I supported my Chapter members with internet data subscription through the help of Mr. Victor Sunday.

I am a co-founder of Oyomappersteam of Uniquemappers network Nigeria. I have trained participants on Missing Map and how to use id editor to map in Open Street Map.

This is my first journal entry on OSM diary. Exciting. Alright, RTK GNSS units are amazing. You can use them in so many different applications, both professional and hobbyist (try doing a quick search on your favourite search engine for example applications)… but they are expensive.

This is how you DIY your own real RTK! You will need to have some knowledge of bash, python, the fundamentals of GNSS, and some interest in troubleshooting.

You will need

1. Two U-blox ZED-F9P GNSS receivers. This is the module behind the processing. You can configure this in many ways, i.e., using a board of your choice. I will be using an ArduSimple board.
2. A radio module. This will be used to communicate between the rover and base over some distance.
3. Power supply. You can use a power bank here.
4. A Raspberry Pi. I will be using a Raspberry Pi Zero W. You can use any device given that it is capable of connecting to a WiFi network.
5. Jumper cables. Male to male and female to female.
6. OTG cables.
7. USB A cables and maybe USB C cables depending on the type of Raspberry Pi you will be using and the type of smartphone you will have.
8. An android smartphone. …we are almost done with the list…
9. An SD card.
10. Two multi-band antennas.

Last, I should mention that this project will be considerably cheaper than the commercially available options. More on this in the coming sections. I will detail how to make the connections to all the devices and maybe the software setup.

Hello everyone.

Recently, I’ve been trying to map National Recreation Trails in OSM. the NRT program will designate a ‘system’ as a national recreation trail, generally meaning all of the trails within a park or other public land.

I want to represent this on the map, but it seems to be beyond the scope of the type=route relations.

I’ve been considering using this: osm.wiki/Relation:network to try and represent these, but I ran into problems with this as well. I tried interpreting the documentation, but it was written so confusingly that I could not understand how to use this relation on the map at all. I asked on the talk page, but I’m still confused on the meaning of this relation.

Additionally, there are National Recreation Trails designated to places serving ATVs or ORVs. I don’t know if this is some redneck thing that the Europeans don’t have or what, but there was no documented tag for ATV or ORV paths on the wiki. so I also created the page osm.wiki/Tag:route%3Datv. I’ve been working on expanding this page as well.

Right now I’m using type=route for these system NRTs, but I feel that it’s probably incorrect and I’d love input from others.

Thanks, SherbetS

Hi everyone, my name is Tareq Al-Ahdal. I am a computer science undergraduate student at Universiti Teknologi Malaysia. Recently, I got accepted into Google Summer of Code 2022 as an open source contributor with OpenStreetMap. I will work this summer on enhancing Nominatim: OpenStreetMap’s geocoding software that enables us to search and find location addresses based on their names and vice versa.

Nominatim is currently using a computed importance value to rank the search results based on the location’s perceived importance. This importance value is derived from the popularity of the Wikipedia article of each location. However, not every location on earth has its own Wikipedia article. As a result, the locations that do not have their own Wikipedia articles will not have an importance value, thereby the ranking of the search results, in that case, is deemed inaccurate. OpenStreetMap has data regarding the number of times users accessed each location on the map. This data is a good indicator of how popular a place is. The aim of my work is to integrate this data into Nominam’s computation of the importance value so that the search results become more accurate which will help the users find the correct places that they are looking for in less time.

I will use this diary to keep you updated about my work. Please feel free to reach out if you have any questions regarding my work or anything else you have in mind.

Microsoft released a machine-generated dataset of building footprints for the United States some years ago. The footprints are derived from aerial imagery. This works well, most of the time. Where you run into problems is in rural areas, especially where there’s natural features and topography that throws the machine learning off. Then the machine starts to think all kinds of things are buildings:

Let’s add the Grande Anello Di Arquata bike route uploaded by user Carlitos2502.

A number of transit agencies in the greater Baltimore region have overlapping service areas, and as a result some stops are shared between operators and/or networks. Typically what this looks like is multiple signs will be fixed to the same post for the different services, and usually the stop will have a different reference number within the systems it serves. If there is a shelter, it is operated by just one of the agencies that uses the stop.

Locally, the Maryland Transit Administration (MTA) stops are the most thoroughly mapped, and functions as the “primary” operator for the region, with connecting agencies often functioning as supplements to it rather than alternatives. In auditing the bus stop information on the map, I had initially thought adding shared stop information to a highway=bus_stop node would involve using operator namespaces like ref:MTA= so that it is clear which agency uses that stop number. The distinction between a shared stop node and two different stop nodes for overlapping services seems like an important one, as in some cases an overlapping service can have a stop very close to another rather than sharing one. This can make a difference in the logistics of connecting between services or assessing some of the finer details of bus stop placement.

The OpenStreetMap Taiwan Community (OSMTW) is pleased to announce that it has secured an alliance grant from the Wikimedia Foundation, which has been used to purchase two Insta360 One X2 cameras with accessories, and to support related workshops scheduled from March 2022 until February 2023. OSMTW is dedicated to organising at least six street-view expeditions and six edit workshops. OSMTW members begin their journey to terra incognita of street-view by self-driving and documenting with the 360-degree camera on the rooftop. Afterwards, members will enhance OpenStreetMap data and upload photos to the Wikimedia Commons, a multimedia repository, with the post-edited expedition media.

OSMTW initiated the 1st preflight workshop on March 19, 2022, at the MozTW space in Taipei, following the maiden street-view expedition on April 24, 2022. Departing from Yangbei Redevelopment Zone (央北重劃區), the 11-people expedition team head for multiple locations in 4 vehicles, including Keelung, Jinshan, and Wanli, and recorded the sections of National Highway No. 3 having insufficient street view data. The team dropped by at the Xiandong Tunnel (仙洞隧道) to take photos at both entrances since the tunnel is currently inaccessible to the public.

Next, the team is split into two, bound for Xiandongyan (Deity’s cave/ 仙洞巖) and the Sprial Ramp (迴車塔). Xiandongyan is a Buddhist temple in a sea cave with designated Cultural Landscape status; however, the outcome is somewhat disappointing due to poor indoor illumination. The latter is a unique artificial driveway slope in Taiwan. The team later rendezvoused at the Dawulun Fishing Harbor (大武崙漁港) for replenishments; crowds were observed on the beaches even under the COVID-19 outbreak.

THIS IS NOT A PROPOSAL.

In most Yangtze Delta cities, buses usually operate in three separate networks: City Buses (城市公交), Suburban Buses (城乡公交) and Town-Village Buses (镇村公交). Some of those do operate outside the city boundaries, which are classified as Intercity Buses (毗邻公交), they can also be a City Bus Line, a Suburban Bus Line or a Town-Village Bus Line.

There exist a group of enthusiasts who spend their weekends from one city to another city purely by buses or subway lines, such a route is possible by benefiting from the tremendously complicated and connected bus network of Yangtze Delta Cities. I’m one of those enthusiasts who usually spend my entire weekend on buses and subway lines from city to city, as such I do exactly have “local knowledge” that I could benefit others if I can draw these lines on OpenStreetMap. In such a circumstance I figured out that there isn’t a proper way to mark the type of a bus line. After a long discussion with some of the experienced users, I decided to add an unofficial tag network:route:bus:type to tackle this special issue around Yangtze Delta.

For values of network:route:bus:type I would temporary provide city, urban, suburban, town, intercity as five valid options, further extension is possible.

• city (城市公交), suburban (城乡公交), town (镇村公交) options are used when 3-level bus networks exist in such an area.
• urban (市域公交) option is used when there’s only a single bus network, this option should not use on it’s own since you don’t really need it.
• intercity (毗邻公交) option is used for bus routes that operate outside the city boundary limit, this is a optional tag and should be used with the other options.

I was involved in mobilisation and signing up new members to OSM and participated in a mapathon titled “#mapmyvillage”.

One of the things that note-viewer does is showing notes on a map. They are displayed as markers which we can click to find notes in the table. Map markers show us locations and statuses of notes, the rest of note details can be found in the table. But we can dig deeper into these details. From the last diary entry we know that note-viewer looks for links to osm elements inside note comments. When clicked these links display their linked element on the map. That shows us the element geometry, but now we may want to see more details about the element. The map is displayed using Leaflet library¹ which supports adding popups to various items that are shown over the base layer. A popup seems like an appropriate place to show the element version, changeset, last editing user and tags.

What’s the best way for us to implement these popups? If we just bind the popup (layer.bindPopup()) to the element geometry on the map, the user would have to click the element for the popup to show up. Sometimes that’s not very convenient to do because of note markers covering the geometry. To make things easier we can open the popup right away (layer.openPopup()) when the element link is clicked. But that’s not the only thing that needs to happen at that moment, and we may find ourselves struggling a bit with Leaflet. Obviously the linked element may be outside the current map view and we need to pan and zoom to it (map.panTo(), map.flyTo() or others). Opening the popup could have done part of this job because by default the map pans to the opened popup. That still doesn’t take care of zooming. But you may think so what, just let the user zoom to the tip of the popup to find the element on the map.
