The Second Boat -Tabatinga To Manaus

Departure day from Tabatinga and the start of the real adventure. Be here at 8, they told us when we bought the tickets, so here we were not much after that time, but once the people waiting for the fast boat had left there was just a handful of us. I didn’t mind, the early arrivals get the best hammock space and 4 days is a long time to spend in the wrong spot.

The Triple Frontier 3

Monday was a list of things to do, the last day before departure for Manaus. Priority number one was to move from a hostel too far away from the crossing into Tabatinga to one that was almost on the frontier, a pillar 10 metres away from our rooms marked the boundary. A brief stop for breakfast and down to Tabatinga port to buy our boat tickets, again checking out hammocks on the way.

The Triple Frontier 2

Day two in Leticia began with another visit to Tabatinga. It was Sunday and the boat ticket office wasn’t going to be open, but we did need to get our Brazilian entry stamp in our passports, we weren’t going to get on the next boat without that. Remote land borders can often be more difficult to cross than arriving at international airports, but we had no problems here - a couple of questions about the purpose of our visit and it was done.

With the rest of the day free we went back to Leticia and got on a boat to Santa Rosa for the last time on Peruvian territory on this journey. Johnattan was carrying a small drone, and we wanted to do a bit of drone and street level mapping of the island. All of the main points of interest on Santa Rosa are concentrated on a single road, so we mapped our way up from the clutch of restaurants facing Leticia to a midpoint in the village and decided that the heat merited a refreshment stop in a friendly and spacious bar restaurant.

The Triple Frontier

With an eye on our (OSM powered) maps the first surprise on arrival at Santa Rosa was that we were being dropped off on what appeared on the map to be a separate island. Our moto taxi driver explained the reason for this, the drought that had affected so much of Amazonia had also changed the endpoint for a ferry that had been unable to run a few weeks before our arrival. In reality the two islands shown on the map are currently one, with a dip on the muddy track being the only indicator.

The triple frontier is a curious place, there are no formal border control posts, you have to go on arrival from Iquitos to the immigration office in Santa Rosa to get the Peruvian exit stamp, a pre-condition for subsequently getting entry into Colombia or Brazil. We were almost the first ones there at the office and the exit process took about 5 minutes. Then it was down to the boats that take you across to Leticia (in Colombia) or neighbouring Tabatinga (in Brazil). It’s a short crossing, I had read a couple of months earlier that in the worst moments of the drought people were able to cross on foot. That’s no longer the case, but the creek taking us in to Leticia had barely enough water to permit incoming and outgoing boats to get past each other.

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.

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.

Hallo liebe OSM-Community,

Ich habe eine Frage zur Way-ID w495766634. Dort ist ein Seitenstreifen mit eingeschränktem Halteverbot mit Zeitraum, außerdem zwei Plätze zum Laden von Elektrofahrzeugen.

Hier die Bildquelle: https://www.mapillary.com/app/?lat=50.112034146849&lng=8.675660201024584&z=18.480623101734352&dateFrom=2024-05-01&pKey=2075065642879151&focus=photo&x=0.46802394290499305&y=0.48925073560159726&zoom=1.4021777417324663

Bisher habe ich folgendes getagged: parking:left:access=yes @ (Mo-So 0:00-07:00,17:00-24:00) parking:left:fee=no parking:left:maxstay:conditional=3 hours @ (08:00-21:00) parking:left:restriction=charging_only parking:left:restriction:conditional=no_parking @ (Mo-So 07:00-17:00)

Für mich impliziert das aber eher, dass der Parkraum nur für Elektrofahrzeuge zur Verfügung steht. Außerdem gilt maxstay in diesem Fall ja auch nur für E-Fahrzeuge und nicht für den Rest. Alles nicht richtig und nicht falsch meiner Meinung nach.

Wie würdet ihr diese Situation taggen, damit sie “korrekt” ist? Über Antworten würde ich mich sehr freuen.

Beste Grüße Simon
