The First Boat - Iquitos To The Triple Frontier

The boat from Iquitos was to be our sole concession to relative comfort on the river, foreigners have to pay a higher price for the ferry than locals, but the benefit was to be on the upper deck with more space, and an outside area at the back. There are faster boats doing this stretch of the river, but you are stuck inside the boat the whole time with very limited views of the river. Ours was the middle option between the three day slow boat and the fast service, and finally we were on our way down the Amazon.

Leaving in mid-afternoon we had about 3 hours of daylight left for river watching. The first proper sunset I had seen in Peru lit up the river before dark. And then we had a glorious full moon ahead of the boat, meaning that we had some visibility all night long. The ferry is quite modern and relatively fast, we even had a TV showing Peru playing Chile in a World Cup qualifier.

Iquitos

One more plane, and then the real Amazon journey begins. I think I read somewhere that Iquitos is the largest city in the world that has no road connection to other parts of the country It belongs to. So a plane was the only alternative to seven days on the Rio Ucayali.The plan was to get to Iquitos and leave as soon as we could get a boat, with roughly two weeks left before arrival in Belem at the beginning of December for FOSS4G. and SOTM LATAM. In the end it was to be an overnight stay, there was a ferry leaving the next day for the Triple Frontier shared by Peru, Colombia and Brazil.

TL;DR

Bing imagery in Greater Accra Region is very very old but it continues to be used as the primary reference for adding new data into OpenStreetMap. Esri World Imagery however seems more recent in and better aligned thank Bing.

This diary is a comparison of seleted locations in Accra with new developments that can be clearly seen in Esri World Imagery but not in Bing; one of the reasons not to use Bing as primary reference for adding new data into OpenStreetMap in Accra.

Bing imagery also have some interesting imagery offsets and mosaic problems such as the photo below and around this node.

Patiently awaiting your arrival

Pucallpa

Iquitos wasn’t our first Amazonian destination, before we headed for Pucallpa - located on the Ucayali river much further south. Johnattan has worked there and is also heavily involved in the local OSM group. At one point we even considered starting the Belem boat trip in Pucallpa, the Ucayali combines with the Marañon river way down nearer to Iquitos to form the Peruvian Amazon. But an estimated seven additional days on a boat to Iquitos was a bit too much, another time maybe. I was dealing with the change of atmosphere from the western side of the Andes, it poured with rain shortly after arrival and moving around in tuk tuk style transport to get anywhere made it feel like a different country.

Huaraz

We were in Huaraz for an event on climate justice organised by the South American Wikimedia community. A very interesting event, my first with Wikimedia, and with a particular emphasis on giving a voice to the representatives of indigenous communities. Including a forum involving Saul Luciano who took the German energy giant RWE to court in a landmark case for their contribution to emissions that help to melt the glaciers that in turn threatens a deadly lagoon overflow for those living in the flood path below. He said he had never seen the glaciers recede as much as they had this year. OSM got some time and mentions at the event, although it got me thinking about how communities with so much in common seem to live separate existences.

And we did some mapping, enough to refresh data for the centre of Huaraz. My first Peruvian changesets. As for the nearby mountains, I had taken a tough packing decision to fill valuable rucksack space with my mountain boots and a bit of winter clothing in case I had the chance for a day in the mountains. it didn’t happen, the weather wasn’t kind and the boots haven’t seen any use. Of course the views of snowy peaks had to be fantastic the next day as we flew back to Lima in preparation for moving onwards to Amazonia. A planned presentation/workshop in a Lima university never happened as a strike timed to coincide with the APEC international summit closed the university for three days.

Landing In Lima

There were nervous moments before starting the journey. The terrible drought this year across Amazonia even put the whole project in doubt, we couldn’t be sure that the boats would be running as reports came in of Amazonian towns suffering water shortages. Together with the brutal wildfire season it seemed that we had picked the wrong year, although the real question after 2 consecutive years of drought might be whether there will be better years to come? Hard to believe when I looked at the hydrological data I had loaded for the Amazon basin. At one point I was considering buying a reserve air ticket from Lima to Manaus, which would have been a very disappointing way to do that journey. In the end October brought better news, it rained enough for the boats to run and Johnattan organised a short Peruvian itinerary (including OSM mapping!) which would take us to Iquitos for the first boat down the river. The first of three or four that we would need to get all the way to Belem with an estimated travel time of two weeks.

I landed in Lima on the 5th November and had a couple of days to acclimatise before setting off for the first destination on the trip. Great ceviche in a market stall which the tourist guidebooks will hopefully never discover, and time to see some of the city. Even time to drink a bit too much pisco, but you have to try the local products? Then it was off to Huaraz, located at 3000 metres and lying below the Andean peaks of the Cordillera Blanca. What does this have to do with Amazonia? The mountain chain is where all the debate about the source of the Amazon is focused. You can hardly get more of a landscape contrast than that between the western and eastern sides of the Peruvian Andes. I went up to Huaraz on the bus, and through the desert surrounding Lima then upwards through a semi arid mountainous landscape which differs sharply from the forest to be found on the eastern slopes.

Big River - The Project To Go With The Trip

Once I had decided to make the trip down the river I thought it would be interesting and useful to have an Amazonian themed maps and data project. A couple of years ago, in FOSS4G in Florence, I attended a presentation about TerriaMap and it ticked a lot of the boxes for a plan I had to do an open data and maps catalogue for Madrid and possibly other regions of Spain.

I had installed the tool and done some fairly basic experiments - but with the Amazon journey already being booked the focus changed and I embarked on a possibly over ambitious attempt to combine multiple data sources for the whole Amazonia region. That means a significant part of Brazil, Peru, Ecuador, Colombia, Venezuela and Bolivia. The project is online at Big River although for the moment it contains mostly base cartography sourced from national mapping agencies.

A lot of OSM data is in the queue to be loaded, already there in the case of Peru, and the first cross frontier thematic dataset covering the frightening wildfire season of 2024 across the entire Amazonian region is also in the pipeline. There’s a huge amount of open data available and work on the project will continue - but first I have to get down the big river!

How Did I Get Here?

Big River, or how to get to FOSS4G/SOTM LATAM in Belem the slow way. There’s a backstory here, the short version is that 36 years ago - on an extended journey from Costa Rica down to Rio de Janeiro - I tried and failed to get a boat trip down the Amazon from Manaus to Belem and the fine hammock I had bought on the way in Venezuela never got used. In the end I saw very little of the river. Time passed and the regrets faded until they announced that FOSS4G 2024 would be held in Belem.

The announcement got me thinking, obviously this was a chance to try again with at least part of the Amazon. And then, because I’m fairly light on work commitments at the moment, I started thinking that the journey could begin further up river than Manaus. Maybe even in Peru?

So back in April or May I sounded out Johnattan Rupire from the Peruvian OSM community to check whether it was a crazy idea to go to Belem from Iquitos by boat. It is a bit crazy, but it turned out that he was thinking of doing exactly the same trip. And with that, plus quite a bit of internet research on just how many boats we would need to get to make it happen, I got on a plane to Lima in early November.

Thankful to be facilitating the OpenStreetMap Foundation (OSMF) - Local Chapters and Communities Working Group (LCCWG) Sub-committee for OSMF Affiliation Models (wow that’s a long name! 😅 )

✍ Documentation including volunteers list and meeting notes are in the OSM Wiki.

🥡 highlights:

1. 🤝 Last Saturday, we had our first volunteers meetup! About 14 people joined the call and we focused our session in getting to know each, and providing clear guidance and space for questions regarding the sub-committee’s goals, volunteer roles, and what to expect

2. ✈ Today, co-leads meet to get to know each other and to set expectations

• Co-leads expressed their enthusiasm to lead teams and identified support needed (e.g. clarity on role, resources, tasks to undertake, time commitment etc)
• Co-leads are: Pilot (be the leaders), Support (their co-leads and team members), and Engage (facilitate within their team)

Recently, there’s been quite a lot of discussion about the problems with using the tag “highway=path” in the forum. See for example threads here, here, here, here, here, here, here, here, here, here, here, here, here, here, here, here, here, here, here, here and here - and that’s only the last month or so!

It’s not descriptive

On it’s own, “highway=path” doesn’t really say anything other than it’s somehow possible to get from one end to the other. Have a look at the pictures in the wiki - all of those are regularly tagged as “highway=path” in some regions.

There are some really bizarre examples out there. Up the Hillary Step to get to the top of Everest? highway=path. A scuba diving route? highway=path.

While it is possible to add extra tags to say a bit more about the feature being mapped, often this simply isn’t done.

A data consumer (map maker, routing app creator or even just a human deciding whether to go for a walk somewhere) can’t tell what they’re going to find.

It’s impossible to tag the legal situation properly

The idea is that you can tag a path for pedestrians as “highway=path; foot=designated” and one for cyclists as “highway=path; bicycle=designated”.

The problem here is that “foot” and “bicycle” are “access” tags, and these aren’t always “yes” or “no”. Valid values might be “customers”, “destination”, “permissive” amongst others. If the “foot=designated” on a “highway=path” implies “foot=yes”, what should the tagging be if only customers are allowed?

In countries with some form of allemansrätten (much of Scandinavia, some other places in Europe, including Scotland) this is less of an issue. If you know you can go pretty much anywhere you don’t need to explicitly tag “foot=yes” on everything, and tagging “highway=path; foot=designated” isn’t a problem.

I was thinking of sharing my experience and reflection for my second year as an OSMF board member, like I did in my first year, then thought, it would be better and greater to write it with my co-board members.

Together with my 2024 fellow board members, Craig, Dani, Mateusz, Roland and Sarah, we are grateful to share our Collective Board Report for the 2024 Year of the OSMF.

In this collective report, we share and document what happened in 2024, celebrate achievements, be transparent about our challenges, and recommend improvements to progress OSMF mission.

I’d like to also mention the collaborative process and inclusion of diverse perspective that we put in our work together as a Board and documented in this written report.

I love this excerpt from the Collective Power Playbook:

“By working together, we can achieve more and benefit more than alone. Collective power means shared ownership of outcomes, lessening the likelihood of failure and benefit for many rather than the few.”

Personal reflection

When I decided to run for OSMF Board in 2022, my main agenda were to improve representation and ensure that community agenda is at the table. Looking back, I put four focus areas in my manifesto, and shared updates for and shifting prioritization after my first year as board member.

This year, as part of the Board, I focused on the OSMF Membership Campaign, being the Board liaison to the Membership WG, and revising State of the Map (SotM) pages.

Along the road, I went through a major life change and so I needed to deprioritize and shift focus again. I decided not to re-run in the Board, and continue to contribute to the SotM and LCCWG.

My hope for the OSMF is continue to push for gender and geographic representation and inclusive participation in leadership spaces as well as increase transparency and commitment to open collaboration among its board, members and the community.

• Full changelog: https://github.com/zbycz/osmapp/releases/tag/v1.6.0

For those who doesn’t know, OsmAPP is trying to be the one integrated app for everyday use which runs both on web and mobile. It should be as easy to use as Google Maps, but fully open-source with privacy in mind. We still have a way to go, but we are going stellar. 🌠🔥🍾

First we have great news to share – we are thrilled to welcome @Dlurak to the core team! 🎉 His persistence, focus on code quality and dedication to bringing open maps to public earned him a place in project maintainers. In this release he proved himself as a top contributor and also took care of other people’s PR. Thank you @Dlurak! ♥️

Release 1.6.0 sums up almost 3 months of great changes by @kudlav, @amenk, @j9d3it and also from the core team @dlurak, @jvaclavik and @zbycz.

Directions. Finally! 🚶 🚴 🚗 🚀

This was the plan from the beginning of the project. Issue #31 from summer 2021 speaks for itself. The problem was, it seemed too easy. It is not challenging enough to use some API and write a line on the map 😅.

In the end, the challenge was designing the directions form. First trials with expanded Search input were catastrophical and salvation came from AI. The v0 tool by Vercel lets you chat with GPT and get the code in any framework. You can check our results here: https://v0.dev/chat/3MwraSQEqCc

Second challenge were the form interaction and persistence. React is one-way sync by design, and synchronizing the Autocomplete inputs to URL was tricky.

But it went well in the end, and thanks to our valued core team, we got also driving instructions and beatiful start-end markers. And yes, we hear you - there are also open PRs for multiple stops and turn-by-turn navigation. Stay tuned! 🤞 🔮

Big shout out also for @karussell from GraphHopper to proactively offer us bigger limits for API usage. ❤️

SearchBox is becoming omni-box 🔎

As you might know, I’m the main developer of MapComplete. For those who don’t know, MapComplete is an OSM-viewer and editor, where contributors can easily answer questions, add new points and upload pictures from a POI from a cozy website. Instead of showing all data at once, it only shows one items within a single topic, resulting in many thematic maps to choose from.

Four years ago, I started with uploading images to IMGUR, a “free” (paid for by advertisements) image host. They were really permissive at the time, and I got the API up and running in about 15 minutes. For the past four years, they served us well with barely any trouble. They rarely had outages and if there was one, it only lasted a few hours at most.

But it was not meant to last. The first crack in this relationship was a little over a year ago. Igmur changed their terms of use, making clear that they would remove “images that aren’t watched often”. In practice, this was mostly meant to remove NSFW pictures from there platform, but it was a good excuse for us to start backing up all the imgur images linked to from OpenStreetMap.

The next omen was the change of terms. From being very permissive, those went to “please, don’t use IMGUR as your Content Distribution Network”, which pretty much is how MapComplete used IMGUR. Oops. In this forum thread, I wrote “I hope IMGUR wouldn’t notice us before MapComplete made the switch to Panoramax”.

Famous last words.

About a week later, our upload got blocked. Contributors were not able to upload new pictures anymore

As such, Thibault Mol setup a Panoramax instance to be used with MapComplete (thank you very much for this!). I spent quite some time to change MapComplete to support panoramax as backend, making uploads possible again!

This has been notable in the graph by TagHistory for Panoramax: one can notice the graph going steeper during october:

Personal note and acknowledgement

The Open Mapping Women Awards 2024 was inspired by the 𝗦𝘁𝗮𝘁𝗲 𝗼𝗳 𝘁𝗵𝗲 𝗠𝗮𝗽 𝗔𝘀𝗶𝗮 𝟮𝟬𝟮𝟯 𝗖𝗼𝗺𝗺𝘂𝗻𝗶𝘁𝘆 𝗔𝘄𝗮𝗿𝗱𝘀 where we recognized community champions across Asia. Of’course, this would not also be possible without the brains and heart of the wonder HOT Community Working Group members, and the amazing women in our open mapping community.

I would also want to thank my DEI Champion, friend and beb, Mikko Tamura, for instilling in me that why don’t we recognize every nominations? There may be some unsung heroines or leaders we don’t know globally or have just one nomination, but their impact goes beyond that.

I hope we can continue celebrating and recognizing women in our community!

(Note: Took me 8 months to write something about this. But hey, do you know that International Women’s Day (IWD) is celebrate every March 8? And yes, just want to make that connection with 8 month delayed posting lol. Sorry for the very delayed update! 🥹)

Preamble

I have been interested in making “before and after” comparisons of mapping progress for a while. The rich and beautiful OSM-carto style as it appears in standard OSM is a particularly important element of what I wanted to achieve, but it remains quite difficult to render historical map data in this style.

This guide mostly follows the ohsome guide from 2018 but taken further and with updates. Please be aware that I have done little to optimise the workflow so far; this is more of a proof-of-concept at the moment.

I started out mapping in August 2020 and mapped almost exclusively in my old hometown whilst I was stuck there during COVID. I spent a lot of time mapping this area very comprehensively and wanted to visualise my work. Big shoutout to user John Bek who greatly helped with building tracing, which is quite tedious. The Blue Mountains towns of Katoomba, Leura and Wentworth Falls featured are now some of the most comprehensively mapped in Australia.

For some time I’ve been looking after a raster map style that’s designed to be a useful “England and Wales rural pedestrian” map, and also to showcase some of the richness of data that might not be obvious from basic “general” map styles such as the ones on OpenStreetMap.Org.

A goal for some time has been an offline version of that map style. At any useful level of detail that requires different technologies to be used, and the first parts of that - a vector map schema and a web map style - are now available (though not yet available offline).

The online version of that map is available here. It’ll take a couple of seconds to appear.
