moving to a Gaeltacht area on the Dingle Peninsula in County Kerry. During the Covid lockdowns I started some mapping of Irish placenames, but at some point I gave up, as I did not really see an audience for it and found it rather time consuming.

Recently I learned that some people in our the community want to record the Irish names of farmers fields, which until now have been passed on by word only from one generation to the other. But this does not work anymore, and there is fear in the older generation that the names will be lost forever.

When I heard this I suggested to map the fields and their names and did some testing with OpenStreetMap, which worked very well and was much appreciated by members of the community and of CFLT ([Comharchumann Forbartha an Leith Triúigh] (https://www.cflt.ie/)).

I am not only mapping disconnected field areas, but instead I first add field boundaries as barriers with proper tagging (wall, hedge,…) and then build a relation documenting the land use and adding the field name to it. This way it is not only about displaying field names on the map but also adds useful details for navigation and avoiding unnatural and bad looking gaps between landuse areas.

To be able to extract all this data for producing specialized maps for the community using QGIS and also as backup, the features are tagged with a new tag key cflt:category
